4. Installation Advice
As the PIR sensor responds to changes in temperature,
avoid the following situations:
• Mounting the sensor near objects with highly reflective surfaces,
such as mirrors etc.
• Mounting the sensor near heat sources, such as heating vents,
air conditioning units, lights etc.
• Mounting the sensor near objects that may move in the wind,
such as curtains, tall plants etc.
5. Installation
5.1 Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.

5.2 An isolating switch should be installed to enable the power to be switched
ON and OFF for maintenance purposes.
5.3 Mark the position of the 45mm diameter locating hole centre, taking care
to avoid ceiling joists and other obstructions within the 45mm diameter.
5.4 Use a pad saw or suitable hole-cutter to cut out a 45mm diameter hole.
5.5 Pass the 230V 50Hz mains supply and load cables through the hole
and prepare for termination.
5.6 Loosen the spring loaded fixing screws on the bottom of the PIR,
which will release the hinged clear plastic terminal cover.
Note: the fixing screws do not need to be removed.
5.7 Terminate the cables into the terminal block ensuring correct polarity
is observed and that all bare conductors are sleeved
(See section 6. Connection Diagram).
5.8 Close the hinged clear plastic terminal cover and tighten the spring loaded
fixing screws to secure into place.
5.9 Remove the shroud cover located on the top of the PIR, by turning
it anticlockwise by a half turn. This will reveal the adjustment knobs.
5.10 Make sure the adjustment knobs located beneath the sensor head
are set to ‘Test Mode’;
TIME – Fully clockwise to the ‘T’ symbol (Test mode).
LUX – Turned clockwise to the ‘Sun’ symbol.
5.11 Push back the locating springs and feed the unit into the ceiling
void via the 45mm hole. The locating springs will now fold back
and hold the PDFM360MINI sensor in place.
