EMatic_PMFMC_Instructions_Rev01
The PMFMC is a High Frequency (5.8GHz) 360˚ occupancy detector. High frequency signals are
able to penetrate non-metallic materials such as wood, brick wall, glass, etc., but can not
penetrate water or metal. High frequency sensors are less affected by temperature, airflow, wind,
but humidity and vibration can often affect the performance of high frequency sensor. The sensor
is more sensitive for movement at different speeds and it is less sensitive for movement at the
same speed, therefore, the detection range could be reduced.
Due to high frequency signals can penetrate non-metallic materials, this may lead to false
activations, i.e. water movement in plastic pipes, movement outside the area, or if there is a lot of
metal in the detection are that may reflect the high frequency signals, therefore, the location of the
sensor is very important.
NOTE:
The high-frequency output of the sensor is <0.2Mw,
that is just one 5000th of the transmission power of a mobile
phone or the output of a microwave oven.
IMPORTANT NOTE:
Installation must be performed by a skilled electrician who is familiar with the appropriate standards and
technical requirements of the appliance and its proper installation.
The person carrying out the installation is to check and verify that the total load including in-rush current
on the circuit, the rating of the cable, fuse and/or circuit breaker is not exceeded.
INSTALLATION
•
Ensure the mains supply is isolated
•
Ensure the sensor will be flushed in to a ceiling free from movement or vibration at a mounting
height between 1.8 - 3.5m
•
Cut a circular hole in the ceiling ensuring no pipes or cables are behind
•
Remove the terminal cover and make the necessary connections, please refer to the below wiring
diagram for termination connections then re-fit the terminal cover
•
Partially Insert the sensor in to the ceiling so the adjusters for the TIME, SENS and LUX can be
altered, please refer to below test section
•
After testing and final adjustment of the TIME & LUX settings to the desired level, fully insert the
sensor in to the ceiling ensuring it is secure
