E3Point Standalone Gas Monitor User Manual 1
Introduction
Introduction
E3Point is:Energy Management, Efficiency, and Economic value.
E3Point is a toxic or combustible gas detection system that integrates the
best functionalities from well-known Honeywell Analytics products, such
as the 201M, 201T and 301M. Although new and innovative, E3Point is
still compatible with the features offered in these products.
The E3Point gas detection system 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) in one reliable and
robust product. The polycarbonate housing is resistant to rust, dents and
corrosion.
In addition to its built-in sensor, the E3Point Standalone monitor 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 certain outdoor environments, and indoor
environments, such as parking garages and mechanical rooms.
Installation is both economical and efficient because it is achieved in
3 easy steps (mounting, wiring and power-up). Units are shipped with
custom diagrams, indicating the most effective places to mount units.

Installation
Locating the Sensor
Since the E3Point units are shipped with custom network diagrams that
indicate best locations for installation, the remaining considerations are
installation height and detection objectives. If the primary application is
the fastest possible leak detection, mount the sensor near the potential
leak sources. As a result, the indicated concentration may not be
representative of personnel exposure, and easy access for the required
calibration and maintenance can be compromised.
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.

CAUTION:Because each sensor can only “report”what it is seeing
at the 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
H2S Hydrogen 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.

W ARNING:Some materials such as, but not limited to, tetraethyl lead,
silicones, some sulfur, phosphorus, and chlorinated compounds, may
have a poisoning eect resulting in a loss of sensitivity.
W all Mounting
Mounting is usually done on concrete walls or columns, but the unit
can be mounted on any vertical surface. The housing is designed with
spacers on the back to allow moisture to flow behind the housing without
affecting the unit.
tMounting holes are located inside the housing. Open the unit to
access mounting holes.
tDrill and mark the holes, as shown:
- W idth 11.1 cm (4 3/8”) apart (if mounting directly to wall)
- Height 8.3 cm (3.281”) for electrical boxes
11.1 cm (4 3/8”)
8.3 cm
(3.281”)
Figure 1. Unit Dimensions
tPre-drill mounting holes from the back of the unit as needed.
tSecurely mount the unit using the appropriate screws and
anchors. The unit is designed to use #6 screws. Tighten to 8.7
in-lb (1 Nm) maximum.

4 E3Point Standalone Gas Monitor User Manual
Installation
tClose the unit cover and tighten screws to 29.7 in-lb (3 Nm).
tDo not remove PC board when removing knockouts.
tKnockout on back is not for conduit entry.
General Mounting Considerations:
tMust be easily accessible for calibration and maintenance.
tMount the sensor close to the potential leak source for fastest
possible leak detection.
tIf personnel protection is the primary application, mount in the
“breathing zone”(1–1.5m from the ground, within the range of a
person’s respiration area).
tProtect the sensor from water, excessive humidity, and wash-
down.
tTake air movement and ventilation patterns into account.
tTo prevent electrical interference, keep sensor and wire runs
away from mercury vapor lights, variable speed drives, and radio
repeaters.
tProtect the sensor from physical damage (fork lifts, etc.).
tDo not mount the sensor over a door in a refrigerated area.
tFor highly critical locations, more than one sensor should be
installed in each room.
Very Important:
tNever mount the sensor flat on a ceiling.
tNever mount the sensor on a vibrating surface.

Guidelines
Electrical wiring must comply with all applicable codes. Operating
conditions and site equipment that may be involved should be discussed
with local operating personnel to determine if any special needs should
be considered.
Ground the shield at the main control panel. Connect the shield wire in
the sensor terminal block labelled shield. Tape all exposed shield wire at
the sensor to insulate it from the enclosure.
Electrical Power:24 VDC/VAC nominal, 0.35 amp maximum. Either AC
or DC may be connected to the terminal block.
Output:Circuit board mounted sensor provides a linear 4-20 mA output.
Monitoring equipment may have a maximum impedance of 500 ohms.
W ire:Signal wiring should be done with #20-24 AW G shielded twisted
pair cable Belden 9841 or similar. Network units should have no more
than 2,000 ft (600 m) of #22 AW G wire. Smaller gauge sizes are limited
by the same resistance limit.
Power wiring should be sized by local codes, but never less than #20
AW G. 120 VAC wiring should be #14 or #12 AW G.

Installation Test
Installation Test
Once the unit has been mounted and all wiring connections are
complete, a test of the unit’s functions is recommended. It is necessary
to access the unit’s programming menus to perform the test:
tPower up the unit and allow 5 minutes for the warm-up
procedure to complete (allow 15 minutes for the O2sensor).
tPress the enter on the front touchpad.
tThe LCD displays the Password login screen. See Password
Menu.
Once in the programming menus, use the arrow key to scroll to the
TestMode option. See TestMode Menu.
The TestMode menu performs a test of all functions on the unit. All
outputs are activated according to their failsafe mode, relay setting, and
buzzer setting. All functions are activated simultaneously for a maximum
of 3 minutes (or until the user cancels the test) to ensure working order.
The unit does not detect gas during this TestMode procedure.
Once all functions are confirmed in good working order, the unit is
completely functional.
Should any function fail the test, verify that all connections are correctly
wired and re-test.

Operation
The E3Point gas detection system is factory configured to conform
to specific standards. It is designed to be operational after physical
installation and warm-up procedures.

Operation
Sensor W arm Up
W hen the unit is first powered up, sensors must go through a 5 minute
warm-up (15 minutes for the O2sensor), during which time the unit
displays W arm-Up. The 4-20 mA is maintained at 4 mA for all sensors;
however, the O2sensor is maintained at (approximately) 17.4 mA (equal
to 20.9%).
Allow the sensor to operate for 12 hours with the enclosure closed prior
to testing the sensors. Optimal sensor performance is achieved 3 to 4
hours after initial power up.
User Interface
The E3Point gas detector is equipped with a 2 line, 8 character LCD
screen that displays reading information and serves as an interface for
programming functions and calibration.
