Notifier Nfs 3030 Programming Manual
—typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control panel with remote notification capability—can provide early warning of a develop- ing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire. The Manufacturer recommends that smoke and/or heat detec- tors be located throughout a protected premise following the recommendations of the current edition of the National Fire Protection Association Standard 72-1999 (NFPA 72-1999), manufacturer's recommendations, State and local codes, and the recommendations contained in the Guide for Proper Use of System Smoke Detectors, which is made available at no charge to all installing deale rs. A study by the Federal Emer- gency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off in as many as 35% of all fires. While fire alarm systems are designed to provide early warning against fire, they do not guarantee warning or protection against fire.
A fire alarm sys- tem may not provide timely or adequate warning, or simply may not function, for a variety of reasons. From a developing fire may not reach the sensing chambers of smoke detectors because:.
Barri ers su ch as closed or p artial ly clo sed d oors, walls, or chimneys may inhibit particle or smoke flow. Smoke partic les ma y beco me “c old,” strati fy, and not re ach the ceiling or upper walls where detectors are located. Smoke parti cles m ay be blown away fr om de tectors by ai r outlets. Smoke partic les ma y be drawn into a ir re turns befor e reaching the detector.

The amount of “smoke” present may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm at various levels of smoke density.
If such density levels are not created by a developing fire at the location of detectors, the detectors will not go into alarm. Smoke detectors, even when working properly, have sensing limitations. Detectors that h ave photoelectronic sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ion- izing-type sensing chambers tend to detect fast-flaming fires better than smoldering fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is necessarily best and a given type of detector may not provide adequate warning of a fire. Smoke detectors cannot be expected to provide adequate warning of fires caused by arson, children playing with matches (especially in bedrooms), smoking in bed, and violent explosions (caused by escaping gas, improper storage of flammable materials, etc.). Such as bells may not alert people if these devices are located on the other side of closed or partly open doors or are located on another floor of a building.
Any warning device may fail to alert people with a disability or those who have recently consumed drugs, alcohol or medica- tion. Please note that:. Str obes can, u nder certa in ci rcumsta nces, cause seizur es in people with conditions such as epilepsy. Stu dies have s hown that c ertai n peo ple, even when they hear a fire alarm signal, do not respond or comprehend the meaning of the sign al. It is the property owner's responsi- bility to conduct fire drills and other training exercise to make people aware of fire alarm signals and instruct them on the proper reaction to alarm signals.
In rar e ins tance s, the sound ing o f a w arning device can cause temporary or permanent hearing loss. Of fire alarm malfunction is inade- quate maintenance. T o keep the entire fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer's recommendations, and UL and NFPA stan- dards. At a minimum, the requirements of Chapter 7 of NFPA 72-1999 shall be followed.
Environments with large amounts of dust, dirt or high air velocity require more frequent mainte- nance. A maintenance agreement should be arranged through the local manufacturer's representative. Maintenance should be scheduled monthly or as required by National and/ or local fire codes and should be performed by authorized pro- fessional fire alarm installers only. Adequate written records of all inspections should be kept. T o ensure proper system operation, this product must be tested in accordance with NFPA 72-1999 Chapter 7 after any programming operation or change in site-specific software. Reacceptance testing is requ ired after any change, addition or deletion of system components, or after any modifi- cation, repair or adjustment to system hardware or wiring.
All components, circuits, system operations, or software func- tions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvert- ently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices, must also be tested and proper system operation ver- ified. Meets NFPA requirements for operation at 0°C to 49°C (32°F to 120°F) and at a relative humidity (noncon- densing) of 85% at 30°C (86°F) per NFPA, and 93% ± 2% at 32°C ± 2°C (89.6°F ± 1.1°F) per ULC. However, the useful life of the system's standby batteries and the electronic compo- nents may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and all peripherals be installed in an environment with a nominal room temperature of 15-27° C/60-80° F. This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instruction manual, may cause interference to radi o communications. It has been tested and found to comply with the limits for class A computing device pursuant to Subpart B of Part 15 of FCC Rules, which is designed to provide reasonable protection against such interference when operated in a commercial environment.
Operation of this e quipment in a residential area is likely to cause interference, in which case the user will be required to correct the interference at his own expense.
