Fire detection systems are designed to identify fires quickly, so that occupants can be safely evacuated.
Early detection can reduce property loss and interruption to operations, as well as protect emergency response personnel’s safety. Notifier smoke detectors are specifically designed for reliable performance, helping to ensure that fires are detected quickly and that people can safely evacuate.
Smoke detectors work together with fire detection systems to give you early warning when a fire breaks out. They may be battery operated or hardwired, depending on how much electricity is already present in your home or building to detect smoke and sound an alarm.
Smoke detectors come in two main varieties: ionization and photoelectric. Ionization smoke detectors use minute amounts of radioactive material between two electrically charged plates that alter the electrical balance when smoke enters a chamber.
Photoelectric detectors, on the other hand, rely on light beams to detect smoke. When smoke enters a detector’s chamber, it scatters the light beam and deflects it onto an internal sensor.
Photoelectric smoke detectors typically respond 15-50 minutes faster to fires in their early, smouldering stages than ionization alarms do, providing superior protection from both fast-flaming and slow smoldering fires. Dual-sensor smoke detectors that combine both technologies offer the best protection against both fast and slow spreading fires alike.
Carbon Monoxide Detectors
Carbon monoxide is a hazardous gas that can seep into the air from any fuel-burning appliance in your home, such as furnaces, stoves, water heaters, dryers and fireplaces. Additionally, vehicles and portable generators operated indoors also produce this gas.
Most detectors rely on either an electrochemical sensor or metal oxide semiconductor to measure carbon monoxide concentrations. When this chemical enters a sensor’s gas-permeable compartment, a change in its electrical resistance signals an alarm.
When the detector’s sensor detects a high concentration of CO, it sends an electrical charge to a microchip inside the device. This chip then sends signal to a panel which then triggers alarm activation.
Carbon monoxide detectors come in a range of styles and prices. Some require professional installation while others run off batteries or draw power from AC house current to activate the alarm.
Heat detectors sound an alert when they detect either a sudden increase in temperature, or when the ambient temperature exceeds a predetermined limit. They’re commonly used in places where smoke alarms cannot go, such as kitchens and laundry rooms.
They are also useful in detecting low energy fires. These types of fires produce only a minor amount of heat but produce significant smoke emissions.
Unlike smoke alarms, heat detectors are harder to trick and less susceptible to false alarms. They make an excellent addition to a fire detection system and can be installed in bedrooms, offices, and hallways alike.
Most heat detectors utilize either a fixed-temperature thermal sensor or a combination rate-of-rise and fixed temperature sensor. With rate of rise compensation, devices are able to react quickly to fast-building fires compared to standard, fixed temperature devices for those that develop slowly. It also reduces false alarms caused by sudden changes in ambient temperature.

Fires can happen at any time, and having fire extinguishers on hand in your facility is essential. They help put out a fire before it grows larger and blocks your escape route – especially for small business owners who may not have enough emergency personnel to respond promptly.
Fire extinguishers come in a range of types. Some use water-based solutions, while others employ dry chemicals.
Carbon dioxide extinguishers use a non-flammable gas to put out Class B and C fires. They also prevent hot embers from igniting, helping prevent the spread of fire.
AFFF: Air-aspirated foam extinguishers contain a foam concentrate which can be discharged through an air-aspirated branchpipe or spray nozzle. They’re effective against fires with high water content in their fuel.
To use an AFFF extinguisher, point the nozzle at the base of the fire and move it from side to side while still aiming at that location until all flames have been extinguished.
