Figure 3a and 3b shows the connection of
multiple detectors in a network connection , for
covering a larger area and using one
12
VDC NO
electro-valve or one
12
VDC NC electro-valve
Attention!!
The position link of JMP1 set the
relay status.
If a link is set on A ( figure 3B ) the relay is
energized (NO) in normal condition and on alarm
or fault condition the relay is not energized.
The oppisite occurs if a link is set on B ( figure
3A).
ATTENTION:
If you use electrovalves 230VAC
you can use a fire-siren 230VAC BS-546 and
BS-542 . The connection of BS-546 show in
figure 5. If you use electrovalves 12VDC you can
only use BS-542 .
ATTENTION!!
The devices must not be tested
using gas filled lighters because the sensor will
be destroyed.
