Magnetic Lock
Note: For applications requiring a Normally Closed (N/C) contact (Magnetic locks, etc.), an external
relay should be chosen based on the lock’s power source.
When using a 12-18V DC magnetic lock, Aiphone’s RY-18L relay may be used.
For 24V DC magnetic locks, Aiphone’s RY-24L relay may be used.
A 3
rd
party relay of similar specifications may also be used. Refer to manufacturer’s
documentation for connection details.
