The Aqualarm OFDi-485 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 the 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 status and monitoring is via a single RS485 link to an i-Zone Mini control panel.
