Things to consider before buying a sensor tap

Known issues, tips and things to consider

Autotaps.com's aim is to supply you with the highest quality product that's robust and reliable. But there are still other 'third party' factors that affect the way sensor taps works. These factors are outside the scope of our company's responsibility but they are highlighted below to help you make better decisions when buying sensor automatic products.

High visibility clothing

It's a known fact that infra red sensors can be triggered by high visibility clothing. Prolonged exposure of infra red sensor to high visibility clothing can cause the sensor to malfunction and cause damage. If a sensor tap is needed in an area where the users will be wearing high viz clothing, we recommend that you consider using a sensor tap with hidden sensor eye for example: ATT-1101, ATX-0049, ATW-0048.

 

Shiny/Reflective surfaces

Highly reflective or shiny surfaces of some accessories i.e. sinks can cause the sensor to function incorrectly. This is a common factor especially with sensor taps with downward-facing sensor eyes i.e. ATX-8204, ATW-1204, ATW-0512, ATT-1101. Please make sure your choice of accessories are compatible with an infra red sensor.

 

Gravity-fed water supplies

You need at least 0.7 bar of equal pressure (both hot and cold) for the sensor tap to work efficiently. Users with gravity-fed water supply suffers low water pressure, and a pressure pump or booster may be needed to increase the pressure. You can search the internet or Amazon for pressure pumps/boosters that might be suited to your needs.

Sensor timing and behaviour

The basic working principle of our sensor is that it will only operate when the user approaches the proximity range, and shuts off once the user retracts from the sensor zone. For example, users can expect the sensor to switch off automatically when washing hands because the user might have moved away from the sensor zone. The sensor will automatically come back on with a reaction time of around 1 second or less.

 

If the user is in the sensor zone and motionless, the sensor will only dispense water for approximately 45-75 seconds and it will automatically switch off (for security/flooding reasons). If the user wants more water, the hands/objects needs to leave the sensor zone and re-enters it again.

 

Temperature control

Most of our sensor taps have single supply feed, if you want your sensor tap to regulate hot and cold, you'll need a thermostatic valve (ATV-0076) or a blending valve (ABV-0012). A thermostatic or a blending valve won't be needed if you have a pre-mix water supply feed. Click here to learn more about different ways to control a sensor tap temperature.

 

Sensor obstruction

Do not obstruct the sensor eye or cover the sensor eye with anything even with transparent objects i.e. glass.

 

Sensor distance

Typical sensor distance or proximity zone is between 10-15cm, and around 23cm for ATW-1288.

 

Your choice of accessories

In general, accessories i.e. sinks or basins are made using different types of materials and finishes, and some of these materials can trigger an infra red sensor to act abnormally. Please make sure any accessories you've chosen is compatible with our products. Please note that customer's choice of accessories are outside the scope of our company's liability, and we cannot accept any responsibility for any discrepancies, refunds, faults, malfunctions, cost of installations/removal arising from such situation.
