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
ABORT SWITCH.
• An abort switch shall not be used with a preaction system.
Appendix Figure B-2 UL-listed Abort Station
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:
• A monitor module wired to an abort station and programmed with the Type Code
ABORT
SWITCH
• All initiating devices and outputs with a common releasing zone in their zone maps -
ZR05 in the example shown
• A fully programmed releasing zone - releasing zone ZR05 in the example shown. (Refer
to "Releasing Zone" on page 46 for programming information.)
In the following example, when an initiating device activates (one of the two detectors or the pull
station), pressing and holding the abort switch while the delay time is in effect will prevent the
control panel from sending the command to dump releasing agents when the delay time expires.
