Fire Alarm

A fire alarm system is designed to detect unwanted presence of fire by monitoring changes in pressure and air temperature within your home.  There are two types of fire alarms; automatic and manually activated.  Automatic systems are used to sense and notify individuals to evacuate from a building in the event of a fire, as well as to summon emergency service.  Manually activated systems are used by individuals who are wishing to notify an entire building when they see a fire, these systems also summon emergency services.  Manually activated devices; Break glass stations, Buttons and manual pull station are constructed to be readily located (near the exits), identified, and operated.  Automatic systems are the most popular and usually only businesses or large buildings have manually activated systems.  Automatically activated devices can take many forms intended to respond to any number of detectable physical changes associated with fire: confected thermal energy; heat detector, products of combustion; smoke detector, radiant energy; flame detector, combustion gasses; carbon monoxide detector and release of extinguishing agents; water-flow detector. The newest innovations can use cameras and computer algorithms to analyze the visible effects of fire and movement in applications inappropriate for or hostile to other detection methods.

The fire alarm control panel in your home is the main component of your alarm system in monitors inputs and relays information.  The primary power supply is commonly a 120 volt source that is supplied by the building’s main power line.  In case of a power outage or other emergency all systems have a secondary power supply which is usually a battery but in some cases is a generator.  Initiating devices are located throughout the residents and act to input information collected about the temperature and pressure ratings of the area.  Notification appliances activate a loud, high pitched indicator that there is a problem with in the building.  Many high-end alarm systems will display the area of concern on the systems control panel.

Audible, visible, tactile, and even textual notification are used to alert the occupants and home owners when an alarm is sounded.   Audible or visible signals are the most common and may use speakers to project  live or pre-recorded instructions to the occupants. In the United States, fire alarm evacuation signals are required to use a standardized interrupted four count temporal pattern to avoid confusion with other signals using similar sounding appliances.  Audible and textual notification, which are sent in higher scale fire alarm systems called Emergency Voice Alarm Communication. High reliability speakers are used to notify the occupants of the need for action in connection with a fire or other emergency. system may be controlled from one or more locations within the building known as Fire Wardens Stations, or from a single location designated as the building Fire Command Center. Speakers are automatically activated by the fire alarm system in a fire event, and following a pre-alert tone, selected groups of speakers may transmit one or more prerecorded messages directing the occupants to safety. These messages may be repeated in one or more languages. Trained personnel activating and speaking into a dedicated microphone can suppress the replay of automated messages in order to initiate or relay real time voice indicators.

Having a fire proof gun safe or fire proof safe is extremely important for all your irreplaceable documents, pictures, or paper money. They are fairly inexpensive, depending on the style and brand, just keep in mind, you usually get what you pay for, and when protecting your valuables, quality counts.
