NFPA Releasing Applications
B.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:
B.3 Abort Switches
The control panel provides for four types of abort switches - ULI, IRI, NYC, and AHJ - each of
which will affect the operation of the delay timer in the releasing zone. For example, an NYC Abort
Switch for releasing zone ZR05 affects only the delay timer in ZR05.
When an initiating device activates, pressing and holding the abort switch will prevent the control
panel from sending the command to dump releasing agents when the Delay Time expires.
Requirements for using an abort switch include the following:
• A monitor module must be connected to a UL-listed abort station, such as the NBG-12LRA
shown below.
• The monitor module must be programmed with the Type Code
• An abort switch shall not be used with a preaction system.
This section contains information on each type of abort switch.
Example of an Abort Switch Application
The figure below contains an illustration for an abort switch application configuration using
releasing zone ZR05 as an example. The configuration includes:
