Apollo XP95 Optical Smoke Detector
Summary
The Apollo XP95 Optical Smoke Detector utilises advanced photo-electric light scatter technology to provide reliable fire detection for applications where slow burning or smouldering fires are anticipated. Operating on the principle of forward light scatter detection, the detector features a horizontal optical bench housing an infrared emitter and sensor arranged radially to detect light scattered by smoke particles.
Designed with versatility in mind, the XP95 Optical Smoke Detector is compatible with XP95, Discovery and CoreProtocol fire alarm systems, offering flexible integration options. The detector operates effectively across a wide temperature range from -20°C to +60°C and remains unaffected by environmental factors such as wind speed and atmospheric pressure, making it suitable for diverse installation environments including escape routes and critical areas requiring dependable smoke detection.
The detector features a distinctive clear LED indicator that emits red light during alarm conditions, housed within a white flame-retardant polycarbonate case measuring 100mm in diameter. With low power consumption and polarity-insensitive two-wire connection, the XP95 Optical Smoke Detector delivers professional-grade fire detection with straightforward installation and maintenance requirements.

FAQ
What type of fires is the XP95 Optical Smoke Detector best suited for?
The XP95 Optical Smoke Detector is ideal for detecting slow burning or smouldering fires. It uses the light scatter principle, making it particularly effective at identifying smoke from fires that develop gradually rather than flaming fires.
Is the detector suitable for use in escape routes?
Yes, the XP95 Optical Smoke Detector is well suited to escape routes. Its reliable detection of smouldering fires and unaffected performance in varying environmental conditions make it an excellent choice for protecting evacuation pathways.
What fire alarm systems is this detector compatible with?
The XP95 Optical Smoke Detector is compatible with XP95, Discovery and CoreProtocol fire alarm systems, providing flexible integration options for various installations.
Can environmental conditions affect the detector’s performance?
No, the detector is designed to be unaffected by wind speed and atmospheric pressure. It operates effectively across temperatures from -20°C to +60°C and in humidity levels from 0% to 95% RH (without condensation or icing).
Can I connect a remote LED indicator to the detector?
Yes, the XP95 Optical Smoke Detector provides connection points (+R and -R terminals) for a remote LED indicator. The indicator must be a standard high-efficiency red LED requiring not more than 4mA at 5V, and does not require a series limiting resistor as current is limited within the detector.
What is the power consumption of the detector?
The detector has a low quiescent current of 340 µA. During power-up, there is a surge current of 1mA for 1 second. When in alarm, the LED draws 4mA, and a remote LED draws a maximum of 5mA.
How is the detector wired to the fire alarm system?
The detector uses a simple two-wire supply connection that is polarity insensitive. It connects to the incoming and outgoing supply via terminals L1 and L2 in the mounting base, operating from a supply voltage of 17V to 28V DC.
What colour options are available?
The XP95 Optical Smoke Detector is available in white (part numbers 55000-600 and 55000-620) and black (part number 55000-660), allowing it to blend with different interior designs.
