Page 3: Introduction
• Integrated Operation - Each signal is connected together and the Red-Yellow Green aspects are controlled by the blocks and signals in front of and behind your train. Hook-up between signals is accomplished easily with the Atlas O Signal Cable (Items #6937-6939), pre-packaged in lengths of 7', 15' and 25'. - Page 4 • Complex Signaling (in conjunction with the signals and signal boards offered by Custom Signals, Inc.) - The Atlas O Signal System has been designed to be fully compatible with the products offered by Custom Signals, Inc., one of the hobby's premier custom signal builders.

1. J1- (Jack 1) - J1 is used for multiple inte- grated installations only. In integrated installa- tions, J1 is plugged into J2 of the following board. Atlas O carries a variety of modular con- nectors in 7',15', and 25' lengths, (Item #'s 6937-6939). See page 11 for further explana- tion of integrated installation. - Page 6 5. J5- (Jack 5) - J5 is a screw-type connection strip used for input/output connections. a. TM - TM is the turnout module connection. It can be connected to either the Atlas O switch signal control board for correct output to block signal control board #6930, or to Custom Signals turnout signal control board.

9. LED1 - LED 1 is used to indicate whether the correct power is going to the circuit board. If lit, it is correct. *(Please note-Atlas O recommends their readily available brand of 20 gauge, multi-stranded copper wire that comes in a variety of colors, Item#'s 315-#319. -

#7935 DEFINITIONS 2-RAIL DETECTOR BOARD PWR IN - Power from transformer or power supply TO TRACK - Wire to insulated rail used in “Block” LED 1 - Used for visual indication of “Block” occupancy. Will be lit whenever “Block” is occupied PWR - Circuit board power 6-22VAC or DC DET - Detector output connects to “DIN”... - Page 9 The signal board will be located either within the silver shed that comes with both the single and four pack kits, (Item #’s 7930 and #7934) or it may be mounted under the table with the sup- plied bracket. The shed can be located on either side of the track in relation to the signal. They should, however, be in close proximity to one another as determined by the length of the signal wire.
- Page 10 Drill a 5/8” hole under the middle of relay shed location. Run the red and black power wires from the J4 terminal strip, (PWR) of the signal board to power leads of the unplugged source of power, (6- 22VAC or DC power pack). Create an insulated rail section of track.

Page 11: How To Make An Insulated Rail Section
HOW TO MAKE AN INSULATED RAIL SECTION USING ATLAS O TRACK For best results when using insulated track rails in conjunction with the detector, it is recom- mended to use a minimum of three 10" sections, (Item #7050), or more. As shown in the dia- gram below, remove two nickel silver rail joiners, (Item #7091), from one of the running rails and replace with plastic insulated rail joiners, (Item #7093). -
Page 12: Installing The 2Nd Signal: Adding The Multiple Integration Feature
SIGNALS To add integrated signal operation of two or more signals, you need to plug in the modular Atlas O Signal Cable (Items #6937- 6939) in the length that is appro- priate for your block size. The cable is available in lengths of 7’, 15’ and 25’. -
Page 14: Approach Mode And Bi-Directional Signaling With Examples
APPROACH MODE On some prototype railroads, the signals remain unlit until a train is approaching. The Atlas O Signal System has the provisions to duplicate this operation. In the diagram below, Signal #1, which is connected to Block #2, will remain dark until a train enters Block #1. The signal will then light green for the approaching train. - Page 15 TYPICAL INTEGRATED integrated wiring ONE-DIRECTIONAL SIGNAL SET-UP scheme, and all of the signals are connected with the Atlas O Signal Cables, approach lighting is very easy.

Page 17: Setting The Jumper Plugs
SETTING THE JUMPER PLUGS The jumper plugs are found on the right hand side of the signal board, location JP1 and JP2. The default, (as delivered) setting has both jumpers partially covered. Basic stand-alone and integrated operation will not require movement of these plugs. The caps are moved into different positions if approach mode, search light, or more advanced optional features are wanted. -
Page 18: How To Use The Dout Feature
HOW TO USE THE DOUT OPTIONAL FEATURE DOUT stands for detector output which is located on the lower left hand side J5 terminal strip of the sig- nal control circuit board, (see diagram below). It is used to connect an auxiliary piece of equipment such as a control panel LED or a relay. -
