NOTIFIER   FSI-851

Inquiry

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).

FlashScan® (U.S. Patent 5,539,389) is a communication protocol developed by NOTIFIER that greatly improves 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 speed greater than five times that of other protocols.

• 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 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.

FSI-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 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 the ISO-X(A) installation sheet I56-1380 for device limitations between isolator modules and isolator bases.

These listings and approvals apply to the modules specified in this document. In some cases, certain modules or applications may not be listed by certain approval agencies, or listing may be in process. Consult factory for latest listing status.
