Emergency unlocking of the escape door
control system
TT If the emergency switch in the door
terminal is operated, the locking element
is unlocked immediately.
In this case, the emergency switch control
element remains in the „Emergency
unlocking" condition until it is manually
reset.
Ext If the system is linked to a fire alarm
system or central emergency unlocking
unit, the external closed circuit signal will
be delivered to two spare operating
relays (terminals 22/23).
The power supply for these can be tapped
from connecting terminals 1 and 2 of the
escape door control unit or be affected
through an external 24 VDC power supply.
If no fire alarm system or central
!
emergency unlocking unit is connected,
the relays (connecting terminals 22/23)
must be connected direct to the power
supply at terminals 1/2.

closed again, the „Sabotage" indicator
lamp goes out and the acoustic signal
emitter is switched off.
