2V1LOCK – is a useful device allowing connection of two driving voltages to a single electric lock without danger of damage if both voltages are applied at the same time.
E.g. if an existing door-phone system needs to be upgraded with an access controller, this device will connect the driving voltages from the door-phone system and the access controller to the electric door strike. Any one of the two driving voltages will open the door, but no collision will occur if they are present at the same time.
Features
- Use either of two voltages to drive door strike solenoid
- Use one 12V voltage and one 24V voltage to drive 24V solenoid
- Drive inverse (no voltage to open) lock with normal voltage
