4. DEPLOYMENT GUIDELINES
1. All loops are nonloaded only.
2. For loops with 26-AWG cable, the maximum
loop length including bridged tap lengths is 9 kft.
3. For loops with 24-AWG cable, the maximum
loop length including bridged tap lengths is
12 kft.
4. Any single bridged tap is limited to 2 kft.
5. Total bridged tap length is limited to 2.5 kft.
6. The total length of multigauge cable containing
26-AWG cable must not exceed the following:
12 - {(3*L
)/(9 - L
26
L
= total length of 26-AWG cable
26
excluding bridged taps (in kft.)
L
= total length of all bridged taps (in kft.)

7. Recommended loop resistance for circuit
deployment is ≤ 750 Ω (9 kft. of 26 AWG).
