1.1
Purpose of the Ax60K
The Ax60K is a life-safety device that measures the amount of carbon dioxide (CO
2
) in
the air. It is designed for street kiosks and small restaurants which use pressurised CO
2
to dispense carbonated drinks. The Ax60K has a built-in gas detector that continuously
monitors the atmosphere and triggers an alarm if it detects a high level of CO
2
. Alarms
are displayed by an indicator lamp, a buzzer, a strobe light and a high-volume sounder.
CO
2
Alarm
The CO
2
Alarm has a high-visibility flashing
strobe light and a high volume sounder. These
give visible and audible warnings of increased
levels of carbon dioxide detected by the CO
2
Sensor. The warnings vary, depending on the
amount of CO
2
detected. The power supply to
the CO
2
Alarm is provided by the CO
2
Sensor.
CO
2
Sensor
The CO
2
Sensor constantly monitors the air and
detects increases in the level of carbon dioxide.
If the CO
2
Sensor detects a level of CO
2
above
set limits it sends a signal to the CO
2
Alarm. The
CO
2
Sensor supplies power to the CO
2
Alarm.
Power supply unit
The power supply unit (PSU) supplies 24V DC
power to the CO
2
Sensor.
Cables and coupler
The CO
2
Sensor and CO
2
Alarm are pre-wired
with 2-metre connecting cables. A cable coupler
is supplied to allow the cables to be connected.
1.2
The dangers of CO
2
Fresh air contains a safe level of CO
2
, 0.04% or 400ppm (parts per million). An increase
to 1.5% (15,000ppm) causes drowsiness, headache and increased breathing. A level of
3% (30,000ppm) causes dizziness. 10% (100,000ppm) will cause unconsciousness and
eventually death. CO
2
is odourless and colourless and is not detected by human senses.
There is a danger to health wherever pressurised or concentrated CO
2
is stored or used.
1.3
Ax60K alarm settings
The Ax60K has three alarm settings which are factory set:
Time-weighted average (TWA) alarm. This is triggered by a CO
2
level of 5000 ppm
(0.5%) detected over the previous 8 hours. A TWA alarm is announced on the CO
2
Sensor only (flashing red indicator LED and internal buzzer).
Low alarm. This is triggered by 15,000ppm (1.5%) CO
2
. A low alarm is announced
by both the CO
2
Sensor (flashing red indicator LED and internal buzzer) and the CO
2
Alarm (high-visibility strobe).
High alarm. This is triggered by 30,000ppm (3%) CO
2
. A high alarm is announced
by the CO
2
Sensor (flashing red indicator LED and internal buzzer) and the CO
2
Alarm (strobe light and sounder).
