General
Notifier FST-851 Series intelligent plug-in thermal detectors
with integral communication has features that surpass conven-
tional detectors. Point ID capability allows each detector’s
address to be set with decade address switches, providing
exact detector locations. FST-851 Series thermal detectors
use an innovative thermistor sensing circuit to produce 135°F/
57°C fixed-temperature (FST-851) and rate-of-rise thermal
detection (FST-851R) in a low-profile package. FST-851H pro-
vides fixed high-temperature detection at 190°F/88°C. These
thermal detectors provide effective, intelligent property protec-
tion in a variety of applications. FST-851 Series detectors are
compatible with all Notifier intelligent Fire Alarm Control Pan-
els, except FireWarden series panels. .
FlashScan® (U.S. Patent 5,539,389) is a communication pro-
tocol 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 fast response.
• Rate-of-rise model (FST-851R), 15°F (8.3°C) per minute.
• Factory preset at 135°F (57°C); high-temperature model at
190°F (88°C).
• Addressable by device.
• Compatible with FlashScan® and CLIP protocol systems.
• Direct dial entry of address 01-159 for FlashScan® loops,
01-99 CLIP mode loops.
• Two-wire SLC connection.
• Visible LEDs “blink” every time the unit is addressed.
• 360°-field viewing angle of the visual alarm indicators (two
bi-color LEDs). LEDs blink green in Normal condition and
turn on steady red in Alarm.
• Integral communications and built-in device-type identifica-
tion.
• Remote test feature from the panel.
• Built-in functional test switch activated by external magnet.
• Walk test with address display (an address of 121 will blink
the detector LED 12-(pause)-1).
• Low standby current.
• Backward-compatible.
• Built-in tamper-resistant feature.
• Designed for direct-surface or electrical-box mounting.
• Sealed against back pressure.
• Plugs into separate base for ease of installation and main-
tenance. Separate base allows interchange of photoelec-
tric, ionization and thermal sensors.
• SEMS screws for wiring of the separate base.
• Constructed of off-white Bayblend®, designed to commer-
cial standards, and offers an attractive appearance.
• 94-5V plastic flammability rating.
• Remote LED output connection to optional RA400Z remote
LED annunciator.
• Optional sounder, relay, and isolator bases.
• Optional recessed (RMK400) or surface (SMK400E) base
mounting kits.

Installation
The FST Series plug-in intelligent thermal detector uses a sep-
arate base to simplify installation, service, and maintenance.
Installation instructions are shipped with each detector.
Mount base (all base types) on an electrical backbox which is
at least 1.5" (3.81 cm) deep. Suitable boxes include:
• 4.0" (10.16 cm) square box.
• 3.5" (8.89 cm) or 4.0" (10.16 cm) octagonal box.
• Single-gang box (except relay or isolator base).
• With B501BH-2 or B501BHT-2 base, use a 4.0" (10.16 cm)
square box.
• With B224RB or B224BI base, use a 3.5" (8.89 cm) or 4.0"
(10.16 cm) octagonal box, or a 4.0" (10.16 cm) square box.
NOTE: 1) Because of the inherent supervision provided by the
SLC loop, end-of-line resistors are not required. Wiring “T-taps” or
branches are permitted for Style 4 (Class “B”) wiring. 2) When
using relay or sounder bases, consult data sheet DN-2243 (ISO-X)
for device limitations between isolator modules and isolator bases.
