We have developed this product for WISECOMM video door phone (Model #VDP1300
and VDP1500). Before installation, figure out which side (left or right) the door hinges
are installed to and then decide the direction of the door release lock (refer to Fig. 1 or
2).
Turn two screws counter-clockwise to
open the door release lock (Fig. 3).
Install the door release lock on the door and door strike on the doorframe
respectively. They must be installed at a distance of 5 mm between them for
proper operation (Fig. 4).
