Installing the keypad
The SC Series keypads each use the same plastic housing and
are designed to easily install on any 4 square box, 3-gang switch
box, 695 and 696 backbox, or flat surface. The Keypad Mounting
Template below shows the mounting hole location and reference
card location on the keypad base. Use this template as a guide for
mounting the keypad.
Wiring the keypad
The keypads are each supplied with one 12-wire Data Bus /Zone
harness. The 741 and 743 also include one 5-wire Output/Reader
harness. The harness connections and color codes are shown in
the keypad harness wiring diagram.
Once all the wire connections are made, mount the keypad using
appropriate size anchors and the enclosed screws.
