Finding the Best Fire Alarms and Sensors

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. These types of alarms use 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. Upon entering the chamber the light is defracted and reflected onto the light sensor which triggers the alarm. Alarms that are photoelectric are used to detect smoldering fires as they create a lot of smoke with or without many visible flames. 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. 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. 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.

Inter-connectability, light alarms, digital carbon monoxide display and silence buttons are some of the concerns when wanting to invest on a fire alarm. 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. Homes that are of multiple levels need to define this clearly that is the linking of carbon monoxide detector to the fire alarms.

A silence button is required of an alarm when planning to buy one. A silence button is a temporary measure and when the alarm is triggered the alarm will sound again. Silence buttons present in a fire alarm is not a factor of concern. The overall home safety is ensured by digital carbon monoxide detectors.
