DETERMINE THE POSITIONS OF THE IMAGER AND REFLECTOR
COMPONENTS
Make sure that the intended mounting locations meet the following criteria
(See Figure 2.):
• Detector spacing must comply with local codes and standards
• Reflector must be located within the Field of View (FOV) of the Imager
• Clear path between the reflector and Imager
• Mounted well above the head-height of people and obstructions
• Avoid direct sunlight onto the units
The Imager and reflector should be placed within a recommended distance
below the ceiling. (See Figure 3.) This value will vary according to regional
specifications, geometry, and specific requirements for the installation. The
distance for flat ceilings and basic spacing requirements (S) is shown in the
following table.
Standard Distance from Ceiling Maximum Spacing (S)
NFPA 72 300 mm (12 in.) minimum 18.3 m (60 ft)
AS1670.1 25 to 600 mm (1 to 23.6 in.) 14 m (45.9 ft)
BS5839.1 25 to 600 mm (1 to 23.6 in.) 15 m (49.2 ft)
GB50166 300 to 1000 mm (11.8 to 39.4 in.) 14 m (45.9 ft)
For full information on spacing requirements, please refer to your local codes
and standards.

MOUNT THE REFLECTOR USING THE DRILL TEMPLATE
Refer to Appendix II. in Installation guide for drill template instructions.
MOUNTING THE DETECTOR
Remove detachable front rim cover. To detach the Imager part from the
backbox, loosen the 3 holding screws.
To provide cable access to the Termination Card of the Imager remove the
cut-outs from the back, bottom or top of the main assembly by using a sharp
blade to cut around the circular discs.
Secure the back box directly onto the mounting surface using any suitable
number of the 5 pilot holes in the backbox.
Use appropriate fasteners to secure the back box component to the mounting
surface.

WIRE THE TERMINATION CARD ON THE IMAGER
• Wire the initiating device circuit on the Imager Termination Card using
the FIRE and FAULT relay terminals for a four-wire device connection.
(See Figure 5.)
Note: For all relay connections, break wire run to allow monitoring.
• Wire external power to the unit via the POWER terminals. (See Figure 6.)
• Wire the Remote Indicator and/or remote test or reset units if required.
• Securely connect the wires to the plug-in terminals and engage in the
receptacles at the back of the Imager
• Switch on the heater if the installation requires so.
• Re-attach the Imager to the back box
• Remove the protective film from the lens surface of the imager.
• Connect power to the Imager
Note: Analog addressable Input/zone modules can also be used with the
system. For further detail, please consult the relevant FACP Product Guide.

INITIALIZATION AND COMMISSIONING
Ensure that neither you nor any other objects are in the line of sight between
the detector and the reflector and start to manually align the Imager to the
reflector (See Figure 9.)
The OSP-002 Laser Alignment Tool can be used for the rough alignment if
the system is to be installed at longer distances or in heavy lit environments.
Follow these steps to adjust the optical sphere of the detector component to
align the system (See Figure 10.):
• Make sure the lever is the 3 o’clock position.
• The 4 arrows will intuitively guide the user to optimal eyeball alignment.
Likely the alignment process will start with all arrows red.
• Gently move the eyeball until all arrows and the middle green LED blink
green for the eyeball to be optimal aligned (See Figure 11.).
• When all arrows are green, gently lock the eyeball by moving the lever
down till the eyeball is solidly locked. The lever is now in the 5 o’clock
position and you feel the resistance of the locked position.

FIGURE 11. LOCKING AND SECURING EYE BALL
Level down
C2062-00
By locking the eyeball an internal switch is activated and the detector will
now start its initiation or commissioning process. A normal commissioning
process takes roughly 10 seconds. During the commissioning process, the
beam path must remain clear from object intrusions.In this process cycle, the
detector will measure size of the reflector in the FOV and set the sensitivity
automatically to the optimum sensitivity for the specific distance.
Before going in operational mode, the detector will show its set sensitivity.
This is shown by blinking the 4 arrows to the colour yellow, reflecting the %
of selected obscuration/sensitivity. The key is; 1 blink = 25%, 2 blinks =
30%, 3 blinks = 40% and 4 blinks = 50%. After 5 seconds, the scenario will
be repeated a second time and the arrows LEDs go out and the front OK LED
blinks green. The detector is now in operation and working correctly.
The paintable rim can now be snapped over the front to secure the locking
lever and to hide the alignment LEDS and locking mechanism.
Applying the cover also secures the locking lever in position.
TESTING THE INSTALLATION
After the commissioning, the detector must be tested for correct alarming by
using the OSP-004 test filter at the reflector or using the remote test station.
When using the RTS151KEY for testing the detector, the remote fault LED will
blink the set sensitivity of the detector. The number of blinks, similar to sec-
tion 5, will represent the set sensitivity and the sequence is repeated every 3
seconds till the detector is reset.
IMAGER RESET
The fault relay is non-latching but the alarm relay is latching. The Imager
alarm can be reset by shortly dropping the supply voltage or by using a reset
station.
OPERATION AFTER A POWER FAILURE
After a power failure of any duration, when the supply is restored, the detec-
tor will check the possible new situation against its memorized data.
If the reflector is found in the same position and all parameters are within
acceptable limits, the detector will resume its operation and go out of fault
condition.
If any significant parameters have changed, it will remain in a fault condition
and a re-initialization will be required.
