Determine switch mounting location based on wall or construction,
applicable standards and intended use.
Punch out holes in the jamb box in the areas provided. Use caution and do
not damage any electronics present in the box.
Drill holes in mounting surface using the mounting box as the template. In
hardwired installations, drill a wiring access hole.
Insert the appropriate fastener through the box and into the mounting
surface and tighten securely. Make sure the box is mounted flat, not
twisted.
In hardwired installations, wire the jamb switch to the door controller
using spade terminals to connect to the NO and COMMON contacts. A
knockout area is provided for routing switch wires into the box. For radio-
controlled installations, wire the jamb switch to the transmitter using the
NO and COMMON contacts.
Use the enclosed wrench to tighten the #6-32 screws into the jamb box
(as shown in the top drawing on right).
Test for proper operation.
