7. SECURE MAGNET TO MOUNTING PLATE
Install the electromagnet to the mounting plate by tightening the captured 1/4-20 x 2" socket head cap screws with a
3/16" hex key. Firmly tighten the screws. Pass wiring through hole in top of magnet and through access hole on circuit
board side of magnet as shown below. If the unit has DSM and/or SEC and/or BOCA there will be up to two switch
contacts with plug-in leads mounted on the access cover. Pass these leads through the access hole on circuit board
side of magnet. Secure access cover. Drive in anti-tamper plugs using a rubber mallet.
NOTE: Double units with SEC2 or BOCA2: Do not switch covers between units. The wiring on each cover is
different and doing so will cause improper operation.
6. SECURE MOUNTING PLATE
Using the Mounting Plate as a template, drill the
four remaining mounting holes.
Tighten two 10-24 self tapping pan head screws
If using #10 self-tapping, flat-head screws drill
5/32" dia. holes and drive four screws tight.
If using #10-24 flat head machine screws, drill and
tap for #10-24 threads and tighten four screws.
CAUTION: It is critical that the screws used secure
the mounting plate to the structure of the frame.
