Lighting fire control

Internal combustion and electricity wrought a number of changes in naval architecture. Electric power was introduced on warships in the 1880s, allowing for the construction of larger ships, with better light and ventilation, deeper decks, improved artillery fire control, and improved efficiency in han-...

Generally, electrical control systems are designed Fail-Safe. If power is temporarily lost, unnecessary shutdown of the process may occur. Thus, most safety systems such as fire and gas detectors, Nav-Aids, communications, and emergency lighting require standby D.C. power. 

It has long been known that certain insects (e.g. the beetles known as fire flies) and two or three genera of bacteria possess the ability to emit light this property has been utilized in quality control and research. 

The excellent detection ability for flames makes UV sensing a good method for remote fire alarm-monitoring. UV radiation after the outbreak of a fire reaches a sensor much faster than heat or smoke. Also, the distance between sensor and fire is less critical. Requirements for the sensor are high sensitivity and excellent selectivity. Radiation intensities at the sensor position may be even lower and the ambient light conditions less restricted than for combustion controlling. When used outside, solar-blindness is a must. These stringent requirements make UV fire alarm monitors expensive, and they are used in industrial environments such as production floors or warehouses rather than in private homes. 

Alarms should be displayed on a conventional dedicated window annuciator panel or if control room based on a dedicated CRT display for fire and gas detection systems. Each detector location should be highlighted with indications for trouble, alarm low, and alarm high. Where annuciator panel window alarms the alarm indication lights should be provided with specific labels indicating the exact alarm locations.
