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 pro-
gramming 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 compo-
nents, 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 at 0-49º
C/32-120º F and at a relative humidity. However, the useful
life of the system's standby batteries and the electronic com-
ponents 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 indi-
cating 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 light-
ning 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 sus-
ceptibility to nearby lightning strikes. Consult with the Techni-
cal Services Department if any problems are anticipated or
encountered.
Disconnect AC power and batteries
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 modifi-
cations, verify that they will not interfere with battery, trans-
former, 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.
This system contains static-sensitive components.
A
lways ground yourself with a proper wrist strap before han-
dling 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. These instructions must be followed to
avoid damage to the control panel and associated equipment.
FACP operation and reliability depend upon proper installa-
tion.
