The FSI-851(A) intelligent plug-in ion detectors with integral communication has 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 locations for selective maintenance when chamber contamination reaches an unacceptable level.
The FSI-851(A) ionization detector incorporates a unique single- source, dual-chamber design to respond quickly and dependably to a broad range of fires. FSI-851(A) detectors are compatible with ONYX series and CLIP series intelligent Fire Alarm Control Panels (FACPs).
Sleek, low-profile design.
Stable communication technique with noise immunity.
Low standby current.
Two-wire SLC connection.
Compatible with FlashScan and CLIP systems
Rotary, decimal addressing (1-99 on CLIP systems, 1-159 on FlashScan systems).
Optional remote, single-gang LED accessory, RA100Z(A).
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 plastic, designed to commercial 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.
