• Gas Zone
Lines configured as Gas Zone 4-20mA will generate “early warning” signals if the value of the
detector output exceeds 16mA. In order to implement the “early warning” signal, it must be enabled
(during the programming phase) on both the control panel and the zone the line belongs. The "early
warning" signal will stop automatically, if a gas detector exceeds the 12mA “early warning” threshold
then returns below this value without reaching the "alarm" threshold.
