1. 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.

5. 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.

6. 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 D

H

 The distance between two parallel beams may not be greater than the doubled

distance D D

H

 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).
