The gas detection indicator and alarm unit can monitor a variety of gas detector models for monitoring toxic and combustible gases and oxygen. Each gas detector is connected to an individual indicator unit. Indicator units can work stand alone with their own build in set of alarm relays, but also in combination with a common alarm unit (VAS) and relays. Gas concentrations are clearly indicated on a 50 segment 3 colour LED bar graph for each channel. The V3 series indicator and alarm unit is suitable for many small, mid to large-size gas detection systems for applications in many industries. |
Features
- Easy to notice the alarm status with 3-color LED display.
- Maintenance Mode which will stop the alarm output to external devices during the maintenance, to allow a maintenance work alone.
- It can be replaced in the existing COSMOS gas detection system due to the failures.
- The cover attachment of PCB makes safe to use.
- The switch cover prevents accidental operation.
- The switch cover for alarm unit can also be selected (option).
Accessories
- Single case cover
