Electric locks
Normally closed and normally open relay contacts, are programmable for a wide
range (0 ... 255 sec) of lock operation time. Thus panel may control a wide range of
electric locks and latches of almost any type.
The example of actuator connection is on the Fig. 16. The first is powering the lock
and second by depowering.

. Connecting locks
When using relay to turn on / off current via inductive load, for example, to run
electromagnetic lock, there are electric pulses of high amplitude. To prevent damage
of relay contacts shunt inductive load by diode, set in opposite direction to voltage of
coil supply
Remember, that low-cost solenoid latch do not allow long power supply. For these
latches program the lock time as short as possible to prevent coil overheating.
Assign relay outputs as outputs of locks at panel programming for proper operation.
Sirens and Bells
Electric bell (see Fig. 17) are inductive load for voltage source. When connecting a
bell to DC source it is necessary to use a protective diode (see warning about the
inductive load).
Fig. 17
. Connecting bells
When using custom actuators (magnetic starters, turnstiles, etc.), refer for advice to
your hardware vendor.
When the lock time is equal to 0 pulse duration of 200 ms will sent to relay.
Do not use diodes for connecting actuators to AC power supply.
Read the instructions when connecting sirens. Current consumption of sirens
should not be more than 1 A
For proper operation of the siren assign the relay output as a siren output
(alarm, etc.) when programming.
