Signal Planning
Plan Receiver Placement Before Choosing A Kit
Use the 1300 ft / 400 m range as an open-area reference, then think about walls, floors and the rooms where the chime or LED alert must be noticed.
Open-Area Reference
1300 ft / 400 m is measured as an open-area transmission reference, not a whole-home coverage guarantee.
Walls And Floors Matter
Concrete, thick walls, metal doors, appliances and other wireless interference can reduce real signal performance.
Choose Listening Zones
Add plug-in receivers for upstairs rooms, offices, garages or back rooms where one chime may be missed.
Test Before Final Fixing
Try the button and receiver positions before final mounting, then adjust placement if the alert is weak.
Reference layout sizes are planning guides. Final performance depends on building materials, distance, receiver position and local interference.

Questions Buyers Ask
How should I choose receiver count?
Choose receivers by the areas where someone should notice the chime or LED alert, not only by the total size of the home.
Will this cover the whole home?
The 1300 ft / 400 m range refers to open-area transmission. Walls, metal doors, distance, appliances and other wireless interference can reduce real signal performance.
