Sensors and Fire Alarms For Safety Uses

For the purposes of choosing a fire alarm there are certain tips that need to be considered. Fire alarms or smoke detectors are of various types which are; photoelectric, ionization, and dual sensor alarms. These types of alarms use photoelectric and ionization technology. Smoke alarms that are photoelectric use light as the main source which is aimed into sensing chamber at an angle away from the sensor. Upon entering the chamber the light is defracted and reflected onto the light sensor which triggers the alarm. When smoldering fires occur, photoelectric alarms are the used to detect these kinds of fires. When there is buildup of dust in the photoelectric alarm the alarm is set off easily.

Small particles of smoke from fast flaming fires are detected using ionization alarms. Large smoke particles are produced by smoldering fires while small smoke particles are produced by fast, flaming fires. The working of ionization alarms is that it holds a small amount of radioactive material between two electrically charged plates that ionizes the air and creates a current between the plates. Upon entering the chamber, the smoke disrupts the current and activates the alarm.

A false alarm might be raised when the smoke produced by burnt food or by steam from the shower triggering the ionization smoke alarms. Either the kitchen or the bathroom are the most unsuitable areas for placing an ionization smoke detector.

The ionization and photoelectric sensors are combined into one unit to result to dual sensor smoke alarms. Some dual sensor models require both sensors to go off which delays on alert sounding. Some models in smoke alarms only require one sensor to be tripped in order for the alarm to sound but this creates potential for more false alarms.

Inter-connectability, light alarms, digital carbon monoxide display and silence buttons are some of the concerns when wanting to invest on a fire alarm. People who have hearing impairment, all fire alarms need to have a flashing light. A fire alarm that has a safety light that provides illumination in the dark is recommended.

When it comes to interconnectability, linking of carbon monoxide to the fire alarm is done upon rise of a fire. Homes that are of multiple levels need to define this clearly that is the linking of carbon monoxide detector to the fire alarms.

Another important tip is that the alarm should have a silence button instead of disabling the whole unit. A silence button is a temporary measure and when the alarm is triggered the alarm will sound again. Silence buttons present in a fire alarm is not a factor of concern. As for digital carbon monoxide detectors they are important for the home’s safety and display the level and concentration of carbon monoxide.
