Screws for mounting the power supply and shield panel included

This power supply transforms 230V mains voltage to the level required by door entry system. Standard door entry systems need only one power supply. For extended installation it is recommended to use one power supply for each entrance panel. Power supply can be mounted either on the wall or on DIN rail. The power supply is protected against short circuits.

4 Connect the power supply with the system according to the installation diagram.

The power supply is protected against short circuits. When a short circuit occurs the power supply is cut from the voltage to protect it. To reset the system, disconnect power supply for one minute, remove the cause of short circuit and connect the power supply back to the system.

Door entry systems with two separate entrances (accesses) become more and more common, especially in closed housing estates, where one panel enables entry into the estate and another to the block of flats. It is necessary to enable a user to communicate with every subscriber from each panel. Below you will find a diagram of such an installation in which Alcad products were used. It enables connecting together several control panels, installed at different entrances in one door entry system. This installation allows communication between each entrance and each subscriber as well as opening the entrance from the place where the call was received.
