I know I've done this before but for some reason I am stuck. I have a smoke alarm where the battery compartment is being blocked by the permanent power. I can't disconnect or a monitoring alarm will trip (i think?). There is a great deal of tension here and any more force I feel will break the connector. So how do I open the battery area here?

Can you see an indication of the brand and model number - to look on-line for instructions?

Squeeze the sides (clips) of the plug and remove it from the back of the detector. Replace the battery. Reinstall the plug - it should just push in. Reinstall the smoke detector in the ceiling.
 
If it continues to beep or chirp every 1 minute after replacing the batteries, then you may have a defective unit that needs to be replaced.
 
At this time I'm going to try removing the two alarms from power, removing the battery and holding the test button for 15 seconds and killing the circuit breakers for the rooms
 
What a bad design. Mine have a little slide open door on the outside, no need to open the detector.

They may need cleaning in addition to new batteries. We've had the same alarm go off because of dust or fiber accumulation. Using a vacuum cleaner to draw out the foreign material worked.

Water heater hiding in a closet off the bathroom?
There was one breaker I didn't kill and that was for the washer and heater because there was a danger sticker and it needed some key to turn off.
 
This is the intermittent "beep/chirp" for low battery, not the "wake the dead/get out now" end of the world alarm noise? Check the area around the washer and heater for a hidden unit --- I've had a couple that the battery lasted for nearly a decade before the chirping started and took me literally forever to find.
 
Murphy's Law: something that requires the landlord or super is always going to happen after hours. Get the aeroduster and try A-nuc's cleaning trick. I'm out of ideas where to find a third alarm, and if that doesn't work, hope the landlord still has enough specs on the building to fix things.
 
After more thinking I don't think it has anything to do with my detectors. The wall mic is connected to the fire panel downstairs. I think either the mic is broken or something with the panel is setting it off.

What's a "mic"?
[edit]
The model number is readable in your pic: http://www.thesignalsource.com/documents/GX93.pdf
It's a remote horn (speaker) for a building-wide evacuation from the master building alarm panel. It doesn't have a battery backup.

I'm glad Russ asked. I've just been assuming it's what dlgoff has just informed us it is --- the anunciator to inform residents that someone else is trying to burn down the building.

If you missed my edit, I found the data sheet for the annunciator -- it doesn't have a battery backup or a "chirp" mode. If it is making noise and it isn't blasting you out of the house, something is wrong with it or the building alarm system.

Since it is just a speaker, it shouldn't ever need to be replaced. There isn't anything in it that can wear out.
