Appendix B: Releasing Applications
B.1 Releasing Zones
The control panel includes ten releasing zones (ZR00-ZR09) that can be used to control up to ten
releasing operations. Each zone operates independently, and is fully programmable. To program a
releasing zone, refer to Section 3.4.4, “Releasing Zone”, on page 57.
There are four releasing functions, ou
tlined below, that can be defined by entering values in the
associated fields during programming.
WARNING:
DO NOT RELY ON DISABLE TO DISABLE RELEASING POINTS DURING TESTING.
RELEASING POINTS MUST BE PHYSICALLY DISCONNECTED.
Function/Field Explanation
Delay Time Delay Time is the time that elapses between activation of a
n initiating device and activation
of all outputs mapped to the initiating device through a releasing zone.
Delay Time can have a value of 0 to 60 (seconds). A value of 0
will result in immediate
output activation upon activation of the initiating device.
Following is a graphic representation of what ha
ppens when a delay time
r is set to 15
seconds for releasing zone ZR02.
NOTE: If cross-zoning is in effect, the delay time will not begin until the cross-
z
o
ning conditions are met. Refer to Appendix B.3.5, “Cross Zones”, on page 104 for
more information.
Abort Switch Selection of a 3-letter abort switch type code (ULI, IRI, NYC, or AHJ) defines the operation
of
an Abort Switch in
that releasing zone. Refer to the specific abort switch type code
heading in this appendix for details on how each functions.
Cross Zone Select one of three Cross Zone types (Yes, Zone, or Heat), or No (not used). A Cross Zone
r
equires tripping two or
more initiating devices to activate the outputs mapped to a
releasing zone. Refer to the Section B.3.5 on page 104 section of this appendix for details
and examples.
Soak Time (NFPA

pplications
only)
Soak Time specifies the length of time to dump releasing agents when a releasing zone
activates. When the Soak Time expires, the control panel automatically shuts the releasing
solenoids for the active releasing zone. Soak Time can have a value of 0 to 9999 seconds.
If Soak Time is set to 0, the releasing solenoids will remain active until system reset.
Following is a graphic representation of what ha
ppens when soak time is set
to 300
seconds for releasing zone ZR02.
