The Hochiki ACB-EW Multisensor is fully waterproof. The ACB-EW is also compatible with Hochiki’s ESP Analogue Addressable Protocol.
The Hochiki ACB-EW has a variable fixed temperature heat element and a Rate of Rise heat element. Both of these elements are controlled from the Control Panel which allows the thermal element, the Rate of Rise element or both elements simultaneously to be active in the making of the fire decision. The sensors LED’s can also be controlled via the Control Panel (pulsing/non-pulsing).
