should be routed back to the HALO RS-485 Network. It is highly recommended that you employ an RS-
485 Repeater, available from EXI, in the Elevator Control Room to separate the Elevator connections from
the main HALO network. The Repeater isolates the noise that may be picked up during elevator operation,
boosts the RS485 signal, and reduces the total capacitance on the network to ensure reliable operation.
5.10.2. LOCATION FOR SRA-E EXCITER ANTENNAS
One of the most important aspects of the entire installation is the correct positioning of the SRA-E
Antennae. The two antennae are to be mounted under each side rail in the center position of the elevator
sidewall, opposite each other. This is the recommended location and you may improvise depending on the
design of the elevator car.
• Place the SRA-E template, or an antenna, on the center of the elevator wall, at least 1” below the
handrail. Use the screw holes on the template to mark the location of the mounting screws and hole for
coax cable entry, and drill holes as required.
• Remove the cover from the SRA-E, thread screw anchors (not provided) into the elevator wall to the
correct depth, insert the screws into the SRA-E nylon foot, then thread the screws into the anchor
receptors so the SRA-E mounts securely to the elevator wall.
• Repeat this procedure for the opposite side.
• Once the Antennae are mounted, run the Antenna Coaxial cables down from the Controller Cabinet on
each side of the car. Draw the cables through the ½” holes on the nylon foot on each side and connect
the mating coax fitting on each of the SRA-E antenna. Then replace the cover on each antenna.
