BlitzBiker2001's Vintage Simplex Collection

It’s been a long while since I’ve posted an updated collection, so I figured I would show just the Simplex devices in my collection since that’s what I like most. I’ll eventually make a post about my non-Simplex devices. Now since part of my collection is in storage, I’ll have to group pictures of similar devices since they can’t be displayed together. I should also note that nothing from my collection is for sale, I’ve worked really hard to get where I am.

Notification Appliances

Simplex 2903 Family

16x Simplex 2901-9838 on Simplex 2903-9001’s
I have quite a few 9838’s on 9001’s. All but one of these came from a Simplex 4002/4005 system at an elementary school I attended from 2011-2013, and I often dreamed about removing these to have for my collection. Though I didn’t personally removed them I’m still happy to have a piece of my childhood.

2x Simplex 2901-9833 on Simplex 2903-9102 w/ 1 back box. I got these from the electrical program I attended during high school. My old teacher said they were donated by a security company over 20 years ago. Interestingly one of the 9833’s has pigtails instead of terminals.

This came from the same 4002/4005 system that all those 9838’s on 9001’s came from, which you’ll see more parts of the system later.

That’s my collection as of 8/13/23. I’m still on the lookout for a Simplex 2001, and a Simplex 4208, as well as any more older bilingual pulls, and different varieties of pull stations.


Very cool devices! ( I need to get some simplex stuff )

Man you’ve got a lot of stuff! (a lot of cool & rare stuff no less) You have got to have the most 2903 plates of any collector I know!
