Flashbang door traps?

[H u n k]

in ''Sins of the Father'' I triggered a door trap (with no wire visible) and heard the pin drop and a flashbang detonate. never thought that'd be a thing. my guess it's an alarm system for the suspects.

The flashbang will stun players for sure, unless you're wearing anti-flash goggles. But all deployables do have a global alert kind of system. I think it does have a range, but the kit you use and the way you use it does impact things like if they're going to surrender or if they're going to shoot.
