No.: 15.231(a) Test Performed By: Chris Maidens Date of Test: July 29, 2004 Minimum Standard: 15.231(a) Continuous transmissions such as voice, video or data transmissions are not permitted. 15.231(a)(1) A manually operated transmitter shall employ a switch that will automatically deactivate the transmitter within not more than 5 seconds after being released. 15.231(a)(2) A transmitter activated automatically shall cease transmission within 5 seconds of activation. 15.231(a)(3) Periodic transmissions at regular pre-determined intervals are not permitted. However polling or supervisory transmissions to determine system integrity of transmitters used in security or safety applications are allowed if the periodic rate of transmission does not exceed one transmission of not more than one second duration per hour for each transmitter. 15.231(a)(4) Intentional radiators, which are employed for radio control purposes during emergencies involving fire, security of goods, and safety of life, when activated to signal an alarm, may operate during the pendency of the alarm. Test Results: Complied Test Data: Compliance was determined by verification of technical specifications and a functional test on the equipment. Page 6 of 16
