	Style A Decoder

	Construction	Plug-in circuit board

	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.

	Relay Response	Field-changeable to operate the relays in the following sequence, by removing
		diodes D3, D4, and D12.
		Ø 3 pulses closes the 3-pulse relay.
		Ø 5 pulses closes the 3- and 5-pulse relays.
		Ø 7 pulses closes the 3-, 5-, and 7-pulse relays.

	Timer	Holds the relay(s) closed for 15 minutes. In fast test mode, timer releases relays
		after 20 seconds.
