XPander heat detector and mounting base
Visit site
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 detectorXP95 optical smoke detector
Visit site
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- PRODUCT

Discovery optical smoke detector
Visit site
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 detectorXP95 multisensor detector

Visit site
The Series 65 range of conventional detectors incorporates well-proven sensing technologies, together with advances in materials and electronics technology. The ionisation smoke detector irradiates air in the dual sensing chambers to produce ions that travel to the positive and negative electrodes, creating a current flow. As smoke enters theXP95 ionisation smoke detector
Visit site
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 theDiscovery intelligent mounting base
Visit site
The Discovery intelligent mounting base requires only a low insertion force for installation, making it suitable for use on suspended ceilings. It has stainless steel contacts for the detector terminals and is supplied with an XPERT card. All detectors in the Discovery and XP95 ranges fit into the intelligent mounting base- PRODUCT

Discovery carbon monoxide detector
Visit site
The Discovery carbon monoxide (CO) fire detector contains a long-life electrochemical CO sensor. The sensing technology is fast, accurate and needs only very low power. It does not detect smoke particles or heat and are is not a universal replacement for smoke detectors. CO fire detectors are electronic detectors that can indicate the outbreak ofAlarmSense heat detector
Visit site
AlarmSense is a range of conventional detection and alarm products specially designed to be connected to the same pair of supply wires. The AlarmSense 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 thermistorsXP95 heat detector
Visit site
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 equipmentDiscovery isolating base
