Are there any smoke detector that are hardwired but communicate wirelessly? My current smoke detectors are all hardwired (120v) and would love to find some that can be wired to 120v but communicate via PowerG, 319.5mhz, or maybe Zwave to the IQ4.
No, an AC power smoke detector that transmits to the panel itself does not exist, however the product linked below can be installed close to one of those interconnected smoke detectors to monitor the whole circuit and report to the panel.
