Digital Alarm 50921 Rev 50921 C ECN 00 106 2000 Alarm System Limitations a fire alarm system may lower insurance it is not a substitute for fire insurance automatic fire alarm system made up of smoke heat detectors manual pull stations audible warn devices and a fire alarm control with remote notification provide early warning of a developing fire a system however does not assure protection against damage or loss of life resulting from a fire Manufacturer recommends that smoke and or heat detec be located throughout a protected premise following the of the current edition of the National Fire Association Standard 72 NFPA 72 recommendations State and local codes and recommendations contained in the Guide for Proper Use System Smoke Detectors which is made available at no to all installing dealers A study by the Federal Emer Management Agency an agency of the United States indicated that smoke detectors may not go off in many as 35 of all fires While fire alarm systems are de to provide early warning against fire they do not guar warning or protection against fire A fire alarm system not provide timely or adequate warning or simply may not for a variety of reasons detectors may not sense fire where smoke cannot the detectors such as in chimneys in or behind walls on or on the other side of closed doors Smoke detectors may not sense a fire on another level or floor of a build A second floor detector for example may not sense a or basement fire of combustion or smoke from a developing fire not reach the sensing chambers of smoke detectors be Barriers such as closed or partially closed doors walls or may inhibit particle or smoke flow Smoke particles may become cold stratify and not reach ceiling or upper walls where detectors are located Smoke particles may be blown away from detectors by air Smoke detectors may be drawn into air returns before the detector amount of smoke present may be insufficient to alarm detectors Smoke detectors are designed to alarm at levels of smoke density If such density levels are not by a developing fire at the location of detectors the will not go into alarm detectors even when working properly have sensing Detectors that have photoelectronic sensing tend to detect smoldering fires better than flaming which have little visible smoke Detectors that have ion sensing chambers tend to detect fast flaming fires than smoldering fires Because fires develop in differ ways and are often unpredictable in their growth neither of detector is necessarily best and a given type of detec may not provide adequate warning of a fire detectors cannot be expected to provide adequate of fires caused by arson children playing with especially in bedrooms smoking in bed and violent caused by escaping gas improper storage of materials etc detectors do not sense particles of combustion and only when heat on their sensors increases at a prede rate or reaches a predetermined level Rate of rise detectors may be subject to reduced sensitivity over time this reason the rate of rise feature of each detector be tested at least once per year by a qualified fire pro specialist Heat detectors are designed to protect not life Smoke detectors must be installed in the room as the control panel and in rooms used by the sys for the connection of alarm transmission wiring communi signaling and or power If detectors are not so lo a developing fire may damage the alarm system crip its ability to report a fire warning devices such as bells may not alert people these devices are located on the other side of closed or open doors or are located on another floor of a building warning device may fail to alert people with a disability or who have recently consumed drugs alcohol or medica Please note that Strobes can under certain circumstances cause seizures people with conditions such as epilepsy Studies have shown that certain people even when they a fire alarm signal do not respond or comprehend the of the signal It is the property owner responsibil to conduct fire drills and other training exercise to make aware of fire alarm signals and instruct them on the reaction to alarm signals In rare instances the sounding of a warning device can temporary or permanent hearing loss fire alarm system will not operate without any electrical If AC power fails the system will operate from standby only for a specified time and only if the batteries been properly maintained and replaced regularly used in the system may not be technically com with the control It is essential to use only equipment for service with your control panel lines needed to transmit alarm signals from a to a central monitoring station may be out of service temporarily disabled For added protection against tele line failure backup radio transmission systems are rec most common cause of fire alarm malfunction is inade maintenance To keep the entire fire alarm system in working order ongoing maintenance is required per manufacturer recommendations and UL and NFPA stan At a minimum the requirements of Chapter 7 of NFPA shall be followed Environments with large amounts of dirt or high air velocity require more frequent mainte A maintenance agreement should be arranged the local manufacturer representative Maintenance be scheduled monthly or as required by National and local fire codes and should be performed by authorized pro fire alarm installers only Adequate written records all inspections should be kept 01 10 2000 Precautions Several different sources of power can be con to the fire alarm control panel Disconnect all sources power before servicing Control unit and associated equip may be damaged by removing and or inserting cards or interconnecting cables while the unit is energized not attempt to install service or operate this unit until this is read and understood System Reacceptance Test after Software To ensure proper system operation this product be tested in accordance with NFPA 72 Chapter 7 after programming operation or change in site specific soft Reacceptance testing is required after any change ad or deletion of system components or after any modifica repair or adjustment to system hardware or wiring components circuits system operations or software func known to be affected by a change must be 100 tested addition to ensure that other operations are not inadvert affected at least 10 of initiating devices that are not affected by the change up to a maximum of 50 de must also be tested and proper system operation veri system meets NFPA requirements for operation at C 32 120 F and at a relative humidity of 85 RH non at 30 C 86 F However the useful life of the standby batteries and the electronic components be adversely affected by extreme temperature ranges humidity Therefore it is recommended that this system all peripherals be installed in an environment with a nomi room temperature of 15 27 C 60 80 F that wire sizes are adequate for all initiating and device loops Most devices cannot tolerate more a 10 I R drop from the specified device voltage to the following will aid in problem free with long term reliability all solid state electronic devices this system may erratically or can be damaged when subjected to light transients Although no system is completely from lightning transients and interferences proper will reduce susceptibility Overhead or outside wiring is not recommended due to an increased sus to nearby lightning strikes Consult with the Techni Services Department if any problems are anticipated or AC power and batteries prior to removing or in circuit boards Failure to do so can damage circuits all electronic assemblies prior to any drilling filing or punching of the enclosure When possible make cable entries from the sides or rear Before making modifi verify that they will not interfere with battery trans and printed circuit board location not tighten screw terminals more than 9 in lbs may damage threads resulting in reduced contact pressure and difficulty with screw terminal designed to l
