Apollo XPander Remote Indicator Module - XPA-IN-14102-APO Designed and manufactured using the latest techniques and surface-mount technology to ensure component count is kept to a minimum whilst maximising reliability, the XPander Remote Indicator Module is used to indicate the activation of an individual device or zone. Brand Information The device is powered by a low-voltage dual supply alkaline battery pack, which has been tested to provide a five-year life at normal conditions (15C to 35C), the condition of which is continually monitored. The system indicates the remaining battery capacity, with a low battery condition being indicated as a fault, allowing 30 days for the battery pack to be changed before unit failure occurs. An additional warning is also given seven days before unit failure occurs. Removal of the remote indicator from the fixing plate will indicate a fault condition. The device is fully compliant with EN 54-25 and incorporates a locking screw to prevent unauthorised removal.
