Making it last 5 seconds would just be useless. Make it more realistic and have the siren last about a minuteHow about a maxium of one use per round that lasts for 5-10 seconds? It could perhaps be useful to warn reds from the last guard with mini crits or unknown rebels. If guards doesn't listen to the warden, then they shouldn't be in blue to begin with. A lot of pros and cons, the question is which overweights more?
