Appendix A: Releasing Applications

WARNING: When used for CO
NFPA 12. Do not enter the protected space unless physical lockout and other safety procedures
are fully completed.
Do not use software disable functions in the panel as lockout.
Do not enable the BACKUP option switch for any of the four Notification Appliance Circuits
(NACs) if they are used for releasing functions.
The control panel includes ten Releasing Zones (R0-R9) that can be used to control up to ten releasing
operations. Each zone operates independently, and is fully programmable.
Note: Releasing Zones R0-R9 appear in the CBE list of devices as ZR0-ZR9. For example, if you list R5 for a
detector, one of the five zones in the CBE list of the detector will display as ZR05.
From the "Special Function Change" screen (refer to "How to Program Special Zones (6=SPL
FUNCT)" on page 29), select a Releasing Zone (R0-R9) to display the "Releasing Function" screen:
PRG RELEASE FUNCTION RELEASE CONTROL
DELAY=30 ABORT=ULI CROSS=N SOK=0000 R05
Each Releasing Zone includes four releasing functions, outlined below:
Function Lets You
Delay Program a 0160-second Delay Timer (or 00, no delay). The Delay Timer equals the
time that must elapse between activating an initiating device and activating the
releasing zones mapped to the active initiating device. Refer to "How to Program a
Delay Timer" on page 54.
Abort Select a 3-letter Abort switch Type Code (ULI, IRI, NYC, or AHJ) that adds a delay
time to a Releasing Zone, or prevents a release of a Releasing Zone. Refer to "How to
Program an Abort Switch" on page 54.
Cross Select one of three Cross Zone types or "N" (not used). A Cross Zone requires tripping
two or more devices to activate the outputs mapped to one of the Releasing Zones.
Refer to "Using Cross Zones" on page 62.
Soak Select a Soak Timer (0001-9999 seconds) or "0000" (not used). Refer to "How to
Program a Soak Timer (NFPA 16 Applications Only)" on page 64.
This control panel can be used for agent release or preaction/deluge control applications. In a properly
configured system with compatible, listed actuating and initiating devices, this control panel complies
with the following NFPA standards for installation in accordance with the acceptable standard:
