An entrance panel can control 2 locks if you connect the SH-42 module to the RS-485 interface of the panel. SH-42 has 2 relays for lock opening.
The 1st lock opens by pressing * or # symbols. To open the 2nd lock, you must press 0. These DTMF symbols are default, so you can change them into any other at the Access management tab of a device web interface.
