Fire detection systems have been included in architectural plans since the early 1900s and now form an integral component of any building structure. Unfortunate fire accidents may occur from various unforeseen reasons and small controllable fire outbreaks can escalate to consume an entire building within a matter of minutes if not detected. Technological advancements have however been of great utility in many sectors including fire detection and alarm systems. These technologies are able to identify conditions that are likely to induce fire outbreak including smoke, heat and water.
A fire detection and alarm systems basically refers to electronic equipment designed to detect presence of fire or smoke and relay an alarm both in audio and visual modes. This comprehensive system comprises of other smaller sub-systems that work together to alert people of any suspicious levels of heat or smoke and modern integrations include water-flow sensors. Fire detection is now a statutory enforced requirement for all buildings to reduce the risks of outbreaks.
Planning fire detection systems
In the UK, there is enforced code that fire detection systems are mandatory for all buildings. Planning often begins with setting the fire protection objectives/goals, this involves evaluating the model building codes to identify minimum mandated protection required. After goals have been established, the fire alarm designing team specifies details of the components, interfaces and procedures required to fulfill those objectives. The equipments are then designed to specific needs and standards of that building as mandated. Aspect fire solutions provide alarm systems and professional assistance in advice as well as planning and actual installation.
Components of fire detection systems
There are various parts that operate together to enable effective detection and prevention they including the following;
FACP/FACU (fire alarm control panel/unit)
This is the main component that acts as the hub, which monitors the inputs and ability of the system to function as intended. It also controls the output and relay of information to the necessary departments.
PPS (primary power supply) and Secondary power
This refers to an alternating current (120V or 240V) from commercial distribution for residential application. For non-residential applications, the fire alarm system may use dedicated branched circuits. Secondary power is basically used as backup in case of PPS failure.
This component serves as input to the FACP and can be manual or automated as preferred. These devices include heat and smoke detectors as well as pull stations. Modern developments include water-flow sensors.
Notification and safety interfaces
Notification appliances mainly include flashlights, horns or bells that inform people on the action to take mostly evacuating the room incase of fire. Safety interfaces refer to the building design which should integrate easy maneuvering (people’s escape and rescue unit entry) as well as fire and smoke spread control. It is mainly exemplified through exit doors, smoke chambers as well as circuit differentiation for controlled spread.
At Aspect fire solutions, we value the need for ultimate protection against fire and provide efficient fire detection plans for any kind of building to ensure the same. The alarm systems also include emergency pre-recorded and momentary voice messages to aid evacuation. We provide expert professionals who will enable you come up with the most effective plan for your building to ensure optimum protection and reaction to fire situations.
