Description of terminals
Telephone line
Polarity does not matter. Can be connected directly to a
private telephone network (PSTN), PBX or GSM
gateway line.
CAUTION – more than one unit may not be connected
to a single line!!!
ALARM

*) 12 – 24V DC voltage,
any polarity Emergency call

Indicator connecting
terminals *)
Indicators (backlit pictograms), max. 24 V / 2× 200
mA, supplied from an external power supply, the
connection layout must be maintained.
External microphone
connector
External microphone is available on request. Switching
between onboard and external microphone is
automatic (external microphone is detected). ***)
External loudspeaker
connector For a request, loudspeaker can be equpped with cable.
In this case, it is connected here.
Induction
loop
connector
The induction loop is not a part of standard packing.
It has to be placed behind a non-metal, non-magnetic
cover in the control panel because the magnetic field of
the induction loop cannot go through the metal lift
control panel.
Notes:
 If loudspeaker is placed behind a non-metal, non-
magnetic cover, it works as the induction loop too.
 Output is short circuit resistant. Output power is
limited by resistor.
Lift blocking contact *) **)
In the event of telephone line failure, the contact opens,
the lift goes to the nearest floor and the door opens. The
lift should not go on until the telephone line function is
restored.
Switch 2 contact *) **)
The switches can be used as needed and are remotely
controlled using a digital password (DTMF). The switches
are not designed for 230V!
Switch 1 contact *) **)
*) These terminals are safely electrically isolated from the telephone line.
**) Extending module terminals. The lift blocking module can be mounted only if switch
2 is absent.
***) Applies to boards of version 5 and higher. These boards has both onboard
microphone and the connector for external one.
