MRC MAINS RATED RELAY MODULE
The MRC is a Single Input / Output Module, which is fully compatible with Hochiki’s ESP analogue addressable protocol.
It has been designed to provide a single mains rated relay output (via the flying leads), for the control of such devices as dampers, extractors or plant and equipment shutdown.
A general purpose auxiliary input is provided which is fully monitored for short and open circuit, the monitoring can be disabled with bit 8 on the DIL switch.
The MRC utilises simple DIL switches for reliable addressing and it is supplied as an OEM version (as illustrated above).
