    Study Notes

    Approved Monitored Battery Power Smoke Detectors

    • Requires an audible trouble signal at least once every minute for seven consecutive days before the battery can no longer power the device.
    • Alarm signal must operate continuously for at least four minutes.
    • Trouble signal must work for a minimum of seven days after the initial alarm period.
    • Monitored batteries must be clearly identified near the battery compartment.

    Approved Primary Power Smoke Detectors

    • Activated by a source of alternating current electric power.
    • Power supply must be capable of operating the alarm signal for at least four continuous minutes.
    • Installation must comply with the Massachusetts Electrical Code.

    Common Hallway Definition

    Separate Sleeping Areas

    • Areas where people sleep, excluding spaces divided by bathrooms, are considered separate sleeping areas.
    • A bedroom separated from another by a living room is defined as a separate sleeping area.

    Compliance with Massachusetts Electrical Code

    • Approved primary power smoke detectors must adhere to the entire Massachusetts Electrical Code.

    Audible Trouble Signals

    • The minimum duration for the audible trouble signal in monitored battery power smoke detectors is seven days.
    • Audible trouble signals should occur once every minute.

    Specifications of Smoke Detectors

    • The unit must produce an alarm signal for at least four continuous minutes at the trouble signal battery voltage.
    • Specifications of monitored batteries must be indicated near the battery compartment.

    Power Connection Requirements for Smoke Detectors

    • Approved primary power smoke detectors must be permanently wired to a source of alternating current electric power.
    • Cords used to connect to power sources should be underwriter's laboratory approved with a strain relief and plug retainer.

    Common Hallway Reiteration

    • A common hallway is distinctly a space that provides access to required exitways of residential buildings or structures.

    Non-Separate Sleeping Areas

    • A bedroom connected directly to another bedroom or separated by a bathroom is not considered a separate sleeping area.
