The DO BL Tyxal+ is an opening detector that can be used to secure doors and/or windows. It is connected wirelessly to the alarm control panel and is powered by a battery that can last up to 10 years. In the event of a break-in, the detector sends a signal to the control panel, which then sounds the siren (up to 109 decibels, depending on the setting). The opening detector is protected against sabotage and automatically triggers the alarm if someone tampers with the siren without authorization.
