The Genesis Masthead is weather proof to IP66 and forms the heart of a Genesis Wireless system. Its purpose is to receive alarm data from the PIR's and pass it to a control unit via an RS232 link. 
A Masthead can transmit data as well as receive it, which means it will transmit back to a Walk Test Instrument to show all received information as well as the signal strength at the masthead. 
In this way the installer knows that the detector is working correctly and also that it is being received by the system. In addition, it can perform as a repeater for systems that require greater transmission operating distances. Up to seven repeaters can be used in any one system to provide transmission range of several kilometres. 
Finally, the Masthead can be programmed with individual names for each unit number which are transmitted to the walk test instrument or pager to aid location of the detector. An optional aerial (AE434) may be used instead of the supplied aerial for improved reception.
