Product Description
The Fireray 50/100RV is a linear optical black and white smoke detector. The detector
is a retro- operation device, i.e. the transmitter and the receiver are located in one
housing with the control unit. A prism reflector is mounted opposite the detector and
reflects the infrared beam to the transmitter/receiver combination. If smoke penetrates
the section under surveillance, the beam to the receiver, thus the infrared signal
received, is smaller. The volume of smoke is assessed and the detector triggers a fire
alarm after a specified period of time.
The Fireray 50/100RV smoke detector comprises two components:
- Compact housing with infrared sensor, receiver and control unit
- Prism reflector.
There are two Fireray variants:
- Fireray 50RV with a range of between 5 m and 50 m
- Fireray 100RV with a range of between 50 m and 100 m.
If this documentation refers to both variants, they are combined under the designation
Fireray 50/100RV.
It is also possible to connect a key switch, which is mounted within reach, via the
RS- 485 interface. Alarm tests can be triggered using the key switch without having
to reach up to the detector. In addition, the set parameters, the detector status and the
current signals can be read and the parameters can be changed. An interface adapterand the Data Viewer software (CD) are also required.

Functional Description
The transmitter emits an infrared light beam (880 nm) that is focused through a lens
and invisible. The light beam is reflected by 180 by the prism reflector mounted
opposite and returned to the transmitter/receiver combination.
If the IR beam is obscured by smoke and the signal received drops below the selected
threshold value for 10 s, the Fireray triggers a fire alarm and the alarm relay closes.
The activation threshold can be adjusted to the environmental conditions. Settings
25% (sensitive), 35%, and 50% (non- sensitive) are possible.
The alarm relay has two operating modes:
With Auto Reset, the alarm relay releases again if the volume of smoke drops below
the selected alarm threshold for at least 5 s.
In Alarm memory mode, the relay remains active until it is reset. To reset, power is
dropped to the detector for at least 5s.
Slow changes to the operating states (e.g. aging of the components, contamination
of the lenses, etc.) do not cause false alarms; instead, they are balanced out by the
automatic gain control. The state of the system is compared with a default reference
value every 15 minutes and in case of deviations, compensated automatically up to
0.7 dB/h. If the readjustment limit is reached, any further signal decay will trigger a
«malfunction» (DIP switch 2 = on) or an «alarm» (DIP switch 2 = off).
If the IR beam is obscured for at least 10 seconds by more than 90% with a sharp signal
increase, the fault relay switches. The cause can be a blocking of the beam path,
detector misalignment, blocking of the reflector, etc. After eliminating the cause of the
malfunction, the fault relay is reset and the detector is reset automatically into the
detection - ready state after 5 seconds. The malfunction must be reset at the control
unit.
The detector has an alarm output in the form of a potential free, latching dry contact.

Planning Notes
It is very important that the system be carefully planned and precisely adjusted, to
ensure that the detector responds as early as possible.
The response time of the system is dependent on the installation location, the volume
of smoke generated, the ceiling construction and air ventilation.
Note: Since the smoke over a fire source does not just climb vertically upwards, but
rather spreads like a mushroom cloud (depending on existing air currents and air
pockets), the breadth of the monitoring area is much greater than the diameter of the
IR beam.
According to VdS 2095 and DIN VDE 0833- 2, the number of light beam smoke
detectors must be selected so that the maximum monitoring range A specified in
the table is not exceeded.
The detectors must be distributed such that no point of the ceiling is further removed
from the beam center (horizontal distance) than is specified in column DH
The distance between two parallel beams may not be greater than the doubled
distance D DH
The center line of the monitoring beam may not be closer than 0.5 m to walls,
equipment or stored goods.

With a room height of more than 12 m, it is recommended that you provide a second moni
toring level on which the detectors are arranged offset to the first monitoring level. Depends on the use and environmental conditions (e.g. rapid fire development and smoke
dissemination)
There must be a constant visual line between the detector and reflector, which may
not be interrupted by moving objects (e.g. overhead crane).

Heat accumulation under roof surfaces can hinder the travel of climbing smoke to
the ceiling. The detector must therefore be mounted below an expected heat
accumulation. This can mean that the benchmark values for DL specified in the
table must be exceeded.

Mounting Tips
Observe the planning notes in Section 6.
Usually, the detector and the reflector are installed at the same height and oriented
towards each other. The relatively broad angle of the IR beam eases adjustment
and guarantees reliable long- term stability.
The mounting surface for the detector must be firm and vibration- free. Metal
supports that can be influenced by heat or cold are not suitable for installation.
The detector must be installed such that sunlight and artificial light do not beam
directly into the detector’s lenses. Normal environmental light conditions have no
effect on the IR beam and the evaluation.
Mount the reflector on a solid surface at the permissible distance. Ensure that the
light beam meets the reflector on the vertical.
The reflectors must not be mounted on reflective surfaces such as glass or plain
sheet surfaces. Additional reflections lead to malfunctions.
For protection against radio interference, use a shielded cable. When you are
installing the cable, possible sources of disturbance must be circumvented and the
cable must be protected against mechanical damage.
A 6 DA mini distributor (product ID 2.798.400.302) is required for wiring.
7.1. Connections and DIP switch settings
The operating mode switches, DIP switches and terminal strips for the plug
connector (see Fig. 3.) are located on the back of the detector.

7.2. Mounting the Fireray 50/100RV
To make mounting easier, you can remove the detector cover by gently raising the
upper and lower edges.
The mounting slots (see Fig. 3.), which are positioned at a 90angle, enable vertical
or horizontal mounting of the detector.
Locate the four bore holes at the mounting location using the detector base plate.
Observe the planning notes and mounting tips!
Check the plug connector and the DIP switch settings (see Section 7.1.).
Secure the detector using four screws.
Refit the detector cover.
If a key switch is required, a two- wire cable should be routed from the
detector within reach during installation (see Section 7.4. for connection
details).
7.3. Mounting the prism reflector
Select the mounting location in line with the mounting tips (Section 7.).
A prism reflector must be used for the Fireray 50RV, and four prism reflectors
arranged in a square for the Fireray 100RV.

Start- Up
8.1. Setting up the detector
Start the «Prism Targeting»mode by moving the operating mode switch (see Fig. 3.)
up (if the detector is mounted vertically) or to the right (if the detector is mounted
horizontally).
Connect the power supply.
The detector runs in initialization mode for approx. 5 s.
As soon as the detector is ready for use, the red LED flashes (once with the Fireray
50RV and twice with the Fireray 100RV).
Now direct the detector at the prism, using the two knurled screws, until optimum
adjustment is confirmed by a steady yellow LED light. The following LED displays
support detector set- up:
Yellow LED display
Detector status in «Prism Targeting» operating mode
off
No signal at receiver
Flashes
-> Flashing frequency increasing
Signal is received
-> The faster the flashing, the stronger the signal!
Steady light
Optimum alignment achieved
The signal must only move from the reflector to the receiver,
under no circumstances must it move to other light sources or
reflective surfaces!
Cover the prism reflector with a non- reflective material to check. The LED must not
be lit. If the yellow LED does not go out, this indicates that a reflector is incorrectly
aligned.
8.2. Calibrating the detector
Once the optimum detector set- up has been achieved, set the operating mode
switch to the center position without displacing the detector. The detector is now in
(«Alignment Mode»).
The detector runs through an automatic configuration procedure to optimize the
transmission power and the receiver sensitivity. The following detector statuses
may be displayed by the LEDs during this procedure:
LED displays
Detector statuses in «Alignment Mode»
Flashing red
Receiver input signal too strong, the transmission power will be reduced. Wait until the LED goes out (max. 20 s).
Steady yellow light
No signal is being received. Switch back to «Prism Targeting» mode
and repeat the detector set-up.
Flashing yellow
The receiver is receiving a weak signal, the transmission power will
automatically be increased.
off
Transmission power and receiver gain are optimum.
Flashing red and yellow
Automatic calibration in progress.

When the calibration procedure is complete, move the operating mode switch (see
Fig. 3.) to the bottom (if the detector is mounted vertically) or to the left (if the
detector is mounted horizontally). The detector is now in «Operating Mode».
The detector runs a calibration test for approx. 60 s. If the yellow LED lights up as
a steady light after the test, you must repeat the detector alignment and calibration
procedures (see Sections 8.1. and 8.2.).
If a detector alarm is reset in normal mode by a disruption to the power
supply, the detector automatically runs a calibration test. If the test is
failed, the detector remains in the alarm position. If the test is positive,
the yellow LED goes out, the fault relay is reset and the detector is
returned to normal mode.
In normal mode, the yellow LED flashes every 10 s.
8.3. System test
The «Alarm» and «Malfunction» functions must be checked before final start - up.
Alarm test
Hold the test filter in front of the receiver lens (upper or right- hand part of detector).
Select a volume of smoke slightly greater than the threshold set for the detector (see
Section 7.1.). Make sure that you do not also cover the transmitter -lens.
After approx. 10 s, the red LED must light up and the alarm relay must close.
With the «Save alarm» detector setting (DIP switch 1 «off»), there must be a reset
at the control panel or the power supply must be disrupted for at least 5 s.
With the setting «Auto Reset» setting (DIP switch 1 «on»), the alarm is reset
automatically if the volume of smoke falls below the selected alarm threshold for at
least 5 s.
Fault test
Cover the reflector with a non- reflective material.
After approx. 10 s, the yellow LED must light up and the fault relay must open. As
soon as the obstruction is removed, the detector returns to normal mode
automatically after approx. 2 s.

beam axis.
Cover reflector with a dark material to
test! Check detector’s range of vision
for reflective objects!
An object placed in the beam path for
testing has acted as the reflector.
For testing, use a non-reflective
material, maintain a greater distance
to the detector, cover the reflector as
directly as possible.
Sensitivity to existing environmental
conditions set too high
Set a less sensitive alarm threshold
(DIP switches 3 and 4):
normal= 35%, less sensitive= 50%
