PIR Sensor Flush Controls for urinal cisterns

We generally recommend a PIR Usage Sensor controller as being the best solution for most washrooms. The Gentworks Flow Saver is the most popular with our online customers and offers outstanding long-term reliability and water saving.

Flow Saver PIR Urinal Flush Controller Kit

Flow Saver PIR Urinal Flush Controller Kit

FSFCV01

Battery Powered PIR Sensor Flow Control kit for urinal cisterns, everything you need in one box.

Maintains hygiene standards whilst conserving water and dramatically cutting water costs – saving up to 95% of water usage compared with an uncontrolled cistern, and around 30-40% against more basic water management systems.
The Flow Saver consists of an electronic control sensor unit and a solenoid for installation into the water supply pipe of a urinal auto cistern. The unit monitors washroom traffic to schedule cistern flushes. Where no motion is detected a hygiene flush is initiated at 12 hour intervals. During high usage periods where the number of detections exceeds 20, the unit will temporally switch from 30 or 60 minute flushing to 15 minute flushing for improved hygiene.

Features:
•    Anti-Vandal Polycarbonate Domed Housing
•    Test Cycle Function
•    Easy Setup with LED Status Indicator and Beeper
•    Battery Powered
•    Low Battery Warning Light
•    Tamper Proof Cover With Key
•    Wall or Ceiling Mounted
•    High Quality WRAS Approved ASCO Latching Solenoid Valve

- Flush controller unit with sensor eye for wall or ceiling mount above the urinals
- Asco solenoid valve for fitting to water supply (15mm compression fit)

Marnic Water Watch - PIR Urinal Flush Controller

Marnic Water Watch - PIR Urinal Flush Controller

WW01-B
A wide-angle PIR sensor manufactured by Marnic Technologies, in an enamel painted steel case. Many thousands of this inexpensive, yet high-quality, controller have been supplied to Gentworks customers. They are very popular with schools and local authority sites as well as pubs, offices and factories. 

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.

Includes:
- Flush controller box with sensor eye for wall or ceiling mount above the urinals
- Marnic Solenoid valve for fitting to water supply (15mm compression fit)
- Approx 1m of 2 core cable to connect controller to solenoid
- 4.5v Alkaline Duracell battery with tails (Battery version only)
- 240v to 4.5v Built in Power Supply (PSU) (Mains version only)

See the 'More Product Info' tab for a list of other product features

Cistermiser - IRC Sensor with Ceiling Kit

Cistermiser - IRC Sensor with Ceiling Kit

402EIRC
 
 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:
- reduced water consumption by up to 80%
- reliable and low maintenance
- passive infra-red sensor, occupancy detection
- single valve output
- adjustable flow rate
- janitorial flush (if sensor not triggered for 12 hours)
- WRAS approved Product 

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.
