Shabus 400748 SHT 5001 water detector

The SHT 5001 is a water detector for fixed installation in a small distribution or fuse box. It has 2 reporting lines that are on each one of its own alarm relays and each has 2 inputs for passive water sensors (AC) or minimum swimming switch (DC). In the case of an alarm, the red sensor LED is lit (input 1) or flashes (input 2), an internal piezo buzzer is sounded (permanently deactivated), the assigned relay is switched on and an alarm output (12V / max. 30 mA) is activated to connect an external piezo driver or an LED (e.g. for switch cabinet door). An alarm memory can be set individually for each reporting line by means of wire bridges. The receipt of the alarm is done internally by pressing the key on the RESETkey or externally with the closing of a potential-free contact (e.g. external button, mini-swimming switch, reset contact from the GSM dial, etc.). The TEST key checks the alarm settings, simulates water on both reporting lines. The connected sensors and mini-swimming switches are not tested. The SHT 5001 is operated with power supply from the public electricity grid and / or 12 / 24 V DC voltage from ext. Batteries / accumulators. The warning device must not be operated at the following locations: • directly via a stove or combustion site or via a sink / drain • directly next to or in the air flow of ventilation, fans, air conditioning systems • in areas where dust, moisture or dirt can be disconnected to water detectors • in potentially explosive areas • Hold You the SHT 5001 completely away from wet! Water sensor or mini-swimming switch? What do I need? This question is quite easy to answer: If it is only possible to use a minimum swimming switch from the purpose of use, you must use it. Because then you're dealing with a water level, a level or a stroke. Sensors will work for some time, but with their blanking contacts, they are completely inappropriate for constantly moist environments. Remember that water sensors are wear parts. The more often and longer the water is exposed, the faster they age and at best tend to increase false alarms. Even if you are convinced that your sensor is really dry, water may have penetrated into the inside of the sensor and have caused significant corrosion, rust, green span, etc. there. Sensors are only suitable for regular dry environments, for the detection of water in general on floors and in particular under washing and dishwashing machines, perhaps under the boiler or other water guide equipment, pipes, radiators, etc., the main dry surfaces on which normally or hopefully never come to water. 100 - 240 V / 50-60 Hzpower consumption: approx. 2 - 3 W / VA, depending on the operating state protection: IP 20 for dry indoor information lines: 2 sensors (AC) and / or 2 mini-swimming switch (DC) AC measurement voltage: 115 Hz / 2.5 VppDC measurement voltage: 12 volt line length: AC to 100 m / DC to 300 m (max. 10nF) alarm threshold: AC < 80 k? / DC < 180 k? alarm output: 12 volt / max. 30 mAFunctional range: + 5 degrees C... + 45 degrees C storage temperature: -20 degrees C... + 70 degrees C humidity (environment): 5 - 90% rH (non-condensing) dimensions (HxBxT): 90 x 72 x 57 mm (4 TE hat rail)
