FIRERAY 5000-UL Reflective Beam Smoke
Detector
www.boschsecurity.com
u Extended monitoring range
u Up to 2 detectors per system controller
The Fireray5000‑UL Linear Smoke Detector covers
distances between 26.25 ft and 330 ft (8 m and
100 m). A reflective prism allows for the accurate
detection of smoke particles within the given distance
range.
For ranges between 26.25 ft and 164 ft (8 m and
50 m), one prism is sufficient. For ranges between
164 ft and 330 ft (50 m and 100 m), four prisms are
required. The additional prisms are included in the
FRay5000‑LR‑Kit Long Range Kit.
Key application areas are large halls such as historical
buildings, churches, museums, shopping centers,
factory halls, warehouses, etc.
The Fireray5000‑UL Linear Smoke Detector is suitable
for use in areas where point-type detectors are not
effective
The Fireray5000-UL Linear Smoke Detector can be
upgraded with one additional FRAY5000-HEADUL Detector Head. The system controller can control
two detectors. Each head can be programmed
separately.
u Two pairs of fire and fault relays (one per detector)
u Transmitter and receiver integrated into a compact
housing
u Integral LASER alignment
Functions
The transmitter emits an invisible infrared light beam
(850 nm) that is focused through a lens. The light
beam is reflected by the prism 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 (standard
10 s, adjustable), the detector triggers a fire alarm and
the alarm relay closes.
The sensitivity can be adjusted according to the
environmental conditions. The default settings of 25%
(sensitive), 35% and 50% (non-sensitive) can be
changed in steps of 1%. Each detector can be adjusted
individually. The standard setting is 35%.
The alarm relay can be set to auto-reset or latched
mode.
The LEDs indicate three different operating states:
• Alarm
• Fault
• Operation
You can control and set all parameters via the system
controller and LCD display for each detector head.

Slow changes in the operating states (e. g. component
aging, optics contamination, etc.) do not cause false
alarms, but are compensated by the automatic gain
control. Every 15 minutes, the system state is
compared with a default reference value and in the
case of a deviation, is corrected automatically
to 0.17 dB/h. If the compensation limit is reached,
"Fault" the fault signal is indicated.
If the IR beam is obscured within 2 s and the
obscuration is more than 87% and lasts for 10 seconds
and above (operator changeable), the fault relay
switches. Faults may be caused by an obstacle in the
beam path, by the covering of the reflector, etc. As
soon as the fault cause is removed, the fault relay is
cleared and after 5 s, the detector is automatically
reset to standard operation. The fire panel must be
reset separately.
The system has an alarm output, which is a relay with
a potential‑free change-over contact.

Installation/configuration notes
• For connection to FPA-1000 and any UL-listed 24V
control panel.
• The line of sight between the detector and the
reflector always has to be clear and may not be
interfered by moving objects (e. g. overhead crane).
• Heat accumulation under the roof may prevent smoke
from rising up to the ceiling. Thus, the detector must
be mounted below the expected heat accumulation.
Accordingly, the benchmark values for X1 specified in
the table have to be exceeded.
• The mounting surface for the detector must be firm
and vibration-free. Metal supports that may be
affected by heat or cold are unsuitable for the
installation.
• The detector and the reflector are usually installed at
the same height and aligned with one another. The
wide angle of the IR beam allows for an easy
adjustment and for a reliable long-term stability.
• The detector must be mounted in a position where
the detector’s optical system is not exposed to direct
sunlight or artificial light. Normal ambient light has no
influence on the IR beam and the analysis.

• Since the smoke from a fire does not simply rise
straight up, but rather spreads like a mushroom cloud
(depending on air current and accumulation), the
monitoring range is much greater than the diameter
of the IR beam.
• The lateral detection on either side of the beam is
24.6 ft (7.5 m).
• Country-specific Standards and guidelines on
planning must be observed.
Detector arrangement
The detectors must be arranged according to the
following distances:
X1 Distance from the ceiling 1 ft to 2 ft (0.3 m to
0.6 m)
X2 Horizontal distance detector/wall min. 1.6 ft (0.5 m)
X3 Horizontal distance between two
detectors under gable roofs
Example: Gable roof, 10° roof pitch
X3 = 30 ft + (30 ft x 10%)
X3 = 30 ft + 3 ft
X3 = 33 ft
