Honeywell FCM‑1 Central Processing Board

Honeywell FCM‑1 (NOTIFIER) Central Processing Board

 Product Description

FCM‑1 is the core CPU board unit of the Honeywell NOTIFIER ONYX series NFS2‑640 intelligent fire alarm controller. It integrates an onboard power supply and is a core computing control component for the alarm host, used in standalone or networked fire alarm systems. It has 1 onboard SLC signal loop, which can be expanded to 2, responsible for detector and module signal acquisition, fire alarm logic operation, linkage output, event recording, host communication management; supports on-site programming configuration and can be used in conjunction with display keyboard components.

Product Performance

1. It collects fire alarm, fault and supervision signals, and performs logical operations and output control for fire protection linkage.
2. It has a large capacity for event log recording, with no data loss in case of power failure, facilitating fault traceability.
3. The circuit has short circuit, open circuit and grounding fault detection and alarm reporting.
4. It supports single machine operation, and by adding NCM network card, it can achieve multi-host networking and networking.
5. It supports local/remote programming of the upper computer software and parameter download/upload.
6. It integrates battery charging and discharging management and has battery fault monitoring and protection.
7. The hardware versions CPU2-640 and CPU2-640E can be interchanged, but the firmware version needs to be compatible with the entire machine.
