For this request, compare how each proposal handles type of detectors: smoke, CO, or combination, wiring requirements: battery vs. hardwired, and the choice between chirping and nuisance-alarm diagnosis and hardwired alarm replacement. Those scope details matter in addition to the versioned regional market adjustment shown in the planning ranges.
