Description

Radionics D8127U Poppit Zone Expansion Module Simple Type: Expansion Module The D9127U/T expansion module is a proven multiplex technology combining zone/point supervision with individual device addressing on one pair of wires. The control/communicator uses the D8125 to provide for expansion beyond the standard number of zones up to a total of 240 points of protection. Each D8125 module can fully supervise 120 D9127U/T (Untampered and Tampered) POPITs (Point of Protection Input Transponders). The D9127U/T Modules are used when there is a need to expand the appropriate control/communicators beyond their standard number of on-board initiating zones or points. Download the datasheet (PDF)
