The Masthead Relay Unit provides a simple interface for virtually any kind of alarm input because it has volt free relay contacts. It is weather proof to IP66 and so it can be fitted externally with a dome camera and connected directly into the alarm pre-sets.
This unit provides either 4 alarm outputs with corresponding tamper outputs or eight alarm outputs without tampers. DIL switches set the different modes as well as the unit code groups.
Expansion cards are available to increase the number of alarm outputs. (LGREM4X4)
There is no limit to the number of LGMRU4x4 units that can be used on any one system.
The LGMRU4x4 will also re-transmit any incoming data which can then be received by a Walk Test Indicator and it can also act as a repeater.
