Early Sterling sirens that resembled Denvers

Sat Jul 07, 2018 6:19 pm

Attached are some articles from a siren built by Interstate Machine Products for Sterling Siren Fire Alarm of Rochester NY. Whether the patent for the Denver Siren was bought out or Sterling just designed a similar siren is t be determined. A few of the Duplex single head models have been found in the wild, but I don't think we've ever found a dual head quadruplex.

Are you sure that's not just a Y-10 with no shroud?

I think his well researched post makes him pretty dadgum sure. Go look at a photo of a Y-10. I think that will make you sure, too.

A Y 10 is nothing more than an M style siren with a coding brake.

I think the actual rotor/stators on these are Denver products. Sterling may have sold them paired to motors as their own, or on behalf of Denver. Note the term "Quadruplex" on the advertisement. That is definitely a Denver term, not Sterling's.

See I'm almost wondering if it wasn't a new design for the Denver that was sold to Interstate Machine by Dillon Box Iron Works inorder eliminate sirens from their product line.

Could that possibly be a prototype Quadruplex, just adding on shrouds simmilar to that of a Sterlng M??
