Description
The E³Point Remote Sensor is a toxic or combustible gas detection
sensor that is compatible with the E³Point Standalone sensor. The
sensor provides continuous monitoring for one of the following gases
in ambient air: CO, H
The E³Point is designed to be mounted on an extra wide (2 3/8”)
electrical box.
The E³Point Remote Sensor is intended for connection to E³Point,
Class 2, or limited power source (lps) only.
Safety Information
Users of the E³Point Remote Sensor require a full understanding of
the installation, operating, and maintenance instructions, otherwise
protection provided by the monitor may be impaired. Read the
following warnings before using the monitor.
Introduction
2S, O2, NO2, and combustible hazards.
Attention
This manual must be carefully followed by all individuals who
have the responsibility for using or servicing the sensor. Warranties
made by Honeywell Analytics with respect to this equipment will
be voided if the equipment is not used and serviced in accordance
with the instructions in this manual. Additionally, equipment
functionality and inherent protection may be compromised if this
manual is not carefully followed. If in doubt about a procedure,
contact Honeywell Analytics before proceeding.

Introduction
Warnings
WARNING:
•
Install according to local electrical regulations and codes.
•
Installation should be performed by qualified personnel.
Do not paint over the sensor screen
•
•
Ensure that the sensor screen is free of dirt and debris.
Ensure that the sensor screen is not covered.
•
•
Do not expose the monitor to electrical shock and/or
continuous mechanical shock.
•
Do not expose the sensor to high-pressure water spray.
•
Do not use the monitor if it is damaged. Before use, inspect the
monitor. Look for cracks and missing metals or plastics. If the
monitor is damaged, contact Honeywell Ana lyt ics immediately.
•
The warranty will be voided if the customer or any unauthorized
service personnel attempt to repair the unit.

Sensor Locations
The following suggestions should be considered to assure detection
of the target gas. Select the most suitable location for each sensor.
Air Currents: If there are fans, wind, or other sources of air
movement, gases may tend to rise or collect in certain areas of a
facility. The local air currents should be assessed to aid in selecting
the sensor location. Air convection can often be more important in
determining gas concentration areas than factors of Vapor Density.
Gas Emission Sources: As a rule, at least one sensor should be
located in close proximity to each point where an emission is likely to
occur.
This unit is intended for
• Indoor use
• Maximum altitude 2000 m
• Overvoltage Category II
• Pollution degree 2
• E³Point, Class 2, or limited power source (lps) only

COMB Most combustibles are heavier than air, with the exception of methane,

than air should be installed approximately 30 cm (1 ft) from the floor.
For combustibles that are lighter than air, sensors should be installed
30 cm (1 ft) from the ceiling, close to the potential leak source.
* May differ in certain applications. Hot NO from exhaust systems is
lighter than ambient air.

Wiring Diagram
Mounting
The E³Point Remote Sensor is designed to be mounted in an extra
wide (2 3/8”) electrical box (not supplied) in the same way as a
faceplate. Suggested electrical boxes include T&B BC1110, Hubbell
1110, OZ-Gedney 18112, Appleton 18112, Bowers 10612-BW, or
Steel City 68371-12.
It does not fit on 4x4” steel boxes with a single gang mud ring, such
as T&B 52CO or 52C13.
Run the wires through the electrical box and connect to the
remote sensor (as indicated in Figure 2
Press the sensor (2) into the faceplate (1) and close and press
the back cover (3) into the faceplate. You should hear a click.
Securely mount the unit to the extra wide electrical box (4) using
the appropriate screws (5).
