Apollo Fire Detection & Alarm Equipment

Apollo makes fire detection devices for addressable and conventional fire alarm systems, and this page lists its range: XP95, Discovery and Orbis smoke, heat and multisensor detectors, AlarmSense two-wire devices, flame and beam detectors, detector and sounder bases, open-area sounders and visual alarm devices, interface and switch monitor modules, and accessories such as address cards, call point covers and reset keys.

Choosing Apollo Fire Detection & Alarm Equipment

Start with the fire panel: XP95 and Discovery devices sit on an addressable loop, while AlarmSense devices run on a two-wire conventional circuit.

Detectors

Optical smoke detectors such as the Discovery 58000-600APO use a light-scatter chamber to pick up slow-burning and smouldering fires, with five selectable response modes. Where smoke detection is unsuitable, heat detectors respond to temperature instead: the XP95 55000-400APO alarms at about 55°C, and the 55000-401APO at 90°C suits car parks, loading bays and kitchens. Multisensors such as the 55000-885APO combine photo-electric smoke and thermistor heat sensing to reduce nuisance alarms. For special risks, the 55000-020APO flame detector senses the flickering infra-red of flames, and the SA7100-100APO is an auto-aligning reflective beam detector.

Sounders and visual alarms

The 55000-001APO open-area sounder is loop-powered on an isolating 4" base, with selectable tones and volume settings of 92 dB(A) and 100 dB(A). Sounder VAD bases such as the 45681-705APO combine a sounder and a white-flash visual alarm device with a built-in isolator. Where tones may be masked by background noise, or to alert hearing-impaired people, VADs give a 0.5 Hz white flash: the 55000-744APO for walls (EN 54-23 W-2.4-6) and the 55000-745APO for ceilings (Category C).

Bases, modules and accessories

The XPERT 7 isolating base 45681-284APO automatically isolates short-circuit faults on loops and spurs, and XPERT address cards such as the 45682-800APO set a detector address by removing numbered pips. Modules link other equipment to the loop: the SA4700-102APO supervises volt-free contacts and switches changeover relay outputs, and the 55000-760APO mini switch monitor mounts on a 35 mm DIN rail. The 55000-982APO electromagnetic door holder connects directly to the addressable loop, so the panel can close fire doors in alarmed areas.

Frequently asked questions

What types of detector does Apollo make?

Apollo makes smoke, heat, multisensor, flame and beam detectors for commercial fire alarm systems. Optical smoke heads suit smouldering fires, heat detectors suit kitchens and dusty areas, and multisensors help cut nuisance alarms. Its families cover addressable loops, conventional circuits and two-wire systems such as AlarmSense. The range here includes detectors, bases, sounders and interface modules.

Does Apollo make fire alarm panels?

No, Apollo concentrates on detectors, sounders, call points and loop interface devices rather than control panels. Its addressable and two-wire protocols are built into panels from other manufacturers, so a panel must support the right Apollo protocol. Confirm compatibility with the panel maker before adding devices to a loop. The range here includes call points, isolators and input/output modules.

How do you set the address on an Apollo detector?

On many Apollo addressable systems, the address is set with an XPERT card that clips into the detector base. The installer removes numbered pips to code the address, and the head reads it when fitted, so a replacement head keeps the same address. Some loop devices, such as modules and sounders, use a DIL switch instead. The range here includes XPERT address cards.

What are Apollo intrinsically safe detectors?

Intrinsically safe detectors are made for hazardous areas where flammable gas, vapour or dust may be present. They limit the electrical energy in the circuit so a fault cannot cause ignition, and they must be installed with a suitable safety barrier or galvanic isolator. Apollo makes intrinsically safe heat detectors in the Orbis family. The range here includes intrinsically safe heat detectors.
