Edwards Signaling 283B-PL Heat Detector, Fixed, 135F Temp Rating

The EDWARDS-SIGNALING-283B-PL is a fixed temperature detector. The heat detector is available with a white plastic reversible mounting plate which can be used for flush or surface mounting.

The fixed temperature feature of the 283B-PL has a rated temperature of 135F, which when activated, closes contacts in the sensor and transmits an alarm condition to the fire alarm control panel.

The 283B-PL's fixed temperature element is non-restorable and, when activated, the detector must be replaced. The need for replacement is indicated when the center disk has fallen free from the detector.

The 283B-PL is ideal for environments where rapid fire development can be expected.
