EX2GSI

In the EXFIRE360 fire alarm panel, EX2GSI is the independent control unit for the detection of flammable gases, toxic gases or oxygen.

It can be also utilized in fire alarm systems to monitor analog detectors (e.g. flame detectors with 4-20 mA proportional output), as described in Chapter 6.

Regarding the flammable gas detection, EX2GSI card refers to standard EN 60079-29-1; when used for fire detection, EN 54-2 requirements must be met.

EX2GSI is equipped with two 4-20 mA analog inputs (with internally redundant channels and configurable prealarm/alarm thresholds), two supervised outputs (rated 24 Vdc, 2 A max, for shut-off valves, notification appliances, etc.), two volt-free relays (rated 24 Vdc, 2 A max) and seven Open Collector outputs that can be associated to pre-alarm, alarm or fault conditions of both inputs.

The card must be connected to continuous duty apparatus that can provide a 4-20 mA analog output, fully monitored while operating.

EX2GSI has a standard Eurocard format (160 mm x 100 mm) with a rear plug connector to 19” rack and it’s integrated in the communication bus of the panel.
