Aiphone RELAY RY-18L Instructions

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 unit and the
actual release mechanism. The contact ratings on Aiphone units vary, and are all Normally Open. If your strike or
maglock is a higher voltage or draws more current than specified for the unit, the RY-18L is required. It provides either a
Normally Open contact for an electric strike, or a Normally Closed contact for a magnetic lock. The contact rating
supports a majority of door release hardware available on the market. This relay is recommended with all MK, JF, and JK
systems when using the single door release feature, and for the LEM-1DL or LEF systems when connecting a maglock.
INSTALLATION:
1. Install in a suitable location, either near the power source for the door release mechanism, or behind the intercom.
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.
