Compact, wireless door/window contact sensor with a built-in 100DB siren and flashing light for immediate intrusion alerts. Designed to operate without a network connection, it supports arm, disarm and timer set functions and can provide real-time alarm notifications remotely. Installation is simple — no tools required: attach the units using 3M glue and press firmly. For reliable detection, align the two parts so the arrows face each other and keep the gap as small as possible (LESS THAN 10MM); the sensor should be positioned so it does not interfere with the door or window opening/closing. Verify proper alignment when checking open/close status to ensure accurate operation. Emits a 100DB sound plus light flash when triggered.
