The QuadGard control system is suitable for one to four gas detectors; either two or three wire transmitters, toxic or Ex, mA or mV. There are three alarms per gas detector, and these alarms can be individual, common, or voted; rising, falling and/or latching.


With its easy-to-use, password-protected menu structure, the system can be adapted to any customer-specific requirements. The settings for the connected transmitters and gases are entered via the integrated keypad. The gas concentration can be read from the 2-line LCD display. All of the status information is clearly arranged. LEDs in different colours give a quick overview over the current status of the equipment (e.g. power supply on, alarm raised, fault detected).


With its robust, wall-mounted enclosure, the QuadGard conforms to protection class IP65 and is therefore also suitable for outdoor use.
