It may be necessary to disable more than one zone depending on the location of other SIR components and the area being serviced, refer to SIR Component Views . Refer to the illustration below, to identify the specific zone or zones in which service will be performed. After identifying the zone or zones, proceed to the disabling and enabling procedures for that particular zone or zones.
