The Hochiki CHQ-MRC/DIN(SCI) is a Single Input/Output Module, which provides a single, mains-rated relay output for the control of such devices as dampers, extractors or plant and equipment shutdown. The monitored input can be used for local power supply fault monitoring or as a general-purpose input. The unit is supplied as a DIN Rail mountable version but is also available as a boxed module. Both models feature an integral short-circuit isolator. The CHQ-MRC/DIN(SCI) utilises simple DIL switches for reliable addressing.

| * Fire alarm control panel compatibility required for these products. ** No fuses are fitted on this device. The relay output circuit must therefore be protected by a suitable over-current protection device to prevent excessive current through the relay contacts. Refer to the relay contact specification in the attached datasheet. | |
