3.3.2.7 Sensitivity
8
This parameter
shows if the device sensitivity is set to its “DEFAULT” or “CUSTOM” settings. For example:
[Loop 1 Devices] <More>
Address Sensitivity
001.0 DEFAULT
002.0 DEFAULT
002.1 --
003.0 CUSTOM
Press the
✔
button to change the sensitivity assigned to an input device. When selected, a new screen displays
the sensitivity settings assigned. For example:
SENSITIVITY ADJUST MODE (HEAT )
[ Alarm = 192 ]
[ Pre-Alarm = 160 ]
[ Delay = 0s][ Min.Value = 0 ]
[SAM/SSM]
Press the

buttons to highlight the required menu option and then press the
✔
button to select it. Use
the number buttons to enter the required value. Alternatively, press the
‘Esc’
button to cancel the changes.
The alarm thresholds and delay times can be unique for every device if required.
Always ensure that the values chosen are suitable for the particular installation and that reliable
fire coverage is maintained at all times.
3.3.2.7.1 Delay
The value in this field defines the delay from detecting an alarm to entering the alarm condition. The delay time
can be changed in 1-second increments.
3.3.2.7.2 Alarm
The Alarm Level is the level of the analogue value returned by the detector at which the panel will enter a Fire
Alarm Condition.
The alarm level value is fixed at 192 and cannot be changed.
3.3.2.7.3 Pre-Alarm
The Pre-Alarm Level is the level of the analogue value returned by the detector at which the panel will enter a
pre-alarm condition.
3.3.2.7.4 Minimum Value
If the detector analogue output falls below the minimum value programmed, the panel will enter a fault warning
condition. This parameter is a fixed value (0).
3.3.2.7.5 Mode
9
Specific detectors can be set to operate with defined sensitivity levels. Modes for multi-sensors are preceded by
the letter M.
