GENERAL
NOTIFIER 851 Series intelligent plug-in smoke detectors with inte-
gral communication provide features that surpass conventional
detectors. Detector sensitivity can be programmed in the control
panel software. Sensitivity is continuously monitored and re-
ported to the panel. Point ID capability allows each detector’s
address to be set with decade address switches, providing ex-
act detector locations for selective maintenance when cham-
ber contamination reaches an unacceptable level. The FSP-
851 photoelectric detector’s unique optical sensing chamber
is engineered to sense smoke produced by a wide range of
combustion sources. Dual electronic thermistors add 135°F
(57°C) fixed-temperature thermal sensing on the FSP-851T.
FSP-851 and FSP-851T detectors are compatible with all
NOTIFIER intelligent Fire Alarm Control Panels (FACPs).
FlashScan®
(U.S. Patent 5,539,389)
is a communication pro-
tocol developed by NOTIFIER Engineering that greatly en-
hances the speed of communication between analog intelligent
devices and certain NOTIFIER systems. Intelligent devices com-
municate 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 design.
• Addressable-analog communication.
• Stable communication technique with noise immunity.
• Low standby current.
• Two-wire SLC connection.
• FlashScan® (NFS-640, NFS-3030) and classic CLIP system (AFP-
100, AFP-200, AFP-300, AFP-400, NFS-640, AFP1010, AM2020,
and NFS-3030) compatible.
• Rotary, decimal addressing (1 – 99 on current classic sys-
tems, 1 – 159 on FlashScan® systems).
• Optional remote, single-gang LED accessory (RA400Z).
• Dual LED design provides 360° viewing angle.
• Visible bicolor LEDs blink green every time the detector is
addressed, and illuminate steady red on alarm.
• Remote test feature from the panel.
• Walk test with address display (an address of 121 will blink
the detector LED: 12-
(pause)
-1)
(FlashScan® systems only)
.
• Built-in functional test switch activated by external magnet.
• Built-in tamper-resistant feature.
• Sealed against back pressure.
• Constructed of off-white Bayblend®, designed to commer-
cial standards, and offers an attractive appearance.
• 94-5V plastic flammability rating.
• SEMS screws for wiring of the separate base.
• Optional relay, isolator, or sounder bases.
• Listed to UL 268.
• Backward-compatible.

DETECTOR SPACING and APPLICATIONS:
NOTIFIER recommends spacing detectors in compliance with
NFPA 72. In low airflow applications with smooth ceilings, space
detectors 30 feet (9.144 m) for ceiling heights 10 feet (3.048 m)
and higher. For specific information regarding detector spacing,
placement, and special applications, refer to NFPA 72.
