Warnings
WARNING - Through engineering design, testing, manufacturing techniques, and
rigid quality control, General Monitors supplies the finest flame detection systems
available. The user must recognize his responsibility for maintaining the flame
detection system in operational condition.
WARNING - The Model FL3102 DFIR Flame detector contains components,
which can be damaged by static electricity. Special care must be taken when
wiring the system, to ensure that only the connection points are touched.
SAFETY WARNING - Installation and Maintenance must be carried out by
suitably skilled and competent personnel only.
TOXIC, COMBUSTIBLE AND FLAMMABLE GASES & VAPORS ARE VERY
DANGEROUS. EXTREME CAUTION SHOULD BE USED WHEN THESE
HAZARDS ARE PRESENT.

System Integrity Verification
General Monitors mission is to benefit society by providing solutions through
industry leading safety products, services and systems that save lives and
protect capital resources from the dangers of hazardous flames, gases and
vapors.
The safety products you have purchased should be handled carefully and
installed, calibrated and maintained in accordance with the respective product
instruction manual. Remember these products are for your safety.
To ensure operation at optimum performance, General Monitors recommends
that certain maintenance items be performed.
Commissioning Safety Systems
Before power up, verify wiring, terminal connections and stability of mounting for
all integral safety equipment including, but not limited to:
•Power supplies
•Control modules
•Field detection devices
•Signaling / output devices
•Accessories connected to field and signaling devices
After the initial application of power (and any factory specified warm-up period) to
the safety system, verify that all signal outputs, to and from devices and modules,
are within the manufacturers’ specifications. Initial testing should be performed
per the manufacturers’ recommendations and instructions.
Proper system operation should be verified by performing a full, functional test of
all component devices of the safety system, ensuring that the proper levels of
alarming occur.
Fault/Malfunction circuit operation should be verified.
Periodic Testing of Field Devices
Periodic testing/calibrating should be performed per the manufacturers’
recommendations and instructions. Testing/Calibrating procedures should
include, but not be limited to:
•Verify integrity of all optical surfaces and devices
•For flame detectors, use the appropriate test lamp
When testing produces results outside of the manufacturers’ specifications,
replacement of the suspect device(s) should be performed as necessary.
Maintenance intervals should be independently established through a
documented procedure, including a Maintenance log maintained by plant
personnel or third party testing services.

Periodic System Verification
The following system verifications should be performed at least annually:
Verify wiring, terminal connections and stability of mounting for all integral safety
equipment including, but not limited to:
•Power supplies
•Control modules
•Field detection devices
•Signaling / output devices
•Accessories connected to field and signaling devices
Proper system operation should be verified by performing a full, functional test of
all component devices of the detection system, ensuring that the proper levels of
alarming occur.
Fault/Malfunction circuit operation should be verified.
Maintenance intervals should be independently established through a
documented procedure, including a maintenance log maintained by plant
personnel or third party testing services.

1.0 Quick Start Guide
1.1 Upon Receipt of Equipment
All items shipped by General Monitors are packed in shock absorbing containers,
which provide a considerable degree of protection against physical damage.
When received, the contents should be carefully removed and checked against
the enclosed packing slip. All subsequent correspondence with General Monitors
must specify the equipment part number and serial number.
1.2 Choosing Detector Locations
Several variables are involved in selecting the locations to install detectors to
ensure proper flame detection. There are no hard and fast rules defining the
optimum location. There are some general suggestions that should be
considered in regard to particular conditions at the site where the unit(s) are
being installed:
1.2.1 Detector Field of View
Each Model FL3102 Flame Detector has a 120° maximum Cone of Vision. This
Cone has its vertex at the center of the detector (see Figure 1).
1.2.2 Optical Sensitivity Range
The distance at which the detector will respond to a flame is a function of the
intensity of that flame. The maximum distance is 50 feet (15.2m) for a gasoline
fire with a surface area of 1 square foot (0.92m2).
1.2.3 Environmental Factors
•Mounting should be as free from shock and vibration as possible and
convenient for visual inspection and cleaning.
•Detectors mounted in dirty atmospheric conditions will require more frequent
inspection, cleaning, and sensitivity checking.
•Observe the ambient temperature range for the specific model (see Section
8.1.4 Environmental Specifications). For outdoor installations or other areas
exposed to intense, direct solar radiation, the detector may reach
temperatures well above specifications. For this condition, a cover for shade
may be required to bring the detector temperature within specifications. As
with any cover or object near-by, make sure the field-of-view of the detector
is not obstructed.
•Avoid conditions of ice build up on the optical detector windows. Complete
icing-over of the IR detector window can result in fault conditions.

1.3 Detector Installation
The Model FL3102 Detector is an explosion proof assembly rated for use in
Class I, Divisions 1 & 2, Group B, C & D, Class II, Group E, F & G, and
Class III areas. The detector(s) should be mounted pointing downward so that
dust/moisture will not accumulate on the IR windows. The detector(s) should be
mounted in locations, which will inhibit people or objects from obscuring the
detector’s Cone of Vision.
NOTE – Before installing these units, please read the warning statement on page
13 of this manual. These units must have a conduit seal installed.
Mounting hardware should be used as shown in Figures 2 and 3.
NOTE – The swivel (961-003) is rated for Class I, Div 1 & 2, Groups C & D. Use
mounting bracket for Group B areas.
The overall dimensions of the detectors and mounting hardware are shown in
Figure 4.

WARNING – General Monitors requires that the conduit entry be sealed per the
Canadian Electrical Code Handbook (Part 1, Section 18-154). Conduit seals
prevent water from entering the units’ housing through the conduit entry. Water
entering the housing through the conduit entry will damage the electronics and
nullify the warranty.

1.4 Terminal Connections
All wire connections are made through the ¾ NPT openings in the Base
Assembly to the terminal block (See Figure 7). The Terminal Block is located on
the Base Assembly (See Figure 8) and accepts 12 AWG to 22 AWG stranded or
solid-core wire. Each wire should be stripped as shown in Figure 5.
Figure 5 Wire-Strip Length
To connect the wire to the Terminal Block, insert the conductor into the
connection space as shown in Figure 7 and tighten the corresponding screw
terminal.
