1. Introduction
The Optex RC-20U 3 Channel Receiver Chimebox with Relay is designed to enhance your Optex Wireless 2000 and 1000 systems by providing audible alerts for perimeter breaches. This receiver can differentiate between up to nine transmitters, categorizing them into three distinct groups, each with a unique chime tone. It also features a Form C relay for integration with other devices.
Key Features:
- Accepts up to 9 transmitters, identifying each group of 3 with a different chime tone.
- Operates with an included 9VDC adapter.
- Designed for versatile wall-mount or table-mount installation.
- Includes a Form C relay for activating external devices (50V AC 1A max. or 24V DC 1A max.).

3. Setup
3.1 Powering the Unit
- Connect the small barrel connector of the 9VDC power adapter to the power input jack on the Optex RC-20U receiver.
- Plug the 9VDC power adapter into a standard electrical outlet. The receiver will power on, indicated by an LED light (if present).
3.2 Mounting the Receiver
The RC-20U receiver can be placed on a flat surface or mounted on a wall.
- Table-Mount: Place the receiver on a stable, flat surface in a central location within range of your transmitters. Ensure it is not obstructed by large metal objects.
- Wall-Mount: Use appropriate screws (not included) to secure the receiver to a wall. Refer to the receiver's back panel for keyhole slots. Ensure the antenna is oriented for optimal signal reception.
3.3 Pairing Transmitters
The RC-20U receiver can be paired with up to nine Optex wireless transmitters, organized into three groups of three, each triggering a unique chime tone. Refer to your specific Optex transmitter's manual for its pairing mode instructions.
- Ensure the RC-20U receiver is powered on.
- Locate the programming button or switch on the RC-20U receiver (consult the device for exact location, often a small button or dip switch).
- Activate the pairing mode on the RC-20U receiver according to its specific instructions (e.g., press and hold a button until an indicator light flashes).
- Within the pairing window, activate the desired transmitter (e.g., trigger its sensor). The receiver should acknowledge the pairing with a beep or flash.
- Repeat for additional transmitters. The receiver will automatically assign transmitters to groups and their corresponding chime tones as they are paired.
- Test each paired transmitter to confirm it triggers the correct chime tone on the receiver.
4. Operating Instructions
4.1 Chime Tones
When a paired transmitter detects activity, the RC-20U receiver will emit an audible chime. The receiver distinguishes between three groups of transmitters, each assigned a unique chime tone. This allows users to identify which area or zone has been triggered without needing to visually check the unit.
4.2 Relay Function
The RC-20U features a Form C relay output, which can be used to activate external devices such as lights, sirens, or other security systems. This relay activates when any paired transmitter triggers the receiver.
- Connection: Connect the relay output terminals on the RC-20U to the input terminals of the external device. Ensure correct polarity and voltage requirements.
- Specifications: The relay supports a maximum of 50V AC at 1A or 24V DC at 1A. Do not exceed these ratings to prevent damage to the receiver or connected equipment.
- Configuration: Consult the RC-20U's specific wiring diagram and the external device's manual for detailed connection and configuration instructions.
5. Maintenance
To ensure optimal performance and longevity of your Optex RC-20U receiver, follow these simple maintenance guidelines:
- Cleaning: Wipe the receiver with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing.
- Environment: Keep the receiver in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.
- Power Supply: Only use the provided 9VDC power adapter or a compatible replacement specified by Optex.
- Antenna: Ensure the antenna is not bent or damaged, as this can affect wireless reception.
6. Troubleshooting
If you encounter issues with your RC-20U receiver, refer to the following table for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Receiver does not power on. | Power adapter not connected or faulty; power outlet not active. | Ensure power adapter is securely plugged into receiver and a working outlet. Test outlet with another device. |
| No chime when transmitter is triggered. | Transmitter not paired; transmitter out of range; low battery in transmitter; interference. | Verify transmitter is paired (Section 3.3). Move receiver closer to transmitter. Check transmitter battery. Reduce potential sources of interference (e.g., large metal objects, other wireless devices). |
| Chime tone is incorrect for a specific zone. | Transmitter paired to the wrong group. | Re-pair the transmitter, ensuring it is assigned to the desired group during the pairing process. |
| Relay does not activate. | Incorrect wiring; external device fault; relay overloaded. | Check relay wiring (Section 4.2). Verify external device is functional. Ensure relay load does not exceed 50V AC 1A or 24V DC 1A. |
| Short detection range. | Obstructions; antenna position; environmental factors. | Relocate receiver or transmitter to minimize obstructions. Adjust antenna for optimal reception. Consider environmental factors like thick walls or metal structures. |
