Installing the ECS-50W ECS Device Installation
4.4.1 ECS-50W Board Layout
Figure 4.19 shows the location of terminals, DIP switches, and expander connection, used in the installation of the ECS-50W.
4.4.2 Mounting the ECS-50W
The ECS-50W is equipped with a separate enclosure. Refer to Section when selecting a mounting location for the ECS-50W.
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” plywood to the concrete surface and then attach the cabinet to the plywood. Also mount any other modules to
the plywood.
The cabinet can be surface or flush-mounted. If you will be 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 26.5” H x 4.125” D (40.6cm W x 67.3cm H x 10.5cm D).
Follow these steps to properly mount the cabinet.
1. Mark and pre-drill hole in the wall for the center top keyhole mounting bolts using the dimensions below.
2. Install center top fastener in the wall with the screw head protruding.
3. Place backbox over the top screw, level and secure.
4. Mark and drill the lower mounting holes.
