LeakageSensor (SystemPort) – MANUAL



The leakage sensor is used to monitor areas for leaks. A point sensor is attached to the underside of the leakage sensor for this purpose. For monitoring a larger area, the sensor can be supplied with an additional sensor cable. The sensor is connected to the SystemPort of a suitable remote station via the integrated 10-meter connection cable. All Kentix devices that are operated in one of the three operating modes Main, Sattelite or Stand-Alone Device are suitable as remote stations. In addition, the sensor offers the possibility to cascade up to 5 leakage sensors (series connection). In the event of a leak, the sensor provides feedback both optically and via the digital input of the remote station.

Detection and sensitivity

The housing sensor triggers an alarm even at small amounts of water of 1-2ml. The sensor cable requires approx. 10ml of water over a length of 20cm to trigger. Wetting can take place in several places, only the total wetting must be approx. 20cm.

Connection examples

Leakage sensor at SystemPort of remote terminal

Plug the connection cable of the leakage sensor into a SystemPort of the remote station. Power supply and alarming is done directly via the SystemPort.

The leakage sensor and the alarm behavior are configured via the integrated web server of the main device. Assign a suitable designation, such as “Leakage or water alarm” for the external alarm input 1 via the configuration of the remote station and set the alarm input to “Permanently active” for a permanent alarm. Additionally, change the alarm logic to “Alarmwhen open“.

The supplied 10m slimline cable can be replaced by a patch cable of max.  50m be replaced. !!! Only if the leakage sensor is connected directly to the remote terminal !!!!

Cascading of the leakage sensors

The leakage sensor offers the possibility to cascade up to 5 leakage sensors (series connection) and to operate them at one Kentix SystemPort. The connection is made via a standard patch cable and can also be integrated into structured cabling.

It is important to code the sensors appropriately as middle or end devices. For this purpose, there is a microswitch in the housing with which the coding can be set accordingly.

The distance between the remote terminal and the last Leakage sensor may Do not exceed 50 meters ! Longer distances can lead to signal loss.

Leakage sensor with sensor cable

The leakage sensor with sensor cable (KLS03-ROPE10/20) is a version of the standard leakage sensor KLS03 extended by a sensor cable. This makes it possible to monitor a floor area over a wide area. With this, the entire sensor cable serves as a detector, so you can detect leaks over a length of up to 20 meters with a single sensor. The sensor cable is typically laid in a meandering pattern, in loops, across the floor. The KLS03-ROPE10/20 functions in the same way as the KLS03. On the underside of the housing there are also the sensor electrodes for point detection. In addition, cascading of up to 5 KLS03(-ROPE) is possible if required.

The sensor cable of the KLS03-ROPE leakage sensor must be fixed to the floor. It is recommended to use the enclosed plastic dowel clamps for a hole of 6mm. The distance between the individual clamps should be between 30cm and 50cm. If it is not possible to drill a hole for the dowel clamps, the sensor cable can also be fixed with strips of high-quality adhesive tape. At the same intervals as the dowel fastening. It is important for both types of mounting that the sensor cable rests on the ground over its entire length.
