1. Mounting Tips
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.
There must be a free visual line between the detector and
reflector. The IR light beam must not be blocked by moved
objects!

1.2. 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. 2.), which are positioned at a90angle, 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 1.1.).
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 to
the desired location during installation.
1.3. Mounting the prism reflector
Select the mounting location in line with the mounting tips (Section 1.).
A prism reflector must be used for the Fireray 50RV, and four prism reflectors
arranged in a square for the Fireray 100RV.

2. Start-Up
2.1. Setting up the detector
Start the «Prism Targeting»mode by moving the operating mode switch (see Fig.
2.) 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. The red LED flashes if the
detector is operational: 1 x for Fireray 50RV, 2 x for 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 in-
creasing
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.
2.2. 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 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 2.1. and 2.2.).
If a detector alarm is reset in normal mode by a disruption of 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.
2.3. 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 1.1.). 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.
3. Tips on Maintenance and Service
For maintenance and inspection work on danger detector systems, in Germany
the regulations of DIN VDE 0833 apply, which refer to the maintenance interval
according to the manufacturer’s instructions.
Bosch ST recommends a functional and visual inspection at least once a year.
Maintenance and inspection work should be carried out regularly and by trained
personnel.
