Door/window alarm Battery-operated | 3x AAA/LR03 | 85 dB | White This alarm device is activated by entering a four-digit PIN code on the keypad on the front of the device. The system has three operating modes: 1. normally the alarm device is in "Absent" mode, which means that an input and output delay is activated. 2. it is also possible to switch the alarm device to "At home" mode. It then activates an output delay of 15 seconds and an input delay of 0 seconds. 3. in "Sound" mode, a tone sounds immediately when the alarm is triggered. In addition, by activating the panic mode, a loud alarm sounds immediately to attract attention. "Panic" can be activated while the alarm device is in "Sound", "Away", "At home" mode or even deactivated. The alarm is powered by 3 LR03 (AAA) alkaline batteries and has an optional AC/DC adapter connection for a 2.5 mm mono jack adapter plug (4.5 V DC) to ensure that the power supply is never interrupted. https://elecena.pl/product/29311008/alrmd30wt-door-window-alarm 2025-08-27 https://elecena.pl/product/29311008/alrmd30wt-door-window-alarm 2025-12-16
