I'm busy restoring an old 50's fire alarm siren. It has a brushed motor and was made by Carter (Nelson) Ltd, Lancs England. The manufacturer's plate on it only states "6V ACDC".
When I first got it, it was dirty but the motor's armature was still rotating by hand so I connected my bench powersupply to it, set to 6V but had no reaction as the supply can only handle 3.5A.
I've made some enquiries at another site and they reckon this siren will draw close to 20A and they recommend I run it from a 6V car or motor cycle battery.
Will there be another option other than a lead acid battery?
