- INSTRUCTIONS -
The RY-1824L 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-1824L 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, JF, JO, 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 JF or 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.

NOTE: The door release contacts on the station are rated at 24V AC/DC, 500mA. The RY-1824L 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.
