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 mo-
ment. You don't need a power supply for the lock and the door opening time programmed does not affect the activation time.
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 peculiar climate conditions, we suggest to use the "open
door" relay in "dry contact" mode.

OPERATION
Once the device has been programmed and connected correctly, it will generate upon each pressing of a push button, a code correspond-
ing to the PHONE ID (address programmed on the 8 way dip-switch inside each telephone) of the telephone being called.
TO CALL A USER
Press the relevant button to call the user: 2 quick beeps will indicate if the system is busy, otherwise the call will be signalled by a
slow intermittent acoustic signal until the call is answered, the conversation time expires (programmable time) or the call is inter-
rupted by pressing a push button for a minimum of 2 seconds.
A short intermittent acoustic signal plus the relevant LED switched ON indicates that the door is open. If a wrong push button is
pressed or if there is no answer, a new call will cancel the previous one.
MOUNTING NOTES
When an expansion button module (Art. 404x)
is used combined with speaker units with inbuilt
camera (Art. 4384-1, Art. 4384-2, Art. 4384X-1,
Art. 4384X-2) remember to set the expansion
modules properly in order to avoid overwriting
the addresses; indeed the inbuilt buttons ad-
dresses are already set (Fig. 7).
