Brand Information
XPander incorporates entirely new designs with respect to the wireless communication system. A Radio Interface is connected to the loop. It communicates with the control panel using the Apollo addressable two-wire power and communications system. The interface communicates with the detection and alarm signalling devices by means of radio waves. The detectors are multistate in that they report normal, pre-alarm, fire or fault states to the radio base which transmits the information to the interface. The detectors incorporate drift compensation and report any compensation limit occurring. The radio bases and signalling devices are addressable and use a pre-set analogue value to report via the XP95 or Discovery protocol. Apart from normal and fire the bases can send pre-set analogue values to indicate low battery, detector contaminated, detector tamper and low signal strength fault conditions.
Brand Features
modern styling loop-powered interface operating on 868MHz wireless addresses seen by control panel as normal addresses radio base with wireless circuitry and battery compartment chamber designed to inhibit dirt penetration and thus reduce false alarms automatic drift compensation with DirtAlert™ warning algorithms for transient alarm rejection FasTest™ reduces time taken to test detectors remote test facility 3-5 years battery life
Electrical Considerations
The Apollo XPander EN54-11 certified manual call point (MCP) is supplied with 2 packs of 3 'AA' alkaline batteries which provide a working life of typically 3-5 years.
Operating Principles
An alarm LED is provided on the call point. This LED is controlled, independently of the call point, by the control panel. The red LED is lit when the call point has been activated. Call points can be remotely tested from the panel by transmission of a single bit in the communications protocol. Call points respond by providing a value of 64 which corresponds to the alarm value. XPander Manual Call Points are supplied with a resettable operating element as standard. The call point uses the "priority interrupt" feature to give a fast response on operation. This product is tested and approved to the EN54-11 standard.
Communication
Radio Communications Fire detection systems are life-saving systems and must, therefore, be highly reliable in use. Radio communications have been developed to a point where high reliability can be guaranteed, provided that the rules for the design of radio systems and installation are carefully observed. Radio communication technology in the detection has matured to the point where a standard has been drawn up as part of the EN54 family of standards for components of a fire detection system. The standard is EN54 Part 25. Frequency The frequency used by XPander is 868MHz which is the harmonised European radio frequency.
Maintenance & Service
Detectors should be checked regularly at the intervals indicated by the locally applicable code of practice. Apollo recommends that the detectors be checked at least once a year. If detectors appear not to be functioning correctly they should be returned to Apollo for testing. If detectors are externally dirty they can be cleaned carefully with a damp cloth using a small amount of industrial alcohol.
Product Information
The XPander Manual Call Point is compliant with EN 54-11. It is wireless and is powered by two independent packs of three AA alkaline batteries with a typical five year life.
