WIDP-HEAT-ROR addressable, wireless rate-of-rise heat detector use a state-of-the-art thermistor sensing circuit for a fast response. The WIDP-HEAT provide rate-of-rise temperature alarm detection at 135°F. The WIDP-HEAT also provides Rate-of-Rise Detection at 15⁰F/min. The WIDP-HEAT communicate with the fire alarm control panel (FACP) through a wireless mesh network to the W-GATE wireless gateway. Intelligent wireless rate of rise (135°) heat detector. Ships with B501W base included. Requires (4) CR-123A batteries (included). SWIFT wireless detectors are intelligent (addressable) detectors which provide secure, reliable communication to the Fire Alarm Control Panel (FACP) across a Class A mesh network. Wireless detectors create an opportunity for applications where it is costly (concrete walls/ceilings, buried wires), obtrusive (surface mount conduit), or possibly dangerous (asbestos) to use traditional wired devices. In addition, both wired and wireless devices can be present on the same FACP providing an integrated wiredwireless solution for increased installation potential.
