product description:

l With broadcast amplification and channel intercom function.

l Squelch technology and high-fidelity PA technology to maintain clear call quality in 120 dB ambient noise.

l 5 intercom channels, 1 sound reinforcement channel, for 5 groups of people to talk at the same time, there is no interference between them.

l The shell is made of cast aluminum alloy, and the exterior is sprayed with plastic, which is beautiful and safe.

l Other extensions in the system can still work when the station phone is not reset.

l The system adopts the bus structure. All the explosion-proof stations are connected in parallel to the two signal buses, and there is no polarity difference. The connection can be adjusted during installation, which greatly simplifies the connection of the system and reduces the construction cost. Communication with each other can be realized without the need of a traditional program-controlled switch, and more than two explosion-proof stations can be connected to form a communication.

Features:

l HWB-A explosion-proof station is suitable for petrochemical, coking, steel, wharf, ship and other people who often need to make production dispatch contact with emergency personnel, or emergency handling, or operation control on production operations.

l It can eliminate the blind spot of the amplified call, achieve comprehensiveness, timeliness and convenience, thereby improving work efficiency and ensuring the safety of production.

l The explosion-proof station has the advantages of simple use, convenient installation and maintenance, good call performance, large power amplification, high cost performance and wide application range. It is suitable for places with large space, noisy environment and scattered posts, used for production scheduling and communication.

Instructions:

l Easy to use, no need to dial, pick up the phone to enter the full call state, you can start broadcasting to find someone, the phone close to the person who is looking for the person will automatically cut into the call channel, enter the conversation between the two, the speaker will be cut off automatically, if another person Call, repeat the above actions to enter another channel for dialogue, and can simultaneously provide 5 groups of people to talk without mutual interference.

Automatic gain for long-distance communication up to 5 km.
