When the detector is to be connected with I-9332 Interface
or Explosion-proof
Manual Call Point in series, a 4.7kΩ
end-of-line resistor connected to the end of loop.
There are three conductive elements on the base with
terminals. The bases are connected in series with an
end-of-line resistor connected at the end. Please note
polarity when connecting the system with the method
shown in the above figure.
The interface is integrated with a safety barrier, which
shall be installed in safe area. The total number of
explosion-proof devices connected in the system shall
not be over 10.
Troubleshooting
No alarm: First check external wiring and screws when
there is a problem. If there is no problem, return it for
repair.
False alarm: Return it for repair.
Maintenance
The detector should be installed just before
commission and kept well before installation, with
corresponding measures taken for dust-proof,
damp-proof and corrosion-proof.
The dust-proof cover should not be removed until
the project is put into usage.
Fire test should be done at least once every 6
months.
Cautions
I-9332 interface box 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).
The safety barrier should be well grounded. The
screws should not be loose. Ground resistance
should not be over 1
Ω . The assigned parameters in
the intrinsically safe loop should not be over the
specified value, that is, the capacitance distributed
among cables should not be over 0.083
μF, and the
inductance distributed should not be over 4.1mH.
During
maintenance,
products
passing
the
explosion-proof test should not be replaced and
parts and structure affecting explosion-proof
functions should not be modified.
