9. Alarm Overview
The POLI provides an unmistakable five-way alarm notification that combines local
alarms on the device with real-time remote wireless alarm notification to enhance worker
safety up to the next level. Local alarms include audible buzzer alarm, visible alarm via
bright LED lights, vibration alarm, and an alarm notification on the display. These can be
programmed or selectively turned on or off.
9.1 Alarm Signals
During each measurement period, the gas concentration is compared with the
programmed alarm limits for Low, High, TWA and STEL alarms. If the concentration
exceeds any of the preset limits, the alarms are activated immediately to warn both the
POLI user and a remote safety officer (if wireless is enabled) of the alarm condition.
In addition, the POLI alarms when the battery voltage is low, pump is blocked, etc.
When a low-battery alarm occurs, there may be approximately 10 minutes of operating
time remaining. However, it is recommended that you promptly change using a fully
charged POLI or charge the battery in a non-hazardous location.
9.2 Testing Alarms
Under normal operation mode and non-alarm conditions, the audible, visual, and
vibration alarms can be tested at any time by pressing the [OK] key.
