Recommended Locations for Smoke Alarms
The Kidde i12040a smoke alarm should be installed in strategic locations to maximize fire detection effectiveness. Place the first alarm near bedrooms to monitor exit paths. Additional alarms should be installed in each sleeping area, stairways, and every floor level. For optimal coverage, mount alarms on ceilings or walls, ensuring they are at least 4 inches from walls and 4 to 12 inches below ceilings. In mobile homes, avoid thermal barriers by installing on inside walls if necessary. Avoid areas near kitchens, bathrooms, or high-moisture spaces to reduce nuisance alarms. Ensure alarms are within 3 feet of the peak on sloped ceilings and follow NFPA guidelines for spacing in large rooms or hallways. Proper placement ensures reliable detection and safety.
Step-by-Step Wiring Instructions
For safe and proper installation of the Kidde i12040a smoke alarm, follow these wiring steps:
Turn off the main power supply to the circuit before starting.
For single-station use, do not connect the red wire; leave it insulated.
In interconnected systems, ensure all units are powered from a single circuit.
Connect the black (hot) and white (neutral) wires to the corresponding terminals.
Use a UL-listed junction box and ensure wiring complies with local electrical codes.
The interconnect wire resistance must not exceed 10 ohms.
For multiple units, interconnect wiring should be in the same raceway as the AC power wiring.
Avoid using square wave or modified sine wave inverters, as they can damage the alarm.
Ensure the power source is 120V AC, single-phase, from a non-switched circuit.
Consult a qualified electrician if unsure about any step.
Interconnecting Multiple Units
The Kidde i12040a supports interconnectivity with up to 24 Kidde devices, enhancing whole-home safety. For proper interconnection:
– All units must be powered from a single circuit.
