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
PIR 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.

If a 2 channel surface PIR is required, model number PDSMSB
(Surface Mount Box), along with PDFM362AB
(2 Channel Flush Mount PIR) can be combined to work as a
2 channel surface mount PIR. The flush and surface base plates
are interchangable. PDSMSB (Sold Separately)
Note: Absence mode can only be triggered via using the IR10AB
remote control. (Sold Separately). A push switch is required for
absence mode to work on the PIR.

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
between 2m - 2.5m mouting height. Careful positioning of
the luminaire 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.
•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.

4
•During extreme weather conditions the PIR may exhibit
unusual behaviour if placed in sight of a window. Once
normal weather resumes, the PIR will carryout normal
operations.
5. Installation
• Ensure the mains supply is switched off and the circuit
supply fuses are removed or the circuit breaker turned off.
•An isolating switch should be installed to enable the power
to be switched ON and OFF to the PIR. This allows the
unit to be easily switched OFF for maintenance purposes.
•Mark the position of the fitting
holes using the base of the PIR
as a template, taking care to
avoid ceiling joists and other
obstructions within the
installtion area.
Take note of the hole centres
of the base plate for reference.

Non-dropping
screws
•Knock out the most appropriate
cable entry points on the base
plate for the installation required.
•Pass the 230V 50Hz mains supply and load cables through
the hole and prepare for termination.
•Drill the holes and insert the rawl plugs into position.
•Secure the base plate to the ceiling using the screws
provided.

• Locate the terminal connections and terminate the
cables into the terminal block ensuring that the correct
polarity is observed and that all bare conductors are sleeved.
(See Section 6. Connection Diagram)
•When wiring is complete, tighten the non-dropping screws
shown in the above illustration to secure the PIR to the base
plate and ensure not to over tighten.

7.Commisioning and Operation
• Restore the power from the mains supply breaker or
isolating switch and test for the correct operation.
• Adjust the time dial (fully anti-clockwise), and the Lux
dial should be set to the sun symbol for daylight/night
operation for the purpose of the walk test.
• Allow the PIR to settle down if the attched load is switched
on, this is called warm up mode and can take several minutes
to switch off as long as there is nothing detected in the pickup
area.
• Once the unit is in the OFF position walk across the
detection area, when the PIR is triggered and the load will
turn ON for the minimum set amount of time.
• Once you are happy with the pickup area of the PIR you
can set the Lux dial in the anticlockwise direction to trigger
when dusk is approaching. (This may be best performed in
real time in the evening subject to the users preference).
• You can also adjust the time dial which will vary the
timeout peroids of the PIR once the pickup area is vacated
of any movement.
Walk Test Procedure
8.Switching from Presence to
to Absence mode
• The PIR will come pre-set to presence mode as standard, if
you require an absence detector continue following this
section. Note that a IR10AB remote will be required to
change modes. Otherwise you can skip to section 9.

8
• To switch the PIR from presence to absence mode, press the
lock/unlock button and you will see 2 flashes from the LED
receiver of the PIR, this indicates that the PIR is unlocked and
ready to receive further instructions from the remote control.
Next press the Semi Auto button on the IR10AB remote
control. The LED receiver light will flash once for up to 2
seconds and disappear, this indicates that the PIR is now in
Semi Auto (absence mode).
• When the PIR set to absence mode, the unit will not switch
on automatically when someone walks in the detection area.
• The person in the room must press the retractable push
button for the light to switch on. From this point onwards as
long as detection in the area has constant movement, the
PIR will continue to keep the luminaire or attached load
swtiched on, until the subject has moved out of the detection
area and the time delay function takes over.
• For example if set to 10 minutes the PIR will begin to
countdown from this value once nothing is in the detection
area. If a subject is detected the time delay will reset.
Switching From Presence To Absence Mode:
Switching From Absence To Presence Mode:
• To switch the PIR from absence to presence mode, press the
lock/unlock button and you will see 2 flashes from the LED
receiver of the PIR. Next press the Auto button on the
IR10AB remote control. The LED receiver light will flash
twice and disappear, this indicates that the PIR is now in
Auto (presence mode). There will be up to a 1 minute delay
in changing modes where the PIR will not switch.

Problem Cause/Solution
The luminaire does

in the detection area.
Bulb faulty or missing.
Nearby light sources causing interference.
Redirect the PIR or light source if possible.
