Installing the ECS-NVCM ECS Device Installation
4.3.2 Installing the ECS-NVCM
1. Remove AC power from the FACP.
2. Open the cabinet.
3. Align the ECS-NVCM over the mounting studs below the FACP board and secure with six supplied nuts/lockwashers. Refer to the
figures below for mounting locations.
4.3.3 Installing and Connecting the ECS-EMG to the ECS-SW24
The ECS-SW24 adds 24 switches to the IFP-300ECS and IFP-2100ECS controls for a total of 40, with the 16 non-ECS switches on the ECS-EMG.
Follow these steps to install and connect the ECS-SW24:
1. Open Cabinet door and dead front panel.
2. Remove AC power from the main control panel.
3. Disconnect the backup batteries.
4. Install the ECS-SW24 on the six mounting studs located on the inside of the dead front panel. See Figure 4.14 for IFP-300ECS or
Figure 4.15 for IFP-2100ECS.
5. For the IFP-300ECS, connect one end of the wiring harness (P/N 130398 supplied) to the ECS-EMG and the other end to the ECS-
SW24 as shown in Figure 4.14.
6. For the IFP-2100ECS, connect one end of the wiring harness (PN 130398 supplied) to the ECS-EMG and the other end to the P4
connector on the ECS-NVCM. If two ECS-SW24 modules are used, connect one ECS-SW24 to the other ECS-SW24. See Figure 4.15.
7. Secure the switch expander(s) to the dead front panel using the supplied six 0.25” hex nuts.
8. Restore AC power.
9. Reconnect backup batteries.
