Button
Harness
Pre-wired button harness connection (CN6). Refer to
Fig.3
and button harness table on page 7 for wiring colour
codes and button configurations.
USB CONNECTION (CN1)
The micro-USB connection allows the VR4KGSM module to be connected to a laptop/PC for ease of programming (refer to page 28
for connecting the GSM module to a laptop/PC). Further information on programming using the GSMSK PC software can be found
in the following manual:
GSMSK-66251720-EN-V1-3
(or later version)
UIM-138 (DISPLAY HARNESS INTERFACE CONNECTION, CN3)
The UIM-138 connection allows the VR4KGSM module to be connected to the display interface module, the VR4KDM, (refer to page
20 for connecting the GSM module to a VR4KDM module.
WIEGAND (WIEGAND PROXIMITY READER HARNESS CONNECTION, CN5)
The Wiegand connection allows for a Wiegand proximity reader, the VR4KPPM, to be connected to the VR4KGSM module (refer to
page nn for connections). Further information on programming proximity fobs/cards can be found on pages nn - nn of this manual.
BUTTON HARNESS CONNECTIONS (CN6)
The pre-wired button harness is used to connect the buttons and button modules (described on page 6) to the VR4KGSM module.
For complete button harness wiring refer to
Fig.3
and the button harness table on page 7.
CALL PROGRESS LED’S
LED
(sign)
Description
SPEAK
(Yellow)
The speak LED when illuminated, indicates that it is possible to speak because the call has been
answered or a call made to the GSM intercom (with the exception of a call from a dial to open (
DTO
)
number). The LED will switch OFF at the end of a conversation when the telephone/mobile that has
been dialled hangs up or at the end of the call time (
SPT
).
BUSY
(Red)
The busy LED when illuminated, indicates that it is not possible to make a call because a call or a
conversation is in progress. The LED will be OFF when the system is in standby. If there is power on
the GSM intercom and the Art.432 antenna is not connected this LED will flash continuously until the
antenna is connected. The LED will flash while connecting to a network and continue to flash until it
has found the network.
OPEN
(Green)
The open LED when illuminated, indicates that the door lock (GSM relay) has been operated. It will
switch OFF at the end of the programmed “door opening” time. The LED will also illuminate and operate
the relay (for the programmed relay,
RLT
, time) if a programmed key fob is presented to an off board
Wiegand proximity reader that is connected to the Wiegand reader input connections.
