Don't have the RCM or any controls. They were removed and replaced with Whelen controls, then those were removed when the siren was decommissioned. All that's left in the control box is a red Whelen sticker and some wires and what looks like a step down transformer of some sortCDV777-1 wrote:The only thing that would be 440 is the blower and rotator motor. And those would just have the motors wired for 440. The chopper will be a regular old thunderbolt chopper. It would be interesting to see the rcm that came with it. The chopper transformer should be different in a 440 rcm.
