Grandstream Networks GSC3570 User Manual page 12

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.
Connecting GSC3570 with 3
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.

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.
