Newton High Water Alarm (PA50)

Provides alarm function for single or twin pump systems where no control panel is installed.


The Newton High Level Water Alarm (PA50) has been designed to detect high water levels within pump sump chambers, and is included within the Newton Titan-Pro and Newton Titan pumping systems. The alarm is powered by a standard 9 V PP3 battery.

It can be programmed to automatic reset or manual reset after an alarm occurrence. A mute button to the front face silences the alarm once the alarm condition is discovered. A flashing alarm light gives visual indication of an alarm condition, and this light will continue to show even when the alarm sounder is muted.

When the unit is to be used within a single pump system, the alarm switch should be positioned just above the point where the single pump should start pumping. When used within a twin pump system, the switch should be set at a height above the point of the start of the lower pump but below the point where the secondary pump would ordinarily start.

Features and benefits:

  • The alarm sound reaches 90 dB.
  • Includes auto or manual reset options.
  • Can be either surface mounted or flush mounted to a standard electric black box.
  • Includes a 5 m float cable, and mute and test buttons.
  • Zero voltage output is used to notify the Newton Text and Speech Dialer or BMS (Building Management System) of an alarm occurrence.
  • Supplied with a one-year back-to-base warranty which is dated from either the date of purchase or a proven date of installation.
