1. General Information
These instructions should be read carefully and retained for
further reference and maintenance.
Timeguard reserve the right to alter these instructions
at any time. Up to date instructions will always be available
for download at www.timeguard.com
2. Safety
• Before installation or maintenance, ensure the mains supply
to the PIR is switched off and the circuit supply fuses are
removed or the circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or
used for the installation of this PIR and install in accordance
with the current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this
luminaire is fitted does not exceed the rating of the circuit
cable, fuse or circuit breaker.
• To clean use a clean dry cloth only. Do not use liquid cleaners.

4. Selecting a location
• The PIR has a number of detection zones at various
horizontal and vertical angles as shown below.
• A moving human body or object needs to cross one of
these zones to activate the sensor. The optimum height
for this is a 3m mounting height. Careful positioning of
the PIR is required to ensure the best performance from
the PIR and the appointed approach path.
Effective Approach Path
(ACROSS)
Ineffective Approach Path
(TOWARDS)
• Avoid positioning the PIR near any sources of heat in
and around the detection area such as extractor fans,
tumble dryers or boiler exhausts etc. This would also
include other light sources such as security lights.
The detection zones are a representation of the subjects walking path and not
of the detection angle.

4
• Reflective surfaces (i.e. pools of water, white painted
walls, overhanging branches and other types of foliage)
may cause false activation under heightened weather
conditions.
• During extreme weather conditions the PIR may exhibit
unusual behaviour. Once normal weather resumes, the
PIR will carry out normal operations.
• An isolating switch should be installed to enable the
power to be switched ON and OFF for maintenance
purposes.
• Remove the top cover of the sensor by twisting the top
cover anti-clockwise. The top cover can now be removed
from the sensor body.
• Loosen the x2 tapped screws from the mounting plate of
the PIR and the main body.
• Using the mounting pate as a template, mark the position
of the fitting holes.
• Drill the holes and insert the rawl plugs into the fitting
holes.
• Pass the supply cable through the cable entry point on the
foam gasket and then the mounting plate, ensuring the
grommet is used to maintain the IP rating of the PIR
sensor.
5. Installation

5
• Terminate the cable into the terminal block ensuring
correct polarity is observed and that all bare conductors
are sleeved (see section 6 Connection Diagram).
• When wiring is complete, it is recommended that the
ceiling mounting plate is fitted to the sensor body via the
previously loosened x2 screws and fixed to the ceiling.
• Insert fixing screws through the sensor assembly into the
wall plugs and secure. Do not over-tighten, if using a
power screwdriver ensure it is set to a low torque setting
so as not to damage the unit. Set the unit up as follows,
before refitting the decorative cover.
• The adjustment knobs located on
the topside of sensor main body.
They are factory set to
“Walk Test Mode”.
Double check they are
set as follows;
TIME: Fully anti-cloclwise,
LUX: Fully Clockwise,
SENS: Fully clockwise.

• Connect cables to the terminal block as follows;
If the load connected to the PIR is of Class I construction, continue the earth
continuity from the 230V 50hz mains circuit to the load.

7. Setting Up
Walk Test Procedure
• Turn the power to the unit ON. The lamp will immediately
illuminate as the unit goes through its “warm-up” period.
After approximately 1 minute the lamp will extinguish.
This indicates the unit is wired correctly and the unit is in
Test Mode.
• Try to remain outside the detection area during the
warm-up period.
• The unit will now operate during daytime as well as at
night, illuminating the lamp for approx. 2 seconds each
time. This allows testing to be carried out to establish
whether the sensor is covering the required area.
• Walk across the location the sensor is fitted, to establish
the detection area.
• The sensor will detect you approximately up to 12 metres
in diameter at mounting height of 3m.
• As you cross a detection “zone” the lamp will illuminate.
Now stand still until the lamp extinguishes
(this should take approx. 2 seconds).
• Start moving again after 2 seconds. As you cross each
“zone” the lamp will illuminate.
• Repeat the above, walking at various distances and angles
to the unit.This will help you to confirm the detection
pattern.

Setting Up for Automatic Operation
• When walk tests are done, adjust for automatic operation.
• The TIME setting controls how long the unit remains on
following activation and after all motion ceases.
• Use a thin flat blade screwdriver to make adjustments.
• The Time control knob at fully anti-clockwise is Test Mode,
slightly adjust to above the T is minimum time approx.
1 min, whilst the maximum time is approx. 30 minutes
indicated by the 30 position on the dial. Fully clockwise is
dusk till dawn indicated by “D”, meaning the light will
remain on at night and switch off in the morning,
providing that significant natural light is visable by the PIR.
• Set the control to the desired setting between these limits.
• The DUSK (LUX) control determines the level of darkness
required for the unit to start operating. The setting is
best achieved by the procedure below;
1. Set the DUSK control knob fully anti clockwise.
2. When the ambient light level reaches the level of
darkness at which you wish the lamp to become
operative (i.e. at dusk) SLOWLY rotate the control in a
clockwise direction until a point is reached where the
lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at
approximately the same level of darkness each evening.

9
• Observe the operation of the unit. If the unit is starting to
operate too early (i.e. when it is quite bright) adjust the
control slightly anti-clockwise. If the unit starts to operate
too late (i.e. when it is very dark). Adjust the control
slightly clockwise.
• Continue to adjust until the unit operates as desired.
• Once the unit is set up as desired, adjust the sensitivity
level as to your requirements via the sensitivity adjustment
dial. Ensure the levels are enough for adequate detection,
subject to your installation location.

Manual Override Function
• To activate the manual override, turn the connected light
switch OFF then ON within 1.5 seconds. This can only be
done after dusk. The PIR will remain switched on for
up to 6 hours or until dawn if this comes first.
Note: The red LED
indication light
will flash when movement
is detected. Otherwise it
will remain off.
The red LED indication light
will flash every 1 second during
the PIRs warm up period or after
a restart from a loss of power.
While the manual override
is active the LED indication
will remain off until back in
auto mode.
