SYSTEM CONFIGURATION:

LEM-1DL with Door Release contact activating a Normally Closed relay for a Magentic 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 3rd party relay of similar specifications may also be used. Refer to manufacturer’s documentation for connection details.
