The above functions are set using the dip-switches 9 and 10. The dip-switch 8 determines a
sub function depending on the case.
1) Input/Output Unit
In this function input and output units are independent.
The device has 4 different operation modes:
2) Input unit
OPERATION
The input unit with auxiliary relay is used so as to provide an additional input to the loop. Gas
sensor types BS-685 and BS-686 can also be connected. It contains an input that is fully
monitored for open and short circuit conditions and a relay (1A/30V), which is activated for 5
seconds after a panel reset (when the dip-switch number 8 is in the OFF position). On the
panel, the input units are shown as “INPUT UNIT ΧΧΧ” (where ΧΧΧ is the set address of the
device). In this function, the terminal resistor is 56kΩ and the alarm resistor is 10kΩ.
The input unit is used in order to connect non addressable devices, that have a free relay
contact (such as conventional alarm panels, or flow switches), to the loop of the panel. The
input unit is fully monitored and has the capability to send to the panel, with a suitable
connection, three states: quiescent, fault, alarm. The output unit contains a relay that is fully
programmable from the panel with a rating of (30V/1A). The red LED which blinks periodically
in the quiescent state is a power and good operation
indication. On the panel, the input unit is
shown as “INPUT/OUTPUT UNIT ΧΧΧ” (where ΧΧΧ is the set address of the device). In this
function, the terminal resistor is 56kΩ and the alarm resistor is 10kΩ.
3) Conventional detector driving unit
The driving unit for conventional detectors is used in order to connect conventional detectors
to the addressable panel. The device can be connected to the BSR-2104 and BSR-2114
panels. It can power up to 10 detectors and has protection against the detection of an open
circuit or the disconnection of a detector. A 56kΩ resistor is installed by default on the
terIN, -IN. We replace the 56k
Ω
resistor with a 10k
Ω
resistor. We install the 10k
Ω
resistor to the last detector of the line. On the panel, the input unit is shown as ``ADAPTOR
UNIT ΧΧΧ`` (where ΧΧΧ is the set address of the device). The LED lights and remains lit
when the specific input unit issues an alarm to the panel. The LED also remains lit if the sirens
are deactivated from the panel. The LED of the detector that issued the alarm also remains lit
in order to show the precise alarm origin. LED is turned OFF after a panel reset. In this
operation we have increased consumption and cannot connect more than 7 BSR-8020/WP
on each loop. In this function the terminal resistor is 10kΩ and the alarm resistor is 1kΩ .
This function is the same as the previous one. The only difference between the two, is that an
external power supply is used. The external power source must have an output rating of 21-
28V and must not be interrupted during a power failure.In this function the terminal resistor is
4.7kΩ and the alarm resistor is 1kΩ .
