Hochiki ATJ-ENM Marine Approved Analogue Multi-Heat Sensor (ESP Protocol)

About this product

The Hochiki ATJ-ENM is a marine approved analogue addressable multi-heat sensor fully compatible with Hochiki’s ESP analogue addressable protocol. It combines fixed temperature and rate-of-rise heat elements, which can be user selectable and controlled from the fire alarm control panel, allowing either element or both to be active in making the fire decision. Designed for marine and demanding environments, it features twin 360° LEDs (green when polling and red in fire) and supports panel-controlled pulsing/non-pulsing operation. The device is approved to LPCB EN54 Part 7 and marine approvals including LR and GL.
