Form C Relay for 12-18V DC Intercom Systems with Door Release
The RY-18L door release relay module is an interface between the door strike contacts on the Aiphone master station
and the actual release mechanism. The contact closure directly from the Aiphone master station has limited voltage and
current capacity. Use the RY-18L to ensure that the contact rating will be sufficient for the electric strike or magnetic lock
used. The relay's contact rating supports a majority of door release hardware available. This relay is recommended for all
JF, JK, and JO Series when using door release, and for the LEM-1DL or LEF Series when connecting a maglock.
(Note: Use the RY-3DL when releasing more than one door in a JF Series).

INSTALLATION:

1. Install near the power source for the door release mechanism, or behind the intercom master station.
2. Secure wire connections with proper termination, such as wire nuts or crimp connectors.
3. Trim the wires to the desired length.
4. Cut the unused contact wire so the bare strands are not exposed.
