Description

The 2040-DSR is a battery powered smoke alarm that features the Kidde TruSense multi-criteria optical smoke sensor, a discreet micro-profile 4-inch design, and a ten year warranty. 

Why TruSense?

More synthetic materials are being used in homes, and those react differently in fires. Smoke alarm standards have changed, requiring flaming and smoldering polyurethane foam fire tests as well as a "nuisance test" to avoid false alarms from minor cooking mishaps. TruSense technology uses a multi-criteria optical sensor (MCO) with advanced programming to identify real fires from false alarms, such as smoke from cooking sources. The system analyzes smoke particles in the air to determine if the source poses a threat. This advanced sensor technology helps Kidde smoke alarms meet the latest UL 217 detection requirements. 

  • TruSense Multi-Criteria Optical Sensor: Detects various fire types and reduces cooking nuisance alarms

  • 9V Battery Included

  • Discreet Design: 4" micro-profile alarm

  • Three Color LEDs: Receive visual notifications of alarm status:

    • Green: Alarm is operational

    • Amber: Low Battery/unit error

    • Red: Smoke detected

  • Test/Hush® Button: Single button tests alarm circuitry and activates Hush feature to temporarily silence nuisance alarms for up to 10 minutes. End of Unit Life and Low Battery can also be silenced for the first 7 days.

  • Loud, 85 Decibel Alarm: Alerts of danger

  • End of Unit Life Warning: Alerts user the alarm is in need of replacement

  • 10-Year Limited Warranty

Technical Specifications

Model: 2040-DSR
Power Source: 9V Battery
Sensor:  Multi-Criteria Optical
Audio Alarm: 85dB at 10ft
Temperature Range:   40˚F (4.4˚C) to 100˚F (37.8˚C)
Humidity Range: Up to 95% relative humidity (RH), non-condensing
Size: 5.8" in diameter x 1.86” depth
Weight: 0.6 lb
Warranty: 10 year (excluding battery)

Architectural and Engineering Specifications

The 2040-DSR shall include a test button that will simulate fire conditions and cause the unit to go into alarm. This sequence tests the unit's electronics to ensure proper operation. To warn for danger, the alarm shall have a piezoelectric horn that is rated at 85 decibels at 10 feet. In a smoke incident, the horn will sound in the repetitive manner - three (3) beeps, a pause, three (3) beeps, a pause.

The alarm shall include an End of Life Unit Alert, where ten years after initial power up the unit shall chirp two times every 30 seconds to indicate the alarm needs to be replaced. This alert can be temporarily silenced in 24 hour increments for seven days.

The unit shall at a minimum meet the requirements of UL217 8th Edition, NFPA 72, NFPA101 (One and two family dwellings), Federal Housing Authority (FHA), Housing and Urban Development (HUD). The alarm shall be UL Listed and shall include a 10-year manufacturer's limited warranty.

Industry experts recommend specific locations for smoke alarms, such as every level and sleeping area of the dwelling. See user guide for more location information.

For maximum detection of the various types of fires that can occur within the home, including fast flaming and slow smoldering, it is recommended that multi-criteria smoke alarms be installed. This model meets the latest residential smoke alarm standards, which includes enhanced resistance to nuisance alarms by cooking.
