The following chart shows the maximum number of displays that can be installed per cable/wire length
indicated. The cable/wire length can be increased by simply putting fewer displays on EACH CABLE
connected to the Model 910 Keypad. For example, when using 18 AWG wire, you can install a maximum of
four Model 960 (6-digit) Visual-Pager® displays up to 700 feet from the keypad on a single cable. However,
if a greater distance is required, simply use 16 AWG wire from the keypad. You can now install four Model
960 (6-digit) displays up to 1,200 feet from the keypad. The TOTAL CABLE LENGTH (sum of length of all
cables in the system) should not exceed 10,000 feet.
