At 3:30 am a couple days ago, the smoke detectors went off. Not the 'low battery' noise, but full alarm triggering the others to sound off as well. I checked around, and with no actual issue, pulled them all off. 6:00 visit to Home Depot. Turned off the breaker, took my meter to verify dead wires, and started replacing them, 6 total. The alarms came with wiring adaptors which were mostly fine. In 2 cases, there was already such a rat nest of wiring that I had to just use the actual wire and skip the adaptor to save space.
In this box, there was more than just connectors. And my question. Can anyone identify this? I have 3 floors, basement/first/second, and this was in the box on the first floor with a 4th connector. Other boxes had a lot of wire, but it looked pretty standard, in/out, and alarm. (And yes, crappy installation, that box is loose, but tight after putting mounting plate on.)

I'm going to go with... It's a smoke/heat/CO alarm relay. There are many different types and they all look different. This is quote from the Kiddie website "This module is only activated by a smoke alarm interconnect signal. The relay portion of this module can be used to activate auxiliary warning devices such as external bells and sirens, hallway or stairwell lighting. It provides isolated, (no internal connection to 120 volts AC) normally open, and normally closed contacts"
