The Hochiki HCP-E(DPS) Break Glass Manual Call Point is fully compatible with Hochiki’s ESP analogue addressable protocol. Operating the unit can be done by pressing the EN54 compliant non-frangible (plastic) element and it produces a high level ESP interrupt. This allows fast response of the control panel. The integrity of the device is ensured by a built in test function initiated by the control panel. Testing the Hochiki HCP-E(DPS) can be done by inserting a test key at the bottom of the unit.
