IRC valves automatically manage the supply of water to a urinal cistern. They consist of two primary elements: a solenoid valve with compression fittings and the sensor module. 

The solenoid assembly is plumbed in on the water supply to the urinal cistern. The connection to the sensor is made either by directly mounting the passive infrared (PIR) sensor module onto the solenoid or using the floating socket supplied for a remote mounting.

The sensor module can be mounted on the unit itself or remotely on the wall or ceiling. If mounted remotely, the sensor module may be:

  • surface-mounted using a standard pattress box, or
  • recessed into a suspended ceiling using the ‘ceiling mounting kit’ (CMK), supplied with the IRC as standard.

A warning light on the front of the sensor module indicates low power if the unit is fitted with batteries and a manual push-button provides a self-test sequence.

Features and benefits

  • Reduces water consumption by up to 80%.
  • Reduces washroom odours.
  • Solenoid valve activated with PIR sensor.
  • Hygiene flush for periods of non-use.
  • Ensures compliance with Water Regulations.
  • Can be concealed to reduce the risk of vandalism.
  • Mains or battery powered option - no external transformer required.
  • Pipe, wall or ceiling mounted sensor: exposed, or flush with ceiling or wall.
  • On DEFRAs Water Technology List; cost is tax-deductible.

Specification wording

The mechanical contractor shall supply and install a urinal flushing device of the ‘Cistermiser IRC’ type on the supply pipe to the urinal cistern, as shown on the drawing.

The flushing control device shall consist of a PIR sensor with a control unit and a solenoid valve with integral flow regulator and interchangeable valve seat.

The flushing control device should have a hygiene flush function for periods of low use.

The flushing control device shall be suitable for supply system pressures of between 0.1 and 6.0 bar.

The flushing control device shall be suitable for connection to either 230V, 50 Hz single phase supply with battery back-up, or powered by 4 x 1.5v alkaline batteries of type LR6.

The flushing control device shall have provision to be mounted directly on the pipework or remotely using either the flush mounting kit supplied or a standard electrical pattress box.

The above flushing device shall be as manufactured by: Cistermiser Limited, Unit 1, Woodley Park Estate, 59 – 69 Reading Road, Woodley, Reading, RG5 3AN Tel: 0118 969 1611
