A.2.2 Abort Switches
Definition of Abort Switches
The control panel provides for four (4) types of Abort Switches (ULI, IRI, NYC, and AHJ) that you
can use, that will affect the operation of a Delay Timer mapped to the same Releasing Zone. For
example, an Abort Switch selected for Releasing Zone R05 only affects the Delay Timer selected
for R05. Other requirements for using an Abort Switch include the following:
• Connecting a monitor module to a UL-listed abort station, such as the NBG-12LRA shown
below.
• Program the monitor module with the Type Code
ABORT
SWITCH
Addressable Monitor Module Point” on page 22.)
• Abort switch shall not be used with a preaction system or a CO
2
system.
Figure A.2 UL-listed Abort Station
This section contains information for programming each type of Abort Switch for a Releasing
Zone.
How an Abort Switch Works
The figure below contains an example for configuring an Abort Switch and shows the requirements
for using an Abort Switch for Releasing Zone R05, which are:
• A monitor module is wired to an abort station
• The monitor module is programmed with the Type Code,
ABORT
SWITCH
• All initiating devices and outputs are mapped to a common Releasing Zone (R05 shown)
• Releasing Zone R05 is programmed with the releasing functions: Delay, Abort, Cross, and
Soak
