SANJIE Wireless Door Alarm 800 ft range 🔔
Description:
This compact wireless door alarm sensor chime helps you know when a door or window opens, offering audible alerts for home, office or shop entrances. The SANJIE unit combines a plug-in receiver and a magnetic sensor to provide up to 800FT/240M coverage according to the manufacturer, making it useful for monitoring short to medium distances with adjustable tones and volume.
Key Points
This set includes one plug-in receiver and one magnetic sensor that arrive pre-paired, so initial setup is straightforward. The sensor has an ON/OFF switch and uses double-sided adhesive for tool-free mounting; ensure the gap between sensor and magnet is less than 0.6 inch for reliable triggering. The chime offers 55 ringtones and five volume levels, including a mute option and a top volume of up to 110dB, which helps attract attention in noisy environments. LED indicators show activity and a memory function preserves your last selected tune after power is removed. For households with children or carers of people with cognitive impairment the alarm can serve as a discreet alert when doors are opened, and it can also work as a simple shop chime to tell you when customers enter the premises. 🔔

Usage Recommendations
Install the receiver in a central room socket so the chime is clearly audible where you spend most time. Place the sensor on doors or windows using the supplied adhesive; clean the surface first for best adhesion. If you need coverage through multiple internal walls, consider the potential for reduced range and test placement first, as thick walls or large metal structures may limit the effective distance. For retail use, choose a distinctive tone among the 55 options to separate customer alerts from household notifications. 🔍
Practical Notes
The package comes ready paired which simplifies first use, and the memory function is helpful if power outages are a concern. Consider that the single-sensor kit monitors one opening only; if you have several doors to cover you will need additional sensors. The audible output is loud enough for many domestic situations, but the maximum stated range and activation count are manufacturer figures and may vary with site conditions. ⚙️.
