Hochiki ESP Intelligent Marine Approved Multisensor Optical/Heat (Ivory) (ACC-ENM)

The Hochiki ACC-ENM is a marine-approved analogue addressable multi-sensor in an ivory case, combining a heat element with a High Performance photoelectric smoke chamber. It is fully compatible with Hochiki's ESP analogue addressable protocol.

It has three modes, set from the control panel, so the optical element, the heat element or both can be used to make the fire decision. The smoke chamber is easy to remove or replace for maintenance. Hochiki's marine range is based on its ESP and CDX ranges and is approved for marine use by DNV under the EU Marine Equipment Directive (MED), for ships, oil platforms, offshore installations and wind farms.
