Using Wireless Sensors on Metal Doors
including patio doors, windows, & metal-frame openings
Wireless door sensor operation can be adversely affected when affixed to a metal door or metal-frame opening such as a patio door or window. Prior to mounting the unit, the sensor may operate flawlessly. But once applied to the metal surface, there may be little, if any, detected signal at the controller / receiver. Two possible solution options are recommended. (Trial-and-error testing may be required to determine suitable results.)
Hint: The receiving antenna must be properly located for best reception. It should be positioned at ceiling height and oriented vertically. Ensure 3 ft. separation (minimum) from HVAC equipment, appliances, electrical equipment, conduits, plumbing, water heater, metal studs, and electronic devices. If your installation does not meet these requirements, you should promptly relocate the antenna.
