When an in-building radio system is required, and upon completion of installation, it will be the building owner's responsibility to have the radio system tested to ensure that two-way coverage on each floor of the building is a minimum of 95%. Each floor of the building shall be divided into a grid of approximately 20 equal areas. A maximum of one area will be allowed to fail the test. If more than one area fails the test, the building owner shall have the system altered to meet the ninety-five-percent-coverage requirement. The test shall be conducted using a hand-held-type Washington Township portable, worn at the hip, with the use of standard lapel speaker/microphone, talking through the Washington Township police radio communications system. A spot located approximately in the center of a grid area will be selected for the test, then the radio will be keyed to verify two-way communications to and from the outside of the building through the Washington Township Police Department communications system. Once the spot has been selected, prospecting for a better spot within the grid area will not be permitted.
