Fire Alarm Systems

fire alarm

A fire alarm system has several devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated from smoke detectors, and heat detectors or may also be activated via manual fire alarm devices such as manual call points or pull stations.

In some cases, magnetic smoke door retainers are used: wall mounted solenoids or electromagnets controlled by a fire alarm system or detection component that magnetically secures spring-loaded self-closing smoke tight doors in the open position — designed to de-magnetize to allow automatic closure of the door on command from the fire control or upon failure of the power source, interconnection or controlling element.

Duct mounted smoke detection: smoke detection mounted in such a manner as to sample the airflow through ductwork and other plenums fabricated explicitly for the transport of environmental air into conditioned spaces. Interconnection to the fan motor control circuits is intended to stop air movement, close dampers and generally prevent the recirculation of toxic smoke and fumes produced by fire into occupiable spaces.

Emergency elevator service: activation of automatic initiating devices associated with elevator operation are used to initiate emergency elevator functions, such as recall of associated elevator cab. The recall will cause the elevator cabs to return to the ground level for use by fire service response teams and to ensure that cabs do not return to the floor of fire incidence, also, to prevent people from becoming trapped in the elevators. Phases of operation include primary recall, alternate/secondary recall (typically a floor adjacent to the ground level – used when the initiation occurred on the primary level),

The system should be installed throughout the building – the objective being to call the fire brigade as early as possible to ensure that any damage caused by the fire is minimized. Little low-risk areas can be accepted such as toilets and cupboards less than 1m.

In your IT infrastructure fire alarms and suppression is a necessity.  Whether you have or want, Fire sprinkler systems (wet, dry, pre-action and deluge), Gaseous agents, Wet and dry chemical agents, or just Water Technology Infrastructure can help in design, and planning for existing and new project expansion to ensure seamless protection.
