60 NFS2-640/E Programming Manual — P/N 52742:L2 7/17/14
Appendix A: Releasing Applications
A.1 Overview
A.1.1 Description of Releasing Zones
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..
From the “Special Function Change” screen (refer to “Program Special Zones (6=spl funct)” on
page 27), select a Releasing Zone (R0-R9) to display the “Releasing Function” screen:
Each Releasing Zone includes four releasing functions, outlined below:
WARNING:
When used for CO
2
releasing applications, observe proper precautions as stated in 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.
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.
Table A.1 Releasing Zone Functions
Function Lets You
Delay Program a 01 to 60-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 “Programming a Delay Timer” on
page 61.
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 “Abort Switches” on
page 62.
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 70.
Soak Select a Soak Timer (0001-9999 seconds) or “0000” (not used). Refer to “Programming a
Soak Timer” on page 72.
