selections are:
Y Two or more detectors are alarmed that are mapped to one of the ten
Releasing Zones (R0-R9)
Z Two or more detectors are alarmed that are mapped to two different
Software Zones and mapped to one of the ten Releasing Zones (R0-R9).
H At least one smoke detector mapped to one of the ten Releasing Zones
(R0-R9) is alarmed and at least one heat detector mapped to the same
Releasing Zone as the smoke detector is alarmed.
N Cross Zones not used
Delay Timer Select a 0–60 second delay before activating a zone.
Abort An Abort Switch Type Code used to abort activation of a zone.
