Helios' Deconstructor and noise

[Demotros]

As this weapon functions as a melee(based on mod options), any chance it can be altered from Alarming to Silent? 

[Omega-Shadowblade]

Its probably alarming due to the fact that sentinels don't attack unless enemies are alert anyways. That and its still a gun. It functions like a glaive, but it's still loudly firing a part of itself.

[More-L]

Fairly certain it is in-fact silent, never noticed it alert other enemies when it manages to fire off a shot. Direct copy paste from wiki: 

• It is considered a Melee weapon and although the projectile makes sound, it is actually Silent, and therefore does not alert enemies.

Also keep in mind that melee weapons (including glaives) make a noise when they hit the environment.
