•
These alternate 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.
5.2.3.5 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 restore the pre-alarm and fire alarm settings back to the standard defaults.
•
All detector settings will be returned to default if an "Auto Learn" is performed with the sensors disconnected.
5.2.3.6 Device Actions
•
The action taken by both smoke and temperature detectors is fixed to always give pre-alarms and fires.
•
Most other devices can have their alarm action re-defined as required.
•
This ability to change the alarm action is signified on the display by the option “Action” appearing on the device
menu when the change key is pressed. Press
6
to select the action option and the display will show the current
action assigned to the input device. For example a call-point (pull station) will normally show :-
Action > Zone Fire ?
•
If the action shown is not correct for the application, press the “
Change
” key. Each time the “
Change
” key is
pressed the action will cycle through the available options. The available actions are :-
