Types of Installations
Model RC-1T5A is ideally suited for installations such as:
Runway Edge Lighting
ALSF 1 and 2
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 receiver is of combination field-effect transistor and integrated-circuit design. The sensitivity is adjustable from 1 microvolt to 30 microvolts as desired by the user,permitting a control range of 1 to 20 miles. Receivers are shipped normally adjusted to a sensitivity of 10 microvolts. The unit is designed to operate from 120 volt ±20% 50-60 HZ single phase power.
3.0 THEORY OF OPERATION:
The system is activated upon receiving a series of pulses of R.F. energy where each succeeding pulse follows the preceding pulse by not more than one second. 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 anytime, reinitiating the 15 minute "run" cycle. Operating time may be selected in 15 minute intervals up to 1 hour by setting switches on the Timer Board.
The solid state receiver-controller is composed of five printed circuit cards which include the regulated power supply and maintenance test oscillator. The following describes the theory of operation for each of the receiver-controller basic elements.
During system test, the 15 minute timing cycle may be terminated by pressing the ‘Timeout’ switch on the base assembly. In the event of power failure, the system will resume operation in the last commanded mode.
