Add selective door-release control to a compatible Aiphone intercom system with the Aiphone RY-3DL Selective Door Release Adaptor.

Designed for multi-door intercom installations, the RY-3DL provides three independent Form C dry-contact relay outputs, allowing the system to release the specific door where communication is currently established.

The relay provides both Normally Open (N.O.) and Normally Closed (N.C.) contacts, making it suitable for controlling compatible electric strikes, magnetic locks, and other electrified door hardware.

Selective Door Release

The RY-3DL allows a compatible Aiphone master station to control multiple entrances without requiring a separate door-release button for each door.

When communication is established with a particular door station, activating the door-release command operates the corresponding relay for that entrance.

This makes the RY-3DL ideal for systems with:

• Multiple building entrances

• Several controlled office doors

• Front and rear entrances

• Multi-tenant facilities

• Security vestibules

• Commercial access-control systems

Three Form C Relay Outputs

The RY-3DL contains three independent Form C dry-contact outputs.

Each relay provides:

Normally Open – N.O.

Commonly used with fail-secure electric strikes and locking devices that release when power is applied.

Normally Closed – N.C.

Commonly used with fail-safe magnetic locks and hardware that releases when power is removed.

Contact Rating:
1A at 30VDC
1A at 50VAC

Compatible Aiphone Systems

The RY-3DL is designed for compatible Aiphone systems including:

• JP Series

• JF Series

• KB Series

• Select legacy IE Series applications

Always verify the specific master station and system wiring before installation.

JP Series Application

When used with the Aiphone JP-4MED, the RY-3DL can selectively release doors 1, 2, and 3.

Aiphone documents configurations where:

• RY-3DL controls Doors 1–3

• An additional relay such as the RY-24L can be used to control a fourth door

The master station is programmed so the appropriate release relay becomes available based on the active door station.

Wiring Distance

Maximum distance from the master station to the RY-3DL:

22 AWG: Up to 165 ft
18 AWG: Up to 330 ft

Always follow the wiring requirements for the specific Aiphone system.

Electric Strike Applications

For an electric strike, use the appropriate Normally Open contact.

Typical compatible applications include:

• Electric strikes

• Electrified latch-release hardware

• Fail-secure locking devices

The lock's power supply is wired separately through the relay contact.

Magnetic Lock Applications

For a magnetic lock or other fail-safe device, use the Normally Closed contact.

The relay interrupts lock power when door release is activated.

All magnetic-lock installations must comply with applicable building, fire, and life-safety codes.

Ideal Applications

• Commercial office buildings

• Schools and universities

• Healthcare facilities

• Government buildings

• Multi-door entrances

• Security stations

• Apartment and multi-tenant facilities

• Reception desks

• Card-access entrances

• Video intercom systems

Important Ordering Information

Before ordering, verify:

• Existing Aiphone intercom series

• Number of doors requiring selective release

• Lock voltage and current

• N.O. or N.C. relay requirement

• Electric strike or magnetic-lock operation

• External lock power-supply requirements

The RY-3DL provides relay switching only and does not serve as the primary power supply for the electric lock.
