Finding the Best Fire Alarms and Sensors

Certain tips need to be considered when choosing a fire alarm. The types of fire alarms or rather smoke detectors include; dual sensor alarms, photoelectric and ionization. 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. The kinds of fires that create a lot of smoke with or without many visible flames is smoldering fires and is detected by photoelectric alarms. Setting of the photoelectric alarm can be done through build-up of dust in the fire unit.

Small particles of smoke from fast flaming fires are detected using ionization alarms. In comparison to smoldering fires, fast, flaming fires produce small smoke 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. Thus the ionization smoke alarm should not be placed near the kitchen or bathroom.

The last type of smoke alarms is the dual sensor smoke alarms in which they combine ionization and photoelectric sensors into one unit. Delay in alert sounding is resulted in dual sensors as some models require both sensors to go off. 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 buy a fire alarm individuals consider things such as inter-connectability, light alarms, digital carbon monoxide display and silence buttons. Fire alarms are required to have a flashing light as part of the smoke alarm’s warning system for the purposes of those whose hearing is impaired. A fire alarm that has a safety light that provides illumination in the dark is recommended.

In terms of interconnectability, fire alarms are linked to carbon monoxide detectors as when the fire sprouts the alarm is immediately triggered. The levels of a home could be multiple and its important to link carbon monoxide detectors with fire alarms.

Another important tip is that the alarm should have a silence button instead of disabling the whole unit. Sounding of the alarm again can be done when triggered and silence buttons are just temporary measures. The number of silence buttons present on the alarm is not at all affected. Displaying the level and concentration of carbon monoxide is done by digital carbon monoxide detectors.
