TC5126W Wireless Fire Alarm Control Panel — Buyer FAQ

4. Installation & Debugging

Q12. How do I register a wireless detector to the panel?

Typical registration procedure:

Enter the wireless registration menu on the panel.

Press the network button on the detector 3 times (green LED flashes 3 times).

The panel automatically assigns an address to the device.

For large projects, batch registration or pre-addressing may be possible depending on firmware version. Contact us for the latest commissioning guide.

Q13. How do I check signal strength during installation?

Press the network button on the device once. The panel will display the R/T signal strength value (0–130). Lower values indicate a stronger signal. As a rule of thumb, a value below 100 is considered stable. If the value is higher, relocate the device or add a repeater.

Q14. How many repeaters can I use?

Each wireless loop supports up to 8 repeaters, with a maximum of 5 repeaters per floor. Plan repeater placement carefully to avoid signal overlap and address conflicts.

Q15. What is the best mounting position for wireless detectors?

Detectors should be ceiling-mounted, away from metal structures, large electrical equipment, and RF interference sources. Avoid mounting on walls or inside metal enclosures, as this significantly reduces wireless range.

5. Power & Battery

Q16. What is the main power supply?

The panel operates on AC 220V (or regional variant) with dual 12V/3.3Ah sealed lead-acid backup batteries.

Q17. How long do detector batteries last?

Battery life typically ranges from 1 to 3 years, depending on communication frequency and configured power level. Higher power levels increase range but reduce battery life.

Q18. Can I extend battery life?

Yes. You can set the device to a lower power mode, such as Power Level Lv4. This reduces power consumption but extends the fault reporting interval to up to 15 hours. This is a trade-off between battery life and fault detection speed.

Q19. What does a "Main Power Fault" or "Backup Battery Fault" mean?

Main Power Fault: Usually caused by a blown AC fuse, loose wiring, or power supply failure.

Backup Battery Fault: Usually caused by disconnected batteries, low battery voltage (below 22V), or aged batteries.

These are basic troubleshooting items and can often be resolved on site without returning the panel.

6. Troubleshooting & After-Sales

Q20. Why does a detector show "Offline" on the panel?

Common causes include:

Dead or poorly connected battery

Device too far from the panel or repeater

RF interference from nearby equipment

Duplicate device address

Incorrect mounting location

Check the panel event log to identify the affected loop and address, then inspect the device and signal strength.

Q21. How often should the system be tested?

We recommend a functional test every 6 months and a full system inspection annually, or as required by local fire regulations.

Q22. What is the warranty period?

Warranty period is one year. Free technical support for all life time.
