NOTIFIER FSP-851 Smoke Detector

The NOTIFIER FSP-851 is an intelligent addressable photoelectric smoke detector designed for compatible NOTIFIER fire alarm control systems. Its optical sensing chamber is engineered to detect smoke from a broad range of combustion sources, while analog communication allows the control panel to monitor smoke levels and detector status. The detector supports programmable sensitivity from 0.5% to 2.35% per foot obscuration and provides continuous sensitivity monitoring for maintenance alerts. Its low-profile design uses a two-wire SLC connection and supports FlashScan and CLIP communication protocols. Rotary decimal addressing provides precise device identification, while dual LEDs offer 360-degree visibility. The detector includes a built-in test function and tamper-resistant design. A compatible detector base is required for installation.
