4.7 Releasing Applications
4.7.1 Overview
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:
4.7.2 Programming
The control panel supports up to ten releasing software zones. You can map these zones to activate
Control Panel releasing outputs and FCM-1 modules. Program the FCM-1 module for the
appropriate type code according to the chart below:
For more information, refer to the NFS-320/E/C
Programming Manual.
