The Power unit will give an audible and visual alarm when either the clogging of the filter(s) causes the airflow to drop to the minimum design flow
rate or when the battery voltage drops to a level below which it could not safely power the Power unit. When either of these conditions occur a
frequently repeating audible bleep is emitted and in addition the yellow LED on the top of the Power unit flashes if the filter is clogged or the red
LED flashes if the battery is low.
When either alarm condition occurs during use the wearer should leave the contaminated area immediately and replace the filter or recharge the
battery accordingly.
When first turning the unit on the alarm will beep to indicate the correct functioning of the alarm system. If the beep stops after a few seconds the
airflow is sufficient to proceed with using the unit.
When Used With Full facemask. ( clockwise setting )
The Power unit is designed to exceed the requirements of EN12942 TM3 in that it will provide a minimum design flow rate of at 95 litres/min
when used with a full-face mask. for at least 4 hours under all conditions, assuming a fully charged battery at start. (Minimum design duration =
4 hours). Typical battery duration depends on a number of factors but is usually around 8 Hrs.
The Power unit will give an audible and visual alarm when the battery voltage drops to a level below which it could not safely power the unit.
When this condition occurs a frequently repeating audible bleep is emitted and in addition the Red LED on the top of the Power unit flashes.
When the alarm condition occurs during use the wearer should leave the contaminated area immediately and recharge the battery. The
electronic clogged filter low flow alarm is not enabled on the full-face mask setting. An airflow indicator is provided with the unit, which can be
used to check the flow prior to the use of the unit.
To check the airflow for full facemasks ensure that the filter and battery are fitted and turn the power unit on. The head piece hose should not
be fitted. Insert the airflow indicator into the outlet of the power unit with the letters on the label upright (See diagram I on page 6) and the label
facing toward the front of the unit (where the filter is fitted). If line A is fully visible then the unit has sufficient airflow. If line A is not visible
replace the filters. If you have both replaced the filter and fully charged the battery and line A is still not visible the unit and battery should be
returned to the supplier.
