olympia electronics BS- 655/A User manual

They are composed by two parts. A plastic base which is placed on the ceiling and the main
body of the detector which fits on the plastic base with a simple rotation to the right. The
o
detectors have a 360 visible led and a remote led driver which are light up constantly in case
of detection of fire, till cancelled from the panel. They are turned off only when a reset
command is given from the panel. The indicator led blinks every 6 sec indicating the normal
function.
The detector has fault diagnosis and dust compensation functions, which automatically
informs you through the onboard LED when replacement or cleaning actions are required.
The indication LED blinks every 7 seconds. In normal operation it blinks 1 time, if cleaning
action is required it blinks 2 times and if there is a failure it blinks 3 times. After cleaning
procedure it will take about 10 minutes for detector’s working indication to return to normal.
GENERAL
The user have to read carefully the following instructions, in order to be properly informed and
keep them for future use.
The BS-655/A is a conventional smoke detector which integrates function of optical smoke
detection. The detector transitions to alarm state when the concentration of smoke reaches
0.107dB/m.
INSTALLATION
The detectors should be placed in the ceiling in visible points without side obstacles, away
from places that are barely ventilated or with strong air currents and water vapor. Each
2
detector covers an area of 50 m while the distance between two detectors should not be
more than 15m. Also, they must be placed at least 50 cm away from fluorescent lamps. Cable
diameter should be from . to .0 5 2 5mm.

ooptically visible LED.
In every device there is a double sticker with the UID (Unique Identifier) number. This
number is unique for each device.
UID:
These functions combined with periodic manual testing ensure maximum security level. The
manual testing procedure is carried out by spraying a small amount of smoke into the detector
with an A-752 spray or a counterpart product. It is suggested to carry out a test every 6 months
or after a change in the position of the sensor. A key element of its proper function is the air to
be able to freely circulate inside it. So be careful not to block the openings of the outer cover.
Before the manual testing it is suggested to enable the special “walk in test” mode from the
panel.
CAUTION !!
After installation the device must not be covered with dust or be painted or anything else
happen that will block the smoke to get to the sensor. Special attention must be given during
the installation and the use of the device, since the user assumes full responsibility for proper
operation afterwards.
Also, during site works place the plastic cover to the detector as shown in the picture below to
protect the device from dust.
- Automatic fault diagnosis.
- Dust compensation and automatic indication when cleaning is required. Stable
level of detection regardless of detector’s working hours.
- Integration of dynamic algorithms for noise and false alarm rejection.
Additional features of the device :
- Compensation of smoke measurements based on ambient temperature which
ensures high precision measurements even under extreme environmental
conditions.

5. : Connected to the cable’s shield (when shield is used).
2. - IN : It is connected to the zone of the panel or to the (- OUT) contact of the
previous detector.
4. - R : It is connected with BS-572.
1. + IN/OUT : It is connected to the zone of the panel or to the (+ IN/OUT)
contact of the previous detector.
CONNECTION
3. - OUT : It is connected to the next detector (- IN) or if it is the last one to the terminal
resistor.
1. Remove the detector from its base rotating to the left till the side marks are aligned.
2. Fasten the base with the supplied mounting materials (point 5).
3. Connect the power cables (minding the correct polarity) according to the requirements of
the installation (Figure 1, 2).
4. Place the detector carefully so that the side marks are on the same position and rotate the
detector clockwise until it locks. Power the device and after 3-5 seconds it is ready for
operation.
