108 MS-9200UDLS PN 52750:E1 01/27/09
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 - refer to "Two Stage Operation" on page 108 for a description
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:
• 1st stage output - 20 ppm (pulse-per-minute) coding
• 2nd stage output - Temporal coding as described above
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 1st stage output upon activation of any alarm point
2. If the activated alarm point is directly mapped to a zone which is programmed
to an on-board NAC, that NAC will go directly to 2nd stage coding output.
All other NACs not directly mapped to the activated alarm point’s zone but
assigned to Zone 0 will activate with a 1st stage output
3. If, after the programmed time of 3 or 5 minutes, the Acknowledge switch has
not
been pressed, all NACs presently in 1st stage activation will go to 2nd
stage activation
4. If an Acknowledge switch has been pressed, any NACs currently in 1st stage
activation will remain in 1st stage. Pressing the Acknowledge switch does
not affect NACs already in 2nd stage activation
5. If another alarm point is activated and the countdown timer is counting, the
alarm point will have no effect on the NACs unless the alarm point’s zones
are directly mapped to one of the NACs, in which case it will follow the
procedure outlined in step 2
6. If another alarm point is activated and the countdown timer has stopped
counting due to the Acknowledge switch being pressed, the countdown timer
will restart and the NACs will respond as outlined in step 2. NACs already in
2nd stage activation will not be affected
7. Any control modules assigned to special Zone 99 will be activated either by
direct mapping of an input device programmed to Zone 99 or if the timer
counts down to zero or when any NAC goes into 2nd stage coding
8. Control modules that are programmed to the same zone as the activated input
device will not be delayed for activation
