Zoeller 10-4490 High Level Alarm Audio Visual 115V AC

SKU CH-XH8X-21E3D

High-level water alarm with audio and visual alerts, 87 dB siren, 16 ft sensor cord, and battery backup for sump pump basins

  • Audio and visual alerts warn of high water
  • 87 dB siren cuts through ambient noise
  • 16 ft tethered float detects rising levels
  • 6 ft power cord reaches standard outlets
  • Manual reset prevents automatic restart

Purpose and fit

The Zoeller 10-4490 is a high-level alarm for sump pump basins that sounds and flashes when liquid reaches a critical point. It is intended for indoor residential or light-commercial installations where early warning of pump failure prevents water damage.

Capacity and headroom

A tethered float on a 16 ft cord detects the high level while the 6 ft power cord reaches a standard 115V AC outlet. The alarm draws 0.5 A and produces an 87 dB tone alongside a visual indicator. Battery backup keeps the alert active during a power outage, but the NEMA 1 enclosure limits use to dry indoor locations.

Deciding specification

The detection type is high level only, so the unit cannot signal a low-level or dry-run condition. Buyers who need low-level notification or a latching alarm with automatic reset will require a different device.

Highlights

  • Audio and visual alerts warn of high water
  • 87 dB siren cuts through ambient noise
  • 16 ft tethered float detects rising levels

Questions about this item

Will the 16 ft sensor cord reach my existing sump basin if the alarm is mounted on a nearby wall?

The tethered float includes a 16 ft cord, so you can position the alarm up to that distance from the basin while keeping the float inside the pump chamber.

How do I confirm the 87 dB audio and visual signals are active after wiring the 115V AC unit?

Raise the tethered float manually until the alarm triggers; both the audible horn and the indicator light should activate, showing the high-level detection is working.

Does the box contain the tethered float and 6 ft power cord, or must I buy them separately?

The package includes the tethered float and a 6 ft power cord; no extra parts are required for a standard indoor installation.
