2.0 INSTALLATION

2.1 Rough-In (see Fig 2.)

Install the SRMD in a 4 11/16” square electrical box. Run the power and signal 
wiring into the box. Two wires are for the 24 VAC/DC power, and two wires are 
for each of the signal lines from the field sensors to the display. For example, 
the single display version would be 2 wires and the dual display needs 2 wires 
for each of the two displays.

Run the wiring to the 24 VAC/DC source and to the sensors that are to be 
monitored. The power to the sensors is not supplied by the displays.

2.2 Positioning the Front of the Electrical Box

It is very important that the box be set 1/16” to 1/8” below the finish wall so 

that the faceplate will seal against the finished 

wall. 

If possible allow for ad-

justment at the finish stage to set the depth correctly.
