Finding the Best Fire Alarms and Sensors

Certain tips need to be considered when choosing a fire alarm. Dual sensor alarms, photoelectric and ionization are the types of smoke detectors. Photoelectric and ionization technology are the kinds of methods used in the various kinds of alarms. Photoelectric smoke alarms use light as the main source which is aimed into sensing chamber at an angle away from the sensor. The alarm is triggered when the light enters the chamber through defraction and reflection. When smoldering fires occur, photoelectric alarms are the used to detect these kinds of fires. Through buildup of dust in the photoelectric alarm fire unit, setting of the alarm is achieved.

As for ionization smoke alarms they detect small particles typical of the smoke from fast, flaming fires. Large smoke particles are produced by smoldering fires while small smoke particles are produced by fast, flaming fires. Ionization alarms use the working principle of holding a small amount of radioactive material between two electrically charged plates that ionizes the air and creates a current between the plates. When the smoke enters the chamber it disrupts the current and activates the alarm.

In addition to the small particles of smoke that is produced by fast flaming fires, ionization smoke alarms can be triggered by the smoke produced by burnt food or by steam from the shower resulting to a false alarm. Either the kitchen or the bathroom are the most unsuitable areas for placing an ionization smoke detector.

The last type of smoke alarms is the dual sensor smoke alarms in which they combine ionization and photoelectric sensors into one unit. Some dual sensor models require both sensors to go off which delays on alert sounding. Only one sensor is required to tripped in order to sound the alarm in other models of dual sensor smoke alarms.

In order to invest on a fire alarms, things such as digital carbon monoxide display, silence buttons and interconnectability are considered. People who have hearing impairment, all fire alarms need to have a flashing light. Some even though not all fire alarms have safety light that provides illumination in the dark.

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.

Instead of disabling the whole unit of the alarm there should be a silence button. However even by having the silence button, upon triggering of the alarm it will sound again. There is no restriction on the number of silence buttons present on the alarm. As for digital carbon monoxide detectors they are important for the home’s safety and display the level and concentration of carbon monoxide.
