Description

An HVAC (heating, ventilation and air-conditioning) system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system will be distributed throughout the entire building. Smoke detectors designed for use inside the unit are used to sense the presence of smoke passing through the unit.

The smoke detector utilizes photoelectric technology for the detection of smoke. This detection method, when combined with an efficient ducting design, samples air passing through the unit. If sufficient smoke is sensed, an alarm signal is initiated and the ComfortLink controls will shut down the unit. With the unit shut down, the unit will not blow toxic smoke and fire gases throughout the areas served by the duct system.

The return air smoke detector is part number CRSMKDET001D00, which includes a Smoke Sensor and a Smoke Control Module combined with sampling tube, harnesses and hardware. The supply air smoke detector is part number CRSMKSUP001B00, which includes a Smoke Sensor and a Smoke Control Module combined with sampling tube, harnesses and hardware. Part number CRSMKSEN001A00 is a Smoke Sensor only for use as a second (Supply with existing Return, or Return with existing Supply) Air Smoke Detector with sampling tube, harnesses and hardware.

The Control Module can be attached to a Smoke Sensor and installed as an assembled unit, or it can be installed separate from a sensor. One Controller can be used to control up to two detectors (Smoke Sensors).
