The 170 Series mortise type door openers are 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.
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 operation, use with either an 88-50, 596, or 592 Transformer.
Continuous Duty Operation
The 177-RG5 and 178-RG5 are suitable for continuous duty operation. However, when operated from 24V AC, they must be connected through the SR-1 Silencing Assembly. They may also be operated directly from 24V DC
