Water Alarm (optional)
If you have the optional water alarm installed there are three alarm conditions to know:
Condition
LED
Siren
New Battery
(Insertion)
Bright Intense blink
while siren plays
Ascending tones played 4 times
Water Intrusion
Bright Intense Blink
Grating Warble sound. Alarm will sound
for duration of detection.
Low Battery
Low Intensity fast blink
Descending tones played 8 times
pausing approx. 20 seconds between.
The alarm can be tested by shorting the detection contacts that lead to the water alarm
transducer. The water detection condition will activate for 6 seconds. If the battery is
drained the low battery condition will sound.
The water alarm requires a single 6V battery like Radio Shack model 23-469 or A544.
Your battery should be removed when stored (e.g. between dive trips). Check the
battery prior to every die to ensure proper operation. Change when indicated.
CAUTION
: You must wait a minimum of 30 seconds between battery insertions to allow
the unit to fully discharge.
Water Alarm LED will
illuminate here on the
right side of the Rear
Shell.
