Wireless Fire Detection with XPander
Apollo has updated and extended its XPander range of wireless
fire detectors. Designed for use in areas where hard-wired fire
detection is impossible or impractical, XPander devices are ideal
for use in educational buildings such as schools and
universities.
Educational establishments may typically consist of a number of
buildings that are spread across a site, such as sports centres and
exterior classrooms. Linking these buildings back to the main fire
detection system can be expensive or impractical depending on
distance and the large amount of cabling required. Apollo's
wireless XPander range solves this problem.
The extended XPander range includes two new products and now
consists of an optical smoke detector, a multisensor smoke
detector, heat detector types A1R and CS, a wireless base, a manual
call point, a sounder and a sounder beacon and Single and Dual
Input/Output Units. The complete range has been granted the new
wireless link fire standard EN54 Part 25, which is the standard for
European-compliant radio products.
XPander has an updated 31-device loop interface and connects to
an XP95-compatiblecontrol panel via an interface which is wired to
the loop. No special adjustment or programming is required and the
devices are recognised by the control panel simply as another
detector connected to the system. The detectors are multi-state in
that they report normal, fire or fault states to the radio base,
which transmits the information to the interface. The radio bases
and signalling devices are addressable and use a pre-set analogue
value to report via the XP95 protocol. In addition to 'normal' and
'fire' signals, the bases can also indicate a low battery, a dirty
detector, detector tamper and low signal strength fault
conditions.
