1.7 “Open contact” signal (ventilation function)
When locking, the interior beeper emits a series of short beeps.
This means that the system has detected that one of the wireless
magnetic contacts is open.
If none of the contacts have been opened intentionally, check all
the secured openings.
Unlike a passenger vehicle alarm system, in a caravan, you might well want
to leave a window open while all the other secured openings are monitored.
For example, if you need to ventilate the vehicle. Read the following to see
how this can be done.
Open the window you have chosen and activate the system as previously
described under Point 1.2.
When locking, the interior buzzer gives out a series of short
beeps. However, the alarm is armed and monitors all the
remaining contacts.
If the window is closed while the system is activated,
the alarm is not triggered. The alarm does not sound
until at least
5 seconds has elapsed before a window
is opened again.
1.8 “Transmitter battery low” signal
When locking, the interior beeper emits a long continuous beep.
This means that one of the batteries of a wireless transmit-
ter is low and must be replaced. This may be the battery of
a wireless magnetic contact, a wireless handheld transmitter
or a cable loop.
Each transmitter must be triggered to determine which one it is. The red
“transmit LED” of the one concerned will go out after approx. 30 seconds.
Changing the battery, see 1.9
1.9 Changing the transmitter battery
The memories of the transmitters are not volatile, i.e. once assigned, trans-
mitters do not have to be re-assigned after the battery has been changed.
To prevent the electronics from being damaged from static discharge, earth
yourself by touching an earthed part of the vehicle (door hinges or negative
contact of the cigarette lighter).
