Description
The Notifier FSP-851 is an addressable photoelectric smoke detector for use on Notifier intelligent fire alarm control panels. The detector uses a photoelectric sensing chamber and FlashScan communication, and plugs into a B501 or B210LP detector base, which allows the head to be replaced during maintenance without touching the loop wiring. Each head carries its own address, set either by rotary switches on the detector or by the panel, so a like for like replacement keeps the loop configuration unchanged.
- Plug-in head for maintenance without rewiring
- FlashScan loop communication
- Works with B501 and B210LP bases
- Individual address retained per head

Series Information
The Notifier FSP-851 belongs to the addressable detector family used across the NFS-320 and NFS2-3030 control panels. The family includes photoelectric, thermal and combination detectors plus monitor and control modules, all communicating over the same intelligent loop and sharing the B501 and B210LP base range.
