Alarm Lights
The 01 Series has two red LED alarm lights. They alert you to gas, low
battery, and sensor failure alarms. The smaller of the two lights is square,
has a frosted plastic cover, and is located at the top of the unit to the left of
the membrane retainer. The larger alarm light is rectangular in shape, has
a diamond-grid pattern etched into the plastic cover, and is located to the
left of the LCD on the front of the case.
Buzzer
A solid-state electronic buzzer is mounted inside the 01 Series. An opening
in the sensor retainer on top of the case allows the buzzer’s sound to
emanate from the case. The buzzer sounds for gas alarms, unit
malfunctions, and dead battery alarm. It also serves as an indicator during
normal use of the various LCD display options.
Vibrator
A vibrating motor (vibrator) is mounted inside the 01 Series. The vibrator
vibrates momentarily during the power-up sequence and for gas alarms.
Batteries
Two AAA-size alkaline batteries run the 01 Series. At 25°C the alkaline
batteries last at least 3,000 hours. The battery icon on the LCD shows
remaining battery life.
When the 01 Series detects low battery voltage, a low battery warning is
activated. When battery voltage is too low for normal operation, the 01
Series sounds a dead battery alarm.
The alkaline batteries can be replaced by removing the battery door at the
bottom of the case. Turn the captive battery cover screw counterclockwise
to release the door.
WARNING: To prevent ignition of a hazardous atmosphere, batteries
must only be changed in an area known to be
