    The First Alert Cat. No. SA340B is a battery operated, 9V (three 3V lithium power cells) single station smoke alarm specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories and other multi-family dwellings as defined in standard NFPA 101. Model SA340B complies with UL217, CSFM, NFPA 72, HUD, FHA and other agencies that model their codes after the above agencies. It meets building codes where tamperproof 10-year sealed lithium battery operated smoke alarms are required.

    First Alert SA340B features a dual ionization smoke sensing chamber, an 85 dB horn, a sealed 10-year lithium power cell power supply that is permanently installed upon activation of unit, a single button for test/ silence and a red LED that blinks to indicate unit is receiving power. The tamperproof design will not allow the powercells to be removed after installation. The low power warning indicator will cause the alarm to "chirp" when it reaches the end of its service life and needs to be replaced.

    Upon end of life, the unit meets UL requirements for disabling the alarm and non-reinstallation of unit to mounting bracket.

    Designed for surface mounting, the SA340B includes mounting anchors and screws. Includes a gasketless base for easy installation and a new mounting bracket that keeps the alarm secure over a wide rotation range to allow for perfect alignment. Pins are provided to lock unit to mounting bracket and to prevent removal and theft of unit.

    Dual Ionization sensing chamber. Generally more effective at detecting small particles produced by flaming fires. Sources may include paper or kitchen grease.
    10 years of continuous protection.
    Powercell cannot be removed after installation.
    Alarm will chirp when it reaches the end of its service life and needs to be replaced. LOCKING FEATURE Pins are provided to lock alarm to base. Great for apartment, dormitory or hotel applications where unauthorized removal of alarm is not desired.

    The SLR-24V can be used in all areas where Photoelectric

    Smoke Detectors are required. The wide range

    smoke chamber makes the SLR-24V well suited for fires

    ranging from smoldering to flaming fires.

    NS-4 Series, NS-6 Series, HSC-4R or HSC-xxx R Style

    bases may be used with the SLR-24V. Current

    interchangeable/compatible devices are the SIJ-24

    ionization detector, the SLR-24H photoelectric detector

    with heat sensor, and the DCD-135/190 heat detectors.

    All NS conventional devices are mechanically

    compatible with Hochiki America HSB, HSC and YBA

    type bases which may have been used in previous

    installations. Please check individual panel listings for

    compatible bases.




    The SLR-24V photoelectric smoke detector utilizes two

    bicolored LEDs for indication of status. In a normal

    standby condition the LEDs flash Green every 3 seconds.

    When the detector senses that its sensitivity has

    drifted outside the UL listed sensitivity window the LEDs

    will flash Red every 3 seconds. When the detector

    senses smoke and goes into alarm the status LEDs will

    latch on Red.

    The detector utilizes an infrared LED light source and

    silicon photo diode receiving element in the smoke chamber.

    In a normal standby condition, the receiving element

    receives no light from the pulsing LED light source.

    In the event of a fire, smoke enters the detector smoke

    chamber and light is reflected from the smoke particles

    to the receiving element. The light received is converted

    into an electronic signal.

    Signals are processed and compared to a reference level,

    and when two consecutive signals exceeding the reference

    level are received within a specified period of time,

    the time delay circuit triggers the SCR switch to activate

    the alarm signal. The status LEDs light continuously

    during the alarm period.
