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. Us the RY-1824L with the JP-4MED, KB-3MRD, JF-2MED, JO-1MD, JO-1FD masters and sub stations or the AX-084C, AX-248C, AX-320C central control units.

Aiphone RY-1824L – Frequently Asked Questions
1) What does the Aiphone RY-1824L relay actually do in an intercom door release setup?
The RY-1824L sits between the door release contact on an Aiphone master station or CEU and the lock itself. The contact built into the master or CEU has limited voltage and current capacity, so it can't drive most electric strikes or mag locks directly. The relay takes that low-capacity signal and switches a contact with a higher rating, which covers the majority of door release hardware. It also protects the station's built-in contact from surge damage when the lock releases.
2) Which Aiphone systems is the RY-1824L door release relay used with?
Aiphone recommends the RY-1824L for all AX, KB, JF, JO, and JP Series systems whenever door release is being used. Specifically, it pairs with the JP-4MED, KB-3MRD, JF-2MED, JO-1MD, and JO-1FD masters and sub stations, and with the AX-084C, AX-248C, and AX-320C central control units.
3) Can I use the RY-1824L relay with a magnetic lock that has to be fail safe?
Yes. The RY-1824L is a Form C relay, so it gives you both a normally open and a normally closed output. Wire the mag lock through the normally closed side and power drops to the lock when the relay energizes, which is the fail safe behavior a mag lock needs. An electric strike that latches on power goes on the normally open side instead. One relay covers either scheme, you just land the wire on the right contact.
4) Do I need a door release relay, or can I wire the electric strike straight to the Aiphone master station?
Wire it straight only if the strike's current draw stays inside the master station or CEU's built-in contact rating, and that contact is deliberately small. Aiphone's own position is to use the RY-1824L on all AX, KB, JF, JO, and JP Series systems when door release is in play. Two reasons: the relay's contact rating covers most release hardware where the station's does not, and the relay absorbs the inductive surge from the lock coil that would otherwise reach the station's contact. Replacing a burned-out master costs far more than the relay.
5) What voltage does the Aiphone RY-1824L relay run on?
18 to 24V DC. That matches the door release circuit voltage on the Aiphone intercom systems it's built for, so it runs off the same DC supply feeding the master station or central control unit rather than needing a separate transformer of its own.
6) Does the RY-1824L come with the electric strike or the power supply, or do I order those separately?
Separately. The RY-1824L is the interface relay only, ordered as a single model with no options to choose. The release device itself, whether that's an electric strike or a magnetic lock, and the power for it are separate line items, as is the Aiphone master station or central control unit on the other side of it. Plan the order as three parts: station or CEU, relay, lock.
7) I'm standardizing door release across several Aiphone entries with different lock types. Will one relay part number cover all of them?
For AX, KB, JF, JO, and JP Series systems, yes. The RY-1824L is the one door release interface across that whole range, and because it's Form C you get normally open and normally closed from the same part, so fail secure strikes and fail safe mag locks both land on it. One SKU stocked on the shelf covers the openings regardless of which release hardware each door carries.
8) Is the RY-1824L relay rated for commercial buildings or is it a residential part?
Commercial. Aiphone classes the RY-1824L as commercial door hardware, and it's an electronic access control component, not a mechanical part. That's the context to expect it in: multi-tenant entries, offices, and institutional openings running an Aiphone intercom with door release.
