Smoke detectors are also known as smoke alarms or smoke sensing devices. A smoke alarm works by monitoring the concentration of smoke to prevent fires. It uses an ionization smoke sensor, a technologically advanced, stable, and reliable sensor that is widely used in various fire alarm systems. Its performance is far superior to gas-sensitive resistive fire alarms.
UL217 specifies the performance, reliability, and safety requirements for fire alarm devices, providing an important basis for protecting lives and property. The main content includes the classification and types of fire alarms, performance indicators (such as sensitivity, response time, false alarm rate, etc.), and reliability requirements.
Smoke Detectors: Smoke detectors can emit audible or visual alarms in a specific area to indicate the presence of smoke and potential fire danger. These products are typically used in homes.
Smoke Sensors: Smoke sensors are part of large fire safety systems that send signals to fire alarm control panels, notifying of smoke and potential fire danger in a specific area. These products are generally used in commercial environments.
Carbon Monoxide Detectors: Carbon monoxide detectors emit an audible alarm before the carbon monoxide concentration reaches dangerous levels. These detectors are designed to detect sources of carbon monoxide, such as internal combustion engines, faulty fuel equipment, and fireplace exhaust systems (but not limited to these).
Home Gas Detectors: Home gas detectors are used to detect flammable gases in the home, such as propane and natural gas.
