2.4 Receiver Placement
Plug the receiver into a standard 120V AC outlet in a central location where the chime can be easily heard. Consider the long-range capabilities when choosing a location, as the signal can penetrate multiple obstacles.
2.5 Pairing Transmitters to Receiver Zones
The ERA-UTDCR receiver supports up to four zones, allowing different chimes for different entry points. You can pair an unlimited number of transmitters to each zone.
- Plug in the receiver.
- Press and hold the desired zone button (Zone 1, 2, 3, or 4) on the receiver until the zone indicator light flashes.
- Within 10 seconds, activate the transmitter (either press the push button or separate the magnetic contact).
- The receiver will chime, and the zone indicator light will stop flashing, confirming successful pairing.
- Repeat for additional transmitters or zones as needed.
3. Operating Instructions
Once set up, operating your ERA-UTDCR system is straightforward.
3.1 Activating the Chime
- Push Button Mode: Press the button on the transmitter. The receiver will sound the selected melody for the paired zone.
- Magnetic Contact Mode: When the magnetic contact separates (e.g., a door or window opens), the transmitter will activate, and the receiver will sound the selected melody for the paired zone.

Each zone on the receiver can be assigned one of 12 available melodies. Refer to the receiver's controls for melody selection specific to each zone.
3.4 Integrating 12VDC Accessories
The receiver includes four 12VDC outputs, one for each zone. These outputs can be used to connect external 12VDC accessories such as strobe lights, sirens, or buzzers. Consult the accessory's manual for specific wiring instructions and ensure compatibility with 12VDC output.
4. Maintenance
Regular maintenance ensures optimal performance and longevity of your ERA-UTDCR system.
4.1 Battery Replacement
The transmitter uses one CR123A battery. Replace the battery when the transmitter's indicator light no longer illuminates or if the signal range decreases significantly. Refer to Section 2.2 for battery installation steps.
4.2 Cleaning
Clean the exterior of the receiver and transmitter units with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the units.
4.3 Weather Resistance
The transmitter is designed to be heavy-duty and waterproof. However, for prolonged exposure to extreme weather conditions, consider additional protective measures to maximize its lifespan.
5. Troubleshooting
If you encounter issues with your ERA-UTDCR system, refer to the following common problems and solutions.
- No Chime Sound:
- Ensure the receiver is plugged into a working power outlet.
- Check the receiver's volume setting; it may be muted.
- Verify the transmitter battery is not depleted.
- Re-pair the transmitter to the desired zone (refer to Section 2.5).
- Reduced Signal Range:
- Replace the transmitter battery.
- Ensure there are no new large metal objects or dense structures placed between the transmitter and receiver that could interfere with the signal. While designed for long range and penetration, extreme obstructions can still impact performance.
- Relocate the receiver to a more central position.
- Magnetic Contact Not Triggering:
- Ensure the magnetic contact piece is aligned with the transmitter and within 1/2 inch when the door/window is closed.
- Check the transmitter battery.
- Re-pair the transmitter.
- False Alarms:
- For magnetic contacts, ensure the magnetic piece is securely mounted and does not shift, causing accidental separation.
- Check for environmental factors that might cause vibration or movement.
