General
Notifier FSP-851(A) 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 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) fixedtemperature thermal sensing on the FSP-851T(A). The FSP851R(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
protocol 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.
