Electronic panic lock with electric dogging (Hold back) has momentary or maintained latch and pushbar retraction. Automatic re-triggering of the latch retraction.
How electric dogging works:
When energized by optional built-in or remote switch manual,
depressing the pushpad, causes the pushpad and latch to remain
retraced (unlocked) providing push-pull door operation. When
de-enegrized or signaled by a fire alarm, the pushpad and latch
Can be unlocked mechanically on the outside using a regular rim cylinder (not included).
