Wireless door and window alarm system with a powerful 90 dB siren. 6-pack for homes, cars, sheds, caravans, and campers.

EASY INSTALLATION: No wiring required. Sensor brackets on both sides of the alarm simplify installation. Four LR44 batteries are included. MAGNETIC SENSOR: The magnetic sensor detects intrusions and protects your home or office. LOUD 90dB ALARM: If someone opens a door or window without authorization (and thus changes the location of the main and secondary rooms), a loud alarm sounds, prompting the intruder to leave the building and alerting the owner. ROBUST AND STABLE: Excellent environmental compatibility and stability; dustproof and insect-proof.
