HOW TO CONNECT AN ELECTRIC LOCK
The "door-open" relay can operate either as "dry contact" or "capacitive discharge" mode.
• In "dry contact" operation mode the relay works in a traditional way, a power supply or a power source is needed
to operate the lock (12-24Vac/dc 2A max), and activation lasts according to the door opening time programmed.
• In "capacitive discharge" operation mode the relay's contacts, when active, supply directly the lock (12Vac/
dc 1A max) for a moment. You don't need a power supply for the lock and the door opening time pro-
grammed do not affect the activation time.
* NOTE: in "capacitive discharge" modality the relay time cannot be more than 6 seconds because it could overhead
the device.
A possibile deterioration of the mechanical performance of the electric lock, might cause the "capacitive discharge" to malfunction
in time. In case the electric lock is used in very dusty environments or in an abnormal climate condition, we suggest to use the "open
door" relay in "dry contacts" mode.

OPERATION

Once the Art. 4204X has been programmed and connected correctly, it will generate upon each pressing of a push button, a code corre-
sponding to the PHONE ID (address programmed on the 8 way dip-switch inside each telephone) of the telephone being called.
