GDS3710 – IP Video Door System
One-Way Doors Interlocking Configuration Guide
INTRODUCTION
One-way interlocking doors mode on GDS3710 allow to control two doors for
access control in one-way mode. Once the card or PIN is fully validated by the
GDS3710, it will check the status of both doors (using 3rd party window/door
sensors – not provided by Grandstream – to verify if they are opened or
closed), if both doors are closed the Door 1 will open allowing the person to
pass through hallway, once the Door 1 is closed it will start counting and
when the timeout is reached, the Door 2 will open granting access to the
person in the facility.
This feature can be used in application scene
like: College Dorm, Bank Branches, Government Offices, Medical Clinics,
Private Clubs, etc., where there are two doors in place, high security and
flow control is required (only one entry per time) but security guard may not
be on site always.

FUNCTIONALITY
One-way interlocking doors mode will allow GDS3710 to control two doors in one
direction, with additional 3rd party window/door sensor installed accordingly
(not provided by Grandstream).
When configured and wired correctly, the two doors will operate under a
controlling logic as below:
- Only legal PIN or RFID card can open door when BOTH doors are detected closed.
- When 1st door opened by valid user, the 2nd door is and will remain closed; the 2nd door will automatically open once detected the 1st door closed and programmed timer reached.
- When 2nd door opening, the 1st door will NOT open even if a valid PIN/RFID is used.
- If entering 1st door and after 1st door closed and 2nd door opened, the person failed to enter 2nd door promptly (after 2nd door opening time out) will be locked in between two doors until next transaction happens or ask help (e.g.: call posted number or press button if there is one) from security staff to open door remotely (via SIP call into GDS3710 or GDSManager, for example) .
This open-door logic will make sure two doors are open in “One-Way” direction, at any given time only one door can be opened, and only one legal open-door request is allowed to execute. The hallway or scene between two doors could be monitored by installing Grandstream IP cameras.
WIRING DIAGRAM
The example below shows how to use wiring on the back cover of the GDS3710 to
connect with 2 external Lock strike “Fail Secure Model” and 2 Door Sensors:
Under this diagram the GDS3710 will be placed in Door 1 in order to control
the two doors allowing one- way (entrance from Door 1 to Door 2) to the
facility
Note: If required to use the same two doors for “Exit” direction, another
GDS3710 is required and can be configured in Door 2 to control “Exit”
direction. The wiring/connection will be mirrored.
GDS3710 WEB CONFIGURATION
For example, the GDS3710 can be installed to control 2 doors using one-way interlocking door mode when enable this feature please do the following:
- ALMOUT1 Feature: Open Door
- ALMOUT1 Status: Normal Open
- Control Options: Door1 & Door 2 Checked
Notes:
-
Door 2 Delay before Unlock(s): Will be the total transit time from Door 1 to Door 2 right after the Door 1 is closed (this time will be “Door 1 unlock holding time”).
In above example, the Door 1 unlock holding time is 2 seconds, the transit time of hallway is 6 seconds, therefore the Door 2 Delay before Unlock is set to 8 seconds. The transit time and unlock holding time will be decided and adjusted based on actual application scene by the installer or system integrator. -
COM1 (ALMOUT1) only has two sockets for wiring, and NO ONLY. If the connected strike/lock is a NO strike, this means ALMOUT1 Status should be set to “Normal Open” then door will be closed when power is lost.
Digital Input to Check Door Status (Door 1 & Door 2): 
Go to Alarm Settings → Alarm Events Config → Digit Input 1 & 2, configured
as follow:
Digit Input 1: Door Status Check. The DI will validate the current status
of the Door, whether it is close or open, based on the sensor signal sending
to the “Digit input 1”
Digit Input 1 Status: If set to Normal Open : Configured door status
check will be triggered when Digital Input Status switch from Close to Open,
If set to Normal Close: Configured door status check will be triggered when
Digital Input Status switch from Open to Close. By default, Input Digit 1
Status is “Disabled”.
Digit Input 2: Door Status Check. The DI will validate the current status
of the Door, whether it is close or open, based on the sensor signal sending
to the “Digit input 2” Digit Input 2 Status: If set to Normal Open: Configured
door status check will be triggered when Digital Input Status switch from
Close to Open, if set to Normal Close: Configured door status check will be
triggered when Digital Input Status switch from Open to Close. By default,
Input Digit 2 Status is “Disabled”.
Notes:
- “Alarm Schedule” and “Alarm Action Profile” must be configured and selected otherwise the Digit Input channel will not be activated.
- There are two doors wired with window/door sensor separately, please make sure the door sensor is wired to correct Digit Input channel and refer to below sample wiring diagram for reference.
Private PIN or Card & Private PIN:
If using RFID card or Private PIN to open door, then which door
can be opened by the RFID card or Private PIN is configured via “Card
Management”, see above screenshot.
Note: Once the card or Private PIN is fully validated the GDS3710 will
check the Door status for both doors if and only if both doors are closed,
they will open following the interlocking doors mode.
