Fjernenhedsidentifikationssystem |
摘要 |
<p>In a fire, smoke or intruder detection system including a master unit (2) and satellite units (1) with remote sensors, the satellite units (1) send alarm transmissions to the master unit over a radio frequency channel. In order to register satellite units with the master unit each satellite unit is provided with a unique identification code and, after suitable triggering, sends a signal including this code to the master unit over a line-of-sight communications channel. The master unit registers satellite unit identification codes received on the line-of-sight channel and disregards radio frequency transmissions if they include unregistered satellite unit identification codes. <IMAGE></p> |
