DIM DUAL CONTACT MODULEModel DIM is a Dual Switch Monitor, which is fully compatible with Hochiki’s ESP analogue addressable system. The unit monitors two independent volt free contacts, which can be selected as either normally open or normally closed, this is achieved by a second DIL switch.

The Dual Switch Monitor has been designed to interface to a variety of inputs such as door contacts, sprinkler flow/ door switches and plant equipment, the DIM has a status LED for indication of communication polling and active input condition.

The DIM utilises simple DIL switches for reliable addressing and it is available in either an OEM version (as illustrated above) or complete with IP65 rated enclosure.
