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.
Full instructions for setting up the sensor are supplied with the frc/set remote control.

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
setup or change occupancy time-out settings.

Increasing Occupancy Coverage -

Occupancy coverage can be increased by adding up to a maximum of five slave sensor
heads ( ) to your existing sensor head.

fnh/slave The fnh/slave comes complete with a

'Y' adaptor to facilitate connection.
A connecting lead may also be required, part number fslXX (XX = length /5m).

units or a 7-pole single socket outlet to provide
control of the connected mains rated luminaires.
Control is ON/OFF and is dependent on a
combination of occupancy detection with an
initiating / overriding wall switch (operating at
ELV).

Controller

Note: The fns1200/U universal sensor can be

setup as occupancy or absence sensing.

The kit comprises a controller, a sensor head, a
sensor link lead and a switch drop lead.

Occupancy sensor

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.

Operation:

Switch control:
Absence detection: When occupancy is no longer

detected, lights will switch OFF after a pre-selected time­out period (default 20 minutes).

Pulse - toggles the lights ON or OFF.

Note:

Multiple switches can be connected in
parallel. 'Y' connectors are available to
enable two switch drop leads to be
connected into one point.
(Part No. fsy/A - adaptor).

Note: By default, absence sensors do not switch lights on due to occupancy, however with an frc/set
setup remote control it is possible to reconfigure the unit to initiate the lights ON with first occupancy ­This is not true occupancy detection as it can only occur where occupancy has timed out e.g. first thing
in the morning.

Operation:

Occupancy detection: Provided the wall switch is in the

occupancy detected by the sensor head. When occupancy
is no longer detected, lights will switch OFF after a pre­selected time-out period.
