Testing, Installation, Wiring
Testing: the end user should test the device after unpacking the
shipping carton. Testing guidance is as follows:
There are 2 conducting wires lead from the cable inlet of the device,
connect the audio signal wires to the conducting wires, must pay
attention to the polarity (red is negative pole, green is positive pole),
if the speaker present a sound for duration of several minutes, that
means the product is qualified.
Note:The conducting wires is only for user testing purpose. When the
device is connected to public amplifier system, the conducting wires
should be removed, instead, use at least S=1.5mm
2
cross-sectional
area cable to connect it , Otherwise, the detector will lose its
explosion-proof performance.
Installation:
(1) Connect the megaphone to the explosion-proof chamber with
three pieces M4 screws, screw the reflector to the threads of
explosion-proof chamber.
(2) Connect the assembled speaker to the wall or roof beam with
two pieces M8 screws.
(3) Use M8 bolts to tighten the speaker.
Cable Lead-in Device: class II B adopts gland nut sealing ring structure
class II C adopts stuffing seal structure.
Wiring: Loosen the fixing screw of the device’s outer housing and
open the explosion-proof chamber. Connect the audio signal wires to
the wiring terminals, must pay attention to the polarity (red is
negative pole, green is positive pole). After wiring is completed,
please well installed the explosion-proof cover to the explosion-proof
body. Be careful not to mix wires or other foreign objects on the
explosion proof surface.
Precaution
1. It is strictly forbidden to disassemble the electrified device in
flammable and explosive places.
2. Keep the explosion proof base clean and dry, be careful not to
damage it during installation. The fastening screws of the
explosion-proof base should be tightened. Be careful not to mix
foreign objects on the explosion-proof base.
3. If the device is in long-term use, please maintain it regularly, make
sure the device is in good condition and with good performance.
Please give to professionals for repair if the device has any failure or
