Touch‑Sensitive Bottom Safety Edge
A touch‑sensitive bottom safety edge is one of the most advanced safety upgrades you can add to your garage door system. Unlike standard photo‑eye sensors that require an object to break an infrared beam, a touch‑sensitive edge detects even the slightest contact — reversing the door before any pressure is applied. This makes it an ideal accessory for families, pets, and anyone who wants maximum protection.
What Is a Touch‑Sensitive Bottom Safety Edge?
This accessory replaces the standard bottom seal with a pressure‑sensitive or touch‑sensitive strip. When the door begins to close, the edge continuously monitors for resistance or contact. If it detects anything — even a light touch — it immediately signals the opener to reverse.
- Reverses the door instantly
- Activates before pressure is applied
- Works even if photo‑eyes are misaligned or blocked
- Adds a second layer of safety to your system
How It Works
The safety edge contains a sensor that runs the full width of the door. When the door lowers and the edge touches an object, the sensor sends a signal to the opener to stop and reverse.
Two common types:
- Electric (wired) safety edge: Uses a pressure‑sensitive switch
- Airwave safety edge: Uses a hollow air tube that triggers a switch when compressed
Both types provide fast, reliable protection.
Why Add a Touch‑Sensitive Safety Edge?
This accessory offers benefits beyond standard safety sensors:
- Enhanced safety: Reverses before the door applies force
- Redundancy: Works even if photo‑eyes fail
- Better protection for pets and children
- Ideal for uneven floors: Where photo‑eyes may not detect low objects
- Commercial‑grade safety for residential doors
Who Should Consider This Upgrade?
- Families with small children or pets
- Homes with uneven garage floors
- Garages used as workshops or hobby spaces
- Anyone wanting the highest level of safety
- Homeowners with heavy or oversized doors
Installation Overview
Installing a touch‑sensitive safety edge typically involves:
- Removing the existing bottom seal
- Installing the new sensor-equipped bottom edge
- Running a low‑voltage wire to the opener
- Programming and testing the reversing function
Maintenance Tips
- Inspect the seal every 6 months
- Check wiring for wear or damage
- Test the reversing function regularly
- Replace the seal if it becomes cracked or brittle
