2. RELAY MODULE FUNCTIONING
The stand-alone detectors STANDGAS HC and STANDGAS HC PRO are provided of a relay output with the following
parameters:
1
Idle mode relay. It allows to select an activated relay without alarm, or a deactivated relay.
2
Relay disconnection type. It allows to select the instantaneous disconnection of the relay once alarm condition is over or
if retard selected is used.
