Notification

Notification systems take many forms – audible, visual or a combination. Through our network of industry suppliers and our expertise in comprehensive fire protection, Hiller can recommend the appropriate solution to ensure your safety. Reliable detection and notification systems are a key barrier to devastating loss. We also provide inspection, maintenance and repair services on commercial notification and detection systems to ensure the protection of lives and property.

Flame detectors are needed for facilities where risk of loss to personnel and property is high. The systems respond to radiant energy, both visible to the human eye and undetectable to the human eye. Flame detector devices are sensitive to glowing embers, coals and flames that are detectable by intensity and spectral quality. There are three types of flame detection systems: infrared, ultraviolet and infrared/ultraviolet.

Common Applications:

  • Oil and gas pipelines
  • Turbine enclosures
  • Off-shore platforms
  • Automotive manufacturing facilities
  • Aircraft hangers
  • Munitions plants
  • Nuclear facilities

Threats Detected:

  • Hot spots before they ignite
  • Smoke
  • Fire

Early warning fire detection systems use thermal imaging to detect hot spots before they even ignite. This technology can prevent fires from spreading and destroying life and property, especially in hazardous areas such as scrapyards, shredder facilities and flammable materials storage areas. Combining thermal imaging cameras with remote control fire suppression systems can greatly reduce the outbreak of fire.

Common Applications:

  • Telecommunication centers
  • Data centers
  • Clean rooms
  • Server rooms
  • Theaters
  • Warehouses
  • Indoor stadiums
  • Convention Centers

Threats Detected:

  • Hot spots before they ignite
  • Smoke
  • Fire

Air sampling detectors can detect a fire at its earliest stage by actively pulling air into a detection chamber through a piping network that runs from the device to the protection area. Particles that are formed in the early stages of combustion – even before smoke or fire is visible – are detectable through this proactive system. There are three types of air sampling detection methods: laser systems – filtered, laser systems – particle counting and cloud chamber systems.

Common Applications:

  • Telecommunication centers
  • Data centers
  • Clean rooms
  • Server rooms
  • Theaters
  • Warehouses
  • Indoor stadiums
  • Convention Centers

Threats Detected:

  • Smoke
  • Fire

Smoke detection systems use devices that react to particles produced by fire. There are two principles of smoke particle analysis used in spot smoke detectors: ionization and photoelectric. Both methods work effectively to detect fire in the early stages of development. Devices are often installed in ventilation ducts. It is important to have a fire protection specialist determine the best system and location for smoke alarm systems based on your building fire-load conditions.

Common Applications:

  • Office buildings
  • Homes
  • Schools
  • Museums
  • Data Centers

Threats Detected:

  • Smoke
  • Fire

Video surveillance cameras and computer vision methods are now available in fire detection systems. With intelligent video processing techniques and special purpose infrared surveillance cameras, fire can be detected and analyzed. Detection time is often reduced because cameras do no have transport delays present in traditional detection systems. Video also provides critical information such as size of fire, rate of growth and direction of spread.

Common Applications:

  • Oil rigs
  • Oil fields
  • Mining operations
  • Forestry service
  • Industrial facilities
  • Warehouses
  • Testing facilities

Threats Detected:

  • Smokey fires
  • Flaming fires

A traditional fire alarm notification system is designed to alert occupants as well as a designated monitoring company. Once smoke and heat detectors recognize the potential existence of fire, the control panel triggers flashing strobe lights and horn alarms to inform occupants of the need to evacuate. The operator of the monitoring center then dispatches emergency responders.

Common Applications:

  • Places of assembly, typically of 50 or more people
  • High rise buildings where zoned evacuation may be needed

Threats Detected:

  • Fire
  • Severe weather
  • Gas leaks
  • Chemical spills
  • Intruders

Fire alarm voice evacuation notifications use speakers and amplifiers to provide more information to occupants of facilities during an emergency. A fire alarm tone is followed by voice instructions rather than a horn or bell. It also allows for emergency responders to broadcast live messages through a local paging microphone.

Common Applications:

  • Places of assembly, typically of 50 or more people
  • High rise buildings where zoned evacuation may be needed

Threats Detected:

  • Fire
  • Severe weather
  • Gas leaks
  • Chemical pills
  • Intruders

Mass Notification is defined by the U.S. Department of Defense as “the capability to provide real-time information to all building occupants or personnel in the immediate vicinity of a building during emergency situations. To reduce the risk of mass casualties, there must be a timely means to notify building occupants of threats and what should be done in response to those threats.” Through technology, Hiller can design a comprehensive solution not only to notify people of danger, but to instruct them of action to take to avoid it. Mass Notification Systems are a combination of systems for input, detection and output that allows a facility to keep its occupants informed every step of the way. Notifications include traditional speakers and strobes and also include email blasts, text messages, voice messages, computer pop-ups and electronic bulletin boards.

Common Applications:

  • Universities
  • Schools
  • Industrial facilities
  • Vessels
  • Municipalities

Threats Detected:

  • Fire
  • Chemical spills
  • Natural disasters
  • Terrorist activities
