FST-851R NOTIFIER

FST-851R Notifier, Heat Detector Rate Of Rise 135F.

The FST-851R Notifier intelligent plug-in thermal detectors with integral communication have features that surpass conventional detectors. Point ID capability allows each detector’s address to be set with rotary, decimal address switches, providing exact detector locations.

FST-851R Notifier thermal detectors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed temperature (FST-851/A) and rate-of-rise thermal detection (FST-851R/A) in a low-profile package. FST-851H(A) provides fixed high-temperature detection at 190°F/88°C.

These thermal detectors provide effective, intelligent property protection in a variety of applications. FST851(A) Series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).

FlashScan® (U.S. Patent 5,539,389) is a communication protocol developed by Notifier Engineering that greatly enhances the speed of communication between analog intelligent devices and certain Notifier systems.

Intelligent devices communicate in a grouped fashion. If one of the devices within the group has new information, the panel’s CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of earlier designs.

Features

• Sleek, low-profile, stylish design.
• State-of-the-art thermistor technology for the fast response.
• Rate-of-rise model (FST-851R/A), 15°F (8.3°C) per minute.
• Factory preset fixed temperature at 135°F (57°C); high-temperature model fixed at 190°F (88°C).
• Addressable by the device.
• Compatible with FlashScan® and CLIP protocol systems.
• Rotary, decimal addressing (1-99 on CLIP systems, 1-159 on FlashScan systems).

Applications

Use thermal detectors for the protection of property. For further information, go to systemsensor.com for manual I56-407-00, Applications Manual for System Smoke Detectors, which provides detailed information on detector spacing, placement, zoning, wiring, and special applications.

Installation

The FST Series plug-in intelligent thermal detectors use a separate base to simplify installation, service, and maintenance. Installation instructions are shipped with each detector. A special tool allows maintenance personnel to plug in and remove detectors without using a ladder Mount base (all base types) on an electrical backbox which is at least 1.5″ (3.81 cm) deep. For a chart of compatible junction boxes, see DN-60054.
