The Catalog 177 and 178 mortise type door openers are dependable
long service devices, providing the security and convenience of re­mote control door-lock operation. These units flush mount in place
of the regular door strike plate and are ideal for narrow door stiles.

With the non-reverse acting units, the door remains locked until the
opener is electrically actuated by a remote contact device. For re­verse acting units, the door remains unlocked (with current off).
When energized through a timer or manual switch, the unit keeps
the door locked.

For AC oper ation, use with either an 88-50, 596, or 592 Transformer.
See below table and T ransf ormer Catalog Pages 11-2 and 11-5.

For use in apartments, offices, banks, industrial buildings, schools,
and institutions. Use in door interlocking and control systems with
timed or manual operation.
