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 on construction or refurbishment sites.
Traditionally fire detection systems are installed once the building is complete and the main services are installed, yet it is still important to protect the building from major damage by fire during fit-out and alteration.
XPander can be used as part of an extension to a fixed fire system, so is ideal where works are ongoing as an extension or where temporary structures are in place. Buildings undergoing fire system refurbishment can also benefit from wireless devices: in this case the wireless fire detectors are used to provide temporary cover until the old fire system is decommissioned and a new hard-wired fire system can be installed.
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.
Apollo’s wireless XPander has been designed to be used in conjunction with a standard fire detection system, being able to protect areas that require wireless technology. XPander has an updated 31-device loop interface and connects to an XP95-compatible control 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.
