How do I connect and configure an ACS annunciator on the NFW2-100?

To connect an ACS annunciator to the NFW2-100, wire the EIA-485 communication line to TB9 (terminals B+, A+, B-, and A-) and provide 24 VDC non-resettable power (Page 10, 33) [2], [5].

You must then enable the annunciator and its specific addresses in the FACP programming menu (Page 93) [2].

Addressing Annunciator addresses are point-specific on the NFW2-100 (Page 37) [2]:

• Address 1: General System Status and Zones 1-56.
• Address 2: Zones 57-99 and 4 NACs.
• Address 3: SLC Modules 1-64.
• Address 5: SLC Modules 65-99.
• Address 8: SLC Detectors 1-64.
• Address 10: SLC Detectors 65-99.

Configuration Steps

1. Enter the Master Programming Level on the FACP.

2. Navigate to Option Modules and select Annunciators/UDACT (Page 93) [2].

3. Set ACS Installed to "Yes".

4. In the ACS Installed Screen, use the number keys to toggle the specific addresses (1-31) you have physically set on your hardware to "Yes" (Page 93) [2].

5. Ensure the physical DIP switches on the annunciator match the programmed addresses (Page 37) [2].
