Description

The Notifier FST-751 and FST-751R intelligent thermal detectors are used with the PCR-400 Fire Alarm Systems to measure thermal levels caused by fire and report the analog level of the thermal measurement to the control panel. Also, the use of analog information provides significant benefits to the end-user, installer, and service personnel in ways that are not possible with a conventional type system. Since this detector is addressable, it helps firefighters quickly locate a fire in its early stages. Besides, the detectors are intend for use in commercial, industrial, and institutional buildings. Areas with relatively stable temperatures (no rapid changes) can use the FST751R with the rate-of-rise feature for a quicker response.

In general, each FST detector uses one of 159* possible addresses on a control panel SLC loop. It responds to regular polls from the control panel and it reports its type and status, including the analog level of its heat-sensing elements. If it receives a test command from the panel (or a local magnet test), it stimulates its electronics and reports an alarm analog level. It blinks its LEDs when polled and turns the LEDs on when commanded by the panel (detector blink is optional). Furthermore, the FST detectors offer features and performance that represent the latest in thermal detector technology. In addition, the Notifier FST-751 and FST-751R can be use to replace the FDX-551 and FDX-551R detectors, Part No. 417484 and 417485, in existing systems.
