Hello,
This is my first post, my apologies in advance if it is not properly formatted for this forum.
I am replacing the smoke alarms in my house with interconnected units. To be up to local code, they must be hardwired, cable interconnected and must all go off in a unit (this place is a duplex).
This duplex has a shared stairwell, that has its own smoke alarm. The building inspector has told me that this alarm must go off if either unit's alarms go off. To this point, I have just had all alarms connected for simplicity. Last night at around 1:30am, the other units alarms went off, triggering our own to sound. As a solution, I am thinking of wiring in two diodes from each unit to connect to the stairwell unit, without sending the signal to the other unit (see attached drawing). The concern that I have is if there is a fire in the stairwell, the alarm will sound, but will not be able to send out an alarm with the cable to both units, which would be required.
Any thoughts on possible solutions? Any help greatly appreciated.
