The model RC-1T5A controller has been specifically designed to provide remote control of airport lighting systems which require three separate control functions. This control system will allow the approaching pilot to select high, medium or low levels of runway light intensity at his discretion. The RC-1T5A is enclosed in a weather-proof watertight housing and is conservatively designed for continuous outdoor unattended operation.
The design and construction are compliant with FAA specification L-854. The RC-1T5A receiver controller complies with FCC rules and regulations Part 15.
The system is activated upon receiving a series of pulses of R.F. energy within a 5 second period. Upon receipt of the third pulse K1 closes, at the fifth pulse, K2 closes, and upon receipt of the seventh pulse, K3 closes. NOTE: At any time in the sequence the pilot has the option of sending three, five or seven pulses to command the intensity level to his requirements.
The system will remain at the intensity level of the last command received.
The solid-state timer will continue to operate for 15 minutes after which it will cause the system to revert to the original "off" condition. The timer is reset by the receipt of any command at any time, reinitiating the 15 minute "run" cycle. Operating time may be selected in 15-minute intervals up to 1 hour by DIP switch settings on the Receiver Board.
During testing, the 15-minute operating period may be terminated by pressing the Reset Switch on the base assembly.
