  • smoke alarms

    Although the manufacturers will not volunteer any information....CAN you interconnect smoke alarms from different manufacturers within the same home.? Is there a de facto national standard on the interconnect signal??

    Re: smoke alarms

    I have tested a few different brands and they all seem to put +9 VDC on the interconnection lead for an alarm. This makes sense because during an AC power failure, the 9 volts is the only supply available. I have interconnected 2 different brands (both made by Kiddie) and they work fine with or without AC power.
