ECS Device Installation
4.6.1 ECS-125W Board Layout
Figure 4.37 shows the location of terminals, DIP switches, and expander connections used in the installation of the ECS-125W.
4.6.2 Mounting the ECS-125W
The ECS-125W is equipped with a separate enclosure. Refer to Section 3.1 when selecting a mounting location for the ECS-125W.
The panel should be accessible to main drop wiring runs. It should be mounted as close to the center of the building as possible and located
within a secured area, but should be accessible for testing and service.
Mount the control panel cabinet so it is firmly secured to the wall surface. When mounting on concrete, especially when moisture is
expected, attach a piece of ¾-inch plywood to the concrete surface and then attach the cabinet to the plywood. Also, mount any other mod-
ules to the plywood.
The cabinet can be surface or flush-mounted. For flush-mounting the cabinet, the hole for the enclosure should be 14.5" W x 24.75" H x
3.44" D (36.8cm W x 62.9cm H x 8.7cm D). Do not flush-mount in a wall designated as a fire break. The outside dimensions of the cabinet
are 16" W x 26.25" H x 4.125" D (40.6cm W x 66.7cm H x 10.5cm D).
Follow these steps to properly mount the cabinet.
