Supported Models and Requirements
Europe: EFLS102/N1W | UK: EFLS102/N1W
This device requires a neutral AC connection.
This device requires a 4-position terminal block in its wall box.
Specifications and Supported Fixtures
This switch operates independently or as a device you can control with your
Escient
®
system. It installs in a standard wall box using typical wiring
standards and communicates to the Escient system using a wireless
connection. The specifications and supported fixtures are described below.
WARNING! Improper use or installation can cause SERIOUS
INJURY, DEATH or LOSS/DAMAGE OF PROPERTY.
WARNING! Install in accordance with all national and local
electrical codes.
WARNING! If you are not sure which wires are Hot, Neutral, Load
or Ground, have a trained electrician do the installation.
CAUTION! Do not install to control a receptacle.
CAUTION! If you are not sure which wires are Hot, Neutral, Load or
Ground, have a trained electrician do the installation.
IMPORTANT! Using this product in a manner other than outlined in
this document voids your warranty. Further, Escient is NOT liable for
any damage incurred with the misuse of this product. See “Limited 2
Year Warranty.”
IMPORTANT! Do NOT use a power screw driver to install this
device.
IMPORTANT! Changes or modifications not expressly approved by
Escient could void the user’s authority to operate the equipment.
Installation Instructions
1 Ensure that the location and intended use meet the following criteria:
• The range and performance of the wireless control system is highly
dependent on the following: (1) distance between devices; (2) layout of the
home; (3) walls separating devices; and (4) electrical equipment located near
devices.
• DO NOT exceed maximum load rating of switch (which is 1000 Volt for a
single unit).
WARNING! Disconnect power before installing or servicing the
device.
2 Switch off and isolate the mains power at the main consumer
unit or fuse box before starting any installation or maintenance
work.
3 Prepare the wall box and wires:
• Ensure a 4-position terminal block is installed in the box.
• Strip each wire’s insulation back 7.3 mm (0.287 in.) from the wire end (as
shown).
WARNING! This is a Class 1 product and must be Earthed.
4 Identify and connect switch wires to the wall box wires. Wall box wires
can differ depending upon how the box was wired by the electrician and
where the power source comes from—either the light fixture or the wall
box. Refer to “Sample Wiring Configurations”.
5 Fit wires back into the wall box. Bend the wires in a zigzag pattern so
that they easily fold into the wall box.
6 Connect the switch terminal block to the wall box wires as indicated in
“Sample Wiring Configurations.”
Note: Wall box wires can differ depending upon how the box was
wired by your electrician.
7 Secure the switch to the wall box using the screws
provided.
8 Attach the Decora-style screw-on wall plate (included).
WARNING! Do not turn power back on until the
wall plate is completely back in place.
9 When installation is complete, turn on the mains power.
10 Ensure that all LEDs on the front are lit.
Sample Wiring Configurations
Single-Location Scenario—Power Source at Wall Box
Note: This device will not function without a neutral AC connection.
To wire the switch for a Escient single-location scenario in which the power is
first routed to the wallbox, use a 4-position terminal connector to connect the
wires indicated in the following table (illustrated in Figure 2):
Two-Location Scenario—Power Source at Wall Box
Note: This device will not function without a neutral AC connection.
To wire the switch and a multi-button keypad in a two-location scenario
(Escient’s 3-way-switch solution) where the power is first routed to the wall
box, do the following:
1. Wire the switch into Wall Box #1 by using a 4-position terminal connector
to connect the following wires (illustrated in Figure 3):
2. Wire the multi-button keypad into Wall Box #2 by using a 3-position (or
greater) terminal connector to connect the following wires (illustrated in
Figure 3):
