Note:

In all cases, do not work or position equipment over an active traffic lane. Working

over active lanes presents a hazard to the installer and to travelers using the highway.

Follow local authorized procedures when installing the SAS-1 unit and any associated

components or subsystems.

Installation at the Traffic Monitoring Site Existing highway structures (light poles, sign bridges, overpasses, etc.) are suitable for mounting the SAS-1 for traffic monitoring. There is no need to mount the SAS-1 over any active lanes.
PAGE 4
To mount the SAS-1 on the highway structure, first attach the flange and tube assembly to the structure so that the mounting tube is approximately parallel to the flow of traffic. Secure the assembly using stainless steel strapping. Position the flange and tube assembly on the down road side of the highway structure if possible (Figure 3). This positioning is highly effective in keeping the SAS-1 out of sight of motorists and therefore, reduces the chance for vandalism.

The SAS-Junction Box (SAS-JB) is used to connect the short home run cable for one or more SAS-1 units to a single long home run cable for long runs to a roadside cabinet (Figure 5). For shorter cable runs to the roadside cabinet (less than 50 ft), the SAS-JB may not be needed. Route and secure the short home run cable from each SAS-1 unit along the highway structure to a position selected for mounting the SAS-Junction Box (SAS-JB).

home run cable. Do not let the black wires untwist from the corresponding colored wire of the pair. Terminate each conductor and the shield wire in each home run cable using the blue pluggable terminal block connector (Figure 5). Once the terminal block connectors are complete, plug them into the appropriate header on the SAS-JB circuit board as shown in Figure 5.
PAGE 8
Connect power (8 to 24 VDC) to the SAS-1 by means of a 2 position header on the SAS-CT. Use 18 or 20 gauge stranded cable (red and black color coded) terminated on one end using a pluggable terminal block connector and connected on the other end to the DC power source in the cabinet. Plug the connector onto the header on the SAS-CT as shown in Figure 6 for SASCT Rev 1 or Figure 7 for SAS-CT Rev 2.
