QMI TRIPLEX™
Atmospheric Oil Mist Detection System Manual
TM4 / AUGUST 2018
You have chosen a QMI oil mist detection system that has been providing a fast
response without false alarms to protect lives and prevent fires since the early
eighties.
The QMI TRIPLEX™ Atmospheric Oil Mist Detection Systems can locate a hazardous
build up of oil mist in confined areas such as: pump rooms, bow thrusters, purifier
rooms, hydraulic pack areas, and test cells.
We can provide QMI MULTIPLEX™ Atmospheric and Engine Oil Mist Detection
Systems. The MULTIPLEX™ systems have up to 12 channels and can be used to
monitor engine condition continuously to see when and where repairs are needed
thus avoiding unnecessary engine wear and the resulting danger. The MULTIPLEX™
can also be used for larger Atmospheric Systems. For more information please see

The Monitor Enclosure contains:
Display Panel
Power Supply Board (PSB)
Plugs and sockets for relevant connections
Fuses
Keyed Security Switch
The Display Panel
The display panel is mounted on a hinged bezel which is secured to the enclosure
by (4) M6 Captive socket head screws. Releasing the screw allows access to the
TRIPLEX PCB and the power supply board within.
TRIPLEX PCB (Q01T04)
The back of the display panel carries the Triplex MP3 Processing Board, Binary Switch
and Flash Chip. The PCB is held to the panel with (5) M4 cheese head screws.
Power Supply Board (Q01T05) with PSU
Mounted on the board is a Power Supply Unit, fuses, TR1 transistor, alarm relays, and
termination sockets.
NOTE:
THE PLUGS ARE SHAPED AND CAN ONLY BE FITTED ONE WAY.
INCORRECT FITTING DAMAGES THE SOCKET CAUSING UNIT MALFUNCTION.
Fuses
FS1 (Q0114) is a 1.25A anti-surge fuse connected to TR1 and supplies the
Sensor. The LED continually flashes in operation.
FS2 (Q0112) is a 400mA anti-surge fuse for the 12V power supply to the fan.
The LED is permanently lit in operation.
FS3 (Q0115) is a 3.15A anti-surge fuse (in a holder) fitted to the side of the
Monitor.
Security Key Switch on the right side of the Monitor.
THE SECURITY KEY IS REQUIRED TO CHANGE SETTINGS.
HORIZONTAL = LOCKED MODE
VERTICAL = SETTING MODE
NOTE:
THERE IS NO MAINS ISOLATOR FITTED TO THE MONITOR.
QMI RECOMMEND A SECURE MAINS ISOLATOR IS FITTED TO PREVENT POWER
INTERRUPTION TO THE SYSTEM.

DESCRIPTION OF Q10 ATMOSPHERIC SENSOR
See drawing Sheet-10
The Sensor operates using the principle of light scatter (nephelometry). The power
and signal are transmitted to and from the Monitor through a single cable sending a
timed analogue signal. All Sensors sample simultaneously and continuously every half-
second (500 milliseconds).
The assembled Sensor comprises:
(a) Articulated Joint and mounting flange
(b) Chamber
a) ARTICULATED JOINT AND MOUNTING FLANGE
See drawing Sheet-10
The Articulated Joint is fitted to bulkhead or deck allowing the Sensor to be positioned
facing the flow of air in the chamber being monitored.
The sub-assembly is fitted to the Articulated Joint by 4 screws, which can be removed
if and when the Sensor lens requires cleaning.
b) CHAMBER
Inside the unit are the PCB, integral fan, and sensing lenses. Power is supplied to the
12-volt fan by a single cable, which is connected to the
Monitor (or to a junction box). The fan draws the sample of air past the sensors
through the outlet ports.
In the front of the Sensor unit are the air intake louvers, and an LED, which shows
green when the fan is working. The electronics are mounted on the back of the
chamber casing and are protected by the cover sealed to IP 65.
At the back of the unit is the multi-purpose power and signal socket. Next to the
socket is the mounting spigot.
NOTE: The integral fan is interchangeable without recalibrating the Sensor.
It is a consumable item and does not come under warrantly. New Fans can be
purchased from your Agent.
