The model Notifier FST-851R Heat Detector is an intelligent sensor that utilizes a state-of-the-art thermistor sensing circuit for a fast response. As well, these sensors are design to provide open area protection with a 50-foot spacing capability as approve by UL 521. Notifier FST-851R Heat Detector is a rate-of-rise temperature sensor with a 135° F fix temperature alarm. Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available as an optional accessory. Also, is a plug-in thermal detector with integral communication has features that surpass conventional detectors. In addition, It has a point ID capability that allows each detector address to be set with rotary, decimal address switches, providing exact detector locations. It provides effective, intelligent property protection in a variety of applications.
Specifically, require compatible addressable communications to function properly. Connect these sensors to listed-compatible control panels only. Before testing, notify the proper authorities that the system is undergoing maintenance, and will temporarily be out of service. Disable the system to prevent unwanted alarms. All sensors must be test after installation and periodically thereafter. Before cleaning notify the proper authorities that the system is undergoing maintenance, and therefore the system will temporarily be out of service. Disable the loop or system undergoing maintenance to prevent unwanted alarms.
