Notifier Smoke Detectors with FlashScan

Notifier  FSP-851(A)  Series intelligent  plug-in smoke  detectors with integral communication  provide features that surpass con- ventional 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 detec- tor’s address  to be set with rotary, decimal  address  switches, providing  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 communication 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.

FlashScan 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 addressed, 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 activated by external magnet.
  • Built-in tamper-resistant feature.
  • Sealed against back pressure.
  • Constructed of off-white fire-resistant plastic, designed to commercial standards, and offers an attractive appearance.

DETECTOR SPACING AND APPLICATIONS

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.): 300μA @ 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 least 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
