NuAire 230PIR User manual
Please note there are high voltages which exist inside
the unit and under no circumstances should it be
opened, there are no user serviceable parts inside.
Introduction
The Passive Infra Red (P.I.R) movement detector works by
detecting the warmth of moving bodies walking through the
area.
When the P.I.R is triggered it will signal the fan or light to run.
The "timer" will run on for the time set. The focusing of the unit
is in fact made up of a number of smaller lenses known as
facets or zones, each zone is focused on a different spot to
give a wide area of coverage.
The P.I.R. is triggered when walking from one zone to the next.
Therefore for optimum detection sensitivity it will operate best
when walking across the zone patterns.
Coding description:
230PIR 10 amp (max load) P.I.R c/w with adjustable timer
230PIR-NT 10 amp (max load) P.I.R with no timer included
The PIR-NT version is normally used in conjunction with fans
which incorporate run on timers. If connecting to a fan without
its own run on timer the Timer version (PIR) should be used.
When using either version for lighting and fan control, whilst
this is suitable for several fans, only one light fitting should be
connected directly to the P.I.R.
Installation
The P.I.R. must be installed in accordance with the latest IEE
recommendations.
Before installing the unit or making any adjustments the
electricity must be switched off.
Positioning the P.I.R. unit
For best results never position over a heat source.
Never position in a draught.
Do not place in direct sunlight.
Take account of exit/entry points.
Always seal PIR cable entry.
Fix securely to wall or ceiling.
Avoid obstructions such as screen/ furniture.
Be conservative on range and angle.
Avoid walking towards the PIR for prime detection.
Avoid long ranges for instant triggering.
Before installing the switch, the best position must be sought
bearing in mind that the unit has a range of up to 6 metres and
will provide
900coverage in all directions. It also should be noted that the
units are not suitable for use in shower cubicles, and should
always be used in an indoor environment.
To avoid unnecessary triggering the P.I.R should not be mounted
in a draught or directly over a heat source such as a radiator.
Caution* - overloading the unit will result in permanent damage,
therefore it should not be used on loads over those stated on
the P.I.R. After installing the fan the P.I.R should be wired to the
switch/timer.
When the installation is complete, if using the Timer version,
adjust the timer by piercing the label in the centre of the timer
adjustment hole on the back of the unit to provide a suitable
run on time for the fan. This is accomplished by using a screw-
driver which is small enough to enter the hole provided. If the
Trigger version is used the run on timer may have to be set
inside the fan.

When the installation is complete, switch on the mains and wait
for the P.I.R to settle down. This could take up to 2 minutes for
the Trigger version and up to 30 minutes for the Timer version
depending on how the timer adjustment is set. To check that
the P.I.R will settle down and switch off the fan, the P.I.R can be
temporarily "blinded" with a piece of paper in front of the lens
to stop the circuit triggering each time.
Each time the circuit is triggered on the timer version it will
extend the fan run on period, i.e the full time delay will
commence each time it is triggered.
