Wiegand RFID Card Reader Example
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
COM
x port to
DI
x 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 , Option valid only for the GDS3710 Model)
Once alarm triggered, the GDS371x 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.
Below are some diagrams showing the correct wiring to enable this new security enhancement feature:
GDS371x Connection: IN2 set as Normal Close and “Fail Safe” Electric Strike using 3 Party Power Supply
Digital Input set as Normal close
Fail safe” Electric Strike using 3rd Party Power Supply
GDS371x Connection: IN2 set as Normal Open and “Fail Secure” Electric Strike using 3 Party Power Supply
