3.4.3 Set Sector Day/Night Alarms
1 Press MAIN MENU to enter the Main Menu list from Normal display mode
2 Use Parameter UP & DOWN buttons to reach SECTORS ALMS
3 Press ENTER
4 Enter Level 1 code or above
The display will now show DAY VALUES, use Parameter UP & DOWN to change to NIGHT VALUES.
Press ENTER to access the settings for all the sectors.
This function allows the user to set different values for day and night operation. The time of day when the values switch is also
configurable. Values can be set for ‘ALL’ sectors or each sector individually. The FT1 only has ‘ALL’ settings due to it having no sectors.
Parameter Range - /m Factory Default
ALL F2 All Fire 2 Alarm Levels 0.01 - 20% 1%
ALL F1 All Fire 1 Alarm Levels 0.01 - 20% 0.08%
ALL ACTION All Action Alarm Levels 0.01 - 20% 0.06%
ALL ALERT All Alert Alarm Levels 0.01 - 20% 0.04%
TRACE Trace Level 0.01 - 20% 0.03%
F2DEL Fire 2 Delay (seconds) 0 - 60s 3s
F1DEL Fire 1 Delay (seconds) 0 - 60s 3s
ACTDEL Action Delay (seconds) 0 - 60s 3s
ALTDEL Alert Delay (seconds) 0 - 60s 3s
TRCDEL Trace Delay (seconds) 0 - 60s 3s
In order to comply with UL approval requirements based on open area applications at maximum dilution, when using
Obscuration/foot, the FIRE 1 threshold must be set within the limits specified below:
FIRE1
FT 1,4,6 0.04-0.16 %/ft
FT 8,15 0.04-0.7 %/ft
PICO 0.04-0.29 %/ft
By default, NIGHT VALUES are set to the same as DAY VALUES. DELAYS are automatically the same for both DAY and
NIGHT.
ALL ALERT, ALL ACTION, ALL F1, ALL F2
Progressive Obscuration levels corresponding to these alarm events. Default values are 0.04%, 0.06%, 0.08% and 1%. Changes
made should preserve their progressive relationship. The values apply equally to OVERALL sampling and to TRACE sampling. The
range is 0.01 to 20% Obs/m (0.01 – 6.09% Obs/ft)
TRACE
The obscuration level (in OVERALL sampling) which will cause the FireTracer to begin Sector scanning. The default value is
0.03%. The range is 0.01 to 20%.
TRCDEL, ALTDEL, ACTDEL, F1DEL, F2DEL
The time period for which the corresponding obscuration Levels must be sustained before triggering an alarm. Prevents spurious
Alarm events. Default values are all 3 seconds. The range is 0 to 60s. To set the values for each sector individually choose the
required sector (e.g. S1…..S15 on a FT15) and the same F2, F1, ACTION and ALERT options are available.
