1Introduction
This Service Manual explains how to service and calibrate the Ax60+. It is intended for system installers and service
engineers. For information on installation and operation, refer to the Ax60+ User Manual P0159-800, downloadable from
Analox.
1.1 Warnings, Cautions and Notes
WARNINGS ARE USED IN THIS MANUAL TO INDICATE POTENTIALLY HAZARDOUS SITUATIONS
WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.
CAUTIONS ARE USED IN THIS MANUAL TO INDICATE POTENTIALLY HAZARDOUS SITUATIONS
WHICH COULD RESULT IN EQUIPMENT DAMAGE OR LOSS OF DATA.
NOTES ARE USED IN THIS MANUAL TO INDICATE SUPPLEMENTARY INFORMATION THAT IS NOT
HAZARD RELATED.
1.2 Safety information
WARNING: READ THE SAFETY INFORMATION IN THIS MANUAL BEFORE SERVICING THE AX60+.
WARNING: DO NOT TEST THE ALARM WHEN IT IS CLOSE TO THE EARS. IT HAS A HIGH VOLUME
SOUNDER WITH A SOUND LEVEL OF 88 DECIBELS AT A DISTANCE OF 3 METRES.
WARNING: DO NOT TEST THE ALARM WHEN IT IS CLOSE TO THE EYES. IT HAS A HIGH VISIBILITY
STROBE LIGHT WITH A LUMINOUS INTENSITY OF 100 CANDELA.
WARNING: DO NOT OPEN THE CENTRAL DISPLAY, SENSORS OR ALARMS IF THEY ARE CONNECTED
TO THE POWER SUPPLY. FIRST DISCONNECT AND ISOLATE THEM FROM LIVE HAZARDOUS
VOLTAGE.
1.3 Other information
NOTE: THE DATA OUTPUT MODULE DOES NOT REQUIRE ANY ON-SITE SERVICING, HOWEVER,
THE DATA OUTPUT MODULE DOES CHECK FOR A NUMBER OF FAULT CONDITIONS, SEE SECTION

2Configuring sensors
2.1 Hardware setting
In a standard Ax60+ system (not including the Kiosk option) each sensor must have its jumper link set to a different
location e.g. Sensor 1=location 1; Sensor 2=location 2.
The Sensor has a hardware setting that is factory configured for a system with only one Sensor. If a system includes two,
three, or four Sensors then the hardware must be reconfigured by moving a jumper link ( ) in each Sensor installed
in the system.
WARNING: DISCONNECT AND ISOLATE THE AX60+ SYSTEM FROM THE MAINS POWER SUPPLY
BEFORE OPENING THE CO2SENSOR ENCLOSURES.
To access the jumper link, open the Sensor enclosure. The printed circuit board (PCB) has a SENSOR LOCATION selector
with one link, factory installed in LOCATION 1.
The image to the right shows the jumper link in position
1 (Factory default).
For a system with only one Sensor, the jumper link
should be retained in LOCATION 1.
For a system with two Sensors, the first Sensor’s
jumper link should be in LOCATION 1 and the second
Sensor’s link in LOCATION 2.
For a system with three Sensors, the first Sensor’s link
should be in LOCATION 1, the second Sensor’s link in
LOCATION 2 and the third Sensor’s link should be in
LOCATIONLOCATION 3.
For a system with four Sensors, the first Sensor’s
jumper link should be in LOCATION 1, the second
Sensor’s link in LOCATION 2, the third Sensor’s link in
LOCATION 3 and the fourth Sensor’s link should be in
LOCATION 4.

5Calibrating Ax60+ sensors
5.1 CO2sensor calibration proof test
The Ax60+ CO2Sensors can be checked to ensure that they accurately measure carbon dioxide and displays the correct
reading. Analox can supply the following check kit:
Ax60+ CO2Check Kit comprising:
Part number
Description
Gas type
Contact Analox or source
locally
110-litre pure air (20.9% oxygen, balance nitrogen)
CO2 Low Check
Contact Analox or source
locally
110-litre 3.0% carbon dioxide, balance nitrogen
CO2 High Check
Contact Analox or source
locally
0.5-litre/minute regulator to fit 110-litre bottle
1817-5000
2-metre neoprene tubing
8000-0910A
Push-in flow adaptor
Checking CO2Sensors is an easy task that does not require software input. This procedure is suitable for the standard
Ax60+ option only. Follow the procedure below:
NOTE: IF THE OPTIONAL SENSOR SPLASHGUARD IS FITTED, REMOVE IT BEFORE CHECKING
AND/OR CALIBRATING THE SENSORS.
1] Ensure the Ax60+ is powered on and operating normally.
2] Fit the neoprene tubing (1817-5000) to the flow adaptor (8000-910A).
3] Fit the flow adaptor into the aperture on the CO2 Sensor (see below, left).
Step [3] Fit the flow adaptor into
the aperture on the CO2Sensor
Step [4] Fit the regulator to the CO2low
check gas bottle

4] Fit the regulator to the CO2 low check gas bottle (see above, right).
5] Carefully open the regulator valve and allow the CO2 low check gas to flow across the sensor.
Do not block the exit of the flow adaptor.
6] Ensure that the Ax60+ display reading is between 400ppm and 550ppm
7] Close the regulator valve, acknowledge the alarm and ventilate the area.
8] Repeat the procedure using the CO2 high check gas bottle to check the display reading shows
between 30000 –30150ppm CO2
5.2 CO2sensor calibration adjustment
The Ax60+ CO2Sensor(s) can be recalibrated to ensure they accurately measure carbon dioxide at the specified levels.
Analox can supply the following calibration kit:
Ax60+ CO2Calibration Kit comprising:
Part number
Description
Gas type
Contact Analox or source
locally
110-litre pure air (20.9% oxygen, balance nitrogen)
CO2 Zero
Contact Analox or source
locally
110-litre 3% carbon dioxide, balance nitrogen
CO2 Span
Contact Analox or source
locally
0.5-litre/minute regulator to fit 110-litre bottle
1817-5000
2-metre neoprene tubing
8000-0910A
Push-in flow adaptor
Recalibrating CO2Sensors is a similar task to checking but it also requires software input.
Calibration adjustment is a two-point process: a ‘zero calibration adjustment’ and a ‘span calibration adjustment’.
NOTE: ZERO CALIBRATION ADJUSTMENT MUST BE PERFORMED BEFORE SPAN CALIBRATION
ADJUSTMENT.
5.2.1 CO2sensor zero calibration (Displayed as Zero cal.)
NOTE: THE SENSOR THAT IS BEING CALIBRATED IS AUTOMATICALLY DISABLED DURING
CALIBRATION. THE OTHER SENSORS CONTINUE TO OPERATE.
NOTE: CALIBRATION MODE AUTOMATICALLY TIMES OUT AFTER TEN MINUTES.
To zero calibrate a CO2Sensor, follow the procedure below (in both text and menu map):
1] Ensure the Ax60+ is powered on and operating normally.
2] Press and hold Cancel+Cycle for 6 seconds to display Top-level Menu.
3] Press Cycle four times to display Calibration. Press Accept/Test to display Zero cal.
4] Press Accept/Test to show the Select sensor screen, press Cycle to select the Sensor you want
to calibrate.
5] Press Accept/Test to select the Sensor. The Zero level (#) screen displays.
6] Fit the neoprene tubing (1817-5000) to the flow adaptor (8000-
0910A).
