1.
Press 'No' to reject the value shown and then enter the required numeric value. For example, enter a
level of 62.
2.
The display will then prompt the pre-alarm threshold level.
---------------------------------------------
1.
Press 'No' to reject the value shown and then enter the required numeric value. For example, enter a
level of 50.
The panel will not allow the pre-alarm threshold to be higher than the fire alarm.
If the value shown is correct, press Yes to step on and leave the value unchanged.
The values presented and entered depend on the make of signalling device. Refer to the
instructions supplied with the loop driver card for information on allowed settings.
•
Both thresholds have now been set and the display reverts to showing the present analogue output
from the sensor. However, because alternative pre-alarm and fire alarms have been set the display
will automatically show these whenever this device is called up in the inspect or configure modes.

Ion Smoke
•
P=050 signifies the daytime pre-alarm is now at 50. F=062 signifies the daytime fire alarm is now at 62.
•
Step through and adjust any other devices as required.
•
These alternative thresholds are enabled as defined in the Day Mode setup configuration.
The panel will not allow the threshold to be raised above the measuring range for the
sensor, however the commissioning engineer should always test the detector and prove
that the system is giving proper fire protection.
Apollo 'Discovery' detectors also support programmable sensitivity bands, defaulting to
'band 3'. When the panel detects a Discovery device, it will precede the fire threshold level
shown above with an option to also change the sensitivity band during day mode operation.
If required, change the sensitivity bias towards band 1 (smoke) or band 5 (heat).

Restoring Sensitivity Defaults
•
Each time the panel performs an 'Auto Learn', it will check to see if a different type of detector has
been installed to the device type information stored in memory. If so, the panel will automatically reset
the pre-alarm and fire alarm settings back to the standard factory defaults.
