•
Verify that wire sizes are adequate for all initiating and indicating
device loops.
N25
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 interferences, proper grounding will reduce
susceptibility. Overhead or outside aerial wiring is not recommended,
due to an increased susceptibility to near lightning strikes. Consult
technical support 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 lb
.
in. Overtightening
may damage threads, resulting in reduced terminal contact pressure
and difficulty with screw terminal removal.
•
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.
