If the sounder/sounder strobe is required
anti-removal, knock down the arch knock-off hole as
shown in Fig. 1 and fix it with ST2.9
×
6.5 tapping
screws (in this case, it must be removed by a special
tool).
Application
the sounder/sounder strobe can match I-9333
Interface to form an intrinsically safe system. The
system wiring is shown in Fig. 5.

Cautions
1
．
I-9333 Interface should be installed in safety
area, the wires of "Safety Area" should be
separated from those of "Hazardous Area", and
be kept a certain distance (at least 50mm).
2
．
The safety barrier should be well grounded.
The screws should not be loose. Ground
resistance should not be over 1
Ω. The
parameters assigned in the intrinsically safe
loop should not be over the specified value, that
is, the capacity assigned among cables should
not be over 0.02μF, the inductance assigned
not over 2mH.
3
．
During maintenance, products passing the
explosion-proof test should not be replaced and
parts and structure affecting explosion-proof
functions should not be modified.
