Apollo Smoke Detectors

An Apollo smoke detector is a fire alarm detector head that reports to a control panel rather than sounding on its own. This collection covers Apollo optical smoke detectors across its ranges: XP95 and Discovery addressable heads, Soteria and Soteria Dimension detectors, AlarmSense two-wire, REACH Wireless and an XPander head, for addressable, two-wire and wireless systems, with EN54-7 cited on models such as the Discovery 58000-600APO.

Choosing Apollo Smoke Detectors

The Apollo range you choose depends on the panel protocol and wiring already in place, so start from the system rather than the detector.

Addressable loop detectors

XP95 optical heads, such as the 55000-600APO and 55000-620APO, and the Discovery 58000-600APO at 17-28 V report individually on an addressable loop, so the panel names the device in alarm. Soteria detectors such as the SA5100-600APO use Apollo's CoreProtocol and PureLight sensing.

Specialist Soteria Dimension

The Soteria Dimension FL5100-660APO is chamberless and flush mounted, a low profile detector with an integrated switchable isolator, and the FL6100-600APO is certified to DHF TS001 for anti-ligature use in specialist areas.

Two-wire and wireless

AlarmSense heads such as the 55000-390APO run on a two-wire system at 9-33 V DC. The REACH Wireless RW1000-660APO is a wireless addressable detector for buildings where cable cannot be run, and the XPA-CB-12034-APO is from Apollo's XPander range.

Standards & compliance

EN54-7 is the standard for point smoke detectors in fire alarm systems, and it is cited on the Discovery 58000-600APO, AlarmSense 55000-390APO and Soteria Dimension FL6100-600APO in this range.

Frequently asked questions

What is the difference between Apollo XP95 and Discovery?

XP95 and Discovery are Apollo addressable detector ranges whose heads report individually on a loop. The XP95 optical heads here include the 55000-600APO and 55000-620APO, and the Discovery optical head is the 58000-600APO at 17-28 V. Use the range your panel and existing detectors are built around.

What is Apollo Soteria?

Soteria is an Apollo detector range using CoreProtocol digital communication. The SA5100-600APO optical detector uses PureLight sensing for false alarm management, the Soteria Dimension FL5100-660APO is chamberless and flush mounted, and the FL5100-660APO and FL6100-600APO each have an integrated switchable isolator.

Is there an anti-ligature smoke detector?

Yes. The Apollo Soteria Dimension FL6100-600APO specialist optical detector is certified to DHF TS001 for anti-ligature use, for specialist areas where a standard detector head could be used as a ligature point. It has a ruggedized metal face plate secured with anti-tamper screws and an integrated switchable isolator.

Can Apollo smoke detectors be wireless?

Yes. The Apollo REACH Wireless RW1000-660APO is a wireless addressable optical smoke detector with a dual-optical chamber, for buildings where running loop cable to detector positions is impractical. It has twin alarm, bi-colour LEDs, dual-channel redundancy and a ten-year battery life.

What is Apollo AlarmSense?

AlarmSense is Apollo's two-wire detection range. The 55000-390APO AlarmSense optical smoke detector runs at 9-33 V DC and is EN54-7 certified, for residential and small-to-medium commercial installations using an AlarmSense-compatible panel, such as bedrooms, escape routes, care homes and HMOs.

Do Apollo detectors sound an alarm themselves?

No. Apollo detectors report to a fire alarm control panel, which operates the sounders and beacons. This is the difference from a domestic smoke alarm, which has its own sounder. For self-contained alarms see the smoke alarms and detectors collection.

Are all the Apollo smoke detectors here optical?

In this range, the XP95 55000-600APO, Discovery 58000-600APO, Soteria SA5100-600APO and REACH RW1000-660APO are optical smoke detectors. The 55000-390APO, 55000-600APO, 55000-620APO and 58000-600APO state the light scatter principle, suited to slow-burning and smouldering fires, and the Soteria Dimension FL5100-660APO is chamberless.

Do Apollo smoke detectors fit a base?

The AlarmSense and XP95 heads do. The AlarmSense 55000-390APO fits a compatible AlarmSense two-wire base, and on the XP95 55000-600APO a coded card inserted in the base gives the detector's location, read by any detector plugged in. The Soteria Dimension FL5100-660APO is flush mounted instead.
