1. Introduction
The infrared urinal flush control (IRC) valve automatically manages the
supply of water to a urinal cistern.
The IRC is only to be used in conjunction with a cistern and is suitable for
fixing to solid or cavity walls and false ceilings, or directly onto pipework.
The IRC sensor unit can be installed separately from the solenoid valve.
On detection of movement in the washroom, the IRC activates a 30 minute
cycle allowing water to flow into the cistern.
During the last five minutes of the 30 minute cycle the sensor ‘looks’ for
movement. If no movement is detected during these five minutes the
valve will close. If the sensor detects movement a new 30 minute cycle is
activated. If no movement is detected for 12 hours the IRC will activate a
hygiene cycle.
