GS-705N Shear Lock Installation Instruction
Unbalanced air conditioning (stack pressure) can hinder door alignment and must be corrected to help insure positive locking. It
is important to note that the Shear Locks need a regulated 12V DC (or 24VDC) at the lock, and use the highest quality door closer
only. Positive centering door closers are required for all double acting door applicators to help attain consistent dead center
alignment. Also the door latching problems must be corrected prior to installation.

Install the magnet assembly into the door
frame before installation the armature assembly
into the door leaf. The magnet assembly requires
space to run wires, as wall as space for the
recesses portion of the unit. However, make sure
that the position selected for the magnet
assembly leaves enough room on the door to
install the armature assembly.
