(ex VAT)Marnic Water Watch - PIR Urinal Flush Controller
![]() Can be calibrated to flush up to 4 times per hour but we recommend it is set to flush 20 minutes after the sensor detects a user, therefore a maximum of 3 times per hour. If no user is detected (e.g. over weekends), there is a choice of flushing after 12 or 24 hours. The solenoid can be installed on either vertical or horizontal pipe. An arrow on the brass body indicates the direction of flow. See the 'More Product Info' tab for a list of other product features

(ex VAT)Cistermiser - IRC Sensor with Ceiling Kit
The IRC has the advantage of being packaged for installation onto a wall, recessed into a false ceiling or directly onto the water supply pipe. The included solenoid valve is plumbed into the water supply to the urinal cistern. The connection to the control sensor box can be made by mounting the box directly onto the solenoid valve or remote from the valve, using the 'floating socket'. Features: The unit is supplied with mains and battery power options, so no additional external transformer is required.
How it works:
When movement is detected a pulse is sent to open the solenoid valve and water flows to the cistern. At the same time, the PIR sensor is switched off. The initial open period is 25 mins after which time PIR power is restored. Any occupancy in the next 5 minutes will cause the cycle to repeat (30min total cycle). If no occupancy, then the solenoid stays closed till the next occupancy is detected. Flow rate to the cistern is adjusted via the flow regulator in the valve. Generally, this should be set so that the cistern fills and flushes once in every 30 minute cycle. If there is no occupancy in 12 hours, the solenoid will automatically open for 30 minutes to provide a hygiene flush to the urinals and pipework. |
