5.2.1 Detector Loop Lengths
– Apollo, Hochiki and AV 16
With the above cables, loops can be up to 2Km in length. However, care must be taken when designing the
system to take into account the maximum loop loading. The voltage drop (load current x cable resistance) over
the cable always needs to be taken into account to ensure the devices receive an adequate supply voltage. The
following table gives recommendations for a loop. (It may be possible to extend the lengths where the devices
are distributed evenly
– refer to the device data sheets and Loop Calculators for further information on
calculating loop loading, cable cross sectional area and loop distance).
