The programmer can select the notification appliance output by pressing the number
corresponding to the desired output. The coding selections are:
• Steady - a continuous output with no coding
• March Time - 120 ppm (pulse-per-minute) output
• California - 10 seconds on and 5 seconds off
• Temporal - ½ second on, ½ second off, ½ second on, ½ second off, ½ second on, 1½ second
off
• Two Stage 3 Minutes or 5 Minutes - Refer to "Two Stage Operation" on page 99. for a
description of this feature
Selection of one of the above options will cause the control panel to store the information in
memory and return the display to NAC Screen #2, which will display the new coding choice.
3.6.5.5.5.1 Two Stage Operation
Two Stage operation consists of the following:

If Two Stage operation is programmed as the Coding option, the following sequence of events
will occur during an alarm.
1. The on-board NACs which are programmed to General Alarm Zone 0 will activate with a
