fire safety

Please tell me if the following phrases, about a fire safety system in an office, sound OK to you. Thanks!

"All office premises must be equipped with a sufficient number of smoke detectors, linked up together with ??cables to form a ??chain. The cables must be connected to a central switchboard.
...All office premises must be equipped with special tubes (pipes?) with snouts (muzzles?) for gas supply. The tubes (pipes?), in turn, must be connected to an installation (unit? rack?) (equipped) with gas containers holding incombustible gas (usually СО2 is used)."

P.S. The picture of "special tubes (pipes?) with snouts (muzzles?) for gas supply"
