Leak Detection

WC cistem overflow sensor (¾" male BSP)

The AT-450A toilet overflow sensor allows the monitor of individual cistern overflows. The sensor is wired to one of the single or multi zone alarm panels. In the event of an overflow condition arising a local alarm will be generated together with a general alarm to the BMS.

• The system is designed to alert building management personnel with an audible and visual warning, to the wasteful discharge of overflowing water, directly to WC pans, by ‘internal WC cistern overflows’.
• A sensor is inserted into the overflow hole at the side of concealed WC cisterns that incorporate an internal overflow arrangement discharging to the WC pan.
• The sensor detection level can be set to occur at a point when an overflow situation is imminent but before water is wastefully discharged to the WC pan.
  Sensors are available for standard concealed and Geberit type WC cisterns
