Auxiliary Power
The nonessential functions of an attendant console and its optional 26A1 or 24A1 selector console derive power from an auxiliary power source. Provide auxiliary power for an attendant console through this cable so the console remains fully operational during short power outages.
NOTE:
Only 1 console can derive auxiliary power from the system and through the auxiliary cable located in the trunk/auxiliary field.
A console’s maximum distance from its auxiliary power source is:
■800 feet (244 m) for a 302A1
■350 feet (107 m) for a 301B1 and 302C1
An attendant console can also derive auxiliary power from:
■Individual 1151A or 1151A2 power supply
■
■
■Bulk power supplies such as the 1145A1
