BWA20 Bilge Water Alarm
The BWA-20 Electronic Bilge Water Alarm
uses modern electronics and a reliable solid state stainless steel water
sensor to monitor your bilge for the presence of water. If the sensor detects
water continuously for more than 15 seconds it sounds a built-in 85 dB
The alarm will continue to sound
as long as the sensor detects that water is continuously present in the
bilge, or until the reset button is pressed. If the alarm is silenced by
the use of the reset button, the BWA-20 will automatically arm itself again
as soon as the water has subsided.
A 15 second timer is started when
the BWA-20 detects water. If contact is broken with the water for even
a moment, the 15 second timer will reset and start over. This prevents
false alarms due to a small quantity of water sloshing in the bilge due
to boat motion.
The BWA-20 operates from a standard
9V transistor radio battery for one year and will run for two years (or
longer) from an alkaline 9V battery. The BWA-20 has a built-in low battery
warning system that tells you if the battery needs changing by chirping
briefly every few minutes.
