Delta Series Audio Controllers
Installation into the Wall Cavity
1. After wiring is complete, simply push the wiring back into the wall cavity and make sure there is
enough room for the Matrix keypad to comfortably fit into the opening.
2. Once the keypad had been set into the wall opening, line up the mounting holes with the receiving
threaded holes in the wall plate (or electrical box).
3. Begin threading the top and bottom screws by hand and finish with a screwdriver.
4. Once the installation is complete, snap on the cosmetic trim panel and install any additional
remaining keypads.
5. Once the keypad wiring is connected and correctly plugged in, install the keypad into the wall cavity
with the supplied screws. Make sure there is no binding of the wiring and that the keypad fits
without forcing it into the opening.
6. After the keypad is secure, proceed with the installation of the decorative trim panel (FIG. 14).
Do not force the keypad up against wiring or other obstructions if it cannot fit flush to
the mounting holes because damage can occur to the circuit board of the keypad.
