Flame detectors report the presence of visible fires within a protected area. Smoke detectors respond to the combustion products emitted by burning materials. Heat Detectors respond to excessively high temperatures in the protected area, which are presumed to be the result of a fire in the area. Fire Standards require the use of Manual Alarm Stations in all areas occupied by people.

Use a combustible gas sensor to insure that the percentage of gas in the air can never get high enough for the mixture to burn. Toxic gas sensors insure that no personnel are injured or killed by toxic leak accidents. Use an oxygen sensor to alert personnel of extreme fire danger.

The Alarm Control Panel receives electrical signals from the various fire detectors and gas sensors located through out the protected area. The control panel displays the status of each connected detector or sensor, reporting alarm conditions and measured gas concentrations. The control panel also reports any detector/sensor device that is not working properly, so that maintenance personnel may be dispatched to repair the device.

For hazardous locations these include bells, horns, hooters, sirens, and strobe lights for installation in areas where gases or flammable vapors can accumulate. These devices are rated explosion proof or intrinsically save. For non-hazardous locations these include bells, horns, hooters, sirens, and strobe lights for installation in general purpose areas where only common combustible materials are present.

Upon detection of a fire and alerting of personnel, the fire must be extinguished. Today’s clean agents are formulated to not only produce the desired extinguishing characteristics, but also to minimize the long term effects that any of these agents have on the environment when released. Regardless of any automatic equipment installed, standards also require hand portable extinguishers for use by occupants of protected areas.

Solar panels have traditionally been used to power a single detector at a remote location where no power service is available. Gas detectors have been used for years along pipelines in this application. Today’s solar panels are more efficient and less costly, making them a viable option anywhere that sun is available and can now become a component of an environmentally friendly detector installation.
