Alpha RE-DCE Dry Contact Emitter

The Alpha RE-DCE Dry Contact Emitter provides an interface between compatible Alpha motor systems and external building automation or control equipment.

The single-channel emitter plugs into a power point for permanent 240V 50Hz power and can be connected to relays or suitable switches within an external control system.

Four control wires are provided: Common, Up, Stop and Down. When the common wire makes contact with one of the control wires, the RE-DCE wirelessly transmits the corresponding command to assigned Alpha WSER Series motors or compatible remote receivers.

This allows compatible Alpha motors to be operated through a wide variety of external control systems, including building management systems, automation equipment, push buttons and key-turn switches, while retaining compatible Alpha remote-control operation.

The RE-DCE is not intended for initial motor setup or programming. Alpha specifies that motor setup should be completed using a standard remote, after which the RE-DCE can be separately assigned to the motor for additional control options.

Specifications

Important Installation Information

The RE-DCE should be connected only to relays or switches that make contact while pressed or activated and automatically release afterwards.

Do not use rotary switches or switches that lock into position. If contact remains closed, the RE-DCE will continue transmitting the corresponding signal for as long as contact is maintained, which Alpha warns could produce unwanted results.

Motor setup should be completed using a standard compatible remote. The RE-DCE can then be assigned separately to provide additional control through the external system.

FAQ

1. What does the Alpha RE-DCE do?

The RE-DCE allows compatible Alpha motors and remote receivers to receive wireless commands triggered by an external control system, relay or suitable switch.

2. Which Alpha motors can the RE-DCE control?

Alpha specifies that commands can be transmitted to assigned WSER Series motors or remote receivers.

3. What control wires does the RE-DCE have?

It has four control wires: Common, Up, Stop and Down.

4. Can the RE-DCE integrate Alpha motors with a building management system?

Yes. Alpha specifically designed it to allow compatible motors to be operated through systems such as building management systems and automation equipment.

5. Can I use the RE-DCE to initially set up a motor?

No. Alpha states that it is not practical for motor setup. Initial setup should be performed with a standard remote before assigning the RE-DCE separately.

6. Can I use a locking or rotary switch?

No. Alpha advises using contacts that automatically release. A locking switch could cause the RE-DCE to continuously transmit a command while the contact remains closed.

7. What frequency does the RE-DCE use?

It operates on 433.92MHz using rolling-code technology.
