The DOS Tyxal+ is a ground contact opening detector that can be used to secure a large gate (garage door, shed door, etc.) in your home. The detector is fixed with screws, with one part on the ground and the other on the door leaf. It is connected wirelessly to the control panel and is powered by the battery provided for up to 10 years (depending on use). To work properly, the detector must be connected to a CS 8000 Tyxal + control panel. The opening detector is protected against sabotage and automatically triggers the alarm if someone tampers with the detector without authorization.
