Smoke alarms are ingenious devices. They are cheap, but very practical and useful. In the UK, has shown that smoke detectors can save thousands of lives each year, and as such, have been highly recommended as part of a fire safety plan. In fact, the regulatory reform (safety against fire) of 2005 requires that adequate fire fighting and fire detection devices shall be installed and provided in commercial establishments.
Installation some of these within a building or a commercial establishment, especially in areas that are prone to fires, could help you, your employees and customers take appropriate measures in these cases. Since these are easy to install and operate, there really is no excuse why this integral part of a fire safety plan must be neglected. Now let's look at some basic information about these alarms.
How they work?
A smoke alarm is essentially composed two main components: a sensor and an audio device that emits a warning. The energy source could come from a battery or house current. The most common sensor or alarm, ionization detector works by detecting positive and negative ions that enter the chamber. When smoke enters the chamber, particles stick to the ions and neutralize them. In this case, the smoke alarm will feel the drop in current between the plates attract the positive and negative ions and then sounds the alarm accordingly.
What are the types of smoke alarms?
There are many types of alarms available. In general, the area which dictates the type installed necessary alarm. For example, if it is a control room, then Visual alarms could more effectively detect overheating wiring. Meanwhile, kitchens or common work areas, surrounded by smoke alarms could use the heat that are designed to detect smoke beyond of what is normally present in these areas. Today, also alarms for deaf and has three methods shake warning, an alert sound, and an intense strobe light
What are the correct installation procedures?
To do this, you may need to consult a team professionals for the installation is done according to existing regulations included in the Order. In general, however, alarms are placed in the ceiling or wall 6-12 cm below the ceiling. These should not be placed near the air vents.
Does it require maintenance?
Certainly, as with any other equipment, maintenance is essential. According to the Fire Department and the post Home Office reports of fires, 40% of the alarms in residences and businesses not work because of dead batteries. With such high statistics, a simple act of checking the battery regularly can help save lives in the long term. Apart this, there is also a need to clean and vacuum the parties within at least one alarm twice a year to remove contaminants and other particles that could being trapped in time. Finally, if a smoke alarm is more than ten years, then it must be replaced immediately to avoid giving a false sense of security.
