How to Program a Releasing Zone Releasing Applications
A.1.2 NFPA Releasing Applications
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:
A.2 How to Program a Releasing Zone
This section provides details for programming the releasing functions: Delay Timer, Abort Switch,
Cross Zone, and Soak Timer.
A.2.1 Programming a Delay Timer
Use a Delay Timer to specify the elapsed time between alarm activation of an initiating device and
activation of all output devices programmed as release circuits and mapped to that initiating device.
You can set the Delay Timer from 01 to 60 seconds, or to 00 for no delay. The figure below shows
graphical representation of a 15-second timer:
