Form C Door Release Relay for AX, KB, and JP Series
The RY-24L door release relay module is an interface between the door release contact on the Aiphone master station or
CEU and the actual release mechanism. The contact closure directly from the master station or CEU has limited voltage and
current capacity. Use the RY-24L 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
AX, KB, and JP Series systems when using door release and will protect the built-in contact from possible surge damage.
(Note: Use the RY-3DL when releasing more than two doors in a JP Series, or more than one door in a KB Series).
INSTALLATION:
1. Install near the power source for the door release mechanism, or behind the master station or CEU.
2. Secure wire connections with proper termination, such as wire nuts or crimp connectors.
3. Trim the wires to the desired length.
4. Trim the unused contact wire so the bare strands are not exposed.

WIRING METHOD:
(Normally Closed contact)
NOTE: The door release contacts on the station are rated at 24V AC, 500mA. The RY-24L should be used in any application
where the strike or maglock has a higher voltage or draws more current. Otherwise, internal damage to the master station
could occur.
