The Notifier FSP-951 is an intelligent photoelectric smoke detector in a low-profile form factor, combining advanced detection technology with dual-protocol FlashScan and CLIP addressable communication. It is the enhanced sibling to the FSP-851, sharing the same low-profile footprint while offering additional sensitivity options and compatibility with the full range of Notifier addressable fire alarm panels.
Designed for commercial and light industrial environments, the FSP-951 uses a photoelectric sensing chamber with drift compensation circuitry to maintain consistent sensitivity over the detector’s service life — reducing false alarms caused by dust accumulation while ensuring genuine smoke events trigger a reliable alarm. Its compatibility with standard Notifier bases eliminates the need for new base hardware when performing upgrades or replacements.
