Aqua-Scanner SHT 5020

The Sensor Cable Scanner for Area-Wide Water Monitoring: Water is Detected Along the Entire Sensor Path, for Schabus Water Alarms

The Schabus Aqua-Scanner SHT 5020 complements point-type water sensors. Its 2 m long sensor cable detects conductive water along the entire sensitive section. It is laid where water can escape and spread, for example under kitchen and bathroom furniture, along pipelines or under water-carrying systems.

The principle is simple: When water reaches the sensor cable and creates a sufficiently conductive connection between the sensor elements, the connected Schabus water alarm detects this change and triggers an alarm according to its settings. The Aqua-Scanner thus monitors entire areas and paths, not just individual low points.

The SHT 5020 is an accessory for the Schabus water alarms SHT 5000 and SHT 5001 and is supplied with a 2 m sensor cable and a 1 m permanently connected LIYY connection cable. The sensor itself operates passively and does not emit its own alarm.

⚠️

Important note: The SHT 5020 is intended for normally dry installation locations. It is not suitable for permanently flooded areas or continuous liquid exposure. It may only be connected to a suitable sensor input of a water alarm, never directly to a supply voltage or an electrical load.

💡

Good to know: The Aqua-Scanner reports water but does not indicate at which point on the sensor cable the wetting has occurred. It is not locating. Evaluation and the desired response are handled by the connected water alarm.

One Sensor Path Instead of a Single Measuring Point

The SHT 5020 combines a robust, metal-free sensor cable with a connection cable that fits directly to the Schabus water alarms.

📏

Area-Wide Monitoring

The 2 m long sensor cable detects water at any point along its sensitive path.

🧵

What's in the Box

The SHT 5020 is ready for immediate use. The device has no options and no additional variants.

  • Aqua-Scanner SHT 5020
  • 2 m sensor cable
  • 1 m LIYY control cable, 2 × 0.14 mm², permanently connected
  • Operating instructions

Sensor cable and connection cable are permanently connected; nothing needs to be assembled.

How the SHT 5020 Is Constructed

The Aqua-Scanner consists of two sections with different functions. Only one of them detects water.

1

Sensor Cable, the Sensitive Section

The 2 m long black-and-white sensor cable is the part that detects water. It consists of two sensor wires in a fluoropolymer carrier rod. The sensor cable is metal-free, abrasion-resistant, corrosion-resistant and non-locating.

2

Connection Point

At the transition from the sensor cable to the connection cable, both sections are permanently joined. Protect this point from moisture and from tensile stress.

3

LIYY Connection Cable, for Connection Only

The white two-core LIYY cable is 1 m long and has two conductors (brown and white) of 0.14 mm² each. It connects the Aqua-Scanner to the water alarm and does not detect water itself. Extending this cable does not increase the sensitive sensor path.

How the SHT 5020 Detects Water

The sensor operates passively. Evaluation is performed by the connected water alarm.

🏜️

Cable Dry

There is no conductive connection between the sensor elements. The water alarm evaluates “no water”.

💧

Cable Wetted

Conductive water connects the sensor elements. The water alarm evaluates “water detected” and triggers the set response.

🔇

No Own Alarm

The sensor itself does not generate an acoustic warning signal. Alarm and display come from the water alarm.

📍

Detection Without Location

The Aqua-Scanner reports water but does not determine the exact position of the wetted point.

🚰

Which Water Is Detected?

Sufficiently conductive water must reach the cable. Very pure water may have too low conductivity for reliable detection. Check the function with the actual liquid that occurs.

Lay Out, Connect, Test

Water is detected where it sufficiently wets the sensor cable. Therefore ensure that escaping water can reach the cable.

Laying

  1. Define the monitoring path, for example along a possible leak point, behind fixtures or under a water-carrying system.
  2. Lay the sensor cable so that escaping water can reach it. Choose water paths or places where water collects.
  3. Water between cable sections is only detected once it reaches the cable. Therefore route the cable according to the expected water path.
  4. Do not route the sensor cable in a pinched condition or over sharp edges.
  5. Do not run the connection cable parallel to 230 V mains cables and protect connection points from moisture.

Connection

  1. Identify the water alarm (SHT 5000 or SHT 5001). The connection terminals are described in its operating instructions.
  2. Connect the two-core connection cable exclusively to the designated sensor input.
  3. Carry out extensions and connections suitable for the respective environment and observe the device-specific requirements.
  4. Check the entire alarm chain: water detection, display, acoustic alarm and the intended follow-up function.

Notes on the Cable

  • Use unshielded LIYY cable, max. 2 × 0.14 mm²
  • Factory-fitted 1 m connection cable, extendable up to 50 m total length per sensor circuit
  • Extending the connection cable does not increase the sensitive sensor path
  • Extension of the sensor cable is possible on request directly from the manufacturer
  • Do not run parallel to 230 V
  • Additionally observe the specifications of the connected water alarm

Commissioning

  1. Visually check the routing, cables and connection points.
  2. Deliberately wet the sensor cable at several different points along the sensor path with water. The test must show that water actually reaches the cable.
  3. Observe the response: indication on the water alarm and the intended follow-up function.
  4. Then allow the sensor cable to dry. Check the return to the normal state and, if necessary, the required acknowledgement on the water alarm.

Manufacturer's Notes

  • Read the instructions for the sensor and the instructions for the connected water alarm and keep both
  • Work on mains voltage may only be carried out by qualified electricians; switch off and verify absence of voltage beforehand
  • Never connect low-voltage models to mains voltage
  • Do not connect passive water sensors directly to a supply voltage or an electrical load
  • Connect only to a suitable sensor input of the intended water alarm
  • Use only in normally dry locations
  • Do not continue to use damaged cables or housings
  • Do not open potted components
  • Keep packaging material away from children
  • Always perform a full functional test after installation, connection or modification
  • Repairs and maintenance may only be carried out by the manufacturer or authorised specialist personnel

What the SHT 5020 Does Not Do

  • It detects water only where it sufficiently wets the sensor cable
  • It is not locating and does not indicate at which point on the cable the wetting has occurred
  • It is not a level sensor. For permanent level monitoring the manufacturer recommends a suitable float switch
  • It is not intended for permanently flooded areas or continuous liquid exposure. With prolonged wetting the water indication may remain
  • It has no own alarm; warning and follow-up function are handled by the water alarm
  • Very pure water may have too low conductivity and may not be reliably detected
  • The drying time of approximately 15 seconds is not a guaranteed reset time for every installation situation
  • The connection cable is only conditionally waterproof. Specifications for float switches do not automatically apply to electrode sensors

Clean, Check, Find Faults

Cleaning and Rechecking

  • Carefully clean the sensor cable with a soft, damp cloth
  • Do not use aggressive or solvent-containing agents
  • Remove deposits and then allow the sensor cable to dry
  • Repeat the functional test after cleaning or changing the routing

Frequently Asked Questions

How does the Aqua-Scanner SHT 5020 work?

The sensor cable detects conductive water along its sensitive section. When a sufficiently conductive connection is created between the sensor elements, the connected water alarm responds according to its settings. The sensor itself does not generate an acoustic alarm.

Which part of the cable detects water?

The 2 m long black-and-white sensor cable is the sensitive section. The additional 1 m long white LIYY cable serves exclusively for connection to the water alarm.

Does the sensor cable automatically monitor the entire floor area?

Water is detected where it sufficiently wets the sensor cable. Therefore lay the cable along possible water paths or at places where escaping water collects. Water between cable sections is only detected once it reaches the cable.

Does the SHT 5020 indicate the exact leak location?

No. The sensor cable is not locating. It enables a water indication but does not determine the exact position of the wetted point.

With which water alarms can I use the SHT 5020?

The SHT 5020 is intended as an accessory for the Schabus water alarms SHT 5000 and SHT 5001. Connect it to the designated sensor input and also observe the operating instructions of the respective water alarm.

Can I extend the cable?

Distinguish between the sensitive sensor path and the LIYY connection cable. The connection cable is factory-fitted at 1 m and can be extended with an unshielded LIYY cable (max. 2 × 0.14 mm²) up to a total length of 50 m per sensor circuit. A longer connection cable only extends the connection path and does not detect water itself. Extension of the sensor cable is possible on request directly from the manufacturer. For special lengths and the permissible connection length you need a version matched to the water alarm used; therefore ask the manufacturer before ordering.

For which installation locations is the sensor suitable?

It is suitable for normally dry areas where water can escape over an area, for example under kitchen and bathroom furniture, under aquariums, baths and tanks, along pipelines, in technical rooms, HVAC systems, data centres and accessible inspection shafts.

How quickly is the sensor cable ready for use again after a water indication?

The operating instructions state a drying time of approximately 15 seconds. This is not a guaranteed reset time for every installation situation. After drying, check the return to the normal state. Whether the alarm additionally needs to be acknowledged depends on the connected water alarm and its settings.

Is the sensor cable suitable for permanently wet areas?

No. The SHT 5020 is intended for normally dry installation locations. With prolonged wetting the water indication may remain. For permanent level monitoring use a float switch suitable for that purpose.

Does the sensor detect distilled water or condensation?

Very pure water may have too low conductivity for reliable detection. Therefore check the function with the actual liquid that occurs under the intended operating conditions.

How do I clean and check the sensor cable?

Clean it carefully with a soft, damp cloth. Do not use aggressive or solvent-containing cleaners. Then wet various points along the sensitive sensor path and check the response of the connected water alarm. Afterwards allow it to dry and check the normal state.

What to do if the sensor does not respond or the indication remains?

If there is no response, check whether the model, connection and sensor input are correct and whether the sensor cable is really being wetted. If the indication remains, check residual water, deposits and acknowledgement on the water alarm. In the case of unexpected indications, check damp connections and the cable routing. If the fault persists, put the system into a safe state and contact Schabus Support.

Are there options or additional variants?

No. The SHT 5020 has no options. With the permanently connected connection cable it is complete. Special lengths are available on request from the manufacturer.

How long is the guarantee valid?

The statutory warranty of at least 2 years in the EU applies. In addition, the manufacturer Schabus offers a 5-year guarantee that can be registered online.
