Chapter 1 Safety Information
1.1 Safety Information – Read Before Installation and Applying Power
The following symbols are used in this manual to alert the user of important instrument operating
issues:
This symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions.
This symbol is intended to alert the user to the presence of dangerous voltage within the
instrument enclosure that may be sufficient magnitude to constitute a risk of electric
shock.
WARNINGS:
•WARNING- EXPLOSION HAZARD -DO NOT REPLACE FUSE UNLESS POWER HAS BEEN SWITCHED
OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS.
•WARNING- EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN
SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS.
•Use a properly rated CERTIFIED AC power (mains) cable installed as per local or national codes
•A certified AC power (mains) disconnect or circuit breaker should be mounted near the
controller and installed following applicable local and national codes. If a switch is used instead
of a circuit breaker, a properly rate CERTIFIED fuse or current limiter is required to be installed
as per local or national codes. Markings for positions of the switch or breaker should state (I)
for on and (O) for off.
•Clean only with a damp cloth without solvents.
•Equipment not used as prescribed within this manual may impair overall safety.

Chapter 2 General Description
The SensePoint gas detector is a 120-240VAC, or
10-30VDC, powered gas detector for toxic,
oxygen, combustible, VOC and CO2 detection,
with a color backlit LCD display, 4-20mA output,
Modbus communications and relays.
All models use RC Systems latest Generation II
Smart Sensor technology, providing smarter gas
detection with simplified solutions.

Chapter 3 Installation Instructions
3.1 Selecting a Location
Factors such as air movement, gas density in relation to air,
emission sources and environmental variables affect correct
sensor location.
Air movement by fans, prevailing winds and convection should
be carefully evaluated to determine if a leak is more likely to
raise gas levels in certain areas within the facility.
Vapor density of a gas determines if it will rise or fall in air when
there are no significant currents. Lighter than air gases should
have the detector mounted 12 to 18 inches (30 to 45 cm) above
the potential gas leak, and heavier than air gases should be this
distance below the potential gas leak.
The Universal Series of gas detectors are designed for
rugged service in the field. However, sensors should
always be protected from environmental damage from
water, snow, shock, vibration and dirt.

3.2 Mounting the Enclosure
Install the detector to a wall or bracket using the predrilled mounting flanges shown in
Figure 1. If remote sensor option is included see Figure 2 for mounting dimensions of the
sensor housing.
After you have determined the appropriate location for your gas detector, it is important to securely
mount the gas detector using the predrilled mounting flanges on the enclosure (Figure1). Dimensions
for the mounting holes can be found for both the aluminum and poly enclosures in Figure 2.
