Mini FAQ
Q: Will this work with my alarm system?
A: It works with 433MHz wireless alarm systems that support door/window contact sensors (including GT10WC).
Q: What does it actually detect?
A: It detects open/close. When the door/window opens, the two pieces separate and the alarm system can trigger an alert.
Q: How close must the two pieces be?
A: Keep the gap 15mm or less when the door/window is closed for reliable detection.
Q: Can I put it on a sliding door?
A: Yes - as long as both parts can be mounted securely and stay aligned when closed.
Q: Does it need WiFi?
A: No. The sensor talks wirelessly to the alarm panel. WiFi/GSM alerts (if enabled) come from the panel, not the sensor.
