When the Wiegand output of the GDS3710 is connected, it acts as the signal receiver of the 3
rd
party
Wiegand device, connecting to door controller. The major wiring is GND, D0, and D1. Because usually the
door controller will consume big current and power, the power supply should be separated.

Siren alarming when door opened abnormally
When this feature enabled (special wiring required, see below wiring diagram), abnormal open door will be
detected by DI port (Alarm_In2 or IN2 in below diagram showed) if wired correctly (connecting the COMx
port to DIx port) therefore trigger siren alarm. Once abnormal open door alarm triggered, the siren will sound
non-stop, until manually override by related person.
There are several ways to stop and disable the alarm:
1) Power cycle the GDS37xx
2) Pick up the Alarm Phone Call (if configured)
3) Open Door using PIN (either public PIN or private PIN)
Once alarm triggered, the GDS3710 will take snapshots when the abnormal open door happened, email
and upload the snapshots to FTP or Central Server (when configured); call the configured alarm SIP phone,
send the alarm output (if connected). User will only be able to disable the siren using the 3 methods
mentioned above.
Detailed action information please refer to GDS37xx User Manual, “Alarm Action Settings” configuration.
