Description
Flushing systems require maintenance disconnect switches and often require abort switches. These maintenance and interruption switches are clearly labeled and combine easy operation with rugged construction for high integrity operation.
Abort switches provide 2080-9057 a request for manual release abort of the fire suppression system:
- The momentary push button switch is mounted on a single gang stainless steel plate
- A protruding collar protects the switch from accidental contact (collar can be removed if necessary)
- Flush or surface mounting available
- Flush mounting requires a standard single-gang box
- Surface mount includes a red mounting box
- Models are available with a 1.2 kΩ internal resistor for current-limiting operation.
