Each relay has a group of switching contacts (COM common contact, NC normally closed, NO
normally open).
The first relay controlling the first door lock
The second relay controlling the first door lock
The first relay controlling the second door lock
The second relay controlling the second door lock
Table 12. Using the controller relay to connect locks
In order to support a variety of lock models, two modes of controlling the locks are implemented:
potential and pulse.
In potential mode, the first lock relay is active in a locked state, the second one is inactive; and vice
versa in an open state. The use of two relays allows, e.g. utilizing electromagnetic latches both for
unlocking and locking by voltage supply.
In pulse mode, both relays are inactive. When locking the lock, the first relay is briefly activated;
respectively, the second one is briefly activated, when unlocking the lock (for response pulse
duration, refer to Sec. 15 Appendix 3. The controller numeric configuration parameters, D0003
parameter). This mode allows controlling electromechanical locks.
8.3.1 Connecting electromagnetic locks or latches
The controller allows you to control all types of electromagnetic locks or latches. Electromagnetic
locks are usually locked, when voltage is supplied to them.
Electromagnetic latches can act both for unlocking and locking by voltage supply.
It is strictly forbidden to use electromagnetic latches unlocking by voltage supply
but not providing long-lasting work, when voltage is supplied!
When unlocking the door by controlling software or in the event of fire, the
voltage is being supplied to the latch for a long time. The use of latches that can
withstand only a short-term voltage supply (e.g. FERMAX) will cause burnout of
latch winding and its uncontrolled locking, which may lead to loss of life!
For controlling electromagnetic locks and latches, the controller should be switched in the lock
potential control mode (for the first door toggle of CONF1 dip-unit to be set in OFF position,
for the second door dip-unit to be set in OFF position).
