How does it compare to walkie-talkies or explosion-proof phones? A few years ago, large-scale chemical plants were keen on using audio intercom systems; I wonder if they are effective? How does it compare to the explosion-proof phones or walkie-talkies that have emerged recently? If it works well, which brand is better? Could the expert give us an introduction, please? Thank you!
It depends on the requirements on site; if mobility isn’t very high, it’s best to use amplification to avoid the inconvenience of carrying a walkie-talkie. For those who are highly mobile, it is necessary to carry a walkie-talkie for easy communication. Choosing a brand is no longer a problem these days; you can just pick any well-known company. .
In our company: All middle-level managers and above are equipped with explosion-proof phones and explosion-proof walkie-talkies； In the workshop, daily communication is carried out via walkie-talkies or landline phones; emergency loudspeaker systems are only used in case of accidents
Due to the noise at the scene, it’s impossible to hear what’s being said in the emergency announcements The emergency phone on site does work, but having a walkie-talkie is more convenient; it’s meant for use in emergencies only. Not having been used for many years, it’s likely that many people have forgotten there is an emergency phone number on site.
Public address intercoms are generally used for emergency calls; they are not effective when used for normal operations.
We use explosion-proof phones. I don’t know if it’s legitimate or not; anyway, it’s said to be explosion-proof: lol
Intercoms are definitely the most practical option. In our previous workplace, we first used loudspeaker systems, but it was impossible to hear anything clearly at the work site; as a result, no one used them after just a few attempts. There were also explosion-proof phones, but they were located in fixed places. Who would go away from their work just to make a call? Everyone preferred to use intercoms – whether working inside towers or tanks or for any other tasks, they are an essential tool.
Using a broadcast intercom system during emergency situations can take advantage of the benefits of broadcasting, but for regular use, phones are better; walkie-talkies are more convenient, provided they are explosion-proof. This also prevents employees from carrying ordinary phones with them, which could lead to accidents, achieving multiple benefits at once. Brands like Motorola are all good.
There is no absolute explosion protection; static electricity poses a risk that no one can afford to take on.
Motorola’s analog signals are good, but its digital signals have latency
