Mounting to a Wall 

After deciding where to mount the clock, make two marks 12" apart 

and horizontal.  

Note: If mounting near a ceiling, make sure the holes 

are at least 2 1/4" away from the ceiling.  Also, provide at least 16" of 

side clearance on one side in order to remove the front panel. 

 

Installation Steps 

1.

 

Drill a 5/16" hole at each mark 

2.

 

Insert a wall anchor and tap it flush to the wall with the hammer. 

3.

 

Insert a screw into each wall anchor leaving 1/4" exposed. 

4.

 

Line up the two keyholes on the back of the case and slip over the 
two screws and tighten securely. ( The lower mounting holes can 

be marked at this point, the case removed, holes drilled and wall 
anchors installed if so desired) 

Mounting to a Single Gang Box 

Two mounting holes are located in the center of the case 2 1/4" apart 

for mounting to a single gang wall box. A 7/8" hole is located between 
the mounting holes that will accommodate conduit, if desired. 

 

Note: If mounting near a ceiling, make sure the holes are at least 2- 

1/4" away from the ceiling.  Also, provide at least 16" of side clearance 
on one side in order to remove the front panel. 

 
Line the two holes in the case up to the single gang box and insert 

proper screws for the single gang box and tighten securely.

Double Mount - Ceiling 

Requires optional mounting kit (SAM0626) 

 

Double-Mounting - Ceiling 

Note: Make sure you have at least 16" of side clearance on one side in 
order to remove the front panel assembly. 

 

1.

 

Place the two clock enclosures back to back and secure by inserting 
a #10 screw through the four mounting holes using lock washers 

and nuts supplied with the mounting kit. 

2.

 

Note: If the ATDDC4 clocks will be mounted too near a wall on one 

side to secure the end caps, install the "wall side" end caps now.

 

3.

 

Remove the center vent cap from the top of each ATDDC4 clock. 

4.

 

Line the two posts from the mounting plate up with the vent holes 
of the ATDDC4 clocks. Insert the chase nipples through the vent 

holes and secure to the mounting plate with a 15/16" wrench.
