RC-1T4A HELIPORT LIGHTING $2275

   The model RC-1T4A controller has been specifically designed to provide remote control of heliport lighting systems which require two control functions. This control system will allow the approaching pilot to select either of two operating modes at his
discretion. The RC-1T4A is enclosed in a weather-proof water-tight housing and is conservatively designed for continuous outdoor unattended operation.

     The RC-1T4A 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. At the fifth pulse the first relay (K1) closes sending 120vac out of the Control 1 output. At the third pulse after closing Relay K1, the second
relay (K2) closes sending 120vac out of the Control 2 output . At the seventh pulse the relays open. NOTE: At any time in the sequence the pilot has the option of sending three, five or seven pulses to command the system 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.
