About this product

Boosts weak 433MHz sensor signals to help prevent missed alerts.

Range depends on layout and interference (walls/metal/electronics). We’ll help you place it for best results.

When your alarm sensors feel “too far”, this little booster brings them back to life.
More signal. More coverage. More peace of mind.

A 433MHz signal booster that helps your GT10 alarm sensors communicate more reliably.

Why You'll Love It:

Stronger sensor-to-panel signal – helps reduce “missed triggers” caused by distance or weak coverage.

Extends coverage in bigger homes – ideal for double-storey homes, long passages, garages, and outbuildings.

Simple placement – power it on and place it between the alarm panel and the far sensors for best results.

Supports multiple sensors – can work with up to 30 detectors (practical setup depends on your system layout).

Cleaner, more reliable protection – helps your system stay responsive when sensors are on the edge of range.

What You Need to Know:

  • Power: DC 12V (uses an adapter)

  • Range help: receives up to ~100m line-of-sight, re-transmits up to ~500m line-of-sight

  • Capacity: can support up to 30 wireless detectors

  • Size/weight: 16 × 9 × 8 cm, about 200 g

Compatibility (Important)

  • Works with 433MHz wireless alarm systems that support common pairing protocols (GT10 accessory ecosystem).

  • This is a signal repeater for alarm sensors (not a WiFi extender).

  • Not “pet-immune” by itself - pet immunity depends on the PIR sensor you choose (door sensors don’t care about pets).

  • Local support + setup help available (we can help you place it and test signal strength).

Mini FAQ

Q: What does a signal repeater actually do?
A: It boosts and relays weak 433MHz sensor signals so your alarm panel receives triggers more reliably.

Q: Where should I place it?
A: Place it between your far sensors and the alarm panel (not right next to the panel).

Q: Will it work through walls?
A: It helps, but walls/metal can reduce range. Best results come from smart placement and testing.

Q: Is this a WiFi extender?
A: No - it boosts 433MHz alarm sensor signals, not WiFi.

Q: How many sensors can it support?
A: Up to 30 detectors in total (practical limit depends on your layout and zone planning).
