The Interconnected Heat Detector is for use as a warning device in residential applications. Each detector has a solid state piezo signal to warn and alert the household to the presence of threatening heat.
The Interconnected heat detector is designed to detect heat that results from an actual fire. Heat detector are intended for use as supplements to smoke detector. This unit cannot detect smoke or toxic gases, therefore, do not rely solely on this heat detector to provide a warning of fire.
In the event AC power fails, a 9VDC battery will provide proper detector operation for a minimum of a 24-hour period.
All detectors in a tandem installation must be controlled by the same fuse or circuit breaker. Otherwise tandem units will not operate. Tandem will operate in the event of an AC power failure if battery is connected to the detector.
A heat detector can be connected to a maximum of 12 smoke and 5 other heat detectors, to total not more than 18 interconnected devices. Do not exceed 1125 feet between the first and last detector.
Wire used for interconnecting shall be in accordance with Article 300.3 (b) and Article 210 of the National Electrical Code (NEC) and NFPA 70.
