General Information
Installation
All installations should comply with local regulations
Do NOT position Detector where personnel or objects can enter the beam path
Do NOT install the Detector or Reflector in environments where condensation or
icing are likely to occur unless preventative measures have been taken
Position beam as high as possible, but with a minimum distance of 0.3m from
Detector and Reflector to ceiling.
For detectors approved to UL268 refer to NFPA72 for installation guidance. In
such installations, it is advised that the maximum distance of Detector and
Reflector from the ceiling must be 10% of the distance between floor and
ceiling
Ensure correct Reflector selected for the appropriate distance
Mount Detector and Reflector directly opposite each other
Do not mount Reflector onto reflective surfaces
Wiring
The Fireray One contains software that processes the output of the detector
and generates a Fire and Fault status. This status is output using volt-free
relays so that it can be interfaced to all types of conventional Fire Control
Panel (FCP). To wire a single Detector to an FCP, use the following wiring
diagram.
Components not supplied:
-
Fire Resistor ( Note 1) – value is specified by the FCP manufacturer.
For U.S. installations it is typically a short circuit. -
End Of Line (‘EOL’) component – supplied by FCP manufacturer
After installation, check operation of Fire and Fault connections to the FCP –
see page 15.
Apply a voltage of 5V to 40V to ‘Ext Reset’ contact for at least 2 seconds to
clear a latched fire condition – see page 14 for latching mode setting.
CAUTION: For system monitoring – Do not use looped wire under any
terminals.
Break wire run to provide monitoring of connections.
When using more than one Detector on a single zone of a conventional FCP, it
is important to choose the correct method of wiring. Incorrect wiring may
result in a Detector isolating subsequent devices on that zone if it enters a
Fault condition, and may prevent these subsequent devices signalling a Fire
condition back to the FCP.
If the FCP monitors for point detector removal, it is possible to use the
following wiring diagram which uses a diode to provide zone continuity in the
event of a Fault state on any Detector.
Recommended diode type: Schottky, 60 Volt, 1 Amp, must be UL listed for
installations meeting NFPA72
Mounting
Mount Base
Mark and drill holes for mounting of Base.
Using appropriate hardware (not supplied) mount base securely in orientation
shown.| Plug the cable from the Detector head into the
connector on the PCB in the Base.| Locate the Detector Head on the base.
Grip sides of Detector Head and rotate clockwise
to lock together.

If alignment fails, ensure that the correct number of reflectors are
installed, that the correct clearance has been given, and that there are no
reflective surfaces around the reflector or close to the beam path, and try
the alignment again.
If alignment repeatedly fails, it is possible to do a manual alignment.
Once the alignment is successfully complete, the right-hand green LED will
flash for 10 seconds.
The Fire and Fault relays will go to normal state, and the Detector will flash
its status indicator green every 10 seconds.
You are now ready to select Alarm Thresholds and Latching mode, and to test
the Detector to ensure it is operating and connected to the Fire Control Panel
correctly.
Prism targeting
Prism targeting should only be used when the laser cannot be seen, for
instance in high ambient lighting conditions or over very long distances.
If the green LED stays illuminated the Detector is receiving
enough light back from the Reflector. Cover the reflector – if the green LED
goes off then the light being received by the Detector is coming from the
Reflector and you can now proceed to the Alignment stage. If the green LED
stays illuminated with the reflector covered then the light received by the
detector is being reflected by some other object in or around the beam path.
Take care to make sure there are no reflective objects within 0.5m of the
centre of the beam path, and try Prism Targeting again.
The amber LED will flash every two seconds if the Detector is not receiving
enough light from the Reflector. The number of flashes indicate how strong a
signal it is receiving. Using the direction buttons, move the detector in one
axis until the amber flashes increase. If the number of flashes stays the
same, then keep going in the same direction. If the number decreases then
reverse direction. Once the number of flashes starts to increase then keep
going until either:
- The green LED comes on, at which point cover the reflector as described above
- The amber flashes start to decrease again, at which point reverse direction for 2 steps and perform the same process in the other axis
If Prism Targeting has been performed on both axes and the green LED is still not on then ensure that the correct number of reflectors for the range has been used, that the distance has not exceeded the maximum (120m/394ft) and that the reflector and detector are parallel to each other.
Manual Alignment
Manual alignment should only be used when Automatic alignment has failed
even after it has been verified that the correct number of reflectors have
been installed and the correct clearance around the beam path has been given.
Perform targeting as previously described
Ensure Setting Switch 1 is in the right-hand position, and move the Slide
Switch to the right-hand position
The green and amber LEDs may flash if the detector needs to perform an initial
power adjustment
Once the LEDs have stopped flashing, use the direction buttons to move the
detector in the up-down axis. First, use the direction button in the down
direction. Press the button once, and wait to see what the LED indication
shows. If both amber and green LEDs flash, the signal has not changed so no
further movement in that axis is needed.
If the amber LED flashes, the signal is smaller and the detector is moved away
from the reflector. The next movement must be in the opposite direction. Using
the direction buttons, move the detector again – this time there should be a
green flash.
If the green LED flashes, the signal is larger and the detector is moving
closer to the reflector. The next movement must be in the same direction. Keep
moving the detector, waiting for the LED flash each time. If the green LED
keeps flashing, keep going in the same direction. If the amber and the green
LED flashes, then move onto the other axis. If the amber LED flashes, move
back in the opposite direction once, then move onto the other axis.
Follow the same process with the direction buttons, this time in the left-
right axis. Start by moving the left direction, and follow the same LED
flashes as described in the up-down axis.
Once the alignment has been completed on both axis then move Setting Switch 1
to the left-hand position. The right-hand green LED will flash for 10s, the
Fire and Fault relays will go to normal state, and the Detector will flash its
status indicator green every 10 seconds.
You are now ready to select Alarm Thresholds and Latching mode, and to test
the Detector to ensure it is operating and connected to the Fire Control Panel
correctly.

UL Sensitivity Acceptance Test
Successful alignment of the Detector will check correct operation of the
Detector and its sensitivity level.
Latching Mode
The Fire state will automatically clear once the signal strength has recovered
unless Latching Mode has been selected. To select Latching Mode move the
Latching Mode switch to the On position.
External Reset
If Latching mode is selected then to clear a fire condition remove power for
longer than 10 seconds or apply a voltage of greater than 5V to Ext-Rst for
longer than 2 seconds.
Status Indications and Troubleshooting
Status Indications
During normal operation the Detector Status indicator LED will flash green
every 10 seconds, and both Fire and Fault relays will be in their normal
position.
If the detector is in Fault state, its LED will flash amber every 10 seconds
to indicate
Signal High/Low Fault, every 5 seconds to indicate AGC/Compensation Fault, and
every 3 seconds to indicate Internal Fault. The Fault relay will change state.
If the detector is in Fire state, its LED will flash red every 10 seconds and
the Fire relay will change state.
Cleaning
The Detector will automatically compensate for dust build up by changing
its AGC level.
Once the AGC limit has been reached, the Detector will indicate a Fault and
cleaning must be performed.
It is therefore recommended that the Detector lens windows and the Reflector
are periodically cleaned with a soft lint-free cloth to prevent AGC limit
faults occurring.
After cleaning, if the Detector is in Fault state, the signal strength may
have increased above the Signal Too High threshold. If this is the case, re-
align the Detector.
Testing
After installation or cleaning it is recommended that a Fire and Fault test is
performed.
Fire Test: Cover the reflector slowly so that it takes longer than 5 seconds
to cover. The Detector will indicate Fire after 10 seconds.
Fault Test: Cover the reflector completely
within 2 seconds. The Detector will indicate Fault after 10 seconds.
