Three safety functions in one alarm
One device provides smoke detection, CO detection and a synchronized visual strobe, reducing the need to coordinate separate detection and visual-notification products.
The Kidde P4010ACLEDSCOCA-2 combines smoke detection, carbon monoxide detection, voice warnings and a bright 177-candela LED strobe in one low-profile, 120 V AC hardwired alarm. It includes a sealed 10-year lithium backup battery for the smoke and CO alarm functions and is designed for compatible interconnected Kidde alarm systems.
This model is designed for projects that need combined smoke and carbon monoxide detection together with visual and voice notification. It is particularly relevant where the approved project design calls for a hardwired alarm with an integrated high-intensity strobe.
One device provides smoke detection, CO detection and a synchronized visual strobe, reducing the need to coordinate separate detection and visual-notification products.
The integrated Cree® LED strobe provides visual warning and can synchronize with compatible P4010ACLEDSCA and P4010ACLEDSCOCA-series strobe alarms.
The alarm connects to 120 V AC power and includes a sealed 10-year lithium backup battery for the smoke and carbon monoxide alarm functions.

Ontario smoke and carbon monoxide alarm requirements depend on the building type, construction date, renovation scope, fuel-burning equipment, attached-garage conditions, approved plans and the authority having jurisdiction.
Ontario public guidance requires working smoke alarms on every storey and outside all sleeping areas in homes. New construction or renovation projects may have additional hardwiring, interconnection and location requirements.
From January 1, 2026, affected Ontario homes and residential units require CO alarm coverage adjacent to sleeping areas and on every storey, including storeys without sleeping areas.
The 177-candela strobe may support a visual-signalling design where visual notification is required, but product selection alone does not establish complete Building Code compliance.
Read the complete Ontario Smoke & Carbon Monoxide Alarm Code Guide for placement, 2026 CO-rule, visual-signalling and replacement guidance.
Suitable for consideration in new homes, additions and permitted renovations where the approved plans specify combined smoke, CO, voice and visual notification.
The integrated visual strobe is designed to provide visual warning for deaf and hard-of-hearing occupants, subject to the approved project design and placement.
Useful where a compatible hardwired Kidde interconnected system is already specified. Verify every existing model before adding or replacing an alarm.
Both models provide a hardwired 177-candela visual strobe and voice warning, but only P4010ACLEDSCOCA-2 independently detects carbon monoxide.
| Feature | P4010ACLEDSCOCA-2 | P4010ACLEDSCA |
|---|---|---|
| Smoke detection | Yes | Yes |
| Carbon monoxide detection | Yes | No |
| 177-candela LED strobe | Yes | Yes |
| Voice warning | Yes | Yes |
| 120 V AC hardwired | Yes | Yes |
| Sealed backup battery | Smoke and CO alarm functions | Smoke alarm function |
| Best suited for | Combined smoke, CO and visual notification | Smoke and visual notification only |
This page's model provides independent smoke and carbon monoxide detection along with the 177-candela visual strobe and voice warnings.
The 2-in-1 model provides smoke detection and visual notification but does not independently detect carbon monoxide.

Do not assume every Kidde-branded alarm is compatible. Check the model numbers of every alarm connected to the same interconnect circuit.
Fixed wiring must comply with applicable electrical requirements and should be completed by a person authorized to perform the work.
