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.
Adherence to the following will aid in problem-free
installation with long-term reliability:
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 interferences, 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.
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 modifications, verify that they will
not interfere with battery, transformer, and 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.
Though designed to last many years, system components
can fail at any time. This system contains 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. These instructions must be followed to avoid damage to the
control panel and associated equipment. FACP operation and
reliability depend upon proper installation by authorized personnel.
