Edwards Signaling 177AF Mortise Type Door Openers

Edwards Signaling 177-AF 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 use in apartments, offices, banks, industrial buildings, schools, and institutions. Use in door interlocking and control systems with timed or manual operation.
