INSTALLATION

Before installing the keypad, the unit must be partially disassembled 
to access the mounting plate.

The keypad assembly is secured with two tamper-resistant screws. 
Refer to Figure 3 for disassembly details.

  Use the special allen wrench (supplied) to remove the two 

tamper-resistant screws.

  Separate the mounting plate from the keypad assembly.

Install the Electrical Box and Mounting Plate

The keypad is designed to fi t into a single-gang electrical box. The 
box must be deep enough to accomodate the protective plastic 
enclosure. Select a location near the controlled door and choose 
a convenient height for the keypad. Be sure there is good wiring 
accessibility for the unit’s power and the output to the door strike 
or access device.

  Install the electrical box in the wall.

electrical box.

  Screw the mounting plate onto the electrical box (see 

Figure 4).

(see next page), complete the installation 

by securing the keypad to the mounting plate.

  If a lower beeper sound level is required, before installing 

the keypad, remove Jumper JP1 (place the jumper block on 
one pin to save the jumper).

  Hook the keypad assembly onto the mounting plate tab (see 

Figure 5).

  Use the special allen wrench (supplied) to install the two 

tamper-resistant screws.
