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 Input/Output Unit is a radio based interface and offers two monitored input circuits and two relay outputs. It can be used for controlling fire doors, fire dampers, smoke vents and other fire engineering applications.
