Warning
Read Before Operating
This manual must be carefully read by all individuals who have or will have the
responsibility of using, maintaining or servicing this product. The product will perform as
designed only if it is used, maintained and serviced in accordance with the
manufacturer’s instructions. The user should understand how to set the correct parameters
and interpret the obtained results.
CAUTION！
Remove the monitor cover only in area known as non-hazardous.
CAUTION: HIGH OFF-SCALE READINGS MAY INDICATE AN EXPLOSIVE
CONCENTRATION.
ATTENTION: DES LECTURES SUPÉRIEURES A L’ÉCHELLE PEUVENT INDIQUER
DES CONCENTRATIONS EXPLOSIVES.
WARNINGS
ONLY THE COMBUSTIBLE GAS DETECTION PORTION OF THIS INSTRUMENT
HAS BEEN ASSESSED FOR PERFORMANCE.
UNIQUMENT, LA PORTION POUR DÉTECTOR LES GAZ COMBUSTIBLES DE CET
INSTRUMENT A ÉTÉÉVALUÉE.
CAUTION: BEFORE EACH DAY’S USAGE, SENSITIVITY OF THE COMBUSTIBLE
GAS SENSOR MUST BE TESTED ON A KNOWN CONCENTRATION OF METHANE
GAS EQUIVALENT TO 20 TO 50% OF FULLSCALE CONCENTRATION. ACCURACY
MUST BE WITHIN 0 AND +20% OF ACTUAL. ACCURACY MAY BE CORRECTED
BY CALIBRATION PROCEDURE.
ATTENTION: AVANT CHAQUE UTILISATION JOURNALIERE VERIFIER LA
SENSIBILITE AVEC UNE CONCENTRATION CONNUE DE METHANE
EQUIVALENTE A 20-50% DE LA PLEINE ECHELLE. LA PRECISION DOIT ETRE
COMPRISE ENTRE 0-20% DE LA VALEUR VRAIE ET PEUT ETRE CORRIGEE
PARUNE PROCEDURE D’ETALONNAGE.
Warning: High off-scale readings may indicate an explosive concentration.
Warning: Substitution of components may impact intrinsic safety.
Note: Users are recommended to refer to ISA -RP12.13, Part II-1987 for general
information on installation, operation, and maintenance of combustible gas detection
instruments.

WARNINGS
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Caution: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
—Reorient or relocate the receiving antenna.
—increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
—Consult the dealer or an experienced radio/TV technician for help.
Proper Product Disposal at The End Of Life
The Waste Electrical and Electronic Equipment (WEEE) directive
(2002/96/EC) is intended to promote recycling of electrical and
electronic equipment and their components at end of life. This symbol
(crossed-out wheeled bin) indicates separate collection of waste
electrical and electronic equipment in the EU countries. This product
may contain one or more Nickel-metal hydride (NiMH), Lithium-ion, or
Alkaline batteries. Specific battery information is given in this user
guide. Batteries must be recycled or disposed of properly. At the end of
its life, this product must undergo separate collection and recycling
from general or household waste. Please use the return and collection
system available in your country for the disposal of this product.

1. General Information
The POLI multi-gas detectors (MP400, 400P & 400S) offer 4 or 5-gas monitoring of
oxygen (O2), combustible (LEL), toxic, carbon dioxide (CO2) gases and volatile organic
vapors (VOCs). The MP400 is a compliance model of O2, LEL, carbon monoxide (CO)
and hydrogen sulfide (H2S) configuration in diffusion. The MP400P is a standard model
and adopts a full range of sensor selection, e.g. electrochemical (EC), pellistor,
non-dispersive infrared (NDIR) and photo-ionization detector (PID) in pump or diffusion.
The MP400S is an advanced model and has a built-in wireless module that sends critical
data of Man Down, Gas and Battery Alarms to supervisors and control centers on site or
at remote locations for faster responses and maximized safety measures.
1.1 Main Features
⚫3 models of diffusion, pump and wireless optimized for compliance, professional and
advanced applications.
⚫Large graphical display icon-driven user interface through intuitive,
simple-to-operate two-button user interface
⚫Over 30 interchangeable sensor configurations, including PID for VOC, NDIR and
catalytic for combustibles, and NDIR for CO2
⚫Intelligent sensors store calibration data ready for installed in the field
⚫Easy access to pump, sensor, filter and battery
⚫Man Down, Gas and Battery Alarm notification via ISM wireless at a free of charge
⚫IP-65/67 water and dust resistant case

2. User Interface
The POLI’s user interface consists of two (2) keys, four (4) sensor sockets, one (1) big
LCD - Liquid Crystal Display, eight (8) alarm LEDs - Light Emitting Diodes, one (1)
buzzer, and two (2) vibration alarms.
2.1 Displays and Keys
The LCD provides visual information that includes real-time gas readings, sensor types,
datalog / battery / pump / wireless status, and others.

2.1.2 Auto Flip Screen
When positioned up down, the POLI screen is automatically flipped for keeping normal
readings.
2.1.3 Keys and Interfaces
The POLI has two keys:
[+/OK] Key [/↓] Key
Confirm/Number Increase Power/Cursor

Moving
These two keys are marked as [+/OK] and [ /↓] for Confirm or Number Increase and
Power / Cursor Moving, respectively. They also act as ‘soft keys’ that changes numbers
and make selections under various menus.
Two test and symbol boxes at the LCD bottom are ‘mapped to’the [+/OK] and [ /↓]
keys. The text and symbol in the boxes may vary with the menu.
In addition to the functions described above, either key can be used to manually activate
LCD backlighting. Press a key to turn it on when the backlighting is off.
2.2 Active Sensor Displays
Though having four (4) sensor sockets, the POLI is a flexible platform that
accommodates one (1) to five (5) sensors with a dual toxic sensor. When one or more
sensors is either not installed or turned off, the display only shows the installed, active
sensors:
