The NOTIFIER® FST-951 Series intelligent thermal detectors are
designed for both performance and aesthetics, and are direct
replacements for the FST-851 Series. A new modern, sleek, con-
temporary design and advanced thermal technologies make the
FST-951 Series ideal for both system operation and building design.
The point ID address, set using rotary decimal switches, provide
specific detector locations.
The series includes a 135°F/57°C fixed-temperature, rate-of-rise,
and a 190°F/88°C fixed high-temperature detectors. These thermal
detectors provide effective, intelligent property protection in a variety
of applications. Detectors are available for both FlashScan® and
CLIP applications as designated.

Installation
FST-951 Series plug-in intelligent thermal detectors use a detach-
able base to simplify installation, service and maintenance. Installa-
tion instructions are shipped with each detector.
Mount detector 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.
NOTE: 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 only.
When using relay or sounder bases, consult the ISO-X(A) installation
sheet I56-1380 for device limitations between isolator modules and iso-
lator bases.
Applications
Use thermal detectors for protection of property. For further informa-
tion, refer to I56-6522, Applications Manual for System Smoke
Detectors, which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications.
Construction
These detectors are constructed of fire-resistant plastic. The FST-
951 Series plug-in intelligent thermal detectors are designed to com-
mercial standards and offer an attractive appearance.
Operation
Each FST-951 Series detector uses one of the panel’s addresses
(total limit is panel dependent) on the NOTIFIER Signaling Line Cir-
cuit (SLC). It responds to regular polls from the control panel and
reports its type and the status. If it receives a test command from the
panel (or a local magnet test), it stimulates its electronics and
reports an alarm. It blinks its LEDs when polled and turns the LEDs
on when commanded by the panel. The FST-951 Series offers fea-
tures and performance that represent the latest in thermal detector
technology.
