DOOR - LOCKINg DEVICES
Each 2-Door Controller Module has two lock outputs and each of these outputs is associated to a reader input.
When the LOCK OUTPUT is configured (see “Jumper Settings” on page 17) to provide power (12Vdc), the LOCK
OUTPUT is protected by a fuseless protection monitoring algorithm and will shutdown if the current exceeds
750mA @ 12Vdc. When interconnecting to an alarm system, we recommend to use the LOCK OUTPUT in its
DRY CONTACT Configuration (see “Jumper Settings” on page 17).
• If you have one door with a reader on each side of the door, you can use either lock output.
• You can program the lock outputs to function in “fail-safe” (remove power to unlock a door) or
“fail-secure” mode (power required to unlock a door).
• When using Electronic Mag Clamps or similar devices ensure that the current specifications are not
exceeded.
Always consult the regulatory agency in your area for existing regulations regarding doors designated
as emergency exits.
Jumper Settings
The jumpers LOCK1 and LOCK2 must be set according to the door devices used. For a 12Vdc locking device
(magnetic or strike), it can be connected to the terminals and the jumpers set in 12Vdc power mode on VLK+.
Use either the NO or NC Lock Output Contact depending on the FAIL SAFE or FAIL SECURE connection mode.
If the lock (or electromagnetic) requires 24Vdc, the lock output must be used in its dry contact mode and an
external 24Vdc power supply must be used. The same applies if the Locking Device requires an alternating
current supply (Vac).
