Notifier FSI-851 Ionization Smoke Detector

NOTE: Due to low level customer need and their radioactive content, NOTIFIER will be discontinuing addressable ionization smoke detectors as of July 1, 2015. The SUGGESTED ALTERNATIVES to ionization technology are photoelectric, multi-criteria or aspiration smoke detectors. All provide comparable or improved performance to ionizations and are more environmentally friendly: — FSP-851 FlashScan/CLIP Photoelectric Detector — FSP-851T FlashScan/CLIP Photo/Thermal Detector — FAPT-851 FlashScan/CLIP Acclimate™ Intelligent Photo Thermal Detector — FSC-851 FlashScan IntelliQuad Intelligent Addressable Multicriteria Fire Detector  — FSL-751 FlashScan VIEW Detector — FSA-8000 Intelligent FAAST Detector Notifier 851 Series Intelligent plug-in detectors are compatible for use with all Notifier Intelligent Fire Alarm Control Panels. COMPATIBLE INTELLIGENT BASES: — B210LP Standard U.S. flanged low-profile mounting base. — B710LP Standard replacement flanged low-profile mounting base. — B501 Standard European flangeless mounting base. — B200S Intelligent, programmable sounder base — B200SR Intelligent sounder base - Replaces B501BH series bases in retrofit applications. — B224RB Plug-in System Sensor relay base. — B224BI Plug-in System Sensor isolator detector base. NOTE: All base types require an electrical backbox which is at least 1.5" (3.81 cm) deep.
