You can buy smoke in a can .
Arduino engineers hate him/her due to this one small trick......
You won't be able to use the same wiring as the work in entirely different ways - the ones you have are monitored by a control panel (24V DC) of some sort, a residential version is entirely independent but can trigger others on an independent high voltage (120V AC) wiring loop through the way it is wired.
I would get something like this to test it. Be sure to get one (like recommended) that doesn't leave a residue - some of the 'most effective' canned smokes available can leave a residue inside the detector and this can cause problems in the long run. It only takes a very small amount (1-second spray) and then wait for it to process and go into alarm state. Also get a can of compressed air to clear the detector out after the test.
If the one is going off outside of your shower then it may be the wrong type (ionization) or may just be getting old and falling outside of its sensitivity range. The one in your photo is photoelectric which is the best choice for this area. Can you show a picture of the box they are connected to?
