I want to run an AC interconnected smoke alarm system while I have the wall above my panelboard opened up. What's a reasonable/affordable brand? I will probably have a heat sensor in the Kitchen and smoke sensors in the hall way and each of the bedrooms. I've got two old units which I will remove. One is a CO sensor which I no longer need since my furnace is now in the attic. The other is a very old AC smoke sensor.
