Alarm systems testing

The monitoring system should be described during qualification and the alarm system tested during qualification. 

In cold weather, the trace heating on instruments that form part of trip and alarm systems should be inspected regularly. This can be part of the test routine, but more frequent testing may be necessary.

A documented procedure for periodically and systematically testing the reporting and alarm systems to confirm their functionality. 

A number of agencies (security, control room, public fire department, etc.) may be able to monitor the alarm system via direct connections. These agencies should be notified prior to a test commencing and upon completion of the test. Receipt of each alarm should be confirmed by those agencies.

Chapter 7 is the chapter dealing with Special Conditions and it addresses most of the cables with highly improved fire performance. Thus, Articles 725 (Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power-Limited Circuits), 760 (Fire Alarm Systems), and 770 (Optical Fiber Cables and Raceways) all use the same two schemes for fire performance of cables, as shown in Figures 21.4 and 21.5. The figures show that the best is NFPA 262,65 a cable fire test for flame spread and smoke, conducted in a modified Steiner tunnel (86 kW or 294,000 BTU/h), for which the requirements in the NEC are that the maximum peak optical density should not exceed 0.5, the maximum average optical density should not exceed 0.15, and the maximum allowable flame travel distance should not exceed 1.52m (5 ft). The next test, in the order of decreasing severity is UL 1666,64 known... 

First, safety critical systems must be reliable. These systems control releases in the event of accidents. It s necessary to have a critical analyzer, instrument and electrical system test program. This should consist of preventive maintenance and alarm and trip device testing for panel alarms, emergency isolation valves and other critical components. [7]...

The premises for the various laboratories should be designed to suit the operations to be carried out in them. Sufficient space should be available to avoid mix-ups, contamination and cross-contamination. There should be adequate and suitable storage space for samples, standards, instruments, equipment, solvents, reagents and records. There should be an alarm system and an adequate system to monitor the temperature of the critical stage and storage areas. If there is an automatic alarm system, it has to be tested regularly to ensure its functionality. Daily temperature records should be kept and all the alarm checks should be documented. 

Early CWA detectors were quite primitive and included primarily chemical-reactive dyes in paints. These were insensitive and therefore unreliable (Smart, 1997). Later technology used more sensitive chemical dyes in other formats such as paper tickets. Modem detectors now consist of fieldable IR spectrometers and an alarm system designed to warn of the presence of CWAs on the battlefield or in an enclosed space. Several rehable tests for the diagnosis of CWA exposure have been developed. To detect HD exposure, the level of thiodiglycol, a metabolite of HD, is quantitated in the urine using a gas chromatography/mass spectrometry (GC/MS) analytical method (Jakubowski et al., 1990 TB MED 296, 1996). Nerve agent exposure is detected in the field by the use of a fieldable Ellman assay to determine chohnesterase inhibition in the blood (Ellman et al., 1961 TB MED 296, 1996). 

Hence, the data of a single test cannot provide a basis for a conclusion about the presence or absence of toxic substances in a water body. Only a set of tests, like this ones used in present study can be applied as an alarm system to detect an acute toxicity of aquatic ecosystems. 

For guidance on fire detection and alarm system design, installation, testing and maintenance, see NFPA 72. For additional discussion on inspection, testing, and maintenance programs see Chapter 8. 

Fire Evacuation Drills - All building occupants must be familiar with what they should do during an evacuation. The most effective method of familiarizing them is to hold a fire drill at least annually. Holding a fire drill has other advantages, as well. It will provide you with an opportunity to evaluate your notification and evacuation procedures, and it will give you an opportunity to test your fire alarm system and make occupants aware of the sound. 

Fire alarm system in a combustion test facility. 

Regardless of the type of monitoring and alarm system used, whenever a new chamber is added to the system, the performance of the system should be tested with the new chamber and documented in the chamber qualification. 

Critical safety systems are usually considered to be those that are necessary for safe plant operation during processing and also those required for the safe shutdown of the plant in the event of an unanticipated malfunction. Within an incineration plant, examples of critical safety systems inclnde agent monitoring systems, testing or inspection of pressure rehef valves, ventilation flow and control systems, fire protection systems, emergency alarm and shutdown systems, process interlocks, and furnace temperature control systems.

Every laboratory facility should be equipped with at least a manually activated alarm system, although an automatic system is preferable since it wiU continue to function when the facility is unoccupied. Automatic alarms are especially useful in academic institutions since there are break periods when the population of the campus is very low. In many cases, depending upon local code requirements and the occupancy classification, an automatic fire alarm system may be required rather than optional. Every component of a system should be approved by Underwriters Laboratories, the Factory Mutual System, or other nationally recognized accrediting and testing organizations.

All systems should receive a visual inspection each quarter. Test or inspect each antomatic system on an annual basis. Include all systems in the preventive maintenance plan. Test all snpervisory signal devices except valve tamper switches on a quarterly basis. Test valve tamper switches and water flow devices semiannually. Test duct detectors, electromechanical releasing devices, heat detectors, manual fire alarm boxes, and smoke detectors on a semiannual basis. Test occupant alarm notification devices to inclnde andible and visible devices at least annually. Maintain appropriate documentation on all tire-related system testing. 

Some provisions found in NFPA 99 are stricter than those found in NFPA 72, National Alarm and Signaling Code. Buildings and structures should meet requirements found in NFPA 101 or the codes acceptable to the authority having jurisdiction. Install, test, and maintain fire alarm systems... 

There are many kinds of equipment for detecting fires and giving alarms. The devices may be quite simple, applying only to certain aspects of the process. Devices may depend on human activation or be automatic. The devices can combine several functions into sophisticated sensor, annunciator, and alarm systems. Systems require regular testing to ensure that components work properly. Systems today are likely to have computer controls. The computer may constantly perform internal checks for component failures and report which ones do not work properly. Several NFPA codes establish standards for sensor and alarm components and systems. 

During implementation, there is a need to check fire protection and extinguishing systems and equipment. Some components require regular testing, maintenance, and inspections. For example, hydrants require testing for water pressure and flow. Extinguishers, alarm systems, and sensors require inspection and testing.
