5.7 Appendix 7 – Mx4000 Series Loop Output Drive Capability
The following information is applicable per loop. All loops can be loaded to the maximum (500mA per loop).
Provision has been made to allow for a typical loading of detectors and inputs (30mA).

The number of devices shown is representative for specific loop arrangements. If there is a
mixture of sounder types or sounder volumes on the installation or if the other devices on the
loop take more than 30mA in quiescent or alarm, then calculate the actual current load in
alarm using the current consumption figures quoted in the device data sheets and ensure that
this does not exceed the maximum output for the loop.
Refer to Section 5.2.1 and to Apollo and Hochiki Loop Calculators for further information on
calculating loop loading, cable cross sectional area and loop distance.
