Introduction

The Ei1020 and Ei1025 are Environmental Sensors for indoor use. They
measure CO2 levels (Ei1025 only), temperature and humidity. They are
wireless and powered by a non-replaceable lithium battery. Any data
collected by the sensors is uploaded via the SmartLINK Gateway to a
portal where the information is displayed.

The Environmental Sensor must be installed in accordance with the
instructions given in this manual.

Any use other than that described in this manual is seen as unintended
use.

Please read the manual in full before installing the Environmental
Sensor.

1. Obstructions of any sort will result in a reduction in range from the free
space specification. The range may vary depending on installation.

2. Temperature and humidity conditions are for normal operation and
storage. Units will function outside these ranges as required by the specific
product Standards. Extended exposure to conditions outside these ranges
can reduce product life. For advice on prolonged operation outside these
ranges consult the manufacturer.

Installation

IM P O R TANT: A SmartLINK Gateway must be present and fully
operational in the dwelling.

IM P O R TANT: To install the Environmental Sensor, you must have
access to that Gateway in the SmartLINK app.

Location

The sensor s can be installed in any room. However, some of the information
the sensors collect is room specific as detailed in the table below:

Ensure when installing the Environmental Sensors, that the location
selected is appropriate to the information sought.

The sensors are designed to be wall/ceiling mounted:
a. At approximately 1.4m from the floor level (for wall mounting)
b. At least 300mm from any walls or corners where there is dead air.
c. At least 300mm from any obstructions (eg. light fitting, decorative

object, furniture, curtains, etc...)

d. in free space.
Do NOT install:
a. Next to or directly above sources of Heat (such as cookers, heaters,

etc…).

b. Next to or directly above air conditioning vents, windows, wall

vents, etc…

c. In areas where it may be exposed to water splashes, dripping or

condensation (e.g. sink, above an electric kettle, etc…).

d. In direct sunlight.

Mounting

WARNING: to prevent injury, this device must be securely attached

to the wall or ceiling in accordance with the installation instructions.

Figure 2

IM P O R TANT: Make sure the mounting bracket is positioned so that
the text is at the top.

Adding the Environmental Sensor

to the Gateway System

Open your SmartLINK App available to download from the Google Play
or iTunes app store and simply follow the steps in the SmartLINK App.

Remove the mounting bracket
from the packaging.

Place the mounting bracket exactly
where you want to mount the
sensor. With a pencil, mark the
location of the two screw holes.

Taking care to avoid any electrical
wiring, drill holes using a 5.0mm
drill bit through the centre of the
marked locations. Push the plastic
screw anchors provided into the
drilled holes. Screw the mounting
bracket to the wall/ceiling (see
figure 2).

RF Communication

Ei Electronics radio communication systems are very reliable and
are tested to high standards. However, due to their low transmitting
power and limited range (required by regulatory bodies) there are
some limitations to be considered.

Receivers may be blocked by radio signals occurring on or near their
operating frequencies.

The numbers of walls, ceilings and metal objects in the signal path can
also reduce the strength of the signal.

If you get an error and the Environmental Sensor does not register
with the Gateway, try a different location. If the problem persists,
please contact us at the nearest address at the end of this manual.
