The sound fire alarm is to warn the people in the facility of a possible danger. The notice will only be activated when there is a fire accident. It can make people come out from their place, even if they feel fear and terrified because the strength of this kind of machine is more muscular than the human voice. However, sometimes we hear about some bad things happening due to false alarms, which wastes time and money for that building owner and raises stress and tension among workers in that company or organization.
Building Fire Alarm Systems – How to Ensure Effective Protection
When the building you are in is on fire, you need help immediately. A properly designed and installed building fire alarm system can save lives by notifying everyone quickly.
Specifically, three stages of reaction must occur for an effective fire protection program:
Fire Detection: The first stage occurs when a potential fire source ignites combustible fuel. A device designed to detect this starts either an audio or visual alarm, depending on the device’s location. This provides occupants with enough time to react before conditions become life-threatening. For example, if the heat sensor detects that the temperature has reached 135 within five minutes, it will cause a flashing red light above the said area with a siren sounding simultaneous. It will continue to display until the temperature has dropped below 135 again.
Timed Fire Suppression: The second stage involves activating suppression systems or equipment that focuses on specific areas of fire growth. Heat detectors activate these devices in the area, which causes an air supply damper to shut down and allow for pressure equalization before introducing water into the room not to blow out any still-burning fires. By introducing suppression elements at critical phases of development, this stage reduces fire development and can almost extinguish it.
Evacuation: The third stage is evacuation, where people are removed from the building immediately after sounding alarms. Specially designed electrical devices monitor if doors are open or closed during a fire event. If they are available, the alarm will sound, which provides an escape route for building occupants.
Fire Protection Systems – Building Construction Considerations
Building codes have strict guidelines to ensure that a structure can withstand dangerous fire conditions long enough for emergency responders to arrive and put out the fire with adequate methods. These codes require that you choose locations of equipment outlets wisely to accommodate their various components during installation. A single outlet must house triggers, detectors, valves, manual pull stations, horns, strobes, and bells, all simultaneously if necessary. You must also pick proper wire types for building construction depending on your electrical load calculations and environmental factors such as exposure to high heat or moisture levels, so it does not become damaged.
In addition, you must consider building construction in your choice of fire alarm control panel placement. This means that the unit cannot interfere with egress through doors or windows in case of a fire. In some areas, you will need to mount this device at least three feet above ground level or is accessible after an evacuation. You can also install it in a secure area away from potential water damage and theft threats.
