Cistermiser Infra Red Urianl and Cistern Flush Valve
The Infrared Urinal Flush Control (IRC) valve automatically manages the supply of water to a urinal cistern. The PIR sensor detects movement and activates the solenoid valve, allowing water into a urinal cistern.
The Infrared Urinal Flush Control (IRC) consists of a solenoid valve and the 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; at the same time the sensor is switched off. After 25 minutes the power is restored to the sensor and, as long as no movement is detected for 5 minutes, the solenoid valve closes, shutting off the water supply to the cistern.
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:
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 solenoid is supplied with an interchangeable valve seat which is used to increase the flow to the cistern on low pressure supplies.
The IRC sensor unit is contained within a white moulded ABS case designed to fit directly on to the solenoid valve assembly or a standard 3.25” x 3.25” (83mm x 83mm) pattress box for surface mounting.
At the back there is access to the battery compartment or terminals for a 230V mains power supply to the integral and in-built transformer and the 6V DC output to the solenoid
