WHD-15 Full Height
Security Gate
7
When the lock is operated from the control pushbutton, it is unlocked by a momentary
press of the control pushbutton which gives a potential pulse of minimum 500 ms duration.
Once the transmission is over, the lock switches to the «Open» mode and can remain in it
indefinitely.
After opening of the leaf and its return to the home position by the door closer, the latch
snaps to and makes the unlocking mechanism ready for the next opening.
The gate can be unlocked manually at any time from each side by turn the mechanical key
in the lock cylinder.
To open the gate by the key from the lock side of the gate, turn the key anticlockwise as
far as it goes and press the control pushbutton. If after that the key is put out, the next
unlocking can be made without the key by pressing of the control pushbutton.
If the key is turned clockwise as far as it goes and then put out, the pushbutton operation
is blocked and unlocking can be made again only by the key or remotely by control
impulse.
To open the gate by the key from the opposite side, turn the key clockwise as far as it
goes, unblocking the latch. If after that the key is put out, the next unlocking can be made
by either the key or remotely by control impulse.
For correct gate operation from an ACS we advise to mount a compact reed sensor on the
gate connecting it to an ACS controller so that to track the «Closed» position of the leaf.
The magnet part of the reed sensor should be mounted into the upper part of the leaf while
the sensor itself — into the gate post.
