Installation Procedure
Installation 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 alarm control panel. Disconnect all sources of power
before servicing. Control unit and associated equipment may be damaged by
removing and/or inserting cards, modules, or interconnecting cables while the unit is
energized. Do not attempt to install, service, or operate this unit until manuals are
read and understood. CAUTION - System Re-acceptance Test after Software
Changes: To ensure proper system operation, this product must be tested in
accordance with NFPA 72 after any programming operation or change in site-specific
software. Re-acceptance testing is required after any change, addition or deletion of
system components, or after any modification, repair or adjustment to system
hardware or wiring. All components, circuits, system operations, or software functions
known to be affected by a change must be 100% tested. In addition, to ensure that
other operations are not inadvertently 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 verified. This system meets NFPA requirements
for operation within the range of 0°C-49°C (32°F-120°F) or humidity within the range
of 10%-93% at 30°C (86°F) noncondensing. However, the useful life of the system's
standby batteries and the electronic components may be adversely affected by
extreme temperature ranges and humidity. Therefore, it is recommended that this
system and its peripherals be installed in an environment with a normal room
temperature of 15-27º C/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 damaged when subjected to lightning
induced transients. Although no system is completely immune from lightning
transients and interference, proper grounding will reduce susceptibility. Overhead or
outside aerial wiring is not recommended, due to an increased susceptibility to
nearby lightning strikes. Consult with the Technical Services Department if any
problems are anticipated or encountered. Remove DC power prior to removing or
inserting circuit boards. Failure to do so can damage circuits. Remove all electronic
assemblies 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 they will not interfere with battery, transformer, or printed circuit board
location. Do not tighten screw terminals more than 9 in-lbs. Over-tightening may
damage threads, resulting in reduced terminal contact pressure and difficulty with
screw terminal removal. Fire alarm control panels contain static-sensitive
components. Always ground yourself with a proper wrist strap before handling any
circuits so that static charges are removed from the body. Use static suppressive
packaging to protect electronic assemblies removed from the unit.
Follow the instructions in the installation, operating, and programming manuals.
