Use with hold-open devices (continued)
6. Reactivation of operator (manual reset).
This manual reset has to be effected by a user on site. It does
not matter in which way the system has been triggered.
There are several ways to reset system:
Reset by moving door:
1. Reset smoke detector (its LED is green).
2. Close door fully.
3. Open door until it has reached adjusted opening
width.
4. Release door.
Reset via program switches:
1. Reset smoke detector (LED is green).
2. Set program switches to "OFF" and then back to
previous function.
Smoke/fire doors are important for personal safety.
It is thus essential that these doors can close reliably
and without any hindrance in case of danger.
Therefore, never use additional wedges or similar
items to hold door open, as they may prevent door
from closing in case of an emergency.
