Model ATJ-EN/SIL is a Heat Sensor, which has been independently assessed and approved for use in a SIL2, low demand safety function with regards to random failure rates.
The ATJ-EN/SIL 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).
