Secure Open Door Peering with GDS37xx
This feature requires GSC3570 and GDS3710/GDS3705 paired together to function. With GDS3710 or GDS3705 installed
outside, the GSC3570 is installed inside, the strike or lock is wired directly to the Alarm_Out interface of GSC3570 to control
the door from inside, therefore more secure compared to the strike wired directly to GDS3710/GDS3705 at outside. Below is
the application scene illustration:
Figure 15: Secure Open Door Peering with GDS37xx
Notes
Only ONE GDS37xx can be paired with GSC3570 for such Virtual Button Open Door
If user configured multiple GDS37xx for such Virtual Button Open Door, the device would NOT prompt the error, but the
new input will overwrite the old input, and only the LAST input GDS37xx will work with corresponding Virtual Button in
GSC3570.
Notes
GDS3710 firmware 1.0.7.19 or above / GDS3705 firmware 1.0.1.13 or above, are required to work with GSC3570.
Only one door can be controlled due to GSC3570 only has one Relay Control circuit.

Connecting GSC3570 with 3 Party Door Access Systems
By selecting and configuring the supported related 3 party door access system here, when GSC3570 is in SIP call with DTMF
open door operation, the “Soft Button” preprogrammed will appear in the GSC3570 touch screen. The user will be able to
press the soft key to send the Open Door PIN to a related 3rd party door access control system to open the door.
This is an enhancement to help system integrators and customers to integrate GSC3570 with 3 party Door Access Control
system to operate the open door remotely.
Figure 16: External Service 3rd Party Door Control Systems: Web Configuration
Using GSC3570 as Doorbell and Door opener
The GSC3570 can behave like a doorbell and an open door if the door strikes wired directly to the relay control port of the
GSC3570. For licensed electricians, this is a perfect digital upgrade solution for users with a broken traditional analog doorbell
system. The existing wiring and switch can be connected to GSC3570 so when visitors press the door switch the GSC3570 will
play DING-DONG doorbell tone. If connecting the electrical strike directly to the GSC3570 relay control port, a 3d party
audio/light strike device can be configured to be triggered when the GSC3570 receives an incoming call, then the user can
press the Open-door Icon from GSC3570 to open the door directly. It can combine with the GSC36xx IP camera to form an
absolution package.
If multiple doors need to be controlled by GSC3570, SIP call is required, and the door strike/relay should be controlled by
related GDS37xx directly.
The GSC3570 will turn on LCD when device in energy save mode (LCD Off) when secure open door event happened.
When receiving an incoming call, a 3rd party audio/light strike device can be triggered by Door Open Port.

rd
rd
Note
Starting from firmware version 1.0.5.21, The number of external service operations supported has been increased from 10 to 20.

Figure 17: GSC3570 as Digital Doorbell and door opener example
This feature is designed to allow GSC3570 to function like a traditional doorbell, and open the door if wired to an electric lock,
a simple digital upgrade to a traditional (broken) doorbell. If combined with an IP camera, it can help to monitor and update
the home security without paying the subscription fee usually involved for such a service.
The wiring example of GSC3570 as doorbell and open door:
Figure 18: GSC3570 as Digital Doorbell and door opener wiring example
Wiring:
1. A switch (doorbell button) needs to be wired to AIN1 (Blue), AIN2 (Brown) or AIN3 (Grey) and Ground (Black).
2. The label is printed in the back of GSC3570 and a cable with color code is provided with the package. Maximum 3
switch/button can be connected (example: Front Door, Back Door, Garage Door) But ONLY 1 electrical lock or strike can
be controlled (because GSC3570 only has 1 relay control port (COM1, NO1/NC1).
Configuration from Touch UI Screen:
Below are the screenshots of how to configure and enable this feature. This feature is revised from Zone/Alarming feature;
therefore, THREE steps are required:
I. DO mode set to “Alarm out” or “Open door”:
1. From touch UI, press “Settings”, select “DO settings”

2. Choose “DO mode”, select “Alarm out” if no door strike connected and only want to use the Ding-Dong doorbell tone. No
virtual open door button will be displayed in Alarm Message.
3. Choose “Open door” if COM1, NO1/NC1connected to strike to control door opening. Green virtual open door button
when be displayed in Alarm Message when doorbell switch pressed
4. Press “<” to exit and select “√” sign to save the change just made.
Figure 19: DO mode set to “Alarm out” or “Open door

Open Door via GDS37xx with or without a SIP Call
This feature is requested by customers and implemented to meet customer’s application requirement, where GDS37XX paired
with GSC3570 to open door while no sip call required.
This feature needs related matching GDS37XXfirmware to work. The minimum firmware version needed:
GDS3710: 1.0.7.19 or higher.
GDS3705: 1.0.1.13 or higher.
From GDS37XX side, the configuration is the same. Only difference is the number of doors be controlled: If using Local Relay
controlled by GDS37XX, TWO DOORS can be controlled.

If using GSC3570 Relay, ONLY ONE DOOR can be controlled. The PIN and other settings are the same as SIP remote open
door or GSC3570 secure open door.
The difference will come out at the touch screen UI operation of GSC3570.
