Answer:
The 851 Series connects to Honeywell Notifier intelligent FACPs (including NFS-320, NFS-640, NFS2-640, and NFS-3030/NFS2-3030) via FlashScan or CLIP protocols. It mounts to B210LP(A)/B710LP flanged bases, B501(A) flangeless bases, B200S(A) sounder bases, B224RB(A) relay bases, and B224BI(A) isolator bases.
The Honeywell Notifier 851 Series intelligent plug-in thermal detector is designed for seamless integration across Notifier addressable loop architecture:
- Fire Alarm Control Panels (FACPs): Fully compatible with all Notifier intelligent panels communicating via FlashScan high-speed protocol or classic CLIP protocol, including the NFS-320, NFS-320C, NFS-640, NFS2-640, NFS-3030, and NFS2-3030 systems.
- Mounting Bases (Ordered Separately): The detector head requires a compatible plug-in base. Supported options include:
- B210LP(A) / B710LP: Standard 6.1-inch flanged mounting base.
- B501(A): Compact 4.1-inch flangeless European-style base.
- B200S(A) / B200SR(A): Intelligent addressable sounder bases.
- B224RB(A): Form-C dry contact auxiliary relay base.
- B224BI(A): Fault isolator base to protect the SLC from loop shorts.
- Accessories: Supports remote alarm indication through connection terminals for the optional RA100Z / RA400Z remote LED annunciator.
- Wiring Supervision: Installs on a supervised two-wire SLC loop. Per installation instructions, wiring must be severed at each terminal run to ensure connection supervision; do not loop uncut wire under terminals.
