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. These types of alarms use photoelectric and ionization technology. From the sensing chamber at an angle away from the sensor is where the light targets in photoelectric smoke alarms. 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. 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. 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. 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. The most unsuitable place for placing an ionization smoke alarm is the kitchen or bathroom.
The ionization and photoelectric sensors are combined into one unit to result to dual sensor smoke alarms. Delay in alert sounding is resulted in dual sensors as some models require both sensors to go off. Only one sensor is required to tripped in order to sound the alarm in other models of dual sensor smoke 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. Alarms need to have a flashing light as part of the smoke alarm’s warning system for the purposes of those whose hearing is impaired. Safety lights that provides illumination in the dark are a good recommendation for fire alarms.
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. However even by having the silence button, upon triggering of the alarm it 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.
