120V AC/DC Wire-in Low Profile Smoke Alarm	Part Number 21007288
Sealed Rechargeable Battery Backup	Model KN-SMFM-i
Sealed Rechargeable Battery Backup

Architectural and Engineering Specifications

The smoke alarm shall be Kidde model KN-SMFM-i or approved equal. It shall be powered by a 120VAC, 60Hz source along with a rechargeable bat- tery backup. The unit shall incorporate an ionization sensor with nominal sen- sitivity of .50 to .98%ft. The temperature operation range shall be between 40˚F and 100˚F (4.4˚C and 37.8˚C) and the humidity operating range shall be up to 85% relative humidity.

The smoke alarm can be installed in standard junction boxes listed below. The electrical connection (to the alarm) shall be made with a plug-in connector. A maximum of 24 Kidde devices can be interconnected in a mul- tiple station arrangement. The interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18 initiation devices, of which

12 can be smoke alarms. With 18 initiating devices (smoke, heat, CO, etc.), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules.

The alarm shall include a test button that will electronically simulate the presence of smoke and cause the unit to go into alarm. This sequence tests the unit’s electronics, battery and horn to ensure proper operation.

The unit shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. Single button operates both Smart Hush™ and alarm test for easy opera- tion and less confusion. The unit shall also include a low battery warning utiliz- ing a brief alarm chirp every 60 seconds for a minimum of seven (7) days.

The unit shall incorporate red and green LED indicators. The green LED indicates the status of the alarm. The red LED is a visual indicator of alarm and warning chirps.

Standby Condition: The green LED will be lit if on AC power or blink once every 30 seconds if on battery backup. Alarm Condition: When the alarm senses products of combustion and enters alarm the red LED will blink in unison with the sounder and the green LED will flash once every

2 seconds. The flashing LEDs and pulsating alarm will continue until the air is cleared. When the units are interconnected, only the green LED of the alarm(s) sensing smoke or is being tested (the originating unit) will flash.

All other units in the interconneced system will sound an alarm and flash the red LED but the green LED will remain at is standby state. Alarm Memory: This smoke alarm is equipped with an alarm memory, which provides a visual indication when an alarm has been activated. The green LED will flash every 16 seconds to indicate the memory condition. Smart HushTM Mode: The green LED will flash every 3 seconds but the alarm will not make any sound, indicating the smoke alarm is in the Smart HushTM Mode.

The unit shall at a minimum meet the requirements of UL217, NFPA72, (chapter 11), The State of California Fire Marshall, NFPA 101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD). It shall also include a 10-year manufacture’s limited warranty.

Installation of Smoke Alarm

The smoke alarm must be installed to comply with all local codes having jurisdiction in your area. All wiring shall be in accordance with articles 210 and 300.3(B) of the US National Electrical Code, ANSI / NFPA 70 and NFPA 72. The multiple station interconnect wiring must be in the same raceway as the AC power wiring. In addi- tion the resistance if the interconnect wiring shall be a maximum of 10 ohms. Make certain all alarms are wired to a single, continuous (non-switched) power line, which is not protected by a ground fault interrupter. A maximum of 1000 ft. of wire can be used in the interconnect system. Use standard UL listed household wire as required by code.

The Kidde KN-SMFM-I is a state-of-the-art smoke and carbon monoxide (CO) alarm designed to protect homes and ensure the safety of occupants. With the rising importance of advanced safety features in modern alarms, the KN-SMFM-I stands out due to its combination of smart technology, user-friendly design, and efficient performance.

One of the main features of the Kidde KN-SMFM-I is its ability to detect both smoke and carbon monoxide. This dual-sensor capability is crucial for comprehensive safety, as smoke and CO are both dangerous yet different threats that can arise in residential settings. The device utilizes advanced sensing technology, combining an ionization sensor for smoke with an electrochemical CO sensor. This diverse sensing method enhances the alarm's ability to accurately identify the presence of threats while reducing the chances of false alarms.

The KN-SMFM-I also includes a voice alert feature, which announces the type of danger detected. This is particularly beneficial in a situation where quick action is necessary, allowing occupants to understand whether there is smoke or carbon monoxide present. The unit offers a loud 85-decibel alarm that ensures it can be heard even in the noisiest of environments.

Moreover, the Kidde KN-SMFM-I is equipped with a Smart Hush feature, allowing users to temporarily silence the alarm during non-threatening situations, such as cooking incidents that may produce smoke. This feature prevents unnecessary panic and supports user engagement with the device.

Another characteristic of this model is its easy installation process. It operates with a battery backup, meaning it continues to function even during power outages, which is essential for maintaining safety at all times. The unit also features a low battery chirp alert, informing users when it's time to replace the batteries, ensuring that the alarm remains operational without unexpected interruptions.

The Kidde KN-SMFM-I is designed with user-friendliness in mind, featuring a sleek, modern aesthetic that blends well with various home decors. Additionally, the device has a test/reset button, allowing users to easily ensure that the alarm is functioning correctly.
