Independent of switch position (ON /OFF), the “latch check” complies with the ANSI 156.19 requirements.
Position OFF: Smooth closing, to be used on doors without lock.
Position ON: More powerful closing, to be used on doors with lock, to overcome binding in the locking
device.
1)
If the switch is set to ON, the LOCK RELEASE is active during the opening delay time set by the potentiomet-
er.
For PAIR OF DOORS installations, the LOCK RELEASE works in sequence: First the MASTER then the SLAVE.
2)
Note! Lock only functions when Program Selector is in OFF or EXIT.
After changing any system selection a new LEARN must be carried out.
