The GA-1 and GA-2 alarm systems are specifically designed for grease separators. They indicate when it is time to empty the grease separator, thus preventing possible problems in the sewer system.
The system consists of the GA-1 or GA-2 control unit and the GA-HLL1 and/or GA-SG1 sensors installed in the grease separator. They monitor the level by means of a capacitive measurement. The sensor cable can be extended with a cable coupler or junction box up to a maximum of 100 metres.
The installation of this type of warning system ensures that the separator complies with the requirements of the EN 858-1&2 standards, which stipulate that oil separators must be fitted with alarms.
Both the sensors and the control unit cannot be installed in a zone 0 explosive atmosphere and should always be installed in a safe area.
