1, with broadcast PA function and channel intercom function.
2, Squelch technology and high-fidelity PA technology, to maintain a clear call quality in the 120 dB ambient noise.
3, 5 intercom channels, a PA channel, for 5 groups of people to talk at the same time, there is no interference between each other.
4, the shell is made of aluminum alloy, the appearance of spray, nice, safe and reliable.
5, station phone does not reset the rest of the system can still work.
6, the system uses the bus structure, all the explosion-proof station are parallel to the two signal bus, and no polarity difference, the installation can be adjusted connection, greatly simplifying the system connection, reducing the project cost. Do not need traditional program-controlled switches to achieve mutual communication, two or more explosion-proof station connected to form a communication.
1, HWB-A explosion-proof phone station for petrochemical, coking, steel, docks, ships and other often need to work with the location of the uncertain scheduling of production scheduling contact, or emergency handling, or production operations on the operational control.
2, to eliminate the blind spot of public address calls, to achieve comprehensiveness, timeliness and convenience, thereby improving work efficiency and ensuring the safety of production.
3, the explosion-proof station has the advantages of easy to use, easy installation and maintenance, good call effect, large power amplifier, cost-effective, wide range of applications. For space, noisy environment, scattered positions, for the production scheduling and liaison communications.
1, easy to use, without dialing, pick up the phone can enter the call state, you can start to find someone on the radio, the phone is looking for someone near the machine automatically cut into the call channel, enter the two conversations, the speaker automatically cut off, if someone else Conduct a call, repeat the above action into another channel for dialogue, can be simultaneously for five groups of people call each other without disturbing.
Automatic gain, enabling long-distance communications, up to 5 km.
