Water leak sensor WLD Relay 1W-UNI, 1 zone up to 185 m, relay output and RJ11, plain unit - HW group 600513

Not every leak detection point needs its own network device. The WLD Relay 1W-UNI connects one leak detection zone with up to 185 m of cable to existing HW group units as a standard sensor, or works on its own and switches a relay, for example into an alarm panel or building management system.

Benefits

• Two operating modes: RJ11 sensor powered by the host unit, or standalone with 12 V and relay output.
• NO/NC relay output rated 50 V and 1 A signals OK, water and cable disconnected.
• Several zones on one unit: multiple WLD Relay sensors can run on a single Poseidon or Ares device.
• Early warning: a few drops of water, ethylene glycol or other conductive liquid on the sensing cable trigger the alarm.
• Long-term stable detection, with no bend, twist or grip limits on the sensing cable.
• Low consumption: 20 mA at 9-15 V, 40 mA on the RJ11 port.

Applications

• Water detector for security and alarm systems via the relay output
• Water detection under raised floors in server rooms
• Leak monitoring on pipes and cooling circuits, cable wrapped around the pipe
• Drip trays and air-conditioning outlets
• Protection against water entering through skylights, cable routed along the walls

Compatibility

• HW group units with RJ11 sensor port (1W-UNI), e.g. STE2, Poseidon2, HWg-Ares, Perseus
• WLD sensing cable type A, e.g. packages with connecting cable HW group 600417, 600467, 600468
