Operation
Dip-switch setting
Convetional detector driving unit
During an alarm, it
interrupts
the power to the zone to
reduce the consumption
During an alarm, the
power of the zone remains
in order to indicate which
detector issued the alarm.

Connecting a BSR-8020/WP with conventional detectors
.
A 10k
Ω
terminal resistor must
be connected on the last detector
.
The maximum number of detectors per unit is 10.
An
external LED BS-572 can be connected on one of the detectors. With the dip-switch
8
we
can set if during an alarm the zones power will be interrupted or not.
(
according to the
table above
).
If the dip-switch 8 is in the ON position, the maximum number of devices is
7, whereas if the dip-switch 8 is in the OFF position, the maximum number of devices is
30. The total consumption must also include the consumption of the other devices.
