Model ATJ-ENM is a Multi-Heat Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol
The ATJ-ENM incorporates a Variable Temperature heat element and a Rate Of Rise heat element, both of which are controlled from the Control Panel, allowing either thermal element or both elements simultaneously to be active in making the fire decision
The sensor polling LEDs can also be controlled via the Control Panel (pulsing/non-pulsing)
