What is it.

I thought this would be an old school rate of rise heat detector. I am lost on this gizmo. This is as close a photo I can get. One was on lower floor, another was on 2nd floor hall. Unique feature of house is boiler and whole house fan. Any direction would be apreciated.

No batteries. Those are spring wound and loud as hell. Sat through a sales presentation in 1980.
