The standard beeping tone is also an indication of sensitivity level.
- In HIGH sensitivity the unit emits two quick beeps approximately once every two (2)
seconds, in fresh air.
- In LOW sensitivity the unit emits only one beep, approximately once every two (2)
seconds, in fresh air.
Sensor Status Indicator
The unit’s circuit has the ability to automatically diagnose and indicate the sensor’s
status. Whenever the unit is energized, the circuit automatically senses the condition
of the sensor and can detect a failed or missing sensor.
Old Sensor Indication: As the sensor ages, the circuit will note and indicate this to the
user. Initially, an Old Sensor Indication is displayed by flashing the Constant Power
Indicator. If this indication appears, it is time to obtain a replacement sensor. Refer to
the Replacement Parts section. However, it is not necessary to replace the sensor
before the Failed Sensor Indication is received.
Failed Sensor Indication: If the circuit detects a failed or missing sensor, the 2nd
through 6th LEDs turn red and flash quickly. The 1st LED continues to display the
battery status as described earlier. Additionally, the internal pump shuts down to
prevent unnecessary battery drain. If this indication appears, refer to the Maintenance
section for service instructions.
Audible / Visual Alarms – Mute Feature
The unit features two primary alarm indications – an internal speaker that produces a
multiple frequency tone, and a series of tri-color LEDs that provide an incremental
indication of leak detection and proportional leak size.
You may choose to activate both the audible and visual alarms, or use only the visual
alarm. Upon power-on, the unit will activate both. If you wish to cancel or “mute” the
audible alarm, press the Alarm Key .
This mutes the internal speaker, and detection will be indicated solely by the LED
display. Press the Alarm Key again, at any time, to reactivate the internal speaker.
The LEDs provide a tri-color, proportional indication of leak intensity. The 2nd through
6th LEDs are used for this indication, while the 1st LED always remains an indication
of battery strength. See Figure 5.
