Alarm disable function

Three digit indicator serves as both a power on indicator and
a direct reading display of the gas concentration. The display
will also flash on and off during any over-range condition.

Alarm set points are dip switch adjustable in 1 ppm/%
increments across the range of detection. Programmable jumpers
allow for several user selectable alarm options.

The fault alarm, depending on the jumper programmable
configuration, will activate on loss of power, internal power
supply fault, open circuit in field wiring, open heater/bridge
in sensor, or during an alarm disable condition.

The alarm disable function inhibits alarm relays (Alarm 1, 2
and 3), but leaves alarm LEDs active. The alarm disable
function will also activate the fault LED and relay, however,
no other Model 12 functions are af fected. The toggle type
switch is inset slightly behind the front panel in order to
prevent accidental disabling of the channel.

The alarm reset switch resets alarms that have been jumper
programmed latching. It also acts as a test switch to activate
several microprocessor supervised test functions.
