50 - 120m = 4 Reflectors

5m - 120m

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

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

All installations should comply with local

regulations

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:

1. Fire Resistor (Note 1) - value is specified by

the FCP manufacturer.

For U.S. installations it is typically a short

circuit.

2. 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.

Breakwire run to provide monitoring of con-

nections.

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

Stage 1 (Targeting) is the process of using the

laser to get the infra-red beam close enough to

the reflector so that Alignment can begin.

Ensure the targeting setting switch is set to the

left hand position.

To turn the laser on move the slide switch to

the left hand position.

Use the direction keys to move the laser point

on to the Reflector.

If the laser cannot be seen, for example in very

bright environments or over long distances,

then Prism Targeting mode can be used – refer

to the next page.

Once Targeting is complete, move to Stage 2.

Alignment

Fireray One will align in less than a minute if

Fast Alignment is selected. In this mode, the

current consumption during alignment will be

33mA (it will revert to 5mA when alignment is

completed).

To select fast alignment mode, ensure the fast

alignment setting switch is set to the right hand

position

If lower consumption during alignment is

required, then ensure the Fast Alignment

setting switch is set to Off – consumption will

remain at 5mA but alignment can take up to

15 minutes.

Stage 2 (Alignment) moves the infra-red beam

exactly to the middle of the Reflector.

To select auomatic alignment, ensure the

alignment setting switch is set to the left hand

position.

To begin automatic alignment move the slide

switch to the right hand position.

The alignment status LEDs will flash to show

progress:

• The right-hand green LED will flash

continually throughout alignment to indicate

alignment is occurring

• The left-hand green LED flashes to indicate

which stage (1 to 4) the process is at.

• If for any reason the alignment fails the

amber LED will flash, and the number of

times it flashes indicates which alignment

stage failed.

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.

Alignment

Prism targeting should only be used when

the laser cannot be seen, for instance in high

ambient lighting conditions or over very long

distances.

Ensure targeting setting switch is in the right

hand position.

Move the slide switch to the left position.

The green and amber LEDs will flash together

for a few seconds to show the detector has

started Prism targeting.

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.

Prism targeting

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.

Page 13

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

Page 15

Status Indications and Troubleshooting

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.

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.

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.
