Apollo Xpander Diversity Loop Interface Unit - XPA-IN-14050-APO The XPander Diversity Loop Interface Unit can monitor up to 31 XPander devices and report each devices status to an intelligent fire control panel. Brand Information 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. The detectors are multistate in that they report normal, pre-alarm, fire or fault states to the radio base which transmits the information to the interface. The detectors incorporate drift compensation and report any compensation limit occurring. The radio bases and signalling devices are addressable and use a pre-set analogue value to report via the XP95 or Discovery 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. Key Features Connects up to 31 XPander devices to an Apollo Addressable loop Translates radio signals from XPander detectors to the fire control panel Built-in loop isolator Loop-powered Diversity aerial design for improved signal integrity The entire XPander product line has a temporary, four-month supply disruption starting from November 2021 with supply expecting to resume in February 2022.
