3.2.1 Notes on the use of an electronic door opener
There is an increased risk of burglary if you connect a door opener as the relay
contacts for activation of the door opener are accessible following disas-
sembly of the DoorLine.
An electric door opener does not substitute door closure by a locking bar, it is
an intelligent, additional safety feature.
It is primarily intended for daytime operation, whereas at night time or in case
of absence the relevant door is locked by the locking bar.
As far as insurance is concerned, a door that is held closed only by the use of
the door opener is not regarded as locked!
3.3 Technical prerequisites
▪ The device is designed for connection to an analogue telephone connec-
tion (a/b-Port) of a PBX system.
▪ Both relay switching outputs of the device connect potential-free. This
means that when a door opener or a similar device is activated, it may be
necessary to provide an additional bell transformer (see chapter Connect-
ing device [
} 12]).
▪ The installation of your PBX system and its operation require the use of tele-
phone plugs (e.g. TAE or RJ11), cables and lines that are not included in the
scope of supply.
▪ Your PBX system and end devices (telephones) must support touch-tone di-
alling (DTMF).
