FSP-851(A) Series

Intelligent Plug-In Photoelectric

Smoke Detectors with FlashScan®

Intelligent/Addressable Devices

DN-6935:D • H-202

General

Notifier FSP-851(A) Series intelligent plug-in smoke detectors

with integral communication provide features that surpass con-

ventional detectors. Detector se

nsitivity can be programmed in

the control panel software. Sensitivity is continuously monitored

and reported to the panel. Point ID capability allows each detec-

tor’s address to be set with rotary, decimal address switches,

pro

viding exact detector location for selective maintenance

when chamber contamination reaches an unacceptable level.

The FSP-851(A) 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(A). The FSP-851R(A) is a remote test capable detector for

use with DNR(A)/DNRW duct detector housings. FSP-851(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 proto-

col developed by Notifier that greatly increases the speed of

comm

unication between analog intelligent devices. Intelligent

devices communicate in a grouped fashion. If one of the devices

in 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.

• Compatible with FlashScan® and CLIP protocol systems.

• Rotary, decimal addressing (1-99 on CLIP systems, 1-159 on

Flash

Scan systems).

• Optional remote, single-gang LED accessory.

• Dual LED design provides 360° viewing angle.

• Visible bi-color LEDs blink green every time the detector is

dressed, and illuminate steady red on alarm (FlashScan

systems only).

• Remote test feature from the panel.

• Walk test with address display (an address on 121 will blink

the detector LED:

12-[pause]-1(FlashScan systems only).

• Built-in functional test switch a

ctivated by external magnet.

• Built-in tamper-resistan

t feature.

• Sealed against back pressure.

• Constructed of off-white fire-resistant plastic, designed to

comme

rcial standards, and offers an attractive appearance.

• 94-5V plastic flammability rating.

• SEMS screws for wiring of the separate base.

• Optional relay, isolator, and sounder bases.

DETECTOR SPACING AND APPLICATIONS

FSP-851(A) in B210LP(A) Base

B210-2951.jpg

Notifier recommends spacing detectors in compliance with

NFPA 72. In low airflow applications with smooth ceiling, space

detectors 30 feet (9.144m) for ceiling heights 10 feet (3.148m)

and higher. For specific information regarding detector spacing,

placement, and special applications refer to NFPA 72. System

Smoke Detector Application Guide, document A05-1003, is

available at systemsensor.com

ELECTRICAL SPECIFICATIONS

Voltage Range: 15-32 volts DC peak.

Standby Current (max. avg.): 30

0μA @ 24VDC (one commu-

nication every five seconds with LED enabled).

LED Current (max.): 6

.5mA @ 24 VDC (“ON”).

Installation

FSP-851(A) 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 (all base types) on an electrical backbox which is at

ast 1.5" (3.81 cm) deep. For a chart of compatible junction

boxes, see DN-60054.

NOTE: 1) Because of 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 the ISO-X(A) installation
