sensors and experience intermittent communication between sensor
package and console, try turning off these other devices for
troubleshooting purposes. You may need to relocate the transmitters or
receivers to avoid the interference and establish reliable communication.
The frequencies used by the sensors are one of (depending on your
location): 433, 868, or 915 MHz (915 MHz for United States).
• Line of Sight Rating. This device is rated at 300 feet line of sight (under
ideal circumstances; no interference, barriers or walls), but in most
real-world scenarios, including a wall or two, you will be able to go about
100 feet.
• Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding or metal wall framing. If you have such metal
barriers and experience communication problems, you must change the
placement of sensor package and or console.
The following table shows different transmission media and expected signal
strength reductions. Each “wall” or obstruction decreases the transmission
range by the factor shown below.
