The REEFE Liquid Level Alarms are designed to provide warning indication when a storage tank is either empty or full. The buzzer can be muted via a mute button. If not muted the audible buzzer will continue to run. The visual and audible alarms will continue to remain on, until the alarm condition is resolved. A standard feature of the Level Alarm is a ‘Voltage Free’ (5 amp rated) output for connection to auxiliary devices. Controller can be installed up to 50m from the tank being monitored. Float switch cabling is ‘safe’, low voltage circuitry. Warning indication is determined by a float switch. Warnings are Audio (buzzer) and Visual (LED Pilot Light and / or Strobe)
