Sensor Missing Alarm; Caution; Warning - MSA Sirius Operating Manual

• Alarm sounds and lights flash
• Alarm can be silenced by pressing the RESET/
• No other pages can be viewed
• After approximately one minute, the instrument automatically
turns OFF.
When Battery Shutdown condition sounds, stop using the
instrument; it can no longer alert you of potential hazards
since it does not have enough power to operate properly:
1. Leave the area immediately.
2. Turn OFF the instrument if it is ON.
3. Report to the person responsible for maintenance
4. Recharge or replace the battery.
Failure to follow this procedure could result in serious per-
sonal injury or death.
During "Battery Warning" condition, prepare to exit the work
area since the instrument could go into "Battery Shutdown"
at any time, resulting in loss of sensor function. Depending
on the age of the batteries, ambient temperature and other
conditions, the instrument "Battery Warning" and "Battery
Shutdown" times could be shorter than anticipated.
Recharge or replace the battery when the "Battery Warning"
or "Battery Shutdown" conditions occur.
Recharging or replacing batteries must be done in a non-
hazardous location only.

is checked when the instrument is turned ON and when leaving the
Setup mode. The combustible Sensor Missing feature is continually
monitored. If a sensor is detected as missing, the following occurs:
