LENS OPTIONS
Several lenses are available for use with the FSP-311. Lenses give coverage at mounting heights between 8' – 40' for applications such
as offices, warehouses, and outdoor use. Density and range of the coverage is determined by the type of lens and mounting height.
A lens with shroud option is also available. The shroud blocks light coming from the fixture, to prevent interference with the photocell
function of the sensor. Lens modules are IP-66 rated when combined with an FSP-311 sensor mounted to an outdoor-rated fixture. See
the FSP-Lx Lens Coverage Guide for more information.
INSTALLATION
1. Determine an appropriate mounting location inside the light
fixture minimizing the electric light contribution to the sensor’s
photocell. Allow a minimum distance of 0.2" (5.1mm) from the
wiring end of the sensor to the wall of the fixture.
2. Drill a hole 1.30" (33.0mm) in diameter through the sheet
metal in the bottom of the fixture.
3. Add the rubber gasket to the threaded collar, and install the
sensor face down, parallel to the mounting surface. Ensure
the rubber gasket touches the inside surface of the fixture.
Install the nut (or optional collar) securely against the fixture
to a torque of 25–30 in-lbs to ensure Ithe lens is installed
properly.
4. Align the locking features between the sensor and lens
module and push the lens module forward until the o-ring
seals firmly. Turn the lens module clockwise to ensure it locks
in place.
5. Connect wires as shown in wiring diagram.
6. Restore power from the circuit breaker.
NOTE:
An optional collar can be installed in place of the tightening
nut. See the Ordering Information table on page 4 for details.
NOTE:
The Outside Fixture Wall thickness should be no
greater than 0.125" (3.18mm) for optimal sensor
mounting and security.

FSP-311 CONFIGURATION WITH THE
SENSOR CONFIG APP
The Sensor Configuration App
is available for both iOS® and
Android® devices. Search
“Wattstopper Sensor Config” on
your device to download.
NOTE:
Bluetooth communication ranges can vary
depending on the device, as well as mobile
carrier. Wattstopper recommends devices with
Bluetooth 5.0. Iphone 8 and Samsung Galaxy
S8 and later devices are recommended for
optimal performance.
The Sensor Configuration
tool is a mobile app for
changing defaults and
testing of the FSP-311.
It provides wireless
access to the FSP-311
sensors for parameter
changes and testing.
Within a certain mounting
height of the sensor, the
Sensor Configuration app
allows modification of the
system without requiring
ladders or tools.
If no
configuration steps are
taken, the sensor will
use its default parameter
values.
The Sensor Configuration app display shows menus
and prompts to lead you through each process. The
mobile app provides a simple way to navigate through
the customization fields.
WIRING
NOTE:
Per UL, the 0-10V negative
dimming wire color has been changed
from gray to pink.
