Replacing the batteries of
the IES
When the Low Battery alarm sounds, the battery of the IES
must be replaced as soon as possible to prevent damage to the
IES.
The Low Battery alarm starts sounding when the battery
capacity is falling. In this case, you will hear a very long beep
(4 seconds) with every locking attempt.
The battery is tested whenever an authorized unlocking
operation is performed. In case of online systems, the OMEGA
Software Suite will additionally display the results of the
regular battery test in a status message. The regular battery
test is performed once per day.
NOTICE
The door cannot be opened again from the
outside once the battery is completely empty.
Always replace the battery after the first Low
Battery alarm.
If the battery is completely empty, the door can be
opened in three different ways:
using an Emergency Power Supply (see page 103,
Chapter "Emergency Opening"
using the handle on the inside
using the key for the locking cylinder (if installed).
If you program your locking devices with Master
media, setting the time of day is not possible.
