When FireChek® Senses excessive heat from a nearby fire,it immediately vents the pneumatic actuator and closes the actuator air supply line. FireChek® triggers quickly,securing pneumatically operated process line valves. Because FireChek® responds to heat,not flame,it offers dramatically improved protection compared with conventional plastic tubing burn-through.It shuts off the air supply line to prevent plant air from feeding oxygen to a fire.

• Rapidly responds to temperature rise, NOT flames
• Vents actuator air pressure
• Closes actuator air supply line
• Needs no power source, self activates
• Compatible with ALL pneumatic actuators
• No contact with process fluids
• Easy to test and reset
• Reliable, intrinsic triggering
• Easily retrofit, installs in minutes

Shape Memory Alloy Actuator:
The shape memory element senses the ambient temperature and, through a phase induction change, rapidly produces the force and motion to operate FireChek®. The element is 100% reliable because the shape memory effect is intrinsic to the alloy. Shape memory alloys have performed successfully for years in military, industrial, and consumer product applications.

If FireChek® senses temperatures above the shape memory alloy's actuation temperature, the shape memory element simultaneously vents pneumatic actuator air pressure and closes upstream supply pressure. FireChekÕs® manual reset allows routine performance testing for safety maintenance programs. A hot-air gun will quickly actuate FireChek®. After cooling briefly, the FireChek® can easily be reset without the use of tools, for continued protection.

FireChek® installs easily between the pneumatic supply and spring return actuator via two female threaded connections.
