AV Range
The AV Range is an anti-vandal range of washroom
products for use in high risk situations such as sports
centres, prisons, schools etc. It is deck mounted and
has a single water inlet suitable for a premixed or cold
supply.
How easy/difficult is the product to install?
The product is not difficult to install. It uses typical
plumbing fittings and techniques. The electrical
installation is very straight forward especially for the
qualified electrician. An experienced BMS engineer
would only be required, if the control is to be
integrated into a Building Management System.
However this is not a requirement.
What is the minimum and maximum working
pressure?
The minimum working pressure is 0.5bar or 5m head.
The maximum working pressure is 6bar.
How do I configure dual flushing of the WC?
When you program the flush time of the WC,
program the time it takes to deliver just a part flush.
Typically a time setting of 2 to 3 seconds is suitable.
If a user then wants a full flush, they only have to
press the button twice and the valve will deliver the
full volume of water in the cistern. The actual full
flush volume is determined by the height setting of the
float.
What if I don't want dual flushing of the WC?
When you program the flush time of the WC,
program the time it takes to deliver a full flush/empty
the cistern. Typically a time setting of 7 seconds or
greater is suitable. The actual full flush volume is
determined by the height setting of the float. If a user
presses the button twice the volume of water that the
valve flushes is not affected, as this is determined by
the float height.
What flow/flush times are recommended?
Recommended durations depend on the application
and where outlets are being installed but typical
durations are as follows:
- Shower: 30-120 sec
- Basin: 30-60 sec
- Urinal: 5 sec
- WC: 2-3 sec (if dual flushing is used)
- WC: 7-10 sec (if dual flushing is not used)
What is the flow rate through the outlets?
The flow rates are as follows:
- Shower outlets: 7 litres per minute
- Basin outlets: 1.7 litres per minute
- WC outlet: flow rate depends on combined WC suite but WRAS requires a flow rate of 1.2 litres per second. Urinal outlet: pressure dependent typically 4.2 litres per minute
How do you connect the system to a Building
Management System?
Please refer to the installation instructions and we
suggest a BMS engineer should be consulted.
How many products can be controlled by one
control box?
Six
Do the products connected to the control box have
to be the same i.e. all showers, all WCs?
One AV Six Channel Controller can control any
combination of products.
What is the maximum distance that the control box
can be installed away from the outlets?
20 metres maximum
Can the 3m cable be extended on the Piezo touch
button
Yes, an additional 17 metres of cable can be added to
a maximum total cable length of 20 metres.
Is there a no-touch sensor available instead of the
Piezo button?
The AV six channel controller does not yet support
no-touch sensors, however Cistermiser has a full
range of no-touch outlets available.
What diagnostics are provided and where are they
located?
Alarm warnings can be sent to a remote indicator or
BMS when abuse, battery failure or memory failure
has been detected.
Is repair and maintenance straightforward?
Repair and maintenance should be minimal and
manageable for any qualified plumber or electrician.
Is it easy to clean the outlets?
The stainless steel outlets are resistant to chemicals
and can therefore be easily cleaned.
