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 GDS3705
2) Pick up the Alarm Phone Call (if configured)
3) Open Door using PIN (either public PIN or private PIN)
Once alarm triggered, the GDS3705 will play siren sound, send email to administrator (if configured SMTP);
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.
Below are some diagrams showing the correct wiring to enable this new security enhancement feature.
