Condition(s) Required to Activate the Releasing zone
Cross=
N
An alarm from any detector activates the releasing circuit.
Cross=
Y
An alarm from any two detectors or modules activates the releasing
circuit.
Cross=
Z
An alarm from two detectors or modules mapped to different Software
Zones, but mapped to the same Releasing Zone.
• An alarm from 2D101 and 2D103 – detectors mapped to different
zones, but both list ZR1 in their CBE.
• An alarm from 2D102 and 2D104 – detectors mapped to different
zones, but both list ZR1 in their CBE.
• An alarm from 2D101 and 2D104 – detectors mapped to different
zones, but both list ZR1 in their CBE.
• An alarm from 2D102 and 2D103 – detectors mapped to different
zones, but both list ZR1 in their CBE.
Cross=
H
Activation of heat detector 2D104 and one smoke detector (2D101,
2D102, or 2D103).
