INSTALLATION & WIRING:
The GT-OP2 and GT-OP3 Postal Lock Panels are for use with a GT Series Multi-Tenant Entry Security intercom system
and allow a postal lock device to be mounted alongside the entry panel. The lock device is available from the post office
and mounts behind the panel, accessible via the keyhole opening. The timer relay can be adjusted to provide a contact
closure from 5 to 20 seconds. NOTE: The GT-OP3 has an available position for an additional module. This opening can
be filled by any type of module, but must be purchased separately.

* The green and white wires bypass
the timer circuit and go directly to the
switch. Use this connection when
going to a 3rd party timer or when the
timer circuit is not needed. The
orange, black, yellow, blue, and red
wires would not be used if you
connect to the green / white bypass.
IMPORTANT: If the Green and White wires are not used, cut wires to avoid a possible malfunction.
