Intelligent Plug-in Photoelectric

Smoke Detectors with FlashScan®

Section: Intelligent/Addressable Devices

GENERAL

NOTIFIER 851 Series intelligent plug-in smoke detectors with inte­gral communication provide features that surpass conventional
detectors. Detector sensitivity can be programmed in the control
panel software. Sensitivity is continuously monitored and re­ported to the panel. Point ID capability allows each detector’s
address to be set with decade address switches, providing ex­act detector locations for selective maintenance when cham­ber 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®
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

INSTALLATION

FSP-851 plug-in detectors use a separate base to simplify in­stallation, service, and maintenance. A special tool allows main­tenance personnel to plug in and remove detectors without us­ing a ladder.

Mount base on an electrical backbox which is at least 1.5" (3.81
cm) deep. Suitable mounting base 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

•

With B501BH or B501BHT base,

square box.

•

With B224RB or B224BI base,

nal box, or a 4.0" (10.16 cm) octagonal or square box.

NOTES: 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.
