VersAlarm Low-Level Tank Alarm with Outdoor Enclosure

The VersAlarm 4X 1-Zone Low-Level Tank Alarm from Alderon Industries is a reliable, outdoor-rated solution for monitoring water levels in cisterns, holding tanks, sump pits, pump chambers, and septic tanks. When your tank drops below the float switch position, the alarm triggers an audible buzzer and flashing red LEDs — giving you an early warning before you run dry.

Key Features

• Outdoor-rated NEMA 4X enclosure — suitable for exterior installation
• 120VAC powered with conduit connections (conduit required)
• Battery backup: install a 9VDC lithium battery (not included) for protection during power outages
• Audible buzzer + flashing red LED alarm indication
• Capacitive touch test/silence button — press and hold 1 second to silence buzzer during active alarm
• Auxiliary contacts for integration with building automation systems (BAS) and phone dialers
• Compatible with float switches, pressure switches, or any dry-contact normally open/closed sensor
• Optional pump terminal block available for pump power and switch connections in the same enclosure
• Low battery indicator: two quick pulses every 10 seconds

How It Works

When the float switch is activated (alarm condition), the red LEDs flash, the left green LED illuminates solid for zone indication, the buzzer pulses, and auxiliary contacts activate. The alarm stays active until the float switch deactivates and auto-resets for the next cycle. Test the alarm monthly to confirm system integrity.
