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. The 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 this guide is read and understood.
CAUTION - System Reacceptance Test after Software Changes.
To ensure proper system operation, this product must be tested after any programming operation
or change in site-specific software. Reacceptance 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.
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 all peripherals be installed in an environment with a nominal room temperature of +15°C … +27° C.
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 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 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.
