Important Features of Fire Alarm Systems

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. The technology used in the various kinds of alarms include; photoelectric and ionization technology. 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. Through buildup of dust in the photoelectric alarm fire unit, setting of the alarm is achieved.

Small particles of smoke from fast flaming fires are detected using ionization alarms. This is a big difference compared to smoldering fires that release large particles. 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. The alarm is activated when the smoke enters the chamber and disrupts the current.

A false alarm might be raised when the smoke produced by burnt food or by steam from the shower triggering the ionization smoke alarms. 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. 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.

In order to buy a fire alarm individuals consider things such as inter-connectability, light alarms, digital carbon monoxide display and silence buttons. 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. Its quite important to link carbon monoxide detectors with fire alarms as some home are of multiple levels.

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. 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.
