Wireless Interface RAD ISM 900 SET UD ANT One way point to point Monitoring or Control User Manual Figure 1 RAD ISM 900 SET UD ANT Notice These devices must be wired in accordance with Class I Division 2 wiring methods as described in the National Electric Code Article 501 4 b or the authority having jurisdiction Transmitter unit is to be used with a purely resistive antenna when installed in Class I Division 2 areas DOO GD GD OGD INSPIRING INNOVATIONS The RAD ISM 900 SET UD ANT is Frequency Hopping Spread Spectrum radio designed for the professional installation and integration with other products When installed with an approved antenna and cable the system integrator needs to make sure that the unit s FCC label or a copy of the FCC label is clearly visible on the outside of the integrated product The RAD ISM 900 SET UD ANT is approved within the 902 to 928 MHz ISM Band under Part 15 of the FCC Rules and Regulations Frequency Hopping Spread Spectrum technology was originally developed by the U S military to prevent interference or interception of radio transmissions on the battlefield Frequency hopping devices concentrate their full power into a very narrow signal and randomly hop from one frequency to another within a designated frequency band If they encounter interference on a particular frequency the devices error check the affected data hop to another point on the spectrum and resume communica2.
