NOTE: When setting up multiple zones in one
area (such as a motor room), stagger these
zones as they enter the RLDS. For example, if
there are two motor rooms served by one
RLDS, each motor room has three sensing zones. Make
the first motor room zones 1, 3, and 5, and make the
second motor room zones 2, 4, and 6. This will allow the
leak detection system to return to that area being sensed
more regularly.
If the zone exists in a location where air flow will
affect the dispersion of refrigerant, reduce the alarm
limits to a lower level than usual. This will allow for
dispersion of the refrigerant in the air.
