GasWatch 2 Operator’s Manual Description • 8
Alarm Lights
The GasWatch 2 has two alarm lights located above the LCD. The alarm
lights are two red LEDs that alert you to gas, low battery, and sensor failure
alarms. They are visible through a frosted lens.
Buzzer
A solid-state electronic buzzer is mounted inside the GasWatch 2. An
opening on the left side of the top case allows the buzzer’s sound to
resonate from the case. The buzzer sounds for gas alarms, unit
malfunctions, low battery voltage, and as an indicator during normal use of
the various display options of the GasWatch 2.
Vibrator
A vibrating motor (vibrator) is mounted inside the GasWatch 2. The vibrator
vibrates momentarily during the power-up sequence and for gas alarms.
Lithium Battery
A 3.0 volt coin type lithium battery powers the GasWatch 2. The battery will
run the unit for approximately 3,000 hours when no alarms have been
activated during that time period. The battery icon on the LCD shows the
charge remaining in the battery. When the GasWatch 2 detects a low
battery voltage, a low battery warning is activated. When the GasWatch 2
determines that the battery is too low for normal operation, a dead battery
alarm is activated. The battery can be replaced by removing the battery
door in the bottom case. See the maintenance section of this manual for
instructions about replacing the battery.
