The Ceiling Mount PIR comes with surface and flush mounted options. It also
has interchangeable white and chrome fascias.
Usage
The PIR sensor has been designed to switch lighting, heating and ventilation loads up
to 10A. The unit is switched on by the detection of moving infra red heat within
a specified range. When infra red heat, such as a moving body, is no longer detected,
the unit will switch off the load after the adjustable time period has elapsed.
If infra red heat is detected again during the timing period, the timing sequence will
restart. The unit has a lux level adjustment and Auto Lux function, which measures
the ambient light levels and prevents lighting being switched on, when there is sufficient lighting in the room. There is sensitivity adjustment
and test mode function added for your convenience.
A POWER FACTOR CORRECTION CAPACITOR OF 4 MICROFARADS WILL OFTEN BE REQUIRED WHEN SWITCHING LOW WATTAGE LOADS, e.g.
LED LOADS. THE CAPACITOR IS FITTED ACROSS SWITCH LIVE AND NEUTRAL SUPPLIES OF SUITABLE ELKAY CAPACITORS CAN BE FOUND AT YOUR
STOCKIST (REF PFCC-1). DO NOT INSULATION RESISTANCE TEST THIS PRODUCT. REMOVE BEFORE TESTING OR TEST CIRCUIT PRIOR TO FITTING.
Positioning
CAREFUL POSITIONING IS ESSENTIAL TO OBTAIN
OPTIMUM PERFORMANCE.
Use the detection range to determine a suitable location for
the sensor. When locating the position of the units, ensure
the sensor is not subjected to bright or direct sunlight or in
areas with high reflective surfaces. Do not site units on a
vibrating surface, or near forced air heating and ventilation.
They should not be placed within 1 metre of the load.
Sensors work when objects move across their field of view.
Position the sensor where people will be detected
walking across the zones rather than towards the zones
identified in Diagram 1. Adjust sensitivity to suit the area that
the sensor has been installed in.
IMPORTANT NOTICE
All wiring should be carried out by a competent person or a qualified electrician and should be fitted to IEE 17th Edition Wiring regulations BS7671:2008.
The circuit should be isolated before carrying out any work. Failure to adhere to the instructions will invalidate the warranty.

troubleshooting guide
Before calling Elkay Technical
we recommend that you attempt to resolve the issue for yourself with this handy troubleshooting guide.
Issue
Problem and Resolution
Load will not switch OFF
• Check terminal connections.
• Check time settings (See Diagram 4).
• PIR is too close to load - Re-position away from lighting, heating and forced air ventilation.
• PIR is switching low wattage or LED loads - Fit Capacitor as stated in instructions PFCC-1.
• Windy weather conditions - Adjust Sensitivity down.
• PIR is re triggered - Check area is left unoccupied for longer that time setting using an
accurate time piece.
• Sensitivity set too high - Gradual incremental adjustments towards the low setting to
resolve the issue.
Load will not switch ON
• Check terminal connections.
• Lux set too low - Turn off Auto Lux and turn UP lux level to the PLUS (+) setting and wait
for sensor to adjust.
• Sensitivity set too low- Gradual incremental increases towards the High setting to
resolve the issue.
Load switches OFF and
• Check terminal connections.
then immediately comes
• PIR is detecting normally- Find source that is triggering PIR.
back ON
• PIR is seeing infra red heat from the load- Re-position away from heat source
(See Positioning).
• PIR is switching low wattage or LED loads- Fit Capacitor PFCC-1 across switch live and
neutral of load.
• PIR is switching a contactor and the contactor chatters or stays ON - Fit a PFCC-1
capacitor across the switch live and neutral of the contactor coil.
THIS IS AN ALL MASTER SYSTEM.
DO NOT USE SLAVES WITH THIS PRODUCT. THESE PIR’s CAN ONLY BE WIRED WITH EACH OTHER.
PLEASE BE AWARE OF THE CHANGES TO THE TERMINALS FROM PREVIOUS ELKAY CEILING MOUNT TIMERS.
