Hidden Power Supply Mount
You can hide the power supply portion of the Master above a dropped ceiling, under a raised
floor or behind a wall, up to 8 feet away from the display unit. This allows you to hide the
cables and gives a more pleasing look to your Master. To mount the Master this way, you
must purchase the 8-foot connection cable
To hide the power supply
Place the Master on its back with the display unit facing up and the keypad to the right
Remove the two screws from just above the display unit
Lift the display unit up and away from you. Note that two rivets at the bottom of the
cover prevent you from lifting it straight up
Unplug the ribbon power cable from the back of the display unit
Set the display unit aside
Detach the display unit from the power supply cover by removing the 4 screws on the
back of the display unit (IMPORTANT: These screws are the correct length so they do
not interfere with the circuit board inside the display unit. Using any other screws voids
any warranty)
Unplug the ribbon cable from the power supply board
Remove a knockout in the power supply and pass the 8-foot connection cable through it
using proper strain relief hardware. When properly installed, the cable will face away from
the transformer
