FPT50 – Fire Service Water Tank Level Control with High & Low Alarms

Complete Kit Includes:

Sensor With 50 ft. Sensor Wire, Controller, Mounting Assembly


  • Dry contacts to BMS for measuring Fill “ON” time
  • Low Water Alarm
  • High Water Alarm
  • Fault conditions
  • Optional temperature signal @ 40°F per NFPA
  • Optional Paragon Valve – Fill operates automatically during power loss
  • Operates 110VAC Solenoid Valve
  • Two 110VAC 95db Audible Alarm w/ Silencer Switches Installed in the Panel


The system is automatically controlled within an operating range (this range can be set by custom ordered probes or cutting the current probes to length in the field). The system also monitors for a high water level condition and a low water level condition.

These conditions have three outputs each which are:

  1. Close a set of dry contacts for the BMS
  2. Operate a relay rated at 30AMPS / 250VAC
  3. Turn on an LED to indicate the sensor has tripped

The Fill dry contacts can be used as a comparative to develop a baseline benchmark of water usage for the system.

Custom Sensors lengths available upon request.
