One standard 2x4 cut to 14.5” (36.83 cm)
l
Digital Clock Model: one square shallow 4x (10.16 cm x 10.16 cm) junction box
l
Digital Timer Model: two square shallow 4x4 (10.16 cm x 10.16 cm) junction boxes

Four drywall anchors
Install a Flush-mount Digital Clock/Timer
Complete the steps below to flush-mount a digital clock/timer.
1. Cut a hole in the wall surface that is 5.4” (13.71 cm) x 14.4” (36.57 cm) between two studs.
Figure 1: Flush-mount Wall Opening Dimensions
NOTE: Clearance within the wall should be at least 2.5” (6.35 cm) deep to allow for the clock assembly.
2. Secure a standard 2x4 cut to 14.5” (36.83 cm) between the two studs located 0.5” (1.27 cm) above the top of the bottom of the
opening and 2.4” (6.0 cm) from the front of the opening.

Code Blue Timer Input: wire to designated code blue system and timer control switch.
Elapsed Timer Input: wire to timer control switch.
11. Place the clock assembly into the wall opening. The clock assembly is to be flush on the wall and the junction box holes must
line up with the clock assembly slots.
Figure 8: Flush Mounting
Figure 9: Clock Assembly Slots
NOTE: If the clock assembly does not line up with the junction box it is possible to increase the opening up to 0.3” (14.7” total)
on either side as well as 0.2” (5.6” total) on the top or bottom. If these adjustments still do not allow the clock assembly
to be mounted to the junction box correctly, it is required to remount the junction box.
12. Install drywall anchors (not supplied) to align with the four fastening holes located on the front of the clock assembly.
13. Mount the clock assembly to the junction box(es), using the screws supplied with the junction box and the #8 washers
(supplied).
14. Reconnect the circuit board power cord connector and the timer input connector that was disconnected in step 6.
15. Refasten the circuit board using the four screws previously removed.
16. Peel off the protective checker board film from the two strips of tape and attach the face plate to the clock assembly.
