Installation Precautions

WARNING - Several different sources of power can be con- nected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equip- ment 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 manual is read and understood.

CAUTION - System Reacceptance 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 components, circuits, system operations, or software func- tions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvert- ently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 de- vices, must also be tested and proper system operation veri- fied.

This system meets NFPA requirements for indoor dry opera- tion at 0-49° C/32-120° F and at a relative humidity of 93 ±2% RH (non-condensing) at 32 ±2° C/90 ±3° F. However, the useful life of the system's standby batteries and the elec- tronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recom- mended that this system and all peripherals be installed in an environment with a nominal room temperature of 15-27° C/60-80° 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.

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 com- pletely immune from lightning transients and interferences, proper grounding will reduce susceptibility. Overhead or out- side aerial wiring is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the Technical Services Department if any problems are antici- pated or encountered.

Disconnect AC power and batteries prior to removing or in- serting 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, 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 re- moved 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.
