HO Signal System
In 2006, answering increased demand by
discriminating modelers, Atlas is introducing its HO Scale Signal
Systems, offered in three versions, each complete with a signal
relay shed for static display. The signals will be offered as a
single target, double target, bi-directional targets and single
targets in a four pack. The Atlas Model RR Signal System features
true scale dimensions and details, and includes circuitry for North
American prototype operation. These signals can be used as a
stand-alone accessory, or connected to one another for complete
dynamic integration. They are the perfect compliment to Atlas?

Frequently Asked Questions
Q. What do you need to get started?
A. The number of signals and detector boards you use depends on the
size and complexity of your layout. The easiest way to get started
is to use the all-in-one pack Type G Single Target Kit, #236 (HO
Scale) #2236 (N Scale). More information is available in the manual
that comes with the signals.
Q. What does the signal control board (SCB) and the
block detector board (BDB) do?
A. The signal control board and block detector board comprise the
electronic ?brain? of the system. The block detector senses current
flow in the block. Installed under the table or mounted under your
layout, the control and detector boards are capable of four broad
modes of operating options. They control the input from the block
detector board and output to the signal target head.
Q. How does the stand-alone signal operation
A. The Red and Green are controlled by occupancy. The Yellow is the
controlled timed feature in this mode of operation.
Q. Where do I install the signal?
A. The signal is normally placed at the entrance to a block. (A
block is any section of track that is electrically isolated from
the rest of the layout.)
Q. How do I add integrated signal
A. To add integrated signal operation of two or more signals, plug
in the modular Atlas Signal Cable - Item #s 230 (7?), 231 (15?)
& 232, (25?), in the length that is appropriate to your block
size. Next, plug the cable into a jack, (RJ-11), on the first
signal board and into the jack, (RJ11), on the other signal board.
Jack 3, (RJ12), is where the signal plugs in.
Q. How does the integrated signal operation
A. Installation of the Integrated Signal Cable automatically
disengages the timed Yellow feature of the stand-alone signal. All
aspects are now under full control of the blocks and signals in
front of and behind your train. (See manual for details.)
