The MDO GR Tyxal+ is a micro opening detector that can be used to secure doors or windows. It is connected wirelessly to the control panel and the battery supplied lasts up to 3 years depending on use. It is ideal for securing rarely used exits or windows. Its small size makes it very easy to integrate into your home. The detector is also available in white or caramel. In the event of a break-in, the detector sends a signal to the alarm center, which sounds the siren (up to 109 decibels depending on the setting).
