Recently this Grifco 888 was refurbished and received an overhaul with its motor and had a newer version housing put in. This was probably the loudest siren I’ve heard so far! The last siren test being Cessnock, the 888 struggled to run at full power hence making it more quiet. Anyways, this was Lightningfun64’s first time hearing a siren go off!
