Hello Bernard.........my name is XXXXX XXXXX I will be happy to assist you with your electrical question. My goal is to exceed your expectations on Just Answer!
1) Is the outlet you are referring to a GFCI receptacle that has a test and a reset button on it?
2) Are all the smoke alarms hard-wired in the ceiling or are any of them battery operated and a wireless type?
Are all of the smoke alarms in the house wired as "inter-communicated"? In other words, if 1 smoke alarm goes off, so do all of the rest of the smokes in the house simultaneously?
3) If the smokes are hard-wired, are they all connected to the same circuit as the GFCI receptacle or only the (1) one smoke is connected?
1) Bernard............if the receptacle is indeed a GFCI type and your smokes are wired to the LOAD side of the GFCI, it is never recommended to have smokes wired to a GFCI due to nuisance tripping and also for safety purposes.
2) A GFCI has 2 wiring connections located on the back of the receptacle, ie, LINE side and LOAD side. If the smokes are wired to the LOAD side screw terminals and the GFCI has been tripped, the smoke alarms will never work on AC voltage and would only work if they are a combo AC/Battery type.
3) Hard-wired smokes typically have 3 wires, ie...... 1 hot, 1 neutral and 1 inter-communicated. The inter-communicated wire is wired to other smokes within the house in a daisy chain fashion. If 1 smoke is triggered, it will send a voltage signal to the remaining smokes and all of them will sound simultaneously. It is very possible that if the smokes are connected to a GFCI LOAD side, the smokes were wired incorrectly and possibly the "inter-communicated" wire was connected to the LOAD side of the GFCI. If you feel comfortable in doing so, you would need to perform a visual inspection as to how things are wired to determine and confirm if this is what is causing the problem. If not comfortable working with electricity or you don't have the proper voltage testing instruments, I would recommend having a licensed electrician check things out.
4) The other outlet in the other room may also be wired as a downstream receptacle off of the same GFCI receptacle on the LOAD side and causing the same problem.
5) I would recommend to remove any smokes wiring in the house and get them off of the LOAD side of any GFCI breakers or GFCI receptacles. They should be re-wired and not on a GFCI device.
Hope this helps.........If you have any additional questions, let me know and I'll be glad to answer them for you.

Just noticed your response, so I will be reading over the great information you gave me. Please see my answers to your questions also.
2) Are all the smoke alarms hard-wired in the ceiling or are any of them battery operated and a wireless type? HARD WIRED
Are all of the smoke alarms in the house wired as "inter-communicated"? In other words, if 1 smoke alarm goes off, so do all of the rest of the smokes in the house simultaneously? IT SEEMS LIKE THEY ARE NOT, FOR WHEN WE PLUG IN SOMETHING WITH THE KITCHEN OUTLET ONE GOES OFF NEARBY, AND WHEN WE PLUG IN THE VACUMM IN THE OTHER THE SMOKE DETECTOR NEAR IT GOES OFF.
3) If the smokes are hard-wired, are they all connected to the same circuit as the GFCI receptacle or only the (1) one smoke is connected? AGAIN, THEY SEEM TO BE CONNTECTED TO THE CIRCUIT THAT IS BEING TRIGGERED BY THE OUTLET NEAR THEM.
1) Thanks for the replies.
2) Since I am located in the United States, I am only familiar with the National Electrical Code and am not familiar with what code the Cayman Islands adheres too. However, since your home is fairly new, I would assume that your smokes are also the "inter-communicated" types since these are very common. But as I mentioned, I'm not certain of the electrical code requirements in the Cayman's.
3) As I mentioned, if the smokes are wired to the LOAD side of a GFCI and/or wired incorrectly with the "inter-communicated" conductor, this can very well be the cause of the problems. The only way to determine if the smokes are the "inter-communicated" type is to temporarily lower each smoke device from the ceiling and look if there are 3 wires. The wire colors will typically be black (hot), white (neutral) and a red or yellow for the inter-communicated conductor.

Bernard........ thank you for the excellent service rating...........much appreciated!
If you have any other questions, let me know.
Take care and have a great evening...........Thanks again............Kevin!
