Response
Receiver pulses. Decoder remains non-responsive unless three or more pulses are
received in a 5-second interval.  Only one relay stays powered, determined by the
number of pulses sent to the receiver:
Ø  3 pulses closes the 3-pulse relay.
Ø  5 pulses closes the 5-pulse relay and opens the 3-pulse relay.
Ø  7 pulses closes the 7-pulse relay and opens the 5-pulse relay.
Decoder does not respond to signal elements of less than 50 milliseconds and does
not require signal elements of more than 100 milliseconds.
