Description

CO Fault Mode timer

Only if you install the CO Sensor

The factory default setting is disable. Use

the 

UP

 or 

DOWN

 buttons to set the CO Fault

Mode timer to disable, 3, 4, 5, 6 years or

reset.

When disabled, the device does not sound

the buzzer or provide LCD and status

LED indication when the CO sensor life is

exceeded. When set to 3, 4, 5 or 6 years, the

fault alarm activates to indicate that the CO

sensor life is exceeded.

If set to reset and you press 

MENU

, the

fault condition for the CO sensor clears, the

CO life-time timer resets, and the CO Fault

Mode remains at the previous setting. The

timer automatically resets if you replace the

CO sensor. If the required time has already

been exceeded, it cannot be selected.

NO

2

 Fault Mode timer

Only if you install the NO

2

 sensor

The factory default setting is disable. Use

the 

UP

 or 

DOWN

 buttons to set the NO

2

Fault Mode timer to disable, 1, 2, 3, 4 years

or reset.

When disabled, the device does not sound

the buzzer or provide LCD and status LED

indication when the NOsensor reaches end-

of-life. When set to 1, 2, 3. or 4 years, the

fault alarm activates to indicate that the NO

2

sensor life is exceeded. If set to reset and

you press the 

MENU

, the fault condition for

the NO

2

 sensor clears, the NO

2

 lifetime timer

is reset and NO

2

 Fault Mode remains at the

previous setting. The timer is automatically

reset if the NO

2

 sensor is replaced. If the

required time has already been exceeded, it

cannot be selected.

CO recal mode

Only if you install the CO Sensor

The default setting is 1 year. Use the 

UP

 or

DOWN

 buttons to set the CO recalibration

mode timer to disable, 1, 2, 3 years, or reset.

When disabled, the device does not sound

the buzzer or provide LCD and status LED

indication when the CO sensor requires

recalibration. When set to 1, 2, or 3 years,

the ReCal alarm activates to indicate that the

CO sensor requires recalibration.

If set to reset and you press 

MENU

, the

ReCal condition for the CO sensor clears,

the CO ReCal timer resets and the CO ReCal

mode remains at the previous setting. The

timer automatically resets if you replace the

CO sensor. If the required time has already

been exceeded, it cannot be selected. If the

CO sensor is calibrated with gas through the

MENU

, the timer automatically resets.
