The Geopal GP-SA-2 is a 230VAC version of our well-known GP-SA stand-alone detector. The GP-SA-2 detector uses an integrated microprocessor for continuously monitoring the gas concentration, whether it is in the 0-100% LEL range (lower explosion level) or the 0-40,000 ppm range, in connection with e.g. refrigerants.
A new feature is the “service switch”. Using the service switch the alarm relays are deactivated and the fault relay is activated. This makes service much easier and no false alarms will be sent to the external system. The fault relay is active during service as an indicator for the technician to activate the gas detector before leaving site.
The signals of the Geopal GP-SA-2 detector are converted to a linear output signal of 4-20mA or 0-5/10V and the detector is equipped with alarm relays for low alarm, high alarm and system fault.
