Notes regarding MEU
The MEU can be equipped with a 12 V or 24 V battery. The battery will only help to open and brake
EI
the doors when the mains power is lost. The battery is not a part of the escape system and will not
be monitored when monitoring of the emergency unit is performed, only the elastic cord will be
monitored.
Note! To test that the battery is functional, set the mode selection to AUTO and then break the
power to the operator. Observe the door, the elastic cord will open the door and the battery will
brake the door before reaching fully opened position (the doors will not slam into the door stops).
If the operator does not decrease the speed of the door, the battery needs to be replaced by an
ASSA ABLOY Entrance Systems-authorized representative.
Electrical Emergency Unit (EEU)
EEU consist of rechargeable batteries.
EEU can be used in escape route.
Emergency monitoring with EEU and MEU
According to standard it is a demand that the EEU or MEU shall be monitored on a regular time basis.
The monitoring is performed by opening the door with help of the emergency unit. Half an hour
before this time has elapsed the following opening impulse generates an emergency opening test.
If there is no opening impulse within this half hour, the operator control unit generates a monitoring
test itself.
If the emergency unit opens the door within the limited time the test is successful and the door re-
sumes the function set by the operation mode selector.
Note! The test is never performed in operation mode selector setting OPEN. In setting OFF it can be
selected. The test is always performed after a RESET and after changing operation mode selection,
from a position where a test is not done to a position where the test is a demand.
Fire closing
When the power is lost the door will close. This demands 12 or 24 V battery.
Fire closing with repeated closing
If the mains power is lost and the door is opened by hand after an electrical emergency closing, it
will close again. This demands 12 V or 24 V battery and a LSK.
Break-out unit PSB
Can be used in escape route and enables door and side screens to be broken outwards in case of
emergency.
See page 22.
Interlocking
Used between two operators when the first operator must close before the other one can open
(typical to reduce energy losses and not for security reasons).
Convenience battery UPS
Stand-by supply which gives continued operation during short power failure, the operator can run
without mains power for 20 minutes.
External error indication
Obtained if a lamp or a buzzer is connected.
Key switches (flush and/or surface mounted)
Used to give opening impulse to the door in any operation mode selector setting. The key switch
can also open the door when power is switched off, if a battery is fitted.
