How to Program a Releasing Zone Releasing Applications
Figure A.9 Illustrated Example of Cross Zone Programming
A listing of each Cross Zone option and the conditions required to activate the Releasing Zone,
according to the example shown above.
Select a time for the Releasing Zone Delay Timer (refer to“Programming a Delay Timer” on page
61.)
Cross Zone
Selection (Cross=)
Condition(s) Required to Activate the Releasing zone
Cross=N An alarm from any detector or module 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
• An alarm from 2D102 and 2D104
• An alarm from 2D101 and 2D104
• An alarm from 2D102 and 2D103
The two detectors listed in each set above are each mapped to different
zones, but both list ZR1 in their CBE.
Cross=H Activation of heat detector 2D104 and one smoke detector (2D101,
21D102, or 2D103) or a module mapped to the same releasing zone.
To Program Do this
Cross Zones Type N, Y, Z, or H in the CROSS= field, or press the
NEXT or PREVIOUS keys,
or , until N, Y, Z or H appears in the that field.
