Indicator Unit / Alarm Unit V3 series
-
-
- Model
- V3 series
- Type
- Hv、Hi、Cv、Ci、Tv、Ti、D、O、M
- Gas Concentration Display
- 3-color LED bar graph (50 split)
Indicator unit, alarm unit and communication unit to combine with each gas detector head.
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).
