FM-approved, the Assured Automation FireChek thermal shutoff with a resettable memory shape alloy automatically shuts down a pneumatic control system when a nearby fire occurs or the ambient temperature reaches 135°F, 150°F or 165°F; it immediately closes the air supply line to prevent air from feeding the fire and simultaneously vents the spring return actuator to allow the return to fail-safe. Compatible with most pneumatic actuators, the shutoff is used in batch and continuous processes.
