The Axis
AX
fire alarm control panel has two (2) methods of handling a detector that reaches 100% calibration:
Method One:
Method one is the default method of handling 100% drift detectors. When a detector reaches 100% drift, it activates
a specific trouble signal “Device Dirty” for the detector address, at the Axis
AX
fire alarm control panel. This trouble
will remain active until the detector is cleaned/recalibrated or replaced. Acknowledgement of the trouble is possible
to silence the panel trouble buzzer, however it will resound within 24 hrs from the time the device reported the
trouble.
Method Two:
Method two is an enhanced method of handling 100% drift detectors, usually utilized when customers have a
service contract with the installation site. In this method, field configuration programming tool setup, detector
compensation is programmed to perform compensation based on time-of-day, day-of-week, etc. With the
programming of time-of-day, day-of-week, etc. compensation (detector dirty reports – if any) will occur at this
programmed time.
When a detector reaches 100% drift, it is placed in an Off-Normal, Problem area within the Axis
AX
fire alarm control
panel. The Problem area is viewable by a service technician on his next service/maintenance visit to the site. At this
time, detectors that are in the Problem area can be cleaned/recalibrated or replaced. In addition to placing 100%
calibrated detectors in the Problem area of the Axis
AX
fire alarm control panel, email reports can be transmitted via
the Advanced’ optional AX-LAN (ipGateway), so service personal can respond and rectify the dirty detector prior to
the customer being notified.
Note: With the enhanced method of programming compensation, when a “Problem” detector tries to
recalibrate and cannot maintain the programmed detector sensitivity, a trouble signal “Device Dirty” for the
specific detector will be generated at the Axis
AX
fire alarm control panel.
11.1.2 Rapid Compensation
As previously indicated, compensation for environmental conditions of an installation is a standard feature of all
Axis
AX
intelligent detectors. Approximately every 24 hours (default setting), intelligent detectors are evaluated and
compensated (if required) for any changes to the installed environment, due to device contamination and/or dust
buildup.
Rapid compensation is a feature built into the AX-CTL-1L, AX-CTL-2 and AX-CTL-4 intelligent fire alarm control
panel that allows the user to manually perform a drift compensate of SLC loop devices when they are first installed
or if they are cleaned/replaced. It is recommended that during commissioning, cleaning or when replacing a
detector rapid compensation be performed on detectors, to adjust them immediately to the present ambient
conditions.
Note: If rapid compensation is not employed on a replaced device it could take up to 24 hrs before the
replaced device is automatically compensated.
Highlight the required Axis
AX
intelligent detector, select RAPID COMPENSATION and then press the
✔
button to
confirm. The panel will now instruct the intelligent detector selected to perform a rapid compensation. This will take
approximately 30 seconds.
This operation must only be performed with the detector in clean air.
No other operation should be performed on this device during this rapid compensation period.
11.1.3 View EEPROM
The panel can read any of the extended memory locations within the intelligent detectors.
Highlight any “Axis
AX
intelligent detector, select VIEW EEPROM and then press the
✔
button to confirm. The
display will prompt for entry of the required extended memory address. For example:
