4000 Series GSM Audio Intercom with Proximity
Wiring Diagrams
CONNECTING TO A GATE CONTROLLER
For a GSM4K series audio kit if the Art.4810 GSM intercom is going to be connected to an electric gate then the wires from the gate
controls can be connected directly into the C and NO relay terminals on the GSM module, as shown in Fig.27. For a GSM4KCR series
audio kit if the gate controls are going to be connected directly to the Art.4903 keypad the relay terminals C1 and NO1 can be used
(or C2/NO2 depending on the relay required), remembering to remove the respective back EMF protection jumper (JP2 or JP3), as
shown in Fig.28.

CONNECTING A PUSH TO EXIT BUTTON AND A BREAK GLASS UNIT
The push to exit button must be configured as a "push-to-make" switch and connected across terminals g & 6 on the Art.4810 GSM
PRO module. The break glass unit, configured as a "push-to-break", would only be used when connecting a fail safe/fail open lock
release (e.g. a mag lock) and would connect in series with the GSM's relay connections C and NC, as shown in Fig.29.
When the exit button is pressed the GSM relay will trigger for the programmed relay time. When the break glass unit is activated it
will break the power to the mag lock.

IMPORTANT NOTE: In instances where the current draw of the lock (fail secure or fail safe) exceeds the current rating of the
HDR15-12 (1.25A) power supply a separate power supply with a sufficient current rating will be required to power the lock.
