ST-ACW-SCR

Model ST-ACW-SCR 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

for communications polling and is continuously lit when the ST-ACW-SCR 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.
