Press the
✔
button to change the sensitivity assigned to an input device. When selected a new screen displays
the sensitivity settings assigned. For example, with an Apollo Discovery
SENSITIVITY ADJUST MODE (ION SMOKE )
[ Alarm = 55 ]
[ Mode = 3 ][ Pre-Alarm= 45 ]
[ Delay = 5s][ Min.Value= 8 ]
[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 Mode- Apollo:
This is applicable to Discovery devices only.
The panel fully supports the sensitivity modes within the Discovery devices. Refer to the Apollo technical
documentation for a detailed description and recommended use of these bands.
Different sensitivity modes can be chosen for both day and night periods. This field can be set in the range 1
–
5.
3.3.2.7.2 Mode- Hochiki:
This is applicable to Multi-sensor devices only:
Mode 0: (Default) Combined optical & heat detectors
Mode 1: Optical mode only
Mode 2: Heat mode only
3.3.2.7.3 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.
3.3.2.7.4 Alarm- Apollo
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 default value is 55. Setting the value higher will mean that more smoke / higher
temperature is required before the panel will enter the alarm condition. Setting the value lower will mean that
less smoke / temperature is required before the panel will enter the fire alarm condition.
The alarm level cannot be set outside the safe operating limits defined for the particular device.
Apollo Discovery devices always use a value of 55.
3.3.2.7.5 Alarm- Hochiki
The Alarm Level of the Analogue value returned by the detector at which the panel will enter a fire condition is
set to Hochiki Alarm thresholds (expressed as a % value) This is normally 3% for Multi-sensor & Optical
devices. Refer to Hochiki Data Sheets for further information.
3.3.2.7.6 Pre-Alarm
