Safety information
Warnings are used in this Quick Start Guide to indicate potentially hazardous situations which
could result in serious injury or death. Cautions are used to indicate potentially hazardous
situations that could result in equipment damage or loss of data. Notes are used to provide
information that is important but not hazard related.
WARNING:
READ THE SAFETY INFORMATION IN THIS QUICK START GUIDE
BEFORE INSTALLING OR USING 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:
ENSURE YOU PERFORM A RISK ASSESSMENT BEFORE INSTALLING
CO2 SENSORS AND CO2 ALARMS. IDENTIFY POTENTIAL SOURCES
OF CO2 LEAKS AND AREAS OF HUMAN OCCUPATION. DO NOT USE
A SINGLE CO2 SENSOR TO COVER MORE THAN 80M3. USE
ADDITIONAL CO2 SENSORS IF AN AREA HAS A COMPLEX SHAPE,
PHYSICAL OBSTACLES, POOR VENTILATION OR ZONES WHERE
CO2 MAY COLLECT.
WARNING:
INSTALL CO2 SENSORS AT A HEIGHT OF 12–18" (305–457MM)
ABOVE FLOOR LEVEL. THIS IS BECAUSE CO2 IS HEAVIER THAN
AIR AND MAY COLLECT AT A LOW LEVEL.
WARNING:
INSTALL O2 SENSORS AT AVERAGE WORKING HEAD HEIGHT
WARNING:
DO NOT OPEN THE CENTRAL DISPLAY, SENSOR OR ALARM IF THEY
ARE CONNECTED TO THE POWER SUPPLY. FIRST DISCONNECT
AND ISOLATE THEM FROM LIVE HAZARDOUS VOLTAGE.

Ax60+ Multi-Gas, Hard Wired Option
Quick Start Guide

Int. Approved
Introduction
This Quick Start Guide explains how to install and use the Ax60+ Hard Wired option. For more
information on operation and maintenance, refer to the Ax60+ User Manual P0159-800. For more
information on servicing and calibration, refer to the Ax60+ Service Manual P0159-803. These
are available to download from http://www.analox.net/
The standard Ax60+ is available as either a Hard Wired or a Quick Connect option. This choice
must be made when placing the order. Hard Wired systems are intended to be integrated with
the building fabric. Quick Connect systems are pre-wired with Cat5e cables fitted with colourcoded RJ45 connectors for easy installation. Both require the installer to connect the power
supply unit and optional beacon to the Central Display.
The Ax60+ Kiosk option is a more compact solution that offers the convenience of Quick Connect
cabling and does not require a Central Display unit.
1.1
Purpose of the Ax60+
The Ax60+ is a life-safety device to be used for atmosphere monitoring. If a Sensor detects a
potentially dangerous gas level it triggers an appropriate alarm on the Central Display which is
then announced by the Alarms.
The Central Display provides real-time gas readings from each Sensor together with any alarm or
fault indications. The Central Display can be easily interrogated to show detailed information on
the Sensors and Alarms that are connected to it.
An Ax60+ Central Display can be connected to a maximum of four Sensors and a maximum of
eight Alarms. To extend the alarm functions, an optional beacon is available and two alarm-relay
outputs are provided for integration with other systems.
The Central Display is usually installed in a principal location (e.g. a Manager‘s office) and
connected to one or more Sensors fitted in remote areas such as store rooms or service
corridors.
The Sensors send alarm signals to one or more Alarm units in locations where they can be
observed by management or crew. The Central Display monitors the Sensors and displays their
current status and measurements.
1.2
Operation at altitude
The toxic effects of CO2 are dependent on the partial pressure, or the quantity of gas molecules,
not the percentage in the atmosphere; therefore at altitudes above 900 metres (3000 feet)
alarms will operate below the factory calibration point. Please refer to our website
www.analox.net for details of suitable alarm setpoints and calibration procedures at altitude. Note
that this must be performed by an authorised engineer.
NOTE:
THE SYSTEM IS SAFE AT ALTITUDE WITH FACTORY CALIBRATION,
HOWEVER IF CONFORMITY MUST BE SHOWN TO A REGULATION
QUOTING PERCENTAGE IN THE ATMOSPHERE THIS CAN BE ACHIEVED
BY PERFORMING A LOCAL CALIBRATION.

Installation
CAUTION: SOME ENCLOSURES ARE SUPPLIED UNFASTENED WITH FIXING SCREWS
LOOSE. DO NOT OVER-TIGHTEN THE SCREWS WHEN FASTENING THE LIDS ON.
2.1.1
Central Display
Retain the clear protective film on the fascia until
the installation is complete. Using the supplied
paper template mark out the wall-fixing position
ensuring the Central Display is level. If you are
installing cable through the rear of the enclosure,
remove the knockout then fit a foam gasket over
its aperture to provide a seal against ingress.
CAUTION: TO PREVENT DAMAGE TO THE
FASCIA AND PRINTED CIRCUIT BOARD
(PCB), REMOVE THEM FROM THE ENCLOSURE BEFORE REMOVING KNOCKOUT.
Drill holes in the wall then fit wall plugs/dowels.
Fasten the lid of the enclosure to the base then
fix the Central Display in position. Install the
cables in position and cut them to length (HW).
Removing the knockout
To remove the knockout, place the enclosure
face down on a solid, non-slip surface. Tap the
knockout firmly using a hammer and punch. Use
pliers to remove sharp edges from the aperture.
2.1.2
Sensor
Retain the clear protective film on the fascia until
the installation is complete. Using the supplied
paper template mark out the wall-fixing position
ensuring the Sensor is level. (If installing a cable
through the rear, remove the knockout.)
WARNING: CARBON DIOXIDE GAS (CO2)
IS HEAVIER THAN AIR AND SHOULD BE
MONITORED FROM A LOW HEIGHT. YOU
SHOULD THEREFORE INSTALL THE CO2
SENSOR AT A HEIGHT OF 12–18" (305–
457MM) ABOVE THE FLOOR LEVEL.
WARNING: OXYGEN (O2) SENSORS
SHOULD BE INSTALLED AT AVERAGE
WORKING HEAD HEIGHT
Drill holes in wall, install wall plugs/dowels then
fit the Sensor. Install the cables in position and
cut them to length (HW).
2.1.3
Alarm
WARNING: LOCATE THE ALARM SO AS
TO PROVIDE COVERAGE FOR ACCESS
AND EGRESS POINTS AND BUSY AREAS.
Retain the clear protective film on the fascia until
the installation is complete.
Using the supplied paper template mark out the
wall-fixing position ensuring the Alarm is level.
(If installing a cable through the rear, remove
the knockout.)
Drill holes in wall, install wall plugs/dowels then
fit the Sensor. Install the cables in position and

Buzzer sounds briefly each time a button is pressed. Sounds continuously
for five seconds when using the TESTING ALARMS function. It sounds rapidly
on and off when an alarm is triggered, or once per second for a fault.

Under normal conditions the
indicator
flashes once per second to indicate that the
power is on and the unit is operating.
NOTE: THE SENSOR RECEIVES ITS
POWER FROM THE CENTRAL DISPLAY,
VIA THE CONNECTING CAT5E CABLE.
If the
indicator is off, this means the
Sensor is either not receiving power from the
Central Display, or the Sensor has a fault.
NOTE: CHECK THE CENTRAL DISPLAY;
IT MAY BE SHOWING A FAULT CODE.
If the
indicator lamp is on continuously,
this means that there is potentially a more
serious Sensor fault.
NOTE: CHECK THE CENTRAL DISPLAY;
IT MAY BE SHOWING A FAULT CODE.
If a Sensor is in fault, any Alarms connected
to it will also display a fault status (their
yellow
indicator LEDs will flash).
NOTE: FAULT CODES ARE DESCRIBED
IN DETAIL IN THE SERVICE MANUAL.
5.2.1
Sensor hardware settings
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 CO2 SENSOR 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 LOCATION 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.
