Alarm Key menu.
Alarms 1 and 2 are hard wired for the watchdog timer and service
alarms and are therefore not software-selectable.
NOTE
Oxygen and combustibles alarms are all disabled during a primary
or regular calibration. In addition, alarms are disabled during
start-up until the sensor reaches its proper operating temperature.
See the "Wiring" section in the Installation chapter for help on alarm
connections and how alarms are labeled on the control unit wiring card.
The Alarm key allows you to do the following:
Define whether Alarm 3 activates based on oxygen levels, the start of
a calibration, or the start of a verification (Select Function). All other
alarms are set to activate based on only a single condition; for Alarm
4 this condition is levels of oxygen, for Alarms 5 and 6 this condition
is high combustible levels (% or PPM scale).
