Kidde® Heat Detector Alarm, Wire-In, Heat Sensor, 4-9/16 in Dia x 1-3/8 in H

• The series 600 heat detector is attractive, durable and features combination rate of rise and fixed temperature operation, heat detectors are available in 135 and 200 deg 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 ft centers
• Fixed temperature reacts to heat by responding to a specific temperature setting
• Series 600 detectors use the same reliable pneumatic rate-ofrise element of former models, but offer added aesthetic appeal
• The pneumatic rate of rise element responds to a rapid rise in temperature, approximately 15 deg F 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
• The fixed temperature element uses a fusible alloy when activated, the external heat collector drops away to provide quick visual confirmation that the element has operated
• The units protrude only 1-3/8 in from the ceiling surface with a junction box mounting, they have pleasing contours and an all white finish that conforms to ceiling aesthetics
