NEDIS ALRMD30WT Window sensor White

This alarm is activated by entering a four-digit PIN code via the keypad on the front. The system has three operating modes. The alarm mode is available in two settings. 1. Normally, the 'Away' mode is set, which means an entry and exit delay is activated. 2. It is also possible to set the 'Home' mode. This activates a 15-second exit delay and a 0-second entry delay. 3. In 'Doorbell' mode, a doorbell will sound immediately when the alarm is triggered. Furthermore, by activating the panic mode, you will immediately hear a loud alarm to attract attention. You can activate 'Panic' in 'Doorbell', 'Away', or 'Home' mode, or even when the alarm is off. The alarm is powered by 3 LR03 (AAA) alkaline batteries and has an optional AC/DC adapter connection for a 4.5 V DC - 2.5 mm mono jack adapter plug. This ensures the alarm always has power.
