E3Point Gas Monitor Technical Manual
Introduction
1
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.

Warnings and Cautions
2
Warnings and Cautions
Warnings
•Power to the E3Point monitor must be off during installation and when
installing the sensor cartridge.
•The installer must be grounded for ESD protection while handling the PC
board (PCBA) and during installation of the monitor.
•Follow all local codes when installing the monitor.
•Operate, service, and use the monitor only as specified in the quick start
guide and this technical manual. Failure to do so may impair the protection
the monitor is designed to provide and may also void the warranty. The
manual is available on the Honeywell Analytics website. You may scan the
QR code below for easy access to product information:
•Calibration, set-up, and test modes are intended for use by trained personnel
and service engineers only. Access to these modes is passcode protected.
•Follow local and site procedures when working with this monitor. If applicable,
verify that the associated control panel is inhibited in order to prevent false
alarms during installation. The procedures in the quick start guide and the
product’s technical manual must be followed carefully and performed only
by trained personnel and service engineers.
•Use only accessories and parts meeting or exceeding Honeywell Analytics’
specifications.
•Some monitors require warm-up time. See the appropriate sections in this
technical manual for specific information.
•Ensure that the monitor screen is free of dirt and debris, and do not cover
or paint over the monitor screen.
•Do not expose the monitor to electrical shock and/or continuous mechanical
shock.
The warranty will be voided if the customer or any unauthorized service
personnel attempt to repair the monitor

Warnings and Cautions
3
Cautions
•The E3Point monitor must be installed only by trained personnel and service
engineers in accordance with local codes.
•The safety of any system incorporating the E3Point monitor is the responsibility
of the assembler of the system.
•Protect the monitor from water, wash-down, and excessive humidity.
•To prevent electrical interference, keep the monitor and wire runs away from
mercury vapor lights, variable speed drives, and radio repeaters.
•Protect the monitor from physical damage (fork lifts, etc.).
•Do not mount the monitor over a door in a refrigerated area.
•For critical locations, more than one monitor should be installed in each room.
•Never mount the sensor flat on a ceiling.
•Never mount the sensor on a vibrating surface.

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;
horizontally if mounting on a vertical surface or vertically if mounting to a
standard electrical box as indicated below.

for mounting on
vertical survaces
3.28 in (8.3 cm)
for mounting on electrical boxes
