Door Alarm with Key Switch DG6: Ensures no one enters unnoticed. Effective alarm system: If an unauthorized guest attempts to break into your home, they will likely only make it to the door. Once the door is opened, the magnetic contact immediately triggers a deafening noise. While this may not prevent a burglar from opening the door, it serves as a deterrent and draws attention. Easy installation, great benefit: The door alarm is suitable for both left and right-opening doors. It can be conveniently armed and disarmed using a key and can be easily mounted on the inside of the house with the included screws or adhesive strips. An added advantage: Two operating modes can be selected; in addition to immediate alarm, a 15-second delay alarm can also be set. This way, you won't accidentally trigger the alarm when you come home. The alarm can only be turned off with the included keys (delivery includes 2 keys). Made of ABS plastic with a 95 dB(A) alarm sound and a maximum alarm duration of 90 seconds.
