Introduction
Safety Information
Introduction
The ToxyPoint gas monitor provides continuous monitoring for carbon
monoxide (CO) hazards in ambient air. The monitor is a 2-wire, 4-20mA
transmitter with sensor. It is factory calibrated and tested and has a
maximum operating life of 3 years.
Safety Information
Users of the ToxyPoint 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.
• Install according to local electrical regulations and codes.
• Installation should be performed by qualified personnel.
• Do not paint over the sensor screen.
• Do not activate the monitor after the date on the package.
• Make sure the sensor screen is free of dirt and debris.
• Make sure 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, missing metals or plastics. If the monitor is
damaged, contact Vulcain immediately.
• The warranty will be voided if the customer or any unauthorized
service personnel attempts to repair the unit.
• The ToxyPoint should be interfaced to a Class 2 or Limited circuit.
A limited circuit is a circuit supplied by sources such as a battery or a
transformer winding where the open-circuit potential is not more than 30
V r.m.s or 42.4 V.d.c., and the energy available to the circuit is limited
according to one of the following:
The current under any condition of load, including short circuit, is not
more than 8A measured after 1 minute of operation;
The source is RATED or set to limit its power output to 150 VA under any
condition of load including short circuit;
An overload protector or circuit component opens to interrupt the power
output at a lower value than 150 VA under any condition of load including
short circuit.

Introduction
Sensor Installation Locations
Sensor Installation 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 As a rule, at least one sensor should be located in
Sources: close proximity to each point where an emission is
likely to occur.
Height: We suggest, dependent of air currents, that the
ToxyPoint be installed at approximately 3 to 5 feet
above ground or higher where CO emission is likely
to accumulate.

Mounting the Enclosure
ToxyPoint is mounted in a standard single outlet (gang1) electrical box
supplied by the customer. The ToxyPoint Mounting Plate fits boxes
mounted in drywall (new construction) or is surface mounted.
The diagram below provides installation and mounting heights.

Introduction
Cable Installation
Cable Installation
The distance the 4-20 mA signal can travel is dependent on several
factors including cable gauge. Maximum cable resistance is 650 ohms
less the controller resistance.
The table below assumes a constant 24 volt power supply (at 20C),
copper wire and a Controller resistance of 250 ohms. The signal range
from the Controller/PLC etc. to the ToxyPoint takes into account the
return loop. The distance shown is from the Controller to the
Transmitter.
Maximum Cable Lengths Between Controller and ToxyPoint
Conductor size Distance
22 AWG 0.64 mm 2,045 m (6,715 ft)
20 AWG 0.75 mm 3,253 m (10,953 ft)
18 AWG 1.00 mm 5,167 m (16,953 ft)
Recommended: Use shielded cable, or cable in conduit to
avoid electrical interference. The shield (including mylar)
must be grounded. Keeping the shield as short as possible,
tie the shield and extra wires to the electrical box grounding
screw. Pull 2-wire cable into the enclosure(s).
Output Signals: If accessing the output signal(s) at O/P1
and/or O/P2 additional wire(s) will be required from the
sensor. Wire as shown in the Alarm Outpus Installation
diagram.
