    Hi Aaron,

    Looks like a plug-in transformer. I seem to recall seeing some of these as a part of the phone system, but I don't know exactly what function they provide.

    Did you unplug it? There is typically information on the underside.

    What is the weird white polygon on the wall? Is that some kind of reflection from the flash?

    Thanks a lot guys!!! Yea the white is an odd reflection from my camera. Should I suggest having this removed ?! No I didn't unplug it because it was screwed into the outlet and I didn't want to damage anything he house was in such piss poor shape

    Definitely don't ever unplug these in case its in use. Its not a defect so no need write it up as one but It's worth excluding any low voltage systems like phones or alarms if you do not plan on testing that system.

    That looks to be the low voltage side, the same rules do not apply to low voltage.

    Sorry for the delayed response. I don't read IN as often.
    This is a transformer for an alarm system.
    Alarm system transformers are secured to the outlet by a screw so that it is not accidentally unplugged.
    The wire/ cable to the transformer is phone cable which is 24 ga wire. It is required to be wired with 22ga or better or 18ga fire rated if connected to fire alarm.
    It is allowed to pass through walls, floors, or ceilings unprotected.

    That is not a cord. it is a cable. Aaron has given good information.

    One or more insulated wires surrounded by an insulating jacket.

    Article 725 might be a place to start. There are tricky little requirements, I believe, such as firestopping chases that are burrowed up through fire barriers.
