D. LOOP RESISTANCE TESTS 
4.08 Keysets must not exceed the loop limit of 800 feet or 40 
ohms, using 24 AWG wire. The loop limit applies to any station, 
even with a Power Failure Transfer keyset. Door-Mate units must 
not exceed loop limits of 400 feet or 20 ohms. 
4.09 Excessive and/or high resistance connections reduce the 
cable lengths. Using larger gauge (smaller AWG number) or 
multiple 24 AWG wires for the...
