About once per year we replace a 200 amp fuse that is associated with the DC power wiring to a Civil Defense Siren. Have since a year or two after installation.
Normal run time for these are three minutes or less on Alerts, fire or unit calls. It does pull the full 200 amps. 400 amps would take the fuse at about 100 seconds.
About a $1200 service call if we have to get a lift up there to inspect the motor itself. We will meg it from the controller up today or tomorrow, but I would hazard a guess we've done it before.
Any thoughts?
