Wireless Switch 

Installation 

Guide

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.

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):
