fnh200 Occupancy sensor head
Setting Up
Working in conjunction with fnc type
eZeBox
controllers, the fnh200 sensor head
provides additional sensory data from
the room. This takes the form of
occupancy, and received instructions
from a remote control such as the
Switch
drop lead
frc/user remote control.

The sensor head fits into a 32mm diameter hole, with clips which can grip ceiling panels down to 1.5mm
thick
. The sensor head has a rectangular occupancy detection range broadly 7.4m x 5.6m at a ceiling
height of 2.5m (Longest length of detection aligning with the spring clips). As the ceiling height increases
so will the overall detection area but sensitivity to small movements will decrease.
Note: Make sure that the sensor is not adjacent to circulating air, heaters or lamps.

Setup Remote Control - frc/set
The sensor comes factory set with default operational parameters including a standard
20 minutes occupancy time-out. If another time-out period (2, 5, 10, 20 and 40 minutes)
or alternative operational parameters are desired, then an frc/set remote control will
be required - ordered separately.
Optional Extras
User Remote Control - frc/user
The frc/user remote control is a convenient method for the user to control the lighting
remotely. Lights can be temporarily overridden ON or OFF and in cases where the
lighting control is dimmable, dimmed UP or DOWN. In addition, up to six preset light
levels can be stored and recalled.
Note: Unlike the frc/set remote control the frc/user remote control can not be used to
Increasing Occupancy Coverage -
Occupancy coverage can be increased by adding up to a maximum of five slave
sensor heads ( ) to your existing sensor head.

indicate the projections of the 16 lenses with a single focal point. Movement of an object with higher than
background temperature, between the detection zones, will be detected.
