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.
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
•
F2 button functions as the two stage advance to stage two button
•
F3 button functions as the automatic alarm signal cancel button
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 000 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 000 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 F3 switch has been pressed, the Alarm LED will turn from flashing to steady. 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 an F2 button in pressed, the NACs will progress to the second stage.
6.
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.
7.
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 that are already in 2nd stage activation will not
be affected.
8.
Any control modules assigned to special Zone 049 will be activated either by direct mapping of an input device programmed to
Zone 049 or if the timer counts down to zero or when any NAC goes into 2nd stage coding.
9.
Control modules that are programmed to the same zone as the activated input device will not be delayed for activation.
Zone
A maximum of five zones can be programmed to each main circuit board NAC. Pressing
1
while viewing
NAC Screen #3 displays the following screen:
Note that Z*** represents the Zone Number(s) corresponding to the selected NAC. The factory default for an unprogrammed device is
Z000 for general alarm zone. A flashing cursor will appear on the first
0
to the left. Enter the three digit number corresponding to the
zone that is to be assigned to this NAC. The cursor moves to the next Z*** designation. Continue entering zone assignments or the
remaining zones can be left blank or programmed as general alarm zone Z000. When all desired changes have been made, press the
Enter key to store the zone assignments. The display will return to the NAC Screen #3 which will show the zone assignments just
entered.
Silence Inhibit
The Silence Inhibit feature, when enabled, prevents the silencing of the selected main circuit board NAC for
a period of five minutes. Resetting the FACP will also be prevented for one minute while the NAC pro-
grammed for silence inhibit is activated. Pressing
2
while viewing NAC Screen #3 will cause the display to
change from the factory default of
Silence Inhibit No
to
Silence Inhibit Yes
. Each press of the
2
key will
cause the display to toggle between the two options.
Sync Type
If synchronized strobes were selected as the Type of device installed, the type of synchronization must be
selected in this option. Pressing
1
while viewing NAC Screen #4 will cause the following screen to be dis-
played:
