Introduction
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. A maximum of 5 interfaces is permitted for each site. For sites that require more than 5
interfaces please contact Apollo.
The radio bases and signalling devices are addressable and use a pre-set analogue value to report via the Apollo
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.
• Up to 5 interfaces per site - contact Apollo for more information
• Up to 31 devices per interface
• Loop-powered interface (Including bi-directional Short Circuit Isolator)
• Wireless addresses seen by control panel as normal addresses
• Radio base with wireless circuitry and battery compartment
• Optical chamber designed to inhibit dirt penetration and thus reduce false alarms
• Automatic drift compensation with DirtAlert™ warning
• Detection algorithms for transient rejection
• FasTest™ reduces time taken to test detectors
• Remote test facility
• 5-year battery life (It is recommended that the battery is changed in year 4 of maintenance)
• Alkaline Panasonic® Powerline or Alkaline Varta® Industrial are the recommended battery types to use
• Modern styling
