Bump Test
for more information. If the pump test is successful,
the detector returns to normal operation, otherwise the pump alarm con-
tinues. If the pump alarm persists, refer to the Pump Operation section in
.
Low Battery Alarm
The detector tests the batteries upon activation and continuously
thereafter. Battery power is continually displayed during normal
operation. If the battery voltage is low, the detector activates the
low battery alarm.
The low battery alarm continues until the batteries are replaced/charged,
or until the battery power is almost depleted. If the battery voltage
becomes too low, the detector deactivates.
Note
Typically, the low battery alarm continues for 30 minutes before
the detector automatically deactivates.
Automatic Deactivation Alarm
If the battery voltage is in immediate danger of falling below the minimum
operating voltage, the audible alarm beeps eight times and the visual
alarm flashes eight times. After 3 seconds, the LCD dims and the
detector deactivates.
To replace or charge the batteries, refer to the following sections:
•
Replacing the Alkaline Batteries
•
Replacing the Lithium Battery Pack
Bump Test
A bump test is the process of applying a small amount of test gas to
force the detector into alarm. A bump test should be performed regularly
to confirm the sensors are responding correctly to gas, and that the audi-
ble, visual, and vibrator alarms activate during an alarm condition. Cali-
brate if the readings are not within specified limits.
Performing a Bump Test
a
Caution
BW recommends to bump test the sensors before each
day’s use to confirm their ability to respond to gas by
exposing the sensors to a gas concentration that
exceeds the alarm setpoints.
To perform a manual bump test refer to
Applying Gas to the Sensors on
and the following steps 1-6. Follow this procedure when Bump
Daily is enabled.
Note
The Calibration icon will flash if a sensor has failed a bump
test.
Note
If performing a bump test on a pump unit, connect the calibra-
tion hose directly to the pump module.
