Occupancy
Sensor Unit
Do
you operate a commercial business and are sick of your high water
bills? With our Occupancy Sensor Units fitted to your washroom urinals
you can
drastically slash your water bills.
 |
The
O.S.U. is a Water Bylaws Scheme
Approved System, which meets Health
and Safety requirements and helps slash water bills.
As a water management system the Occupancy Sensor
Unit helps you comply with legislation and make major savings at the
same time!
Unlike hydraulically operated units, the O.S.U is designed to flush
within a short time of every use, typically no more than 30 minutes, so
the urinal stays fresher for longer. |
Some of the benefits and key features
- Typical payback
within six months
- Optimum water
usage
- Proven
reliability
- Programmable
maintenance flush
Fast filling ensures that the cistern gives a proper flush, avoiding
the constant trickle out which sometimes happens with trickle-fed
cisterns. Cycle time may be adjusted at any time to 20, 30, 40 or 60
minutes.
How
The O.S.U. Works
The
O.S.U. waits until movement is detected, then delays before filing and
flushing the cistern.
Cycle
time, from triggering to the end of the flush, may be set to 20,
30, 40 or 60 minutes.
Fill time, up to 31 minutes, is easy to set. In standby, a maintenance
flush happens every 8, 12 or 24 hours, timed from last flush.
The
PIR can be located anywhere to give optimum detection - on the
ceiling or wall
