For construction professionals, knowing the cost of smoke detectors, including devices, wiring, labor, and permits, is crucial. In Memphis, Tennessee, the cost for standard ionization or photoelectric models ranges from $18 to $40 per unit, while dual-sensor models range from $45 to $70. Hard-wired installations cost $85 to $120 per unit, and smart units range from $110 to $180 per unit. Whole-home packages for a 3-bedroom home range from $450 to $750.
