VRVK/6358 Series - Installation handbook
When the door open relay operating mode is set to “capacitor discharge”*, one terminal of the electric lock must be connected to
ground while the second must be connected to “NO” terminal. The “NO” terminal will supply a temporary voltage when the speaker
unit receives the door open command. In “dry contact” mode the “NO” terminal is internally linked to “C” terminal when the speaker
unit receives the door open command.
* When “capacitor discharge” operating mode is set, one terminal of the electric lock must be connected to the ground while the
second one must be connected to “NO” terminal. The “NO” terminal will supply a temporary voltage when the speaker unit receives
the door open command (we suggest to use a 12Vac/dc 1A max electric lock). Setting “dry contacts” operating mode, when the
speaker unit receives the door open command, the “NO” terminal will be internally linked to the “C” terminal for the programmed
time (switch 4 of the 4 way dip-switch bank).
