Installation ProcedureAdherence to the following will aid in problem-free installation with long-term reliability:Installation Precautions - Adherence to the following will aid in problem-free installationwith long-term reliability: WARNING - Several different sources of power can be connectedto the fire alarm control panel. Disconnect all sources of power before servicing. Control unitand associated equipment may be damaged by removing and/or inserting cards, modules, orinterconnecting cables while the unit is energized. Do not attempt to install, service, or operatethis unit until manuals are read and understood. CAUTION - System Re-acceptance Test afterSoftware Changes: To ensure proper system operation, this product must be tested inaccordance with NFPA 72 after any programming operation or change in site-specificsoftware. Re-acceptance testing is required after any change, addition or deletion of systemcomponents, or after any modification, repair or adjustment to system hardware or wiring. Allcomponents, circuits, system operations, or software functions known to be affected by achange must be 100% tested. In addition, to ensure that other operations are not inadvertentlyaffected, at least 10% of initiating devices that are not directly affected by the change, up to amaximum of 50 devices, must also be tested and proper system operation verified. Thissystem meets NFPA requirements for operation within the range of 0°C-49°C (32°F-120°F) orhumidity within the range of 10%-93% at 30°C (86°F) noncondensing. However, the usefullife of the system's standby batteries and the electronic components may be adversely affectedby extreme temperature ranges and humidity. Therefore, it is recommended that this systemand its peripherals be installed in an environment with a normal room temperature of 15-27ºC/60-80º F. Verify that wire sizes are adequate for all initiating and indicating device loops.Most devices cannot tolerate more than a 10% I.R. drop from the specified device voltage.Like all solid state electronic devices, this system may operate erratically or can be damagedwhen subjected to lightning induced transients. Although no system is completely immunefrom lightning transients and interference, proper grounding will reduce susceptibility.Overhead or outside aerial wiring is not recommended, due to an increased susceptibility tonearby lightning strikes. Consult with the Technical Services Department if any problems areanticipated or encountered. Disconnect AC power and batteries prior to removing orinserting circuit boards. Failure to do so can damage circuits. Remove all electronicassemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible,make all cable entries from the sides or rear. Before making modifications, verify that theywill not interfere with battery, transformer, or printed circuit board location. Do not tightenscrew terminals more than 9 in-lbs. Over-tightening may damage threads, resulting inreduced terminal contact pressure and difficulty with screw terminal removal. Silent Knightfire alarm control panels contain static-sensitive components. Always ground yourself with aproper wrist strap before handling any circuits so that static charges are removed from thebody. Use static suppressive packaging to protect electronic assemblies removed from theunit.Follow the instructions in the installation, operating, and programming manuals. Theseinstructions must be followed to avoid damage to the control panel and associated equipment.FACP operation and reliability depend upon proper installation.
