Aiphone RY-ES - External Signaling Relay

The RY-ES is a signaling relay that fires when a door station calls in, so you can drive an external device like a horn, strobe, or remote chime. It wires to the chime output of the master station, which is how you extend a call to a shop floor, warehouse, or any area where the master station's own tone won't be heard.

Call extension with the RY-ES works on the JP, JO, JK, JF, KB, AX, NIM, DB, and IE systems. The one exclusion is the IE-8MD, which it is not used with.

No separate supply is needed. The RY-ES shares power with the master station it connects to. It takes 12-30V DC or 12-16V AC, drawing 10mA standby and 60mA max on DC, or 15mA standby and 70mA max on AC, so budget that against your master station's available power.

Yes. The RY-ES connects to the master station's chime output in place of the IER-2. Note the difference in what you get: the IER-2 is an add-on speaker, while the RY-ES gives you a dry contact you can use to trigger whatever signaling device the site needs.

No. The Aiphone RY-ES is a call-extension relay that connects to the chime output of an Aiphone master station and shares power with that master, drawing 12-30V DC or 12-16V AC to switch an external signaling device when a door station calls in. The Securitron RB-4 is a general-purpose relay board in the RB-4 series, not an intercom accessory tied to an Aiphone chime output. Use the RY-ES when the trigger is an Aiphone JP, JO, JK, JF, KB, AX, NIM, DB or IE master station; use a general relay board when you are switching a load from an access control output instead.

The Aiphone RY-ES follows the master station chime output; it energizes an external signaling device when the door station calls in and its contacts are rated 125V AC 1.0A / 30V DC 1.0A. It is not a timing device. If the job needs an adjustable timed output, the Securitron TM-2 Time Master II is a multi-function timer built for that role. Many installers use both - the RY-ES to pick off the Aiphone call signal, a timer downstream to hold the output for a set interval.

Contact rating is 1.0A at 125V AC and 1.0A at 30V DC. That is enough to switch a small horn, strobe, or bell directly, but anything heavier should be handled by a contactor or a larger relay board driven off the RY-ES contact rather than wired straight through it.

The RY-ES is a single-purpose call signaling relay tied to an Aiphone master station's chime output, so it won't do timing or multi-point logic. For those jobs ZenSupply carries the Securitron TM-2 Time Master II multi-function timer for timed outputs, and the Securitron RB-4 relay board or RLP relay logic pack when you need additional switching or logic in an access control circuit.

The Aiphone RY-ES is single-purpose: it sits on the chime output of an Aiphone master station on the JP, JO, JK, JF, KB, AX, NIM, DB or IE systems (excluding IE-8MD) and closes a contact rated 125V AC 1.0A / 30V DC 1.0A to fire a remote bell, strobe or horn, taking its power from the master. The Securitron RLP is a relay logic pack in the RLP series, intended for building switching logic in an access control circuit rather than for extending an intercom call. Pick the RY-ES when the source of the signal is the Aiphone master itself.

Not directly. The RY-ES contacts are rated 125V AC 1.0A and 30V DC 1.0A, and the relay draws its own power from the Aiphone master station (standby 10mA DC / 15mA AC, max 60mA DC / 70mA AC). For a heavier signaling load, use the RY-ES as the pilot and switch the load through a separate relay board such as the Securitron RB-4, or through a Securitron RLP relay logic pack, so the larger current never passes through the Aiphone contacts.

It is classed as commercial door hardware, and that matches the use case: tying an entry intercom call into a warehouse horn, a back office buzzer, or a strobe in a noisy area. It is a low-current electronic accessory that mounts near the master station and draws its power from it.

The RY-ES is a single model with no finish, voltage, or configuration options to specify. Quantity is driven by how many master stations you want to extend the call from, since each relay ties to one master station's chime output.
