1. INTRODUCTION
The FORENSICS DETECTORS FD-60 FIXED GAS DETECTOR is the most
advanced wall mount fixed gas detector available and adopts an advanced
electrochemical gas sensor which can detect the gas concentration in the
air to a digital readout signal output. The detector can be used to detect
gas in various industrial environments such factory, refinery, chemical
plant, process rooms, exhaust prone facilities, toxic gas exhaust and
rooms, boiler rooms, painting plants/rooms and other places where toxic
gas exists. Please note, these type of detectors are referred to as “fixed
gas”, since they are fixed at one location when mounted.

4. OPERATION
SETUP: Unbox detector. Identify your power source. The detector
comes with a power supply that connects to the power cord. To set up
the detector remove the 5 hex screws with the hex driver provided.
Ensure (1) the power cable is secured on the PCB (2) connect the
LED/BUZZER fixture (3) sensor assembly is secure. Please note, for
flexibility the power cable and alarm LED/BUZZER fixture can be
swapped on either side to accommodate installation and aesthetics.
4.1 Turn ON/ OFF
Connect 24V power to the detector. The detector enters a 60-second countdown.
Once complete, it then enters into normal detection mode. Once first ON, allow 30
minutes for the gas detector to stabilize then the data displayed in the main display is
the gas concentration value of instantaneous detection. The detector has been
FACTORY calibrated. Hence, it is NOT necessary to perform any CALIBRATION,
however do ensure ALARMS are set to the users satisfaction and local exposure limit
requirements (as necessary per your safety officer advice or consult with local, state
or federal authorities). The detector can be turned off by directly disconnecting the
power supply. We recommend BUMP testing to confirm operation of alarms.
4.2 Menu Item Operation Description
The detector should be operated and controlled via the remote control. Otherwise, one
can use the detector button control on the main panel, but will need to remove the
cover. To do so, with the hex screwdriver delivered, unscrew 5 screws to open the
metal cover and display 4 buttons: return, up, down, and OK. Three operation
interfaces:
1. Detection interface
2. Function menu
3. Parameter setting interface.

5.3. “ALARM SET” Menu
Users can use this option to set the warning value and alarm mode. The detector is
equipped with two alarm point settings. The alarm modes are LOW alarm and HIGH
alarm values. The corresponding two sets of relays are triggered/switched. The
instrument is in a LOW alarm state when the detected concentration is higher than
the set LOW detected concentration value. The instrument is in a HIGH alarm state
when the detected concentration is higher than the set concentration value. Before
leaving the factory, the alarm value has been set. Please check the default settings to
ensure they meet your local or preferred exposure alarm levels.
• The LOW alarm, corresponds to the first set of relay output (COM1 NO1, NC1)
on the detector main board.
• The HIGH alarm, the second set of relay output (COM2, NO2, NC2)
corresponds to the detector main board.
• The Relay (30VDC 2A/220VAC 2A) COM and NO are normally open, COM and
NC are normally closed.
5.4. Gas Zero
Sometimes the gas sensor drifts due to electronics and sensor degradation.
Sometimes, the sensor does not return back to its ZERO baseline. Also sometimes, the
sensor is exposed to HIGH concentrations of toxic gas and the sensor may be
permanently “poisoned”. Please ensure fresh air is exposed to the sensor for at least
30 minutes, before making this determination. If the zero drift of the sensor is
unacceptable, the user can perform a ZERO calibration operation. Pass pure nitrogen
or clean air for at least 2 minutes through the sensor. Click on the “3. Gas Zero” menu.
Enter into the menu items by selecting your gas then press SAVE after exposure to
fresh air or pure nitrogen and a stable reading has been achieved. Please note, if you
have a OXYGEN or CARBON DIOXIDE sensor, you will need to use Pure Nitrogen to
achieve a ZERO Calibration. Other toxic gases will suffice by exposing the detector to
fresh air.
5.5. Gas Check / SPAN CALIBRATION
Only perform calibration is you are an experience technician. Otherwise please contact
the manufacturer for instructions. We have special calibration cap fittings to
undertake precise calibration with (in/out) tube ports.
5.6. AlarmData
The detector can save 1000 alarm records. The interface can view the maximum
alarm concentration in the environment recorded in the "detection interface", as well
as the time point and alarm state of the highest concentration.

5.7. Time Set
The detector has a back-up battery, edit precise time to save. The detector will remain
in accurate operation after the power is turned off.
6. INSTALLATION GUIDE
6.1 Installation Location Considerations
Installing this industrial gas detector will depend on the application. For isolated rooms,
ensure the detector is located at head level to allow for visual inspection of the display
screen. Locate away from ducts and vents, air turbulence (i.e. doors that may dilute air
quality in the room) and in a location that represents the “general” target area air
quality. Some gas (depending if they are light of heavy) may be best mounted very high
on the ceiling or low closer to the ground. Email us for a recommendation.
• Do not install in areas where the temperature is close to detector extreme
specifications for example in very cold or very hot environment 0-122F.
• Do not install within 5 ft. of heating or cooking appliances.
• Do not install near vents, flues, chimneys or air ventilation openings.
• Do not install near ceiling fans, doors, windows or areas directly exposed to the
weather so external air, water or rain reaches the detector.
• Do not install in dead air spaces, such as peaks of vaulted ceilings or gabled roofs,
where toxic air may not reach the sensor in time to provide early warning.
• Do not install on a switched or dimmer-controlled outlet.
• Do not obstruct the vents located on the alarm. Do not place the alarm where
drapes, furniture or other objects block the flow of air to the vents or limit the visual
and audible alarms.
6.2 Detector Installation
The detector is designed to be wall mounted. Depending on local code, conduit for
power wires / RELAY lines may be required, so please ensure a qualified electrical
technician undertakes the installation. The below figure shows a typical conduit
installation. Most installation are custom installations, hence please install detectors
using qualified technical personnel.

** WARNING**
Ø KEEP DETECTOR AWAY FROM ELECTROMAGNETC & MAGNETIC
INTERFERENCES (i.e. PHONES & MAGNETS)
Ø STORE DETECTOR WITHIN SPECIFICATIONS
Ø IF UNWELL, SEEK CLEAN AIR & MEDICAL HELP
Ø ENSURE QUALIFIED PERSONNEL INSTALLS THE UNIT
Ø KEEP AWAY FROM DUST & PARTICULATE AND NEVER EXPOSE TO
EXHAUST GAS or CONCENTRATED VAPORS, HARSH CHEMICALS OR
EXTREMELY HIGH CONCENTRATION LEVELS AS IT MAY POISON THE
SENSOR (SEE APPENDIX FOR RANGES)
Ø FOLLOW INSTRUCTIONS AS THE DETECTOR IS VERY SENSITIVE
Ø Connect the cable according to the Ex request. The end of the cable
need to be treated properly and should be connected to Ex junction box
or equipment. When the detector doesn’t need to work with the
controller, the block is not allowed to take off the cable entrance and
the block have to be kept in the cable entrance closed with the seal
ring.
Ø Don’t open the cover when the power is on.
Ø Pay attention to not break the Ex surface.
