HCP-WM-SCI is a weatherproof Manual Call Point with integral short-circuit isolator, which is fully compatible with Hochiki’s ESP analogue addressable protocol.
The unit incorporates a bi-coloured LED, which can be selected as pulsing/non-pulsing*1 for communications polling and is continuously lit when the HCP-W/M(SCI) is operated – in these two states the LED will show red. The LED will show amber when a short-circuit is present but will switch to red if the unit is activated. The unit operates by pressing the EN54 compliant non-frangible (plastic) element and produces a high level ESP interrupt. A built in test function initiated by the control panel ensures the integrity of the device at all times and the device can be tested by insertion of a test key in the underside of the unit. Two terminal blocks are provided for easy connection to the loop wiring.
The unit is addressed using the TCH-B200 Hand Held Programmer for quick and reliable addressing. An optional glass element is also available.
