HW group: WLD-ECHO

Water-leak alarm for two sensing zones

WLD-ECHO monitors two zones with Type A or B WLD sensing cables for water and other conductive liquids. When a leak is detected, it provides an audible alarm, LED indication and a dry-contact relay output. A disconnected or damaged sensing cable is also indicated, and the second zone can be disabled when unused. Each zone supports a total length of up to 185 m including connecting and extension cables. Power is provided by two AA batteries or an external 5–30 V DC supply, nominally 12 V. The relay output is rated for 25 V and 0.5 A. The device is intended for indoor use at −10 to +60 °C. This device-only version is supplied without sensing cables, batteries or a power adapter.
