B. INSTALLATION
B.1. DOCUMENTS REQUIRED FOR INSTALLATION
These instructions.
Instructions relating to installed CIE (Control and Indicating Equipment) fire alarm panel.
B.2. SPECIFIC INSTALLATION TOOLS
In addition to ordinary electrician tooling, the following is needed:
– A stop watch ;
– A flat 3 mm screwdriver ;
– 3 round head fastening screws, ∅= 4 mm, 30 mm length ;
– A voltmeter with male plug cords ∅= 4 mm (voltage ≤5 Vdc) ;
– The black colour mask taken from the packaging box ;
– A piece of packaging type brown cardboard that covers the whole surface area of the reflector ;
– If the detector should integrate an addressable SDI, a BT95C or BT05C coding bench.
Note: the use of the DETTEL replaces the use of the voltmeter and of the coding bench
B.3. PRODUCT IDENTIFICATION
Whatever the nature of the installation to be done, the product should be identified with a label showing:
•Either the N°of the detection area for a conventional system,
•Or the address of the point and N°of detection area for an addressable system.
Note: Prior to any use of a detector linked to an SDI made from an addressable CIE, the latter should be
addressed using the BT95C or BT05C coding bench, or through the DETTEL.
B.4. INSTALLATION RULES
B.4.1. General installation rules
The installation should be done in accordance with national installation rules.
Provide access to the detector and to the reflector for the start up and maintenance operation.
Ensure that the Indicator light can be seen.
B.4.2. Mechanical installation rules
The « T/R » part is installed vertically on a stable wall. Such stability should take into account the
following parameters:
•Flat fastening partition. Otherwise, use an intermediate mounting (for instance, marine plywood,
20 mm thick)
•Building stability (excluding unstable partitions, siding, etc)
•Whether environment (no mounting that moves under the influence of temperature or wind, no
condensation, etc).
The reflector should be mounted on a stable wall free from vibration, opposite the « T/R » part.
B.4.3. Optical installation rules
Do not expose the detector or its reflector to direct sunlight. In the event of momentary parasitic sun
reflections or scattering, the use of an external diaphragm on the Receiver of the « T/R » part and of
sunshield on the reflector can allow for stable operation (See § F). The number of «MIR10» should then
be adapted (See § G).
No part should cut the detector beam permanently or temporarily (conveyor for instance).
For the beam passage, allow for an entirely empty circle with a minimum diameter of 1 m in order to
ensure the operation of the product.

C. START UP OF DLFBe
C.1. INTRODUCTION
C.1.1. Handling the push buttons
The detector has 4 buttons respectively marked from « A » to « D » ; each valid press on one of the
buttons is confirmed by the turning on of the green indicator light or turning off if it was on.
During the start up phase, the « C » button is used to put the detector back in its initial condition or on
standby.
The « D » push button is not used.
C.1.2. Turning on
Turn on the detector:
– Either by referring to the CIE start up instructions
– Or by connecting an external 24 V supply in continuous current limited to 0.1 A by the detector.
When turning on the indicator light is yellow and blinking. That initialisation phase lasts about 20 sec.
If during the detector setting phases described below, any of the expected results cannot be achieved, it
is essential to:
•Turn the detector off for at least 1 minute
•Resume the procedure in the « Calibration » paragraph after initialisation.
Note: After turning on the « T/R » part, if the light comes on red and steady (with or without a flash) this
means that the detector did not initialise itself property. In that event, disconnect all supplies for about one
minute and try turning on again.
C.1.3. Code setting
Depending on use conditions, it is possible to adjust a number of parameters of the detector such as
alarm sensitivity, fault filtering, etc (See § D.1)
C.2. DLFBe CALIBRATION
The calibration consists in aligning accurately the « T/R » part on the reflector.
The setting procedure is as follows:
1. Switch to Normal Calibration Mode by pressing the « A » key twice at a one second interval ;
2. Using the horizontal and vertical setting wheels, roughly orient the detector opposite the reflector so
the light spot produced by the transmitter is focused on the reflector ;
Following those operations, there can be 4 cases:
Case Signalling Interpretation
1
the yellow indicator light blinks +
flash dazzling, too much parasitic light (sun for instance) (See § B.4.3 and F.1 for use of optical accessories)
2
the red indicator light blinks Too much reflected signal: reflector is over dimensioned or interfering reflecting
surface.
3
the green indicator light is on Correct.
4
the yellow indicator light blinks Not enough reflected signal: reflector is undersized, misalignment
Caution: only case 3 is acceptable and allows to continue the detector setting ; the other cases should be
solved before going on.
3. Connect a voltmeter to the test (A and B) output located over the
« T/R » part (See Figure 10) ;
Figure 10: Test output locating
4. Switch to Fine Calibration Mode by pressing the « A » key ;
5. Wait until the yellow blinking light signal comes on ;
6. Set the detector horizontally and vertically using the two wheels in
order to increase the voltage value on the voltmeter. Over a 2.6 V
voltage, the receiver is saturated ;
7. Switch to Normal Calibration Mode by pressing the « A » key ;

8. Wait until the steady green light signal comes on ;
9. Repeat steps 4 to 9 as long as the voltage can be increased on the voltmeter ;
10. Exit the Calibration Mode (Normal or Fine) by pressing the « C » key ;
11. Wait for about 30 sec for the detector to exit the Calibration Mode. A proper exit of the Calibration
Mode is shown by the green light coming on for 3 sec. An improper exit of the Calibration Mode is
shown by the steady yellow light and superimposed flash. In that case, resume the setting procedure
from point 1.
Note 1: During the waiting times, do not move the detector and do not cut the beam.
Note 2: Start the calibration over if the procedure is not entirely complied with.
Note 3: In Calibration Mode, each pressing on the « A » key allows alternatively to switch from Normal
Calibration Mode to Fine Calibration Mode. The values read on the voltmeter cannot be used for
alignment other than in the Fine Calibration Mode.
C.3. CALIBRATION CHECK
Three tests are vitally required to check that the calibration has been completed properly.
If one of the following tests is not successful, carry out a new calibration.
C.3.1. Target test
This test allows to check:
– That no interfering reflection disturbs the proper operation of the detector ;
– That the targeted target is the proper one.
The test procedure is as follows:
Enter the Target Test Mode by pressing successively the « A » button, then the « B » button after a
one second interval ; the indicator light comes on red and blinks
Cover the whole surface of the reflector with a non reflecting object (See B.2) ;
Display the indicator light of the « T/R » part. Refer to the table below for the interpretation of the
indicator light ;
Signalling Meaning
steady green light Acceptable level of reflection
blinking red light Too many interfering reflections (See Note below)
Exit the Target Test Mode by pressing the « C » button or resetting the CIE.
Note: With the reflector still covered, look for the reflecting object or objects along the beam by covering
them, so as to achieve a green light signal. Following those investigations, 2 options are possible:
•Either cover permanently the disturbing object or objects,
•Or move the detector.
C.3.2. Fault test
That test allows to check that the detector switches properly in fault when the beam is cut.
The test procedure is as follows:
The detector has been on standby for at least 1 minute ;
Place a black cover (See § B.2) in front of the two lenses of the « T/R » part for at least 60 sec ;
At the end of that time, the indicator light switches to steady yellow + superimposed flash to show the
fault condition ;
Remove the black cover.
The fault condition is not memorised by the CIE, and that signal disappears after a maximum time of
80 sec.

C.3.3. Fire alarm test
That test allows to check that the detector switches properly to fire alarm with the use of the fire alarm
simulation filter
The test procedure is as follows:
The detector has been on standby for at least 1 min ;
Place the fire alarm filter provided in the package right before the
2 lenses of the detector for at least 30 sec (See Figure 11) ;
After that time, the indicator light switches to steady red + superimposed
flash to show the fire alarm condition ;
Remove the fire alarm filter ;
Reset the CIE.
Note

:
That test in no way replaces real and regulatory tests.
Note

:
Take all required precautions not to trigger an unwanted evacuation
or start off the actuators.

D. ADVANCED SETTING
D.1. FUNCTIONAL PARAMETERS
The table below lists the level 2 “button codes” for the setting of the DLFBe.
To change one of the parameters, the procedure is as follows:
•At one second intervals, press the buttons to dial the desired code ; each pressing is confirmed by a
green flash emitted by the indicator light ;
•When the code is property entered, the signal emitted by the indicator light is the one mentioned in
the « validation » column ;
•To exit the programming at any time, press the « C » key.
The sequence of 3 green, yellow and red pulses means either:
– That the entry is wrong ;
– The entering time is exceeded ;
– The requested setting is not accepted.
In all cases, the detector switches back to normal operation without changing the setting.
Note: In the event of a power cut on the detector, it keeps the last parameters that were entered.

Note (1): This setting only concern the relay version.
Note (2): These settings are not compatibles with the NF mark requirements.
Note (3): Automatic resetting of the alarm after the time indicated when the alarm cause is no longer
detected.
Note (4): In Relay version, the default power of the calibration beam is high. In all other versions, the
default power is low. In conventional, the use of the configuration may switch the connected CIE to alarm.
Note (5): The default parameter (« works setting ») depends on the version that is marketed.
Note (6): The key is activated by default
D.2. VISUALISATION OF ACTIVE CONFIGURATION
To note the current configuration, the procedure is as follows:
At one second interval, press the keys to dial the code « CB BBBB »
Note the sequence of green and red pulses and compare it with the table below.
Note 1: Each sequence starts with a green pulse.
Note 2: The number of red pulses that follows a green pulse provides the status of the configuration in
the sequence.

Note (3): This configuration is pointless other than for the relay version
Note 4: The use of the DETTEL allows to read the active configuration textually.
D.3. FIRE ALARM EMULATION
This test allows to put the linear smoke detector in fire alarm condition, without sending the alarm to the
CIE.
The test procedure is as follows:
•At one second intervals, press the push buttons to dial the « CB BABB » code to activate the fire
alarm emulation
•After 3 seconds of measuring the indicator light comes on for 10 sec:
In steady red + superimposed flash in case of success
In steady yellow + superimposed flash in case of fault
That test is automatically exited in less than 30 sec.
Note 1: That fire alarm emulation cannot be triggered if the distance between the optical block and the
reflector is less than 15 m. In that case, an error signal is immediately sent for 10 sec.
Note 2: That fire alarm emulation does not replace real and regulatory fire tests.

D.4. FAULT EMULATION
This test is used to put the linear smoke detector in fault condition, without however sending such fault to
the CIE.
The test procedure is as follows:
•At one second intervals, press the buttons to dial the « CB BABA » code to activate the fault
emulation
•After 3 sec of measuring the indicator light
Comes on for 10 sec in steady yellow + superimposed flash, in case of success
Does not come on in case of fault
That test is automatically exited in less than 30 sec.
D.5. RELAY CONTACT SETTING
By default, the position of the contacts for the DLFBe Relay version is:
•« NC » for the fault. The contact of the fault relay is « NC » (Normally Closed) in standby condition. In
fault condition, the relay is not active (« NO » contact)
•« NO » for the alarm. The contact of the alarm relay is « NO » (Normally Open) in standby condition.
In alarm condition, the relay is active (« NC » contact).
Note: If the DLFBe relay version is not supplied the fault relay contact is open
It is possible to set the relay contacts using one of the 2 switches located behind the optical block. The
procedure for accessing the switches is as follows:
Remove the cover (See Figure 7)
Unscrew the vertical setting wheel nut without removing it from the screw
Remove the screw from the vertical rotation axis
Remove the optical block from its accommodation
Unclip the holding clip from the top of the optical block and from the optical block back. To do so
press with the 2 thumbs towards the bottom and slip them to the front to release the holding clip (See
Figure 12)
Figure 12: Procedure for access to the 2 switches Figure 13: Drawing of the 2 switches allowing to set the
contacts to alarm and fault relay
After the setting of the relay contacts using 2 switches, reassemble the detector by following these steps:
Assemble the optical block back with the optical block by clipping the upper holding clip in its
accommodation
Insert the optical block in its accommodation
Insert the vertical rotation axis screw in its spot. Screw it in the square nut without tightening
Screw the nut of the vertical setting wheel until the optical block is straight in relationship to the base
plane. Check that the nut is well placed in its spot
Put the cover back.

F. INSTALLATION OF OPTICAL ACCESSORIES
F.1. EXTERNAL DIAPHRAGM
Refer to § B.4.3 prior to using the external diaphragm.
In case the detector is used in a highly intense environment, it is necessary to use the external diaphragm
that reduces the dazzle phenomenon.
If the detector is dazzled in operating mode, it switches to fault. The detector returns to its standby
condition after the dazzle disappears.
Positioning of external diaphragm:
•Position the external diaphragm in front of the receiving lens (optics of top of product) (See Figure 14)
•Orient the diaphragm so the engraved triangle is towards the top (See Figure 15)
•Push the diaphragm into the receiving spot until a clip sound is heard.
Note 1: After installing the diaphragm, the detector should be calibrated again
Note 2: To remove the external diaphragm from its spot, pull it to the back from on top
Figure 14: Diaphragm placed in front of the Receiver
of the optical block. Figure 15: External diaphragm with its engraved triangle
The use of the external diaphragm can include an increase in the reflector surface area (See § G).
F.2. SUNSHIELD
Refer to § B.4.3 before using the sunshields.
Application conditions:
The sunshield on the reflector (See Figure 16) protect the
detection system in the event the angle between the interfering
light rays and the optical axis of the reflector (axis perpendicular
to the reflecting side of the reflector) is over 40°.
It is possible to superimpose 2 sunshields. Such an assembling
protects the detection system in the event the angle
between the
interfering light rays and the optical axis of the reflector ranges
from 20°to 40°.
Figure 16: Sunshield
Note 1: When there are 2 layers of sunshields, it is vital to place the optical block on the optical axis of
the reflector.
Note 2: If the interfering sun rays reach the section of the reflector, it should be protected by matt black
film.
Fastening the sunshields:
A sunshield is fastened on a reflector using clips. When using a reflector made up of several reflectors,
mount the sunshields on the reflectors before assembling the whole unit.
To assemble several items, orient the sunshields to reduce the space between 2 reflectors (See
Figure 17 and Figure 18).

INSTALLATION AND STARTING UP SHEET
This sheet describes the main steps to be completed to install and start up the detector
1 Estimate the distance between the detector and the reflector
2 Is the detector exposed to direct sunlight (See B.4.3) ?
If Yes, change the intended location of the detector
3 Is the reflector exposed to directly sunlight (See B.4.3) ?
If Yes, change the intended location of the detector
4 Is the luminous environment (diffusion of natural light, interfering reflexions …)
very intense ?
If Yes, use the optical accessories
5 Determine the number of MIR10s to be installed based on
the answers to steps 1 and 4 (See G)
6 In the event optical accessories are used, clip the sunshields
to the MIR10 (See F.2) before assembling them
7 Is the space requirement of the detector for its installation
compatible with the intended location (See B.5.1) ?
If No, change the intended location of the detector
8 Is the space requirement of the detector compatible with the intended location (See B.5.2) ?
If No, change the intended location of the detector
9 Install the detector (See B.6.1) according to mechanical installation rules (See B.4.2)
10 Install the reflector (See B.6.2) according to mechanical installation rules (See B.4.2)
11 Complete the electrical connection of the detector (See B.7)
12 Turn on the detector (See C.1.2)
The DETTEL supplies the detector in the event the ECS is not connected (use of the DETTEL)
13 Carry out the calibration of the detector (See C.2)
Is the calibration exit correct ?
If No, do the calibration again
14 Note the recorded gain value and check that it is under 200. If not, resume the installation
from step 13 (use of DETTEL)
15 If optical accessories are used (See B.4.3), clip the external diaphragm
to the receiving lens (upper lens) of the detector (See F.1). In that case,
calibrate the detector again
16 Perform a target test (See C.3.1)
Is the visual indicator green when the whole reflector surface covered ?
If No, check that the detector is indeed aligned on the reflector (resume the installation
from step 13 as needed) and check that there is no interfering reflexion
on the beam route (cable tray, metal beams…)
17 Perform a fire alarm test using the alarm filter provided in the packaging (See C.3.3)
Is the detector switched to fire alarm after the specified time ?
If No, resume the installation from step 13
18 Reset the ECS or the detector (case of Relay version) to clear the fire alarm condition.
19 Set the time on the detector (use of the DETTEL)
20 Delete the history (use of the DETTEL)
