Open/Close Impulse; Power Failure Mode (Backup Batteries Are Installed) Optional - Assa Abloy SW300 Installation And Service Manual

5 How the ASSA ABLOY SW300 and ASSA ABLOY SW150 work
5.5.5

OPEN/CLOSE impulse

The impulse will open the door and the door will stay open until a new impulse is given. If no impulse
is given the door will close after 15 minutes. This can be made infinite by changing group of para-
meters, see page 82.
OPEN/CLOSE impulse works only in program selection AUTO. Can be programmed for OFF and EXIT
as well.

Power failure mode (backup batteries are installed) optional

• In case of power failure, normal operation can be carried out with impulses from the KEY SWITCH.
• Two contacts are available for connection of 2 x 12 V batteries (NiMH).
• DIP-switch for monitoring of batteries is also available. Faulty battery will be indicated by the
LED on the CU-ESD. If selected the relay on EXU-SA can give a contact information. An audible
warning signal can be achieved by using the accessory board AIU. It is connected to the 24 VDC
and plugged into the EXU-SA relay output terminal. The Battery Monitoring always has to be
reset, when the batteries have been replaced. It is done by pressing the Learn button, while
battery mode is active (mains disconnected).
Note! If battery mode is POWER SAVE, the reset has to be made during the door is opened by
Key impulse.
• During POWER FAILURE the operator will finish the actual operating cycle and then switch of
the battery supply. The battery powered operator can be reactivated to achieve a new operating
cycle by an impulse on the KEY input.
• The operating mode during battery power can be changed from POWER SAVE to CONVENIENCE,
see page 82. During CONVENIENCE MODE the operator will work as normal until the batteries
are discharged. The batteries are rechargeable and will be charged by the control unit in the
operator. New, fully charged batteries can typically open and close a door max. 300 times in
convenience mode. In power save mode the operator can stand-by in up to 1 week, waiting for
KEY impulse.
The following sensors are not active during battery operation POWER SAVE mode.
- Mat
- Overhead presence detector (OPD/OPS), frame mounted
- Presence impulse approach, door mounted
- Presence detection swingpath, door mounted
Note! All sensors works normally in CONVENIENCE MODE.
