The new XPander range of wireless intelligent fire detectors from Apollo is designed for use where wired detectors are either impractical or undesirable. Only available to companies who have had their engineers trained by Apollo in the use of wireless detectors, the XPander was developed to enhance the capabilities of Apollo’s existing XP95 detector range. It comprises an interface, 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.
Using the XPander is very simple – the devices are simply connected to an XP95-compatible control panel via an interface which is wired in the loop. No special adjustment or programming is required: once connected, the XPander devices are recognised by the control panel as another detector connected to the system. Up to 15 devices can be installed per interface, with up to five interfaces per loop.
The detectors are conventional 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. The bases can also indicate if battery power is low, if a detector is dirty or been tampered with and if signal strength is low.
“The XPander range owes a lot to Apollo’s policy of listening to its customers,” says Paul Smith, Apollo’s Head of Marketing. “Apollo is now able to offer a simple solution for both existing and new systems, minimising the need for costly cables and associated disruption.”
