ASG-2002HV Autonomous gas detector LPG (propane-butane), external DC power ~230 V AC.
Autonomous ASG-2002HV gas detectors range ASG-2000 are designed to detect flammable and toxic gases in hazardous areas such as garage, car parking and boiler room etc. When the particular threshold is exceeded, the detector’s optical indicator is activated and appropriate outputs for controlling the external sounder beacon are activate
Microprocessor detector measurement systems continuously analyze the gas concentration in the room and compare it with the values of the relevant alarm thresholds. Each detector has got three alarm thresholds, strictly related to a defined gas concentration in the air. When the particular threshold is exceeded, the detector’s optical indicator is activated and appropriate outputs for controlling the external sounder beacon are activated. A failure states (detector’s failure, sensore’s failure, power failure, no sensor module) are signaled by a separate LED and a programmable relay output.
