1 Introduction
The TBD-8100 Beam Detector is comprised of an optical transmitter and a receiver
within the same device.
The transmitter sends out an invisible infrared beam, which is reflected by a prism
mirror; the mirror is placed on the opposite wall, facing the transmitter in a manner that
nothing blocks the beam’s path from one side to the other. The optical receiver monitors
the intensity of the reflected beam.
The detector can detect up to 9 meters on each side, 18 meters altogether.
The TDB-8100 detectors can be installed at three distance ranges:
8 to 50 meters (one prism)
50 to 75 meters (two prisms)
75 to 100 meters (four prisms)
2 Compatibility
The TBD-8100 is compatible with the following control panels:
All TSA-1000 models and TSA-1000X
TSA-200, TSA-240, TSA-200XT, TSA-240 XT, and TSA-200X

3.1.3 Cabling Planning –24Vdc Supply
The module requires 24Vdc from the addressable control panel or an auxiliary power
supply such as the TPS-74A OR TPS-34A.
Use an auxiliary power supply whenever the module is installed a long distance from the
addressable control panel or whenever the total current consumption of all NACs
exceeds the capability of the addressable control panel's 24Vdc output.
3.1.4 Cabling planning –shielded cables
It is recommended to avoid wiring outside buildings due to a risk of lightning strikes. If
required, it is mandatory to use shielded cables. The shielding must be grounded via the
control panel grounding terminals.
3.2 Installation –Prior to Detector Positioning
3.2.1 Control Panel Detector Configuration –Addressable Control
Panels
Configure the input addresses of the ADR-712, ADR-718, or ADR-812A as Input Circuit.
Please refer to the control panel’s technical instructions for further details concerning
device programming.
3.2.2 Input configuration in a control panel (TSA-1000 only)
Ensure that the input, to which the detector is connected, is configured at the panel as a
type D input (regular detectors zone). Please refer to the TSA-1000 technical manual for
a detailed explanation concerning the mode of configuring the various types of inputs.
3.3 Installation –Placing the Detector
The TBD-8100 is designed to protect indoor fire risk areas, except environments where
smoke, steam, dust, or corrosive gasses are present under normal conditions.
Observe NFPA 72 guidelines and local fire codes when installing the detectors.

In order to decrease detection time, a proper positioning of the detector is most
important.
Based on experience, it is well known that smoke rising from a fire does not go straight
upwards, but tends to flow sideways; as a result of air flows and the effect of
temperature gradients among the various air layers, the smoke creates a "mushroom"
shape at a certain elevation.
The time interval between the actual time that the fire started and the time that the
smoke detector alarm sets off depends upon the location and elevation of the beam
detector, the detection zone, the amount of smoke emitted, the ceiling's shape and the
ventilation.
The detection coverage on each side of the beam is 9 meters maximum. Place the
detector up to 9 meters from the wall, or 18 meters from the next, similar, parallel
detector, under a flat ceiling.
i
Note
Install the detector horizontally with the red light down on the right side.
Figure 1 Placing the Detectors
Commonly, rising smoke tends to spread sideways before it reaches the ceiling because
a layer of hot air near the ceiling prevents the smoke’s further rise. Therefore, the
detector should be installed on the building’s wall, at least 50 cm but no more than 1
meter below the ceiling in order to comply with the UL 268 / NFPA 72 and the SI 1220-3
2014 edition.
i
Note
Measure the wiring to ensure there are no shorts before connecting the wiring
to the control panel.
Connecting or adding inputs, outputs, and extinguishing devices shall be
done when all power to the control power is disconnected (AC and batteries
disconnected).

assembly input using a model TRA-1B adapter
3.3.2 Connection of an Optional TBD-8100R Indicator Module
Position the TBD-8100R assembly at eye level.
The TBD-8100R assembly is intended for receiving alarm or fault warnings from the
detector.

The assembly also enables checking the detector’s functioning: If a magnet is positioned
near the indicator’s LED indication light, the detector enters an alarm mode.
Additionally, using the TBD-8100C instrument of the TBD-8100R assembly, you can
assess the detector’s signal strength, amplification and type of fault (the letter F appears
in one of the screen’s locations):
a. More than 50% dust accumulation on the detector
b. More than 90% dust accumulation on the detector
c. Signal level is very low or it does not exist
d. Alarm
The most recent alarm of the detector (in case there are several detectors connected
within the same zone).

Note
In some cases (usually when the distance between the detector and the
prism is less than 10 m), there is a need to attach the black patch, supplied
with the detector, onto the transmitter’s lenses.
The detector would signal during the initial detector direction, by
lighting up the 4 green LEDs, that the black patch must be attached.
3.4.1 Using detector card 4 LEDs or a voltmeter
1. Move the alignment switch (DIP SW 6) to the calibration position (ON).
2. Power on the detector.
3. Slowly turn one of the alignment wheels in one direction while watching the HL1-
HL5 LEDs. As the detector approaches optimum calibration, the number of lit green
LEDs increases from left to right.
Each LED that lights up, indicates that the beam’s signal strength is increasing. You
should aim to reach a maximum number of lit LEDs.
If only the red LED lights up, the beam is not being reflected by the prism.
Additionally, the signal strength can be measured by connecting a voltmeter to
points +RM- in the XT1 adapter.
The voltage should approach the voltage supplied to the detector.
4. If the number of lit LEDs starts decreasing, you are moving away from the optimum
direction –Retract until you reach a maximum number of lit LEDs.
5. Measure the voltage between points 3 and 4 (RM) in the XT1 connector. Maximize
the voltage so that it approaches 24Vdc, as near as possible (at a small operating
range of the detector, when the patch is attached to the lens, the actual voltage
measured during calibration is only about one half of the input voltage).
6. Repeat the procedure with the other wheel.
7. Verify that the detector faces the prism and does not receive reflections from other
sources. Cover the prism and check if the voltmeter’s voltage drops to around 0V.
8. Return calibration switch 6 to the OFF position and you have about 50 seconds to
put back the detector’s cover. After a minute and a half the red LED starts flashing
once every 5 seconds, approximately.
3.4.2 Adjusting the detector using an external monitor
1. Connect a monitor to a TRA-1B adapter at the TV In +/- terminals
2. Power on the monitor
3. Turn the alignment switch (DIP SW 6) to the calibration position (ON)
i
Note
Do not power on the detector before the DIP SW 6 has been switched to the
calibration position (ON).
4. Turn the detector power ON. Attention –During calibration, the detector is in a fault
mode

5. Turn switch 3 to the OFF position. In this position, the detector’s data is displayed
on the monitor
Figure 7 The Monitor’s Display
6. Using the detector’s adjustment wheels, swivel it around the horizontal and vertical
axes until the prism’s image reaches the center of the monitor; then, by fine tuning,
reach a maximum signal strength
In certain cases, the maximum signal strength center might be reached when the
prism is not at the monitor’s center
Additionally, the RM voltage can be measured at points 3(+) and 4(-). The voltage
should approach 24Vdc
7. Slowly turn one of the adjustment wheels in one direction while watching the HL1-
HL5 LEDs. As the detector approaches optimum calibration, the number of lit green
LEDs increases from left to right
i
Note
In some cases (usually when the distance between the detector and the
prism is less than 10 m), there is a need to attach the black patch, supplied
with the detector, onto the transmitter’s lenses
The detector would signal, by lighting up the red led, during the initial
adjustment, that the patch must be attached.
8. If the number of lit LEDs starts decreasing, it means that you are moving away from
the optimum direction –Retract until you reach a maximum number of lit LEDs
9. Measure the voltage between points 3 and 4 (RM) in the XT1 adapter
10. Maximize the voltage so that it approaches 24Vdc, as near as possible (at a small
operating range of the detector, when the patch is attached to the lens, the actual
voltage measured during calibration is only about one half of the input voltage)
11. Repeat the procedure with the other wheel
12. Verify that the detector faces the prism and does not receive reflections from other
sources. Cover the prism and verify that the voltmeter’s voltage drops to around 0V
13. Revert calibration switch 6 to the OFF position, and you have about 50 sec to return
detector’s cover. After a minute and a half, the red LED starts flashing once every
four seconds, approximately

3.5 Testing the Detectors in the Field after Installation
i
Note
Ensure that the control panel is in walk test mode before testing the
detectors.
1. Execute the detector field-test:
2. Cover the prism with a non-transparent material (cardboard)
3. Ensure that the detector does not enter a fault status for a period of 5 seconds, and
after 20 seconds the control panel indicates a fault
4. Verify that the detector’s red LED flashes every 1 second
5. Once the cardboard has been removed from the prism, verify, that the detector
returns to normal operation and the red LED flashes once every 5 seconds
6. Cover 70% of the prism, and induce an alarm
This action can also be carried out by bringing a magnet near the display LED in the
optional TBD-8100R module, provided the LED is connected to the detector
7. Ensure that the detector is programmed in the appropriate matrices as specified by
the planning consultant.
