Sensor Detector Product Descriptions

First Alert SA320CN Dual Sensor Battery-Powered Smoke and Fire Alarm

Utilizes both ionization and photoelectric smoke sensors for optimal performance.

Intelligent sensing technology reduces non-emergency or nuisance alarms.

Operates on 2 AA batteries (included).

Detects both flaming and smoldering fires with dual sensors.

Emits a loud 85 dB alarm for ample warning.

SA320FF designates SA320CN package in Frustration Free packaging with UN2911 labels for ion smoke alarms.

While all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. This alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning--regardless of the type of fire. Sometimes a fire can smolder for hours before erupting into flames. Photoelectric Sensing Technology is more sensitive than Ionization Sensing Technology at detecting these sorts of smoldering fires, like those caused by cigarettes burning in couches or bedding. Other fires erupt into flames quickly, like kitchen grease fires or fires fueled by paper burning in a wastebasket. Ionization Sensing Technology is generally more sensitive than Photoelectric Sensing Technology at detecting these sorts of flaming fires.

Kidde Battery-Operated Combination Smoke/Carbon Monoxide Alarm with Voice Warning KN-COSM-BA

Smart 2-in-1 Voice Alarm - Voice announces "Fire!" or "Warning! Carbon Monoxide".

Smart Hush - Nuisance alarms are silenced by pressing the hush button..

Battery Safeguard with Front Load Battery Door - Quick and easy battery replacement..

Test/Reset Button, LEDs, and Low Battery Warning.

Meets Underwriters Laboratories (UL) UL2034 and UL217 compliance..

The Kidde KN-COSM-BA battery-operated carbon monoxide and smoke alarm combines two important safety devices into a single unit.

This alarm includes a voice warning system that makes four announcements: fire, carbon monoxide, low battery, or smart hush activation. The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This unit uses three AA batteries, protecting you and your family even during a power outage. This alarm uses ionization-sensing technology for the smoke alarm. Ionization-sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric-sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help ensure maximum detection of the various types of fire that can occur within the home.

KN-COSM-BA Battery-Operated Combination Smoke and CO Alarm at a Glance Employs both smoke and carbon monoxide sensors Stand-alone battery-operated alarm is easy to install throughout the home, as no wiring is needed Features a hush button to silence the alarm for non-emergency situations like a smoky dinner Voice alarm eliminates confusion and clearly warns of smoke/CO danger or low battery Protects from two different hazards, smoke and carbon monoxide, and has a different voice warning for each hazard.

The battery-operated KN-COSM-BA offers easy installation.

Combination Smoke/Carbon Monoxide Alarm The Kidde combination carbon monoxide and smoke alarm includes a voice warning system that eliminates confusion and clearly warns you and your family of a smoke or carbon monoxide (CO) danger, of low battery, or of hush-mode setting.

Alarm Warnings Fire:

The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message: "Fire! Fire!" The alarm will repeat the pattern until smoke is eliminated.

Carbon Monoxide:

Four short alarm beeps followed by a verbal warning: "Warning--carbon monoxide!" This continues until the unit is reset or the CO is eliminated.

Low Battery:

One chirp followed by warning: "Low battery." The red LED light will flash. This pattern will continue every minute for the first hour. After the first hour, the red LED light will flash once every minute and will be accompanied by the chirp sound. The low-battery warning will only sound once every 15 minutes.

Voice Hush Indication:

"Hush activated" and "Hush canceled" voice announcement. Peak Level Memory: If the alarm had detected a CO level of 100ppm or higher when the test/reset button is pressed, the unit will announce, "Carbon monoxide previously detected" to warn of the CO incident. Trademarked Hush Feature for Convenience By pressing the hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners. This feature desensitizes the alarm for approximately 10 minutes. If the smoke is not too dense, the alarm will silence immediately, the unit will verbally announce, "Hush mode activated," and the green LED will flash every two seconds for approximately 10 minutes.

Reliable Battery Power, Indicator LED, Test Feature and Low-Battery Warning The battery-powered alarm provides continuous protection, even during power outages. Because this alarm only helps protect you if it's working, this unit features a red LED that flashes every 30 to 40 seconds to indicate that it is operating correctly.

For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn. If any form of battery failure is detected, the red LED light will flash and the unit will chirp one time, followed by the warning message, "low battery." This cycle will occur once every minute, and will continue for at least seven days. Seven years after initial power up, this unit will chirp" every 30 seconds.

This is an operational end-of-life feature that will indicate that it is time to replace the alarm. UL 2034, the independent standard applicable to CO alarms, requires CO alarms to have an end-of-life warning. This requirement went into effect in March 2007, meaning any CO alarm manufactured after April 2007 with a UL listing must have this feature. Most states that require CO alarms in residential dwellings mandate that the alarm meet the UL 2034 standard.

The unit measures just 5.75 inches in diameter and 1.7 inches deep, and it features a neutral white finish. It includes tamper-resistant features to deter vandalism or theft. This combination smoke/CO alarm is UL listed, so you can be confident of its quality, and it is backed by a ten-year limited warranty.
