- Company Profile:
Established in 1896, NFPA's mission is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training, and education.
A device that contains multiple sensors that separately respond to physical stimulus such as heat, smoke, or fire gases, or employs more than one sensor to sense the same stimulus. A device capable of generating multiple alarm signals from any one of the sensors employed in the design, independently or in combination. The sensor output signals are mathematically evaluated to determine when an alarm signal is warranted. The evaluation can be performed either at the detector or at the control unit. This device has listings for each sensing method employed.

A device that contains multiple sensors that separately respond to physical stimulus such as heat, smoke, or fire gases, or employs more than one sensor to sense the same stimulus. This sensor is capable of generating only one alarm signal from the sensors employed in the design either independently or in combination. The sensor output signal is mathematically evaluated to determine when an alarm signal is warranted. The evaluation can be performed either at the detector or at the control unit. This detector has a single listing that establishes the primary function of the detector.
Industry:Fire safety
A device that continually senses for lack of movement of the wearer to automatically activate the alarm signal indicating the wearer is in need of assistance. The device can also be manually activated to trigger the alarm signal.
Industry:Fire safety
A device that continuously monitors the electrical system voltage and automatically sheds predetermined loads in a selected order to prevent overdischarging of the apparatus’ batteries.
Industry:Fire safety
A device that converts a broadband signal into component voice, audio, video, data, and interactive services signals. The NIU provides isolation between the network power and the premises signal circuits. The NIU may also contain primary and secondary protectors.
Industry:Fire safety
A device that converts data that is compatible with data-processing equipment to a form that is compatible with transmission equipment, and vice versa.

Industry:Fire safety
A device that delivers a large water additive stream and is mounted on a movable support or wheels so it can be transported to the fire scene.
Industry:Fire safety
A device that delivers a large water additive stream and is mounted on a stationary support that either is elevated or is at grade.
Industry:Fire safety
A device that delivers an electric shock through the chest wall to the heart and that requires operation by trained medical personnel.
