Fire Detector Brand & Capability Comparison

A cross-brand technical comparison of the automatic fire detectors offered by the six manufacturers most commonly encountered in the Australian and New Zealand market: Siemens Cerberus PRO, Ampac, Notifier (AFP-3030), Simplex TrueAlarm, Pertronic and Vigilant MX. It focuses on the detectors themselves — sensing technology, signal processing, loop protocol, range breadth and serviceability — with the host panel discussed only where it is inseparable from detector behaviour. Aligned to the AS 7240 / AS 1670 / AS 1851 servicing context.

Scope & method

This guide compares the automatic fire detector offerings of six manufacturers commonly encountered in the Australian and New Zealand market: Siemens Cerberus PRO, Ampac, Notifier (AFP-3030 platform), Simplex (TrueAlarm), Pertronic, and Vigilant (MX range on the MX1 platform). The focus is on the detectors themselves — sensing technology, signal processing, protocol, range breadth and serviceability — rather than on control-and-indicating equipment, although the host panel is discussed wherever it is inseparable from detector behaviour.

The single most important structural distinction between these brands is communication protocol. A detector is only as “intelligent” as the loop it speaks on and the panel that interprets it. Two of the six brands (Ampac and Pertronic) do not manufacture their own detector silicon at all — they run the Apollo analogue-addressable ecosystem (XP95 / Discovery / Soteria). The other four each run a proprietary protocol that ties the detector to that vendor’s panels. This has direct consequences for spare-parts interchangeability, cross-brand servicing and long-term lock-in — points drawn out throughout.

A note on “Vigilant MX11”: there is no distinct Vigilant product marketed as “MX11”. The Vigilant addressable range is the MX (“MX Technology” / MX VIRTUAL) detector family that runs on the MX1 fire indicator panel, and this guide treats it as the Vigilant MX addressable detector range on the MX1 platform.

Methodology & currency: information is drawn from manufacturer datasheets, technical manuals, ActivFire listings and distributor documentation current as at mid-2026. Fire product ranges evolve — model supersessions, protocol revisions and standards updates are frequent — so any figure driving a design, tender or compliance decision should be confirmed against the current manufacturer datasheet and ActivFire certificate for the specific model and region.

Platform & protocol at a glance

This is the orientation map for everything that follows. Read the protocol column first: it determines who can supply and service the detectors.

Open vs proprietary: Ampac and Pertronic both sit on the Apollo protocol, so their smoke, heat and multisensor detectors are essentially the same physical devices from a common source, differentiated mainly by panel software and local support. Siemens, Notifier, Simplex and Vigilant each lock the detector to their own loop, which generally buys tighter integration and diagnostics at the cost of sole-source supply.

Sensing technology & signal processing

All six are true analogue-addressable systems: the detector reports a measured value (or values) and the panel applies thresholds, drift compensation and alarm logic in software. Where they diverge is in the sophistication of the on-board sensing and the intelligence of the algorithm layer.

Signal processing & multi-criteria
BrandSignal-processing signatureMulti-criteria / nuisance rejection
Siemens Cerberus PROASAtechnology (Advanced Signal Analysis) — event-controlled, application-specific parameter sets selectable per detector; marketed as “neural”.Dual optical (forward + backward scatter) + two heat sensors; redundant sensor system; strong deceptive-phenomena immunity; CO variant (OOHC740) adds a carbon-monoxide criterion.
Ampac (Apollo)Panel-side algorithms over Apollo analogue values; Discovery detectors carry five selectable response modes; drift compensation per Apollo capability.XP95/Discovery multisensor combines optical + thermistor; the Discovery mode set tunes the smoke/heat blend to the environment.
Notifier AFP-3030FlashScan all-digital grouped polling (fast re-interrogation of changing points); drift compensation + software smoothing; 24-hour automatic device self-test.Co-operative multi-detector sensing and alarm-delay facilities reduce unwanted alarms; VIEW laser option for very early warning.
Simplex TrueAlarmTrueAlarm analogue sensing — the raw value is sent to the panel, which stores a per-point average, applies drift compensation and logs peak values; seven sensitivity levels (0.2–3.7 %/ft).360° smoke entry; “Faster Fire Detection” CO-correlation mode lets a standard photo sensor behave like a higher-sensitivity one when CO is present.
Pertronic (Apollo)Panel-side processing over Apollo; Soteria adds digital CoreProtocol with a dynamic algorithm for transient rejection and drift compensation while holding sensitivity.Soteria PureLight optical (cone + high-intensity IR LED); multi-sensor optical/heat with five modes; tri-sensor optical/heat/CO option.
Vigilant MXMX DIGITAL protocol with the FASTLOGIC detection algorithm and SMARTSENSE (fuzzy-logic) option; a “detector dirty alert” flags approaching compensation limits for maintenance.MX VIRTUAL dual-sensor detectors (photo+heat or CO+heat) with up to seven detection modes including heat-enhanced smoke and heat-enhanced CO.

Reading this for servicing: every brand supports the automatic sensitivity monitoring and drift compensation that underpins AS 1851 detector-sensitivity verification — the panel logs each point’s condition and raises a “dirty/maintenance” warning before the detector drifts out of tolerance. The practical differences are in how the warnings are surfaced (Notifier’s three-tier maintenance alerts, Simplex’s per-point peak logging, Vigilant’s dirty-alert, Siemens’ parameter/condition reporting).

Siemens Cerberus PRO

Cerberus PRO is Siemens’ integrated fire platform; its detector line is the Cerberus PRO FS20 range. It is positioned as a premium, false-alarm-resistant system suited to large, complex or mission-critical sites, with a strong modernisation story — multi-protocol detectors can run on legacy Siemens loops during staged upgrades.

Detector range
DeviceDescription
OOH740 multisensorDual optical scatter (forward + backward) plus two heat sensors; software-configurable as multisensor, smoke-only or heat-only. The flagship device.
OOHC740 tri-sensorAdds a CO cell for optical + heat + carbon-monoxide evaluation and fast response to CO-generating fires.
OH720 / HI722Single-criterion optical smoke (OH720) and heat (HI722) variants sharing the same platform, base and diagnostics.
Special applicationFDF241-9 IR flame (3-channel), FDL241-9 linear beam, and FDA221 / FDA241 aspirating (ASD) within the same portfolio.
  • ASAtechnology with application-specific parameter sets — behaviour is tuned to the environment (car park, kitchen, clean room) rather than a single global sensitivity.
  • Redundant sensor system and an integrated line separator (isolator) in the detector head; a 360° internal alarm indicator that needs no alignment; suitable for wind speeds of 1–20 m/s.
  • Automatic addressing at commissioning; Ex (hazardous-area) variants via FDnet-Ex; cloud connectivity via Cerberus DMS / Cerberus Mobile as part of Siemens Xcelerator.

Trade-offs: premium pricing and a Siemens-partner supply and service channel. Powerful for large integrated estates; heavier than needed for a small standalone building.

Ampac

Ampac is an Australian manufacturer (Perth-based, a Halma company) best known locally for its FireFinder PLUS and LoopSense panels. Critically for this comparison, Ampac’s addressable detectors are the Apollo XP95 / Discovery range — Ampac and Apollo are both Halma companies, and the panels are built around the open Apollo protocol. This gives strong local support and Australian approvals combined with a widely-available, non-proprietary detector base.

Detector range (Apollo)
DeviceDescription
XP95Optical smoke, heat and optical/heat multisensor; XPERT-card addressing; low-insertion-force intelligent bases, isolating bases and base sounders/beacons (AS 7240.3 tones).
DiscoveryHigher-end multisensor with five selectable response modes and access to raw temperature data for enhanced processing.
FastSense (ASD)Laser-based high-sensitivity aspirating detection with the ClassiFire AI algorithm; SenseNET manages up to 126 detectors over RS-485 (to 1.2 km).
Xpander wirelessBi-directional monitored radio optical, heat and multisensor detectors and MCPs with multi-year battery life, for heritage or wiring-restricted sites.
  • Open Apollo protocol: detectors are readily available from multiple sources and interchange with other Apollo-based panels (including Pertronic) — a real advantage for spares and long-term serviceability.
  • Australian manufacturer with local engineering, AS 7240 / AS 1603 / AS 4428.3 approvals and ActivFire listings; FireFinder PLUS scales to 8 loops and networks up to 99 nodes.

Trade-offs: detector “intelligence” is bounded by the Apollo protocol and the panel’s algorithms rather than bespoke on-board silicon, so the very newest multi-criteria features (e.g. CO tri-sensors) depend on running the current Apollo Soteria generation and a panel that supports it.

Notifier AFP-3030

The AFP-3030 is Notifier’s (Honeywell) intelligent panel — in the Australian market an Onyx-series FACP listed to AS 7240.2 and AS 7240.4. Its detectors are the 851/951 FlashScan family. Notifier is strong in large networked commercial and high-rise projects and is deployed through a broad integrator channel.

Detector range
DeviceDescription
FSP/FSI/FST-851Low-profile 851 family — FSP-851 photoelectric, FSI-851 ionisation, FST-851 thermal (fixed / rate-of-rise) — with rotary decimal addressing.
FSL-751 VIEWLaser photoelectric detector for very-early-warning applications.
FSP-951 seriesModern replacement generation with an enhanced optical chamber; FSP-951T adds thermal, FSP-951R is remote-test for duct housings.
Intelligent basesSounder bases (B200S, Temporal-3 capable), plus relay and isolator bases.
  • FlashScan all-digital protocol uses grouped polling: when a point changes, the CPU concentrates on it, giving markedly faster response than sequential polling. Dual-protocol detectors also run legacy CLIP.
  • Capacity: up to 159 detectors + 159 modules per SLC (318 devices/loop, 3,180 per node); Noti-Fire-Net to 102 nodes (High-Speed to 200).
  • Drift compensation with software smoothing, a 24-hour automatic device self-test, three-tier maintenance warnings (chamber value / maintenance alert / maintenance urgent), alarm-delay and co-operative detection; VESDAnet integration via SLC-IM.

Trade-offs: proprietary detectors, but a wide installer and service base in Australia. Very capable on large networked sites, and the drift-compensation and self-test features map neatly onto AS 1851 routine servicing.

Simplex TrueAlarm

Simplex (Johnson Controls) TrueAlarm is a long-established premium proprietary platform, common in hospitals, universities and large institutional estates. The defining idea is that the detector is a pure analogue sensor and virtually all intelligence lives in the panel.

Detector range
DeviceDescription
4098 TrueAlarm sensors4098-9714 / 9701 photoelectric smoke sensors (pulsed LED + silicon photodiode, 360° smoke entry), plus ionisation, thermal and 4098 laser variants.
Multi-sensor & CO basese.g. 4098-9754 multi-sensor and CO bases that layer additional sub-points under one address.
QuickConnect24098-9757 combined sensor/base assemblies to speed installation.
  • TrueAlarm analogue sensing: the panel keeps a running per-point average, performs automatic environmental (drift) compensation and logs peak values individually — directly supporting NFPA 72 / AS 1851 sensitivity monitoring without pulling detectors for lab testing.
  • Seven selectable sensitivity levels from 0.2 % to 3.7 %/ft obscuration, chosen and monitored at the panel.
  • “Faster Fire Detection” mode uses CO correlation so a photo sensor set at a conservative 2.5 %/ft can behave closer to 0.5 %/ft when CO is present — earlier warning without the nuisance penalty of a permanently high-sensitivity setting.
  • Communicates over IDNet or MAPNET II, auto-selected.

Trade-offs: the most closed of the six — Simplex detectors, panels and service are effectively single-source (Johnson Controls / authorised partners). Excellent per-point analytics and reliability; least flexible on competitive spares.

Pertronic

Pertronic is an Australasian manufacturer (New Zealand, with Australian branches since 1999) whose F100A / F120A / F220 panels protect a large share of ANZ high-rise and infrastructure. Like Ampac, Pertronic runs the open Apollo detector ecosystem, so its detectors are XP95 / Discovery / Soteria. Its differentiation is at the panel and configuration layer, plus strong local engineering support.

Detector range (Apollo)
DeviceDescription
XP95 & DiscoveryOptical, heat and multisensor detectors, as per the Apollo range described for Ampac.
Soteria (PureLight)Apollo’s current generation: cone-optics with a high-intensity IR LED, an in-head short-circuit isolator, five operating modes and digital CoreProtocol; a tri-sensor optical/heat/CO version is available. Backwards-compatible with XP95/Discovery loops (with some feature limitations).
  • F220 flagship: a 7″ 800×480 colour display driven by a modern ARM/RISC processor; FireUtils Windows configuration with spreadsheet-style cause-and-effect editing — noted by installers for information clarity and programming speed.
  • Serious scale and networking: F120A to 20 loops / 5,160 devices; Net2 networks tested to 130 nodes and deployed at that scale (large tunnel and correctional projects); total networked capacity beyond 40,000 addresses.
  • Shares the open-Apollo spares advantage with Ampac — detectors interchange across Apollo-based platforms, easing long-term maintenance.

Trade-offs: as with Ampac, on-loop detector intelligence is Apollo-bounded; the strongest reasons to choose Pertronic are panel capability, configuration flexibility and local support rather than a unique detector.

Vigilant MX (MX1 platform)

Vigilant is Johnson Controls’ heritage ANZ brand (founded 1914). The MX1 is its analogue-addressable panel; the detectors are the MX “VIRTUAL” multi-sensor range running the MX DIGITAL protocol. It is positioned for small-to-large ANZ systems, including hazardous areas, and is widely specified as a non-proprietary open-market panel for staged upgrades from collective detection.

Detector range
DeviceDescription
814 series814P (photo), 814PH (photo+heat) and 814CH (CO+heat) dual-sensor detectors.
850 series850P / 850PH / 850H equivalents; the MX VIRTUAL multi-sensor concept lets one detector present multiple “virtual” points (e.g. smoke and heat) mapped to different zones or functions.
Special applicationAlso supports VESDA ASD (via interface), flame detectors and Ex-rated devices on the same MX loop.
  • Selectable detection modes per detector: CO+heat, heat-enhanced CO, smoke+heat, heat-enhanced smoke, or single-criterion CO / smoke / heat — chosen to optimise detection vs nuisance rejection location by location.
  • FASTLOGIC / SMARTSENSE fuzzy-logic algorithms; a “detector dirty alert” logs when drift-compensation limits are approaching, prompting maintenance.
  • MX DIGITAL is designed for high fault tolerance over many cable types — a genuine advantage when re-using existing cable during a collective-to-addressable upgrade. MX1: up to 250 MX devices/loop, expandable to 8 loops; complies with AS 7240.2/.4, AS 4428.3, NZS 4512 (ActivFire AFP-2320).

Trade-offs: proprietary MX detectors tied to Vigilant / JCI panels, but a strong ANZ standards pedigree, local support and an easy upgrade path from legacy collective systems.

Multi-criteria (multisensor) detectors

Multisensor detectors are where the brands most visibly differentiate, because combining criteria (optical + heat + CO) is the primary lever for early detection with low false alarms.

Flagship multisensor detectors
BrandFlagship multisensorCriteria combinedCO option?
SiemensOOH740 / OOHC740Dual optical scatter + 2× heat (+CO)Yes (OOHC740 tri-sensor)

Vigilant814PH / 814CH (MX VIRTUAL)Photo+heat OR CO+heat, up to 7 modesYes (814CH CO+heat)

Special-application detection

Beyond point detectors, each ecosystem offers aspirating, beam and flame options — either in-house or via interface.

Special-application detection
BrandAspirating (ASD)Beam / linearFlame

Note: Xtralis VESDA aspirating detection is effectively brand-agnostic — it appears across most platforms via a high-level interface or relay/monitor module, so ASD choice is rarely a reason to select a point-detector brand. For a full breakdown, see the aspirating smoke detection guide.

Australian standards, approvals & servicing

For an Australian servicing and maintenance context, the relevant framework is AS 7240 (product/system), AS 1670 (system design) and AS 1851 (routine service of fire protection systems), with detectors and CIE requiring ActivFire (CSIRO) listing. All six brands carry current ANZ approvals for their addressable detector ranges; the practical differences are in supply channel and in how each surfaces the data AS 1851 servicing relies on.

Supply channel & serviceability
BrandSupply / service channelAS 1851-relevant serviceability
SiemensSiemens Solution Partners (managed channel)ASA parameter sets + CAM tooling; drift compensation; detector-condition reporting.
AmpacAustralian manufacturer; broad Apollo detector supplyOpen Apollo spares; panel logs detector condition; XPERT addressing eases swaps.
NotifierWide Honeywell integrator base in AU24-hr self-test; 3-tier maintenance alerts; per-point drift data — strong service fit.

PertronicAustralasian manufacturer; open Apollo detectorsOpen Apollo spares; FireUtils reporting; detector-condition logging.
VigilantJCI / Tyco ANZ channel“Detector dirty alert”; FASTLOGIC; MX DIGITAL tolerant of legacy cable on upgrades.

The spares question in one line: if minimising sole-source risk and keeping detector spares competitive over a 15–20 year service life matters to the client, the two Apollo-based brands (Ampac and Pertronic) are structurally advantaged. If the priority is the tightest possible per-point analytics and integration, the proprietary platforms (Simplex TrueAlarm, Notifier FlashScan, Siemens ASA, Vigilant MX DIGITAL) each make a strong case — at the cost of channel lock-in.

Selection guidance — choose by scenario

No single brand “wins” — the right choice is driven by site scale, the existing installed base, the false-alarm sensitivity of the environment, and how much the client values open spares versus deep proprietary analytics.

  • Large / complex / mission-critical estate wanting premium false-alarm immunity and cloud oversight → Siemens Cerberus PRO (ASAtechnology, tri-sensor CO, Ex, DMS).
  • Australian project prioritising open detector spares + local manufacturer support → Ampac or Pertronic (both Apollo). Pertronic’s F220 leads on display, programming and very large networks; Ampac offers a clean AU-made panel line plus FastSense ASD and Xpander wireless in-house.
  • Large networked commercial / high-rise with a broad integrator pool → Notifier AFP-3030 (FlashScan speed, big node counts, strong maintenance reporting).
  • Institutional estate valuing best-in-class per-point analytics and reliability, single-source accepted → Simplex TrueAlarm.
  • Staged upgrade from a legacy collective system, re-using existing cable, ANZ standards focus → Vigilant MX1 (MX DIGITAL cable tolerance, VIRTUAL multi-mode detectors, F3200 lineage).

The two decisions that matter most

Two choices outlast the install and dominate lifecycle cost and performance:

  • Protocol / spares strategy — open (Apollo: Ampac, Pertronic) vs proprietary (Siemens, Notifier, Simplex, Vigilant). This outlives the install and drives lifecycle cost and sole-source risk.
  • Multi-criteria need — if the environment is nuisance-prone or needs CO sensing, weight the tri-sensor / multi-mode capability (Siemens OOHC740, Apollo Soteria tri, Simplex CO base, Vigilant 814CH, Notifier CO variants) rather than the badge.

No brand is universally best. The two Apollo-based brands (Ampac, Pertronic) win on open spares and long-term serviceability; the four proprietary platforms (Siemens, Notifier, Simplex, Vigilant) each offer deeper per-point analytics and tighter integration in exchange for single-source supply. Match the protocol strategy and multi-criteria need to the site, then confirm the specific models against current datasheets.

Disclaimer & currency: compiled from manufacturer datasheets, technical manuals, ActivFire listings and distributor documentation current as at mid-2026. Model ranges, protocol revisions and standards references change frequently; confirm any figure against the current manufacturer datasheet and ActivFire certificate for the specific model and region before relying on it for design, tender or compliance purposes.

Frequently asked

Which fire detector brands use the open Apollo protocol?

Ampac and Pertronic both run the open Apollo analogue-addressable ecosystem (XP95 / Discovery / Soteria) rather than manufacturing their own detector silicon, so their smoke, heat and multisensor detectors are essentially the same devices from a common source. The other four — Siemens, Notifier, Simplex and Vigilant — each use a proprietary protocol that ties the detector to their own panels.

Is there a Vigilant “MX11” detector?

No. There is no distinct Vigilant product marketed as “MX11”. The Vigilant addressable range is the MX (“MX Technology” / MX VIRTUAL) detector family that runs on the MX1 fire indicator panel over the MX DIGITAL protocol.

Open (Apollo) vs proprietary protocol — which is better?

Neither wins outright. Open Apollo (Ampac, Pertronic) gives competitive spares, second-sourcing and cross-panel interchange — a real advantage over a 15–20 year service life. Proprietary loops (Siemens ASA, Notifier FlashScan, Simplex TrueAlarm, Vigilant MX DIGITAL) buy tighter integration and richer per-point diagnostics at the cost of single-source supply. Choose based on whether spares flexibility or deep analytics matters more to the client.

Which brands offer CO (tri-sensor / multi-criteria) detectors?

All six offer a CO or multi-criteria option: Siemens OOHC740 tri-sensor, Apollo Soteria tri-sensor (Ampac and Pertronic), Notifier CO variants/bases, Simplex CO sensor base, and Vigilant 814CH (CO+heat). Combining optical, heat and CO is the primary lever for early detection with low false alarms.

How do these detectors support AS 1851 servicing?

Every brand supports automatic sensitivity monitoring and drift compensation, so the panel logs each point’s condition and raises a “dirty/maintenance” warning before a detector drifts out of tolerance — supporting AS 1851 detector-sensitivity verification without pulling detectors for lab testing. They differ mainly in how alerts are surfaced: Notifier’s three-tier maintenance warnings, Simplex’s per-point peak logging, Vigilant’s dirty-alert and Siemens’ parameter/condition reporting.
