The Aqualarm OFDi-24 overflow detector is made up of two components: the detector module and the overflow detector, connected via a 2m jumper cable.

Both the detector module and overflow detector are manufactured from STAREX General ABS (SD-0150) plastic.

The bottom of the overflow detector is fitted with a ¾” BSP threaded connector with two stainless steel sensing probes extending from the end. The connector should be inserted into a ‘tee’ to enable the probes to sense any water passing through the main overflow pipe.

A red LED is incorporated onto the detector module, and will glow to indicate the detection of water.

Alarm monitoring and status is via a network, using a CAN bus system.

  • For detection of water within an overflow pipe
  • ¾” BSP threaded connector for insertion into a tee piece
  • Manufactured from rust-proof and hard-wearing ABS plastic
  • Two component design - keeping head and electronic module separate
  • LED and internal alarm sounder in module to give local alarm indication
  • For connection to i-Zone or i-Zone Touch control panels
