E3Point Gas Monitor Technical Manual
Introduction

Introduction
E3Point derives its name from: Energy Management, Efficiency, and Economic
value in gas detection.
E3Point is an important part of toxic or combustible gas detection system that
combines a gas sensor (electrochemical or catalytic type), a control unit, and a set
of outputs (such as 4-20 mA current loop, buzzer and relays). The polycarbonate
housing is resistant to rust, dents and corrosion.
There are 3 monitor models in the E3Point family: Standalone, Remote and
Network. The Standalone monitor provides the full control unit, with a built
in sensor and is capable of accepting one additional Remote sensor. This
configuration allows the E3Point to detect two gases in two separate locations.
The E3Point Network platform supports different protocols over an RS-485 link,
such as Modbus or BacNet MS/TP master. It is well suited for commercial use in
parking garages and mechanical rooms. It is intended for connection to the 301-C
or AA96D series contollers.
Installation is both economical and efficient because it is achieved in 3 easy steps
(mounting, wiring and power-up). Units are shipped with a Quick Start Guide to
support proper installation.

Installation
!
WARNING: Some materials such as, but not limited to, tetraethyl lead,
silicones, some sulfur, phosphorus, and chlorinated compounds, may have a
poisoning effect resulting in a loss of sensitivity. Avoid installing the monitor
in areas where these materials may be present.
Locating the Sensor
Considerations in locating the monitor
Instalation Height:
•Fastest Possible Leak Detection – Mount the monitor near the
potential leak sources
- One monitor should be located in close proximity to each point where
an emission is likely to occur
- Indicated concentration may not be representative of personnel
exposure
- Easy access for the required calibration and maintenance could be
compromised
•Personnel Protection
– Mount the sensor at the installation heights shown in the table below
–Gas is detected where it is accumulated – which may not be detected
at the leak source.
Air Currents: If there are fans, wind, or other source 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.
!
CAUTION: Because each sensor can only “report” what it is
detected at the place it is installed at a specific moment, it
is very important that the sensor be located where leaks
are most likely to occur.

Installation Height
Detected Gas Relative Density Installation Height
(air = 1)
CO Carbon monoxide 0.968 1–1.5 m (3–5 ft.) from floor
H2SHydrogen sulfide 1.19 30 cm (1 ft.) from floor
*NO2Nitrogen dioxide 1.58 (cold) 30 cm–1 m (1–3 ft.) from ceiling
O2Oxygen 1.43 1–1.5 m (3–5 ft.) from floor
COMB Most combustibles are heavier than air, with the exception of methane,
hydrogen, ethylene and acetylene. Sensors for gases that are heavier
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 NO2from exhaust systems is lighter than
ambient air.
Wall Mounting for Standalone/Network monitor
1. Verify that power to the monitor is off.
2. While properly grounded for ESD protection, remove the PCBA from the
monitor. It is attached by a single center screw. Carefully place the PCBA
in the enclosed antistatic envelope.
3. Drill two holes through the case and into the mounting surface;
