For alarms installed in dust-explosion-proof areas, is it necessary to use power cables for the power supply? Can a 1*2*1.5 cable from a computer be used? Are there any regulatory requirements?

It can be replaced with a computer cable; using a power cable would be better

No one will care if you use single-core BV wire; just ensure it is explosion-proof!

And alarm systems are usually three-wire systems, right? A regular 3*1.5 computer cable will do; that’s what we use on site

It’s a three-wire system on-site; how should it be connected at the cabinet? Are the power negative and signal negative connections made via jumpers?
