1. IN-OUT -L : It is connected to the zone of the panel or to the (IN-OUT -L) contact of the
previous detector.
4. IN +L : It is connected to the zone of the panel or to the (OUT +R) contact of the previous
detector.
3. OUT +R and -R : It is connected with BS-572.
1. Detach the detector from it’s base by turning it anticlockwise until the side marks are aligned.
3. Connect the power cables (respect to polarity) according to the installation requirements (figure
1,2).
2. Install the base with the included mounting parts (point 5).
Power the device and after 3-5 seconds will be ready to operate.
2. OUT +R : It is connected to the next detector (IN +L) or if it is the last one to the terminal resistor.
CONNECTION
4. Place carefully the detector, so as to align the side marks and turn it clockwise all the way.

If the power of the detectors is turned off, wait for 3-5 seconds before you turn the power on again.
You can connect up to 30 detectors BS-657 on each zone.

The detectors BS-657 were created to offer
quick detection in case of fire.
To test the optical detector you can spray a
small amount of smoke into the detector’s
chamber. You can use the special smoke
device A-752 of our company, or a similar
device. To check the thermal limit you need a
special tool.
The detectors must be placed in the ceiling on
They have two parts, one plastic base which is
installed on the ceiling and the main unit of the
detector which is fastened to the base by a
simple turning to the right. The detectors have
an indication led which lights continuously in
case of fire detection until there is a reset
signal from the panel. The indication led also
flashes every 4 sec to indicate good operation.
These detectors can cooperate with
conventional fire alarm panels like BS-632 and
BS-636.
It is advised to conduct a good operation test
every 6 months and every time the detector
position is changed.
NOTE
Before installing the detector, the user must
read these instructions carefully and store this
manual for future reference. The BS-657 is
optical smoke and thermal detector.
GENERAL
OPERATION CHECK
It is essential to have good air circulation inside
the detector. Therefore care must be taken so
that the vents of the detector are not covered.
visible areas with no side obstacles and away
from sides with no air circulation or strong air
currents and vapors. Each detector covers
2
almost 50 m and the distance between two
detectors must not exceed 15m. Also the
detectors must be placed away from
fluorescent tubes at least 50 cm.
The cables cross section must be from 0.5 to
2
1.5mm .
ATTENTION!!
After the device is installed, care must be taken,
so that the detector vents are not blocked by
anything (i.e. dust, paint). Failing to do so will
prevent the smoke particles to enter the
detection chamber.
After th e inst allation , it is th e so le
responsibility of the user to maintain the
detector for good operation.
