Indicator Unit
V3-Series
Features
- Easy to notice the alarm status with 3 color LED display
- Maintenance mode which will stop the alarm output to external system devices during the maintenance to allow a maintenance work alone
- it can be raplace 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).
