4.2 ATMOSPHERIC ALARM CONDITIONS
CAUTION
The Impact portable gas detector has been designed for
the detection of oxygen deficiencies and enrichments,
flammable gas and toxic gas levels. An alarm condition
indicating the presence of one or more of these potentially
life-threatening hazards should be taken seriously.
In the event of an alarm is activated when the measured
gas concentration exceeds the pre-set alarm point.
A rapid increase in reading followed by a declining or
erratic reading may indicate a hazardous combustible gas
concentration that exceeds the measuring range of the
Impact (i.e. greater than 100%LEL or 5.0%v/v Methane).
In the event of the instrument being exposed to a very high
level of flammable gas the following behaviour will be
noted.
• Warning 54 (Low O
2
) and an alarm condition will be
indicated. This warning will be latched.
• Warning 52 (sensor over-range) and an alarm
condition will be indicated.
• The flammable reading will be latched to 100%LEL or
5.0%v/v Methane with an alternating cross on the
channel.
For other sensors reading greater than the measurement
range, ‘
!!!’ will be displayed.
