Programming a ULI Abort Switch
The following contains information needed to program a ULI Abort Switch:
Description A standard UL-type delay timer that complies with UL Standard 864.
How to program 1. Program the monitor module connected to the abort station with the Type Code
ABORT SWITCH as detailed in “How to Modify an Addressable Monitor Module
Point” on page 23.
2. Select a time for the Releasing Zone Delay Timer (refer to“How to Program a
Delay Timer” on page 54).
3. Press at this point to save the Abort Switch value if no other fields on the
screen are changing. To change another field on the screen, move the cursor into
position by pressing the arrow keys on the keypad.
How it works
When an alarm initiates in the programmed Releasing Zone, you can press and hold the Abort
Switch while the Delay Timer continues to count down. (If the delay timer has expired, the abort
switch has no effect.) When you release the Abort Switch, a 10-second ULI timer counts down.
At the end of the 10-second ULI timer, the control panel activates the Releasing Zone outputs.
Example
A ULI Abort Switch and a Delay Timer programmed to Releasing Zone R05:
