Connecting Lock Hardware
Magnetic Lock
The ALK370x – IP controllers will support any
12Vdc magnetic lock up to a maximum overall
load of 800mA. The 12Vdc required to
energise the lock is supplied and switched by
the controller via the LK1 and 0V terminals.
Ensure the lock mechanism you are
connecting has Back EMF Protection – most
have. If not a Back EMF Diode of type 1N4001
or equivalent must be fitted.
Door Strike
The ALK370x – IP controllers will support any
12Vdc magnetic lock up to a maximum overall
load of 800mA. Door strikes are available as both
fail secure and fail safe. Both types require 12Vdc
to operate, however a fail secure door strike is
locked when no power is present and requires
12Vdc to release the mechanism, a fail-safe door
strike is unlocked when no power is present and
requires 12Vdc to lock the mechanism.
Both types of mechanism are supported by the controller. The wiring is identical for
both types, see Figure 3.3. The lock type is selectable when configuring the
controller (see next chapter).
When connecting a door strike to any ALK370x –IP pay special attention to the Back
EMF Diode. This must be fitted. Failure to do so could result in the controller being
damaged when the lock mechanism is de-energized.
The Back EMF Diode should be of the type 1N4001 or equivalent.
