Gas Alarm Conditions and Advice

If the current gas concentration meets or exceeds either alarm setpoint, the GasPoint gas alarm functions will

activate.

Note: If both or either gas alarm is turned OFF (set to zero or set to the same value) then no gas alarm condition

will exist for that alarm level.

The following alarm advice will activate in any gas alarm condition (LOW or HIGH):

The backlight will activate.

The 4-20 mA loop output will be normal (from 4 to 20 mA according to calibrated values)..

When the alarm condition no longer exists, GasPoint will exit alarm mode and enter normal operations.

Exception: If a relay is set to the latching position on either Low or High gas alarm, the relay will

remain “on” until the alarm is reset (ACKNOWLEDGED). Press the external button to reset the relay.

O2 (Oxygen) Note: (See Oxygen note 1 on page 13) An oxygen alarm level will depend on which

alarm setpoints have been set to Low and High. The

oxygen Low and/or High gas alarm setpoints are user

selectable for either enrichment and/or deficiency alarms as desired.

CAUTION: HIGH OFF-SCALE READINGS MAY INDICATE AN EXPLOSIVE CONCENTRATION.
