Specs

Product Information

The Infrared Control Valve IRC® automatically manages the supply of water to a urinal cistern. The unit employs motion-sensing infrared to control valve operation and reduce water consumption by over 80%. The PIR sensor detects movement and activates the solenoid valve, allowing water into a urinal cistern.

And now the best is even better. Incorporating the same proven and robust brass valve, new features include a stylish and compact body shape, an economy mode option to provide even greater water savings and a design which allows easy-to-use battery replacement.

The solenoid assembly is plumbed in on the water supply to the urinal cistern. The connection to the infrared sensor is made either by directly mounting the sensor module on to the solenoid or by using the ‘floating socket’ supplied for a remote mounting.  If mounted remotely, the sensor module may be:

  • Surface mounted.
  • Recessed into a suspended ceiling using the cutting template and mounting bracket, supplied with the IRC® as standard.

If the sensor detects no occupancy in 12 hours it will automatically open the valve for 30 minutes to allow one flush of the cistern to rinse the urinals and pipework.

The sequence is designed to maximise battery life, giving approximately 3 years’ life from one good quality set of batteries.

The flow rate of the water into the cistern is adjustable to maximise water economy. Generally this should be set so that the cistern flushes once every time the valve is opened i.e. every 30 minutes during occupation.

The IRC® urinal flush control consists of a solenoid valve and the infrared sensor module.

When the IRC® detects movement in the washroom, a pulse from the sensor opens the normally-closed solenoid valve and water flows to the cistern. The LED flashes to show the valve is open.

In Normal mode, the IRC® operates with a 30-minute cycle. This means that the cistern will flush a maximum of 2 times per hour.

In Economy mode, an additional delay of 15 minutes is provided before the Normal mode operating cycle is activated, to save even more water. This means that the cistern will flush a maximum of 2 times in 90 minutes.

Product FAQs

We’re here to Help!

Q
The installation is complete but the Test Mode does not work. What can I do?
A

Things to check:

  • Is there power? 

Solution: Ensure the unit is powered. Change the batteries if battery powered; ensure mains electrical power is functioning if mains powered.

  • Is there a fault with the power supply?

Solution: Disconnect one source of power and check by pushing the test button. When the sensor is mounted directly on the valve it should be battery powered ONLY. Also check the remote wiring if the sensor is remote from valve.

Q
The installation is complete but there doesn’t appear to be any water passing the valve. How can I correct this?
A

Things to check:

  • Water supply.

Solution: Ensure the water supply is turned on and is reaching the valve. The valve is suitable for water pressures of 0.1 to 6 bar.

 

  • Is there a blockage on the outlet pipe?

Solution: If a petcock or bibtap has been fitted, make sure it is removed or fully open. Our installation instructions state that there should be no restriction after the valve.

 

  • Is the mesh filter blocked on the inlet?

Solution: Remove the valve so you can check that the filter on the inlet side of the valve is completely clear.

 

  • Is the flow regulator open?

Solution: Make sure the flow regulator is completely opened and when the valve is letting water run, turn down to the required flow rate.

 

  • Is the water pressure high (above 6 bar)?

Solution: Fit a pressure reducing valve before the IRC valve.

 

  • Is the power working?

Solution: Check that the unit is powered. Change the batteries if it is battery powered. If mains powered, ensure that the mains electrical power is functioning.

 

  • Has economy mode been activated?

Solution: The unit may have been put into economy mode. See Section 7 of the Installation Guide to reverse this (available to view in the Downloads area of this website).

Q
The installation is finished but water is continuously flowing through the valve. What should I do?
A

Things to check:

  • Activation process 

Solution: Once activated the valve will remain open for a period of 30 minutes and will reactivate if someone comes within the range of the sensor in the last five minutes of the 30 minute period.   So the valve will appear to work continuously as long as someone is in the washroom.

  • Is the power working? 

Solution: The power may have failed while the valve is in the ‘open’ position. Check the unit is powered. Change the batteries if it is battery powered. If mains powered, check that the mains electrical power is functioning. Go through a test cycle when power is restored.

  • Valve may not be fitted correctly.

Solution: Check the valve and ensure that the arrow on the brass body is pointing in the direction of water flow.

Q
It looks like the valve is remaining shut when the room is occupied but open at other times. What should I do?
A

Things to check:

  • Remote wiring may be incorrect

Solution: If the valve and sensor have been set up remotely, ensure the remote wiring is wired as follows: ‘1’ to ‘1’ and ‘2’ to ‘2’. If you find the wiring is connected ‘1’ to ‘2’ and ‘2’ to ‘1’ then the valve is working in reverse.

Q
I think the water flow rate through the valve seems to be very slow. How can I increase the flow?
A

Things to check:

  • Flow Regulation

Solution: Increase the flow rate by turning the flow regulator anti-clockwise until you reach your desired flow rate; ideally it should fill the cistern once per activation and then flush. See Step 6 ‘Commissioning’ in the Installation Guide (available to view in the Downloads area of this website).

 

  • The mesh filter may be blocked

Solution: Check to ensure that the filter on the inlet side of the valve is clear.

Q
I think the water flow rate through the valve seems to be very fast and the cistern is flushing too frequently. How can I decrease the flow?
A

Things to check:

  • Flow Regulation

Solution: Decrease the flow rate by turning the flow regulator clockwise until you reach your desired flow rate. Ideally it should fill the cistern once per activation (i.e. every 30 minutes) and then flush. See Step 6 ‘Commissioning’ in the Installation Guide (available to view in the Downloads area of this website).

Q
I have just changed the batteries and there is no power to the unit. What should I do?
A

Things to check:

  • Battery orientation

Solution: Check the battery orientation. Ensure there is no excessive corrosion on the battery terminals. Use batteries that are a reputable brand.
