After several months and some delays, I finally completed another fire alarm panel project!
Here is the Notifier NFS-640, part of the 1st generation of ONYX series panels.
This panel contains a mix of new and used parts. It has 2 bays, 2 CRM-4RK modules, and an ACM-24AT (with an expander). All of the dress panels and backbox are new; I pulled the door from an AFP-400 panel.
The top bay contains the CPU on a CHS-M2 chassis. The CPU has an internal power supply, 4 built-in NACs, relays, EIA-485 (annunciators/AMG-1), EIA-232 (PC/printer), and one SLC loop. The CHS-M2 supports up to 2 panel circuit modules and various other cards. An LEM-320 SLC loop expander and an NCM-W network card are attached to the CPU board. The dress panel for the top bay is the DP-DISP.
The middle bay contains the ACM-24AT. The annunciator is attached to an ADP-4B dress panel. Inside is a fully-loaded CHS-6 with a variety of XP modules, including: XP5-M monitor, XP5-C control/relay, XP6-MA zone interface, XP6-R relay, XP10-M monitor, and XP6-C control. All of these modules communicate to the CPU via the SLC. Altogether, this provides the system with 21 monitor points, 11 NACs, and 6 relays.
The bottom bay is just space for batteries. It has the BP-4 dress panel.
I configured this NFS-640 to be a fully-contained demo setup. Each of the relay modules can trip the monitor points on the system. The ACM-24AT displays the status of monitor points and provides toggle controls for NACs/relays.
The NFS-640 is one of my favorite Notifier panels (after the NFS-3030). I prefer the 1st generation ONYX panels over 2nd gen, mostly because the older ONYX panels still support panel circuit modules. The NFS-640 inherits many features from older AFP panels (i.e. AFP-400): networking, voice/telephone features (AMG-1/FFT-7), and suppression/release. It adds to these features with: the FlashScan protocol, strobe synchronization (System Sensor), and an optional larger LCD screen (NCA).
In the future, I plan to network this panel to all of my other compatible Notifier panels. Another excellent addition to my collection of fire alarm panels!
