Fire station control

In contrast to systems that are set up to transmit local only alarms when the sensors are triggered, systems can also be set up to transmit signals to a central location, such as to a control room or guard post at the utility, or to a police or fire station. Most fire/smoke alarms are set up to signal both at the location of the event and at a fire station or central monitoring station. Many insurance companies require that facilities install certified systems that include alarm communication to a central station. For example, systems certified by the Underwriters Laboratory (UL) require that the alarm be reported to a central monitoring station. 

It may be mentioned that starting with ash and soot from crude oil-fired stations, the resulting metals are the same, but the main leaching residue is carbon. This residue is initially burned and the ash is leached again to increase the total yield of vanadium. In the same operation, the concentration of iron is reduced by precipitation of jarosite. During leaching, the redox potential is controlled by SO2 addition to keep vanadium in its IV-valent state. 

The importance of chemistry to the nuclear power industry is now well recognized. Chemical control in water circuits is an accepted part of the operating requirements of nuclear generating stations, as it is for modern fossil-fired stations. While there have been major advances in knowledge of the chemistry of aqueous systems at temperatures above lOQoC, there is still a need for further work. As we improve our understanding of thermodynamics and kinetics of solid-aqueous reactions and the effect of radiation on them, we can expect further advances in controlling radiation fields in reactor circuits and in minimizing iron deposition in GS plants. 

Fire control receives instructions from the operators and information from the radars about any current threats. Using these inputs, fire control provides instructions to the launch station, which actually controls the launch of any interceptors. Fire control can enable firing, disable firing, and so forth, and, of course, it receives feedback from the launch station about the status of any previously provided control actions and the state of the system itself. The launch station controls the actual launcher and the flight computer, which in turn controls the interceptor hardware. 

A diesel pump powered water system and portable and fixed chemical extinguishers have been provided to control any localized fire that would occur in electrical equipment or in grease, oil or solvents stored in the buildings Further, a continually manned central fire station Is located near the plant site ... 

By the late 1980s six principal commercial CEBC technologies were available (42). In 1993 the largest CEBC ia operation is expected to be the Pyropower Corporation s 165 MWe reheat coal-fired unit, under constmction siace 1991 at the Poiat Aconi Station of Nova Scotia Power Corp. (43). Combustion and SO2 control ia this unit is to be carried out ia the water-cooled riser. The unit is expected to operate at 870°C to optimize sulfur capture. The cyclone separators are refractory-lined and are supported approximately 30 m above grade. 

These couplings are totally enclosed and are suitable for any environment prone to fire hazard, corrosion, dust or any other pollutants. The controls can be provided remotely in a safer room and the pushbutton stations, which can be easily made suitable for such environments, located with the drive. 

They may be rated as more fire hazardous than a BOCB or MOCB in view of arc formation taking place ill the open, although under controlled conditions. They are not suitable for installations prone to fire hazards, unless the sub-station or the control room where they are installed is isolated from the area of hazards (Section 7.1 I). They are generally suitable for all other areas...

A fire occurs in a space station at 200 kW. The walls can be considered adiabatic and of negligible heat capacity. The initial and fuel temperatures are at 25 °C. Assume the station atmosphere has uniform properties with constant specific heats as given. Assume that the constant and equal specific heats of constant pressure and volume are 1.2 and 1.0 kJ/kg K respectively. Conduct your analysis for the control volume (CV) consisting of the station uniform atmosphere, excluding all solids and the fuel in its solid state. 

When dealing with an entire fire detection system that utilizes more than one type of detector, a Detonator Module greatly expands the flexibility and capability of the system. An individual Detonator Module can accept multiple inputs from UV and IR controllers, other Detonator Modules, manual alarm stations, heat sensors, smoke detectors or any contact closure device. In the event of a fire, any of these devices will cause the internal fire circuitry of the module to activate the detonator circuit, sound alarms, and identify the zone that detected the fire. When properly used, a Detonator Module will add only one millisecond to the total system response time. See Figure 8 for an illustration of a fire detection system with a Detonator Module. 

Alarms should be initialed by the local or main control facility for the location. Manual activation means should be provided for all emergency, fire, and toxic vapor alarm signals. Activation of fire suppression systems by automatic means should also indicate a facility alarm. Most fire and gas detection systems are also set to automatically activate alarms after confirmation and set points have been reached. Manual activation of field or plant alarm stations should activate the process or facility alarms. 

Location of Compressor Building. The main compressor building for hydrogen gas compressor stations shall be located at such clear distances from adjacent property not under control of the company as to minimize the hazard of communication of fire to the compressor building from structures on adjacent property. Sufficient open space should be provided around the building to permit the free movement of firefighting equipment. 

Control of site equipment is always important for safety and operational concerns. Many sites are remote or not staffed on a daily basis. Remediation equipment should be fitted with failsafe systems to shut down the system in the event of failure, fire, or unusual conditions (such as injection well plugging). Alarm systems should be included, which may be as simple as illuminating a warning hght, or as complex as a teleconnection to a remote computer station or telephone alert to the operator s residence. Many commercial companies offer remote monitoring equipment.
