This Infra-red valve is made by Cistermiser. The solenoid assembly is plumbed in on the water supply to the urinal cistern and connection to the control sensor box can be either mounted directly on the solenoid or remotely mounted using the 'floating socket'. It is simple to install and calibrate. The unit has mains or battery power options in the same box, so no additional external transformer is required.
Kit comprises:
Brass solenoid assembly for connection to water supply.
Sensor module which can be mounted directly to the solenoid or remotely on the wall or ceiling requiring a wire connection. For remote mounting the sensor module can be surface mounted using a standard patress box (not included) or recessed into a suspended ceiling using the 'flush mounting kit' which is included.
POWER:
Mains or Battery power options available. If using batteries, 4x1.5 Alkaline type LR6 cells (not supplied) are required. Battery life of up to 3 years depending on battery quality and washroom use / operating frequency.
Features:
- reduced water consumption by up to 80%
- reliable and low maintenance
- passive infra-red sensor, occupancy detection
- single valve output
- adjustable flow rate (see 'operating sequence' below)
- janitorial flush (if sensor not triggered for 12 hours)
- WRAS approved Product
Operating Sequence:
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.
