It has been tested and found to complywith the limits for class A computing device pursuant to Subpart B of Part 15 of FCCR ules, which is designed to provide reasonable protection against such interferencewhen operated in a commercial environment.

2 Operation of this equipment in aresidential area is likely to cause interference, in which case the user will be requiredto correct the interference at his own Precautions - Adherence to the following will aid in problem-free installation with long-term reliability:WARNING - Several different sources of power can be connected to the fire alarmcontrol panel. Disconnect all sources of power before servicing. Control unit andassociated equipment may be damaged by removing and/or inserting cards,modules, or interconnecting cables while the unit is energized. Do not attempt toinstall, service, or operate this unit until this manual is read and - System Reacceptance Test after Software Changes: To ensureproper system operation, this product must be tested in accordance with NFPA 72-1993 Chapter 7 after any programming operation or change in site-specific testing is required after any change, addition or deletion of systemcomponents, or after any modification, repair or adjustment to system hardware components, circuits, system operations, or software functions known to beaffected by a change must be 100% tested.

3 In addition, to ensure that otheroperations are not inadvertently affected, at least 10% of initiating devices that arenot directly affected by the change, up to a maximum of 50 devices, must also betested and proper system operation system meets NFPA requirements for operation at 0-49O C/32-120O Fand at a relative humidity of 85% RH (non-condensing) at 30O C/86O , the useful life of the system's standby batteries and the electroniccomponents may be adversely affected by extreme temperature ranges andhumidity. Therefore, it is recommended that this system and its peripherals beinstalled in an environment with a nominal room temperature of 15-27O that wire sizes are adequate for all initiating and indicating device devices cannot tolerate more than a 10% drop from the specified all solid state electronic devices, this system may operate erratically or canbe damaged when subjected to lightning induced transients.

4 Although no system iscompletely immune from lightning transients and interferences, proper grounding willreduce susceptibility. Overhead or outside aerial wiring is not recommended, due toan increased susceptibility to nearby lightning strikes. Consult with the TechnicalServices Department if any problems are anticipated or AC power and batteries prior to removing or inserting circuit to do so can damage all electronic assemblies prior to any drilling, filing, reaming, or punchingof the enclosure. When possible, make all cable entries from the sides or making modifications, verify that they will not interfere with battery,transformer, and printed circuit board not tighten screw terminals more than 9 in-lbs.

5 Over tightening may damagethreads, resulting in reduced terminal contact pressure and difficulty with screwterminal system contains static-sensitive components. Always ground yourself with aproper wrist strap before handling any circuits so that static charges are removedfrom the body. Use static suppressive packaging to protect electronic assembliesremoved from the the instructions in the installation, operating, and programming instructions must be followed to avoid damage to the control panel andassociated equipment. FACP operation and reliability depend upon Alarm System LimitationsWhile installing a fire alarm system may make lower insurancerates possible, it is not a substitute for fire insurance!

6 An automatic fire alarm system - typically made up of smoke detectors, heatdetectors, manual pull stations, audible warning devices, and a fire alarm controlwith remote notification capability can provide early warning of a developing a system, however, does not assure protection against property damage orloss of life resulting from a fire alarm system may fail for a variety of reasons:Smoke detectors may not sense fire where smoke cannot reach the detectors suchas in chimneys, in walls, or roofs, or on the other side of closed doors. Smokedetectors also may not sense a fire on another level or floor of a building.

7 A secondfloor detector, for example, may not sense a first floor or basement fire. Further-more, all types of smoke detectors - both ionization and photoelectric types, havesensing limitations. No type of smoke detector can sense every kind of fire causedby carelessness and safety hazards like smoking in bed, violent explosions,escaping gas, improper storage of flammable materials, overloaded electricalcircuits, children playing with matches, or ! Smoke detectors must be installed in the same room as thecontrol panel and in rooms used by the system for the connection of alarmtransmission wiring, communications, signaling, and/or power.

8 If detectors arenot so located, a developing fire may damage the alarm system, crippling itsability to report a warning devices such as bells may not alert people if these devices arelocated on the other side of closed or partly open doors or are located on anotherfloor of a fire alarm system will not operate without any electrical power. If AC power fails,the system will operate from standby batteries only for a specified heat detectors may be subject to reduced sensitivity over time. Forthis reason, the rate-of-rise feature of each detector should be tested at least onceper year by a qualified fire protection used in the system may not be technically compatible with the is essential to use only equipment listed for service with your control lines needed to transmit alarm signals from a premise to a centralmonitoring station may be out of service or temporarily most common cause of fire alarm malfunctions, however, is inadequatemaintenance.

9 All devices and system wiring should be tested and maintained byprofessional fire alarm installers following written procedures supplied with eachdevice. System inspection and testing should be scheduled monthly or as requiredby National and/or local fire codes. Adequate written records of all inspections shouldbe WarningCanadian RequirementsThis digital apparatus does not exceed the Class A limits for radiation noiseemissions from digital apparatus set out in the Radio Interference Regulations of theCanadian Department of present appareil numerique n'emet pas de bruits radioelectriques depassant leslimites applicables aux appareils numeriques de la classe A prescrites dans leReglement sur le brouillage radioelectrique edicte par le ministere des Communica-tions du Publishing Document 12/31/96 Technical Manuals Online!
