Introduction

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, H2S, O2, NO2, and combustible hazards.
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.
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.

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 Analytics immediately.
The warranty will be voided if the customer or any unauthorized service personnel attempt to repair the unit.

Installation

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 emission is likely to occur.
CAUTION: Because each sensor can “report” only what it is detecting at the moment, it is very important that the sensor be located where leaks are most 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

Installation Height

Detected Gas		Relative Density	Installation Height
		(air = 1)
CO	Carbon monoxide	0.968	1–1.5 m (3–5 ft.) from floor
H² S	Hydrogen sulfide	1.19	30 cm (1 ft.) from floor
*NO²	Nitrogen dioxide	1.58 (cold)	30 cm–1 m (1–3 ft.) from ceiling
O²	Oxygen	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 NO 2 from exhaust systems is lighter than ambient air.

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.

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 4×4″ 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).

Wiring Diagram

Connecting the Main Sensor to the Remote

Figure 2. Connecting Main Sensor to Remote

The OUT1 and OUT2 connectors on the remote sensor’s terminal are not used. DO NOT connect any wires to these locations.

Wire: Signal wiring should be done with #20-24 AWG shielded twisted pair cable Belden 9841 or similar. Network units should have no more than 2,000 ft (600 m) of #22 AWG wire. Smaller gauge sizes are limited by the same resistance limit. The LED on the faceplate blinks to indicate communication with the main unit.

Maximum over the range is the cell exposure to the gas concentration that may result in permanent damage to the cell.

Sensor Overrange
When Interfacing with the E³Point Main Unit

Sensor over range occurs whenever the gas concentration reading is higher than the full-scale value, no matter how high the gas concentration is.
Overrange Warning state is latched when true. It stays activated indefinitely and is independent of gas concentration reading.
Refer to the E³Point Network or Standalone manual for a description of over range conditions.
