Model: FSBS Flowswitch Bypass Switch

Category: Fire protection

Type: Owner's manual

Potter FSBS Flowswitch Bypass Switch allows sprinkler systems to be filled without activating local waterflow alarms or fire panels. It eliminates the need for coordinating schedules with alarm companies and sprinkler technicians. Compatible with any flowswitch, local indicating appliance, and fire panel, it features a key-operated switch to prevent unauthorized use and provides visual indication of the selected mode (Normal or Bypass) and the status of the monitored flowswitch. It is suitable for use in NFPA 13, 2016, A.6.8.4 applications.
