Fire detection

The Series 65 range of conventional detectors incorporates well-proven sensing technologies, together with advances in materials and electronics technology. The A1R heat detector operates by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. In normal conditions, the two

WCP outdoor call points are designed for use in extreme weather conditions, with an operating temperature range of -30°C to +70°C. WCP models are available with configurations compatible with all conventional panels and intelligent versions are offered to meet specific requirements. The WCP range is approved to EN 54-11: most products are offered

The XP95 ionisation smoke detector uses irradiated air in the dual sensing chambers to produce ions that travel to the positive and negative electrodes, creating a current flow. As smoke enters the outer chamber, the flow drops and voltage increases. The voltage is measured and an analogue signal is converted to digital for transmission to the

This can help systems comply with the

Apollo manufactures Interfaces, a comprehensive range of intelligent systems. They enable fire protection systems to be engineered simply and effectively without the need for custom-designed equipment. The zone monitor powers and controls the operation of a zone of up to 20 Apollo Series 65 or Orbis fire detectors from a Discovery or XP95 loop

XPander is a wireless intelligent detector range in which individual alarm devices communicate with the XP95 loop by radio signals. Every device is assigned an address and this address is recognised by the control panel in the same way as is the address of any device connected directly to the loop wiring. The XPander rate-of-rise heat detector

AlarmSense is a range of conventional detection and alarm products specially designed to be connected to the same pair of supply wires. Providing an alarm between 70 and 87dB(A), the AlarmSense sounder beacon base will detect the removal of a detector head and report a fault. It continues to work during unauthorised removal of detectors. Quick and

Apollo manufactures Interfaces, a comprehensive range of intelligent systems. They enable fire protection systems to be engineered simply and effectively without the need for custom-designed equipment. The switch monitor from the Miniature range is designed to monitor the state of one or more single-pole, volt-free contacts connected on a single

The XP95 heat detector has a low air-flow resistant case for good contact between the sensing thermistor and the surrounding air. Temperature is measured by a single thermistor network which gives a voltage output proportional to the external air temperature. The signal is processed and transmitted to the control equipment

The Discovery multisensor detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value. The multisensor is useful over a wide range of applications and is highly immune to false alarm sources

XPander is a wireless intelligent detector range in which individual alarm devices communicate with the XP95 loop by radio signals. Every device is assigned an address and this address is recognised by the control panel in the same way as is the address of any device connected directly to the loop wiring. The XPander Manual Call Point is compliant

The Series 65 range of conventional detectors incorporates well-proven sensing technologies, together with advances in materials and electronics technology. The Series 65 standard relay base provides one set of volt-free changeover (from C) contacts that change state when the detector signals an alarm. Features: Advanced electronic technology

AlarmSense is a range of conventional detection and alarm products specially designed to be connected to the same pair of supply wires. The AlarmSense manual call point is compliant with EN54:11. It is different from other conventional call points in that it can be detected as an operated call point rather than a detector that has changed to the

The Series 65 range of conventional detectors incorporates well-proven sensing technologies, together with advances in materials and electronics technology. The optical smoke detector uses an internal pulsing LED and a photodiode at an obtuse angle. In the event of smoke entering the chamber, the light pulse from the LED will be scattered and

The XP95 optical detector uses an internal pulsing LED and a photo-diode at an obtuse angle. In the event of smoke entering the chamber, the light pulse from the LED will be scattered and registered by the photo-diode. A signal is generated and transmitted digitally to the control equipment

The Discovery optical smoke detector uses an IR LED that pulses light across a smoke chamber with a photodiode set at an obtuse angle. In clear air it receives no light, but when smoke enters the chamber, light from the LED is scattered onto the photodiode. A signal is then processed to provide an analogue value for transmission when the detector
