HOW TO CONNECT 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 aect the activation time.
A possible 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 lock in dry contact mode.
