Hazardous Conditions, Poisons, and Contaminants
WARNING: Servicing the unit, replacing or charging battery pack s, or using the co mmu ni cat ions port must only
be done in an area known to be nonhazardous. Not for use in oxygen-enriched atmospheres.
WARNING: Power-off the monitor before servicing the unit or replacing the battery.
WARNING: Substitution of components may impair intrinsic safety and may cause an unsafe condition.
AVERTISSEMENT: La substitution de composants peut compomettre la securite intrinseque.
CAUTION: High off-scale readings may indicate explosive gas concentration(s).
CAUTION: Any rapid up-scale reading followed by a declining or erratic reading may indicate gas
concentration(s) beyond the upper scale lim it w hich may be haz ar dou s.
Silicone compound vapors or other known contaminants may affect the combustible gas sensor and cause
measurements.

Factors that Affect Monitor Performance
Oxygen-deficient atmospheres may cause combustible gas readings to be lower than actual concentrations.
Oxygen-enriched atmosphere s may cau se combu stib le gas readings to be higher than actual concentratio ns.
Sudden changes in atmospheric pressure may cause temporary fluctuations in the oxygen reading.
Verify the calibration of the combustible gas sensor after any incident where the combustible gas content has
caused the monitor to display an over-range con diti on.
Sensor openings and water barriers must be kept clean. Obstruction of the sensor openings and/or
contamination of the water barriers may cause readings to be lower than actual gas concentrations.
Do not use the ISC Alkaline battery pack (P/N:17150608) with the Ventis LS monitor.
The Ventis LS is CSA certified according to the Canadian Electrical Code for use in Class I, Division 1 and
CSA Standard C22.2 No. 152. This is applicable only when the monitor has been calibrated to 50% LEL CH
4.
CAUTION: CSA C22.2 No. 152 requires before each day’s usage, sensitivity must be tested on a known
section of the Product Manual.

Ventis LS Resources
The Ventis LS Product Manual is the primary resource, within a full suite of learning tools, developed for the monitor
user. Its step-by-step “walk through” format covers everything from unpacking to set-up, operation, and service. All
Ventis LS users should read and understand the Product Manual prior to unpacking or using the monitor.
A companion to the manual, the Ventis LS Reference Guide ships with the monitor. It serves to announce all warnings
and cautionary statement s relev ant to gener al mon itor use . The guide also features process charts that provide an
overview of four fundamental tasks: operation/start-up, configuration, calibration, and functional “bump” testing. These
charts are tools for the user who is both familiar with the manual and proficient in the performance of the given t as k.
A collection of audio-visual learning tools is also available online at the Ventis LS Resource Center. Here the user can
watch fully narrated step-by-step demonstrations of instruction sets outlined in the manual. These training modules
allow the user to view the full presentation of a process, such as calibration, or to access a particular segment within
that process. These Ventis LS product-specific resources are part of the organization’s broader training line-up,
featuring face-to-face classroom programs for technicians, operators, first responders, trainers, and distributors.
Courses combine theory with hands-on learning, and can be tailored to the customer’s unique requirements and gas
monitoring applications.
The organization’s customer and technical support call centers provide product and order information, how-to product
assistance, and guidance for in-depth technical applications. Its service centers offer comprehensive factory repair
and maintenance services.
Industrial Scientific Corporation provides a full suite of resources to aid customers in the competent and safe use of
its products and service s. With manufac turing, support, and service centers and hundr ed s of distrib ut ors w orldwide,
Industrial Scientific serves the globe’s gas detection needs.
Ventis LS Capabilities
The Ventis LS is a portable multi-gas monitor. It detects and measures gas(es) present in open space. Its wireless
feature continuously communicates gas readings and alarm events to a control center. Based on the customer’s
monitor order, up to four sensors are factory installed enabling the monitor to continuously and simultaneously detect
and measure the presence of up to four specific gases.
• LEL (Pentane)
• LEL (Methane)
• CO (Carbon Monoxide)
S (Hydrogen Sulfide)
• H
2
• NO
Equipped with a multi-mode (audible, visual, and vibration) and multi-level alarm system, the Ventis LS monitor is
capable of notifying it s user of potentially hazardous gas concentr atio ns. It is also equipped with motion alarms and a
panic alarm.
The monitor performs continu o us datalogging at 10 second intervals. It can store approximately 90 days of data for a
four-sensor configuration. Its date- and time-stamped event log records and stores data for 24 alarm events and a
minimum of 15 error events. The memory, when full, overwrites the oldest data as the newest readings and events
are logged.

The Ventis LS monitor functions as an independent device to monitor the environment for hazardous gas
concentrations. It is also part of the Ventis Syst em including products that charge, calibrate, bump test, datalink,
protect, and otherwise enable or enhance use of the monitor and its data. (Datalink refers to capabilities that enable
access to the download and use of monitor datalogs, reports, and other information.)

NOTICE
→ All monitor alarms and warnings should be taken seriously and responded to as stated in company safety
standards.
It is practical for the monitor user to be aware of the possible alarms prior to monitor set-up and use. The Ventis LS
has multiple alarm and warning signals. A “system level” alarm generates the highest frequency tone and highest
level visual and vibration signals. It is used to indicate such events as a sensor failure. Compared to the system
alarm, gas alarms are of lower intensity, and a quick repetitive burst of signals is used to indicate a panic or motion
alarm. The lowest level indicator is a warning with low-level beep patterns to indicate service needs (e.g., low battery
or calibration due). The beep is also used as a confidence indicator when enabled.
Alarm types and their alarm generating conditions are described below.
the gas concentration value sensed is
above the sensor’s measuring range.
Over-range Alarm Screen
The “Or” message indicates which sensor(s) is reading an over-range
condition(s). All other sensors show their curre nt gas con cen t r ation
readings on a numeric display (left) or gas names on a text display (right).
After any over-range alarm, th e
monitor should be calibrated.
NOTE: The O2 and toxic sensor values normally
reset when the gas sensed reaches an acceptable
range. If the LEL sensor reads over-r an ge, t he
alarm “latches” or remains on until the monitor is
powered-off.
Negative Over-range Alarm Screen
The “-Or” message indicates which sensor is reading a negative overrange condition. All other sensors display their current gas concentration
