    Fire safety equipment at a construction site in ChinaFire safety is the set of practices intended to reduce the destruction caused by fire. Fire safety measures include those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts. Fire safety measures include those that are planned during the construction of a building or implemented in structures that are already standing, and those that are taught to occupants of the building. Threats to fire safety are commonly referred to as fire hazards. A fire hazard may include a situation that increases the likelihood of a fire or may impede escape in the event a fire occurs. Fire safety is often a component of building safety. Those who inspect buildings for violations of the Fire Code and go into schools to educate children on Fire Safety topics are fire department members known as Fire Prevention Officers. The Chief Fire Prevention Officer or Chief of Fire Prevention will normally train newcomers to the Fire Prevention Division and may also conduct inspections or make presentations.

  • Alarm monitoring center

    An alarm monitoring center or central monitoring station (also known as "CMS" or wholesale alarm monitoring) is a company that provides services to monitor burglar, fire and residential alarm systems. The Central Monitoring Station may also provide watchman and supervisory services. Central monitoring stations use special telephone and mobile lines, radio channels, computers, software and trained staff to monitor their customers' security systems and call the appropriate authorities in the event an alarm signal is received. Typically, there is a monthly fee for services rendered. Because quality and experience can vary greatly among alarm companies, prospective customers are well advised to do their own research before making a final choice. Not all alarm companies monitor the systems they install and may outsource these services to another company. Some facilities are certified by independent agencies. In the USA Underwriters Laboratories (UL) is a leader in inspection and certification of central-stations. UL Standard 827 must be adhered to in order to maintain a UL issued central-station listing. UL conducts annual audits of these listed facilities to ensure compliance. "UL listed" companies typically offer higher levels of service and reliability because they are mandated to follow certain regulations. Higher levels of service also include range of services, and a separation from companies with conflicts of interest who may be owned or operated by entities that in fact compete with the central station's customers. If the UL listed central station is "automated", the computers and software must meet very special requirements processing and storing very large amounts of data and integration with many different alarm protocols. In addition, many central monitoring stations seek to become FM approved in order to demonstrate additional levels of regulation compliance and interest for customer safety. Incoming signals are processed by digital alarm receivers; these convert the incoming event packets to serial or TCP packets which are then analysed by the Central Station software. Event packets can be communicated over any transmission medium: PSTN, GSM, radio, direct line, Ethernet, GPRS, etc.

    A fire sprinkler mounted on a ceiling A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.
