Chemetronics 622
Heat Detector, Gray Ring, Dual Circuit, Rate-of-Rise and Fixed Temperature, 200°F (94°C)
Material Obsolete
Description
The Series 600 Heat Detector is attractive, durable and features combination rate-of-rise and fixed temperature operation. Heat detectors are available in 135°F and 200°F temperature ratings. Rate-of-rise detects heat by quickly responding to a rapid temperature increase. Rate-of-rise units have a wide spacing allowance of 50-foot centers. Fixed temperature reacts to heat by responding to a specific temperature setting.
Series 600 Detectors use the same reliable pneumatic rate-of-rise element of former models, but offer added aesthetic appeal. The pneumatic rate-of-rise element responds to a rapid rise in temperature, approximately 15°F. (8°C) per minute, by expansion of air within the sealed chamber faster than it can escape through a calibrated vent. The resultant increase in pressure depresses the diaphragm, causing the electrical contact to close the circuit.
