Important Features of Fire Alarm Systems

Certain tips need to be considered when choosing a fire alarm. Fire alarms or smoke detectors are of various types which are; photoelectric, ionization, and dual sensor alarms. 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 light onto the light sensor is defracted and reflected upon entering the chamber. 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.

As for ionization smoke alarms they detect small particles typical of the smoke from fast, flaming fires. This is a big difference compared to smoldering fires that release large particles. 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. The alarm is activated when the smoke enters the chamber and disrupts the current.

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. The most unsuitable place for placing an ionization smoke alarm is the kitchen or bathroom.

The smoke alarms that are dual sensors are just the combination of ionization and photoelectric sensors into one unit. Both sensors of some dual sensors are required to go off in order for the alert sound to be detected but they cause delay. However there are other models that only require one sensor to be tripped in order for the alarm to sound but this creates potential for more false 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. Safety lights that provides illumination in the dark are a good recommendation for fire alarms.

Triggering of the alarm immediately is done upon detection of a fire as fire alarms are cross linked to carbon monoxide. 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. The number of silence buttons present on the alarm is not at all affected. The overall home safety is ensured by digital carbon monoxide detectors.
