Figure 2-75 shows an NFPA Style Z NAC with notification appliances connected to an
M500CH module.
Connect the NAC as follows:
1. Connect the SLC to M500CH terminals 1 (–) and 2 (+).
2. Connect 24 VDC power from MPS-400 TB2 to M500CH terminals 3 and 4.
3. Set the M500CH rotary switches to the required loop address. (The M500CH takes
one module address on the SLC.) For instructions on setting rotary switches, see
Figure 2-67 on page 2-49.
