Product Information

About this item

• [Product Descriptiont] This set includes door chimes + doorbell. Buying as a set is very convenient: the receiver can connect to both the sensor and the button simultaneously—no need to buy an extra receiver(simple, unlike buying a doorbell and door chimes separately, which would require two receivers). Plus, you can set different ringtones for the door chime and doorbell.
• [Upgraded IP55 Waterproof Button] Rated IP55 waterproof and -22°F to 158°F resistant. This doorbell chime (with button) and door sensor chime (with receiver + sensor) work together: press the button, the receiver alerts instantly.
• [Upgraded Low-Power Long-Life Battery] Low-power design lasts up to 1 year with 30,000 triggers. This door alarm sensor comes with one CR2450 battery.
• [Alarm & Chime Modes] Use door alarms for instant alerts when children or elders wander out or when intruders enter. This alarm mode is ideal for protecting your home and children. Or choose a door chime for business to welcome customers as they enter—great for shops, offices, and stores.
• [Plug-and-Play Installation] Sensor and receiver are pre-paired. Just plug the receiver into an outlet, peel and stick the sensor/button tape, and attach the sensor/button to your door or window. This door entry chime installs in seconds with no wiring required.
• [500ft Wireless Range & Expandable Pairing]: This window and door alarms for home offers a 500ft open‑air range (keep within 100ft indoors due to obstacles). Avoid metal doors, microwaves, TVs, and induction cookers as they may interfere with the signal. One receiver supports up to 30 sensors.
• [Mute to 110dB] Choose from 55 tones with 5 volume levels up to 110dB—loud enough to serve as an open door alarm heard anywhere. Need quiet? Set to mute for discreet alerts.
