3.4 Wiring locks
The terminal supports lock types rated up to 24 Vdc at 2 A max current.
3.4.1 Wiring an internal voltage powered lock
It is possible to connect locks in a fail-safe or fail-secure configuration.
Fail-safe lock
If the terminal loses power, a fail-safe lock opens, allowing free access. Therefore, a lock that
is constantly powered, such as a maglock, must be used.
Figure 17 Magnetic lock
Fail-secure lock
In fail-secure configuration, if the terminal loses power, the lock remains closed. A lock that
requires power to open, such as a mortice lock, must be used.
Figure 18 Mortice Lock
3.4.2 Wiring an external voltage powered lock
Figure 19 Illustration of wiring for lock with external power provided
When you use an external voltage supply to power the lock the power supply ground should be
connected to GND on the I/O board and not 0V.
Note: All connections labelled 0V link to the same circuit.
