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
- Defined as a corridor or space separately enclosed that provides common access to required exitways of the building.
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.
