Wireless Door Window Alarm Sensor with Magnetic Sensor, 4 Modes & 110dB

Wireless Door and Window Alarm with Four Modes This wireless magnetic alarm offers reliable protection for your home, office, garage or shop. Designed to fit any door or window, it detects when a door or window is opened and responds with a loud 110 dB siren to deter intruders. The unit operates in four switchable modes, making it a versatile addition to your home security setup. Four Switchable Modes After the alarm has been switched off for a while, close the door or bring the magnetic strip near the main unit. Once the unit has started up after 15 seconds, turn the power switch several times to cycle through the four functions, each confirmed by a distinct prompt tone. One turn selects the alarm mode, two turns select the continuous alarm mode, three turns select the door-closing reminder mode, and four turns select the doorbell mode. This flexibility lets you choose the right setting for each entry point in your home. Simple Installation and Reliable Detection The alarm attaches easily to any fridge, freezer or door using the adhesive tape provided. For best performance, keep the gap between the alarm sensor and the magnet within 2.3 cm. The reliable magnetic sensor triggers the alarm immediately when a door or window is opened, helping to alert you to unauthorised entry and improve your home security in any environment. Low Battery Warning and Long Battery Life When battery power runs low, the alarm sounds briefly to remind you to replace the battery. The unit can stand for around a year on a single battery, and one battery is included as a gift so you can use the alarm straight away after receiving it.
