The burglar alarm system comes fully programmed, requiring no additional programming. Simply open each sensor (excluding the remote control) and remove the paper tab near the battery to power up the unit. Install the sensors in desired locations and plug in the siren horn using a 110 V to 220 V AC adapter. Use the remote key fob to arm or disarm the system, with the alarm horn beeping to indicate the status.

In the event of false alarms, reset the system to factory settings and follow the operation guide for re-setup. Alternatively, replace the batteries in the sensors. The siren host alarm does not flash and the alarm time and volume cannot be adjusted. The alarm will sound immediately when a sensor is triggered and will continue for about 2 minutes in the event of no disarmament.

For increased volume, additional black horns can be added to work with the same set of wireless sensors. The alarm system supports multiple accessories from the KERUI brand, including door/window sensors, remote controls, and live sound alarm hosts. The 720P wifi camera provides real-time monitoring and two-way audio.

This simple, affordable alarm system is suitable for sheds, garages, shops, and homes. The motion sensor detects movement within a range of 19 to 26 feet and can be adjusted to avoid false alarms. Similarly, the door sensor triggers the alarm when a door or window is opened wider than 1mm.

The DIY expandable alarm system supports up to 30 wireless detectors and offers complete protection for various settings. In the event of an emergency, the remote control includes an SOS button to trigger the alarm and alert others for help. Customer service is available for any technical issues or customization needs.
