Dimensions: Alarm unit: 43 x 85 x 15 mm, Magnetic sensor: 10 x 45 x 15 mm (W x H x D) Battery type: AAA/Micro Batteries included Weight: 10 g With the compact Time2Close window alarm, forgetting to leave windows or doors open is a thing of the past. Effectively prevent heat loss while heating or potential water damage during sudden storms. The alarm is versatile – for example, it can be used on refrigerators to prevent energy loss or on cabinets to deter unauthorized access. Select a timer with a duration of 5, 10, or 15 minutes and open or tilt the window. After the set time has elapsed, an increasing alarm tone will remind you to close the window. Or activate the optional 115 dB burglar alarm, which immediately attracts attention when the window or door is opened and effectively deters burglars. Operation is via the buttons on the alarm unit. A short tone and LED indicator lights confirm the selected mode. Installation is incredibly easy: no drilling or cables required, just an adhesive backing – ideal for rental properties as it won't damage window frames. Made of UV-resistant plastic, the device remains free of yellowing even after prolonged exposure to intense sunlight. Please note: The window alarm is for indoor use only. Important: Only one function can be used at a time – either the timer or the burglar alarm. ABUS August Bremicker Söhne KG, Altenhofer Weg 25, 58300 Wetter, Germany, info@abus.de
