A.1. INTRODUCTION
The linear optical smoke detector consists of two parts positioned one in front of the other:
– An “Emitter/Receiver” part (E / R),
– A reflector consisting of 1 safety reflector.
A.2. USAGE LIMITS
The linear smoke detector cannot be installed inside buildings.
OPTICAL BLOCK
1 fastener screws
2 built-in laser pointer
3 button
4 terminal connector
5 indicator light
SPECIAL EQUIPMENT
In addition to the normal tools supplied, the following is required:
– A piece of brown cardboard (packaging type) which can cover the whole surface of the reflector (minimum 10 cm
x 10 cm).
INSTALLATION RULES
A.2.1. General rules
Installation must be carried out in compliance with national installation regulations.
Make sure both the detector and reflector can be accessed for commissioning and maintenance procedures.
A.2.2. Rules for the installation site
The E / R and the reflector are installed vertically, one in front of the other, on a stable wall; this stability must take
account of the following parameters:
Smooth fixing wall; if it is uneven, use an intermediate support (for example, a 20 mm thick plywood plate).
The building must be stable (exclude unstable walls, cladding, etc.).
Ambient climatic conditions (for supports which could move in the event of wind, temperature changes,
condensation, etc.).
A.2.3. Optical rules
Do not expose the E / R and reflector to direct sunlight.
To accommodate the detector beam, provide a completely free circular area with a diameter of at least 60 cm; this is
necessary to ensure the product works properly.

INSTALLATION OF THE ELEMENTS
The main detector installation steps are as follows:
Step Step description
1
Securing the detector base
2
Electrical connections
3 Securing the optical block
4
Activating the laser pointer (press button)
5
Securing the reflector
6 Deactivating the laser pointer (press button)
Caution:
Leave a free area of at least 30 cm around each element installed on the wall.
A.2.4. Flush-mounted base
The flush-mounted base is dedicated to
recessing the E / R in a wall or dividing
wall.
The text on the base
helps you position it
correctly on the wall.
A.2.5. Surface-mounted base
The text on the base
(reference 3) helps
you position it
correctly on the wall.

A.2.6. Laser pointer
During installation, the reflector is positioned with the help of the laser pointer built into the E / R.
This pointing function is independent and does not require an external power supply.
To activate the laser pointer: press the button and hold for more than a second, then release.
To deactivate the laser pointer: press the button again. If the button is not pressed, it will deactivate automatically after
20 minutes.
A.2.7. Securing the reflector
Once the zone indicated by the laser pointer has been identified, deactivate the pointer or block the laser beam to
prevent it from reflecting into the eyes of the installer while it is fixed in place.
Caution:
The smooth surface of the safety reflector must be directed outwards.
Switch off the pointer as soon as you have identified the point indicated by the laser beam.
The reflector is secured in 2 steps:
Step 1: securing the safety reflector support.
Use screws with a maximum diameter of 4 mm to secure
the safety reflector support to the wall.
Step 2: safety reflector coupling.
The smooth surface of the safety reflector must be directed
outwards (i.e. towards the E / R).
A.2.8 Securing the E / R part
After the electrical connections have been carried out on the 9- and 10-pole terminals, fit these terminals in the
corresponding positions on the back of the E / R.
Encoding on the base (ref. 10 in the nomenclature) allows correct positioning when fixing the E / R part to the base.
A.3. ELECTRICAL CONNECTIONS
Once the base has been fixed to the wall, carry out the electrical connections; make sure you use a power supply
which conforms to the electrical specifications contained in this manual.
For information regarding electrical connections, please refer to the table below and the installation sheet at the end of
this document.

1. If the detector enters fault status, the relay contact opens.
2. For connection of the remote box, unshielded 2 x 2 x 0.5 mm2 cables are recommended, for COM+/COM- and
TL+/TL- respectively. The K+ terminal is connected by means of a wire from a 2 x 0.5 mm2 cable.
COMMISSIONING
A.4. MAIN STEPS
Commissioning takes place by means of the following steps:
Step Step description
7 Powering up the E / R part
8 Activating the laser pointer (press the button)
9 Deactivating the laser pointer (press the button)
10 Automatic calibration startup (1)
11 Alignment check startup (2)
12 Reflector masking
13 Alignment check completion
14 Alarm check
1. This function starts up automatically when the laser pointer is deactivated.
2. This function starts up automatically following a successful automatic calibration.
A.5. POWERING UP
Power up the E / R after making sure the power supply provided is compatible with the specifications of the detector;
please refer to this document and the manual for the detector control panel or the 24 Vdc power supply unit, with the
output limited to 100 mA per detector.
Every time it is powered up, the detector enters an initialising phase lasting 10 seconds; the end of this phase is
indicated by the light-up indicator on the front flashing green.

A.6. LASER POINTER
During commissioning, activation of the laser pointer makes it possible to check that the reflector has been positioned
correctly in relation to the E / R.
If the zone indicated by the laser beam is more than 5 cm away from the reflector, adjust the position of the E / R,
using the corresponding screws to bring the point indicated by the beam closer to the reflector.
To activate the laser pointer: press the button and hold for more than a second, then release.
To deactivate the laser pointer: press the button again. If the button is not pressed, it will deactivate automatically after
a delay of 20 minutes.
A.7. AUTOMATIC CALIBRATION
Automatic calibration consists of defining and storing the parameters inside the detector, based on:
The distance between the E / R and the reflector,
The position of the reflector in relation to the E / R.
Automatic calibration starts automatically when the laser pointer is deactivated after the button is pressed; the
automatic calibration sequence is as follows:
During automatic calibration the barrier may trigger the alarm for the conventional zone to which it is
connected if it is powered from that zone.
Indicator light Step description
Flashing green Automatic calibration in progress
Steady green Automatic calibration performed correctly
Flashing orange Automatic calibration error (1)
1. In this case, start a new automatic calibration process by pressing the button; take care not to block the infrared
beam.
Note: If the orange light flashes when you start the automatic calibration process (when you press the button to
deactivate the laser pointer), make sure the detector and reflector are not exposed to direct sunlight.
Note: If the orange light flashes after a succession of green pulses, carry out E / R alignment again so that the point
indicated by the laser beam is on the reflector.
A.8. ALIGNMENT CHECK
This check allows you to make sure there are no parasitic reflections which could compromise detector operation.
The detector automatically enters alignment check mode after an automatic calibration procedure has been carried
out successfully. In this case:
1. The indicator light flashes red,
2. Completely mask the surface of the reflector with a non-reflective object (packaging cardboard, for example) for at
least 10 seconds,
3. While the masking is in place, the indicator light may assume one of the two following statuses:
Indicator light Meaning
Steady green Acceptable reflection level
Flashing red Excessive parasitic reflection level (see note)
4. Exit alignment check mode by pressing the button or by restarting the control panel.
Note: While the reflector is masked, it is wise to search for reflective objects along the route of the infrared beam and
cover them in order to obtain the green indication. After this search, there are two alternative solutions:
Cover the reflective objects permanently,
Move the detector.
Caution:
Take all necessary precautions to avoid activating the evacuation process or ordering activations
accidentally.
This check does not in any way replace actual standardised tests, but can be used during servicing test
procedures.
Note: If the indicator light does not turn red to indicate an alarm within 40 seconds, disconnect the detector from the
power supply for 2 minutes and repeat the commissioning procedures.
