Product Description

• 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 onto the solenoid or by using the ‘floating socket’ supplied for a remote mounting. If mounted remotely, the sensor module may be:
  • Surface mounted using a standard pattress box.
  • Recessed into a suspended ceiling using the ‘flush mounting kit’ (FMK), supplied with the IRC as standard.
• The installer or user can adjust the time the valve remains open and therefore how long the cistern takes to fill and how much water is used. When the washroom is not being used the water supply pressure remains constant and the valve remains closed preventing water passing into the cistern.
• 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 pipe work.
• 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 solenoid is supplied with an interchangeable valve seat which is used to increase the flow to the cistern on low pressure supplies.
