3.1 Installation Precaution

Installation Precautions

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

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 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.

This system meets NFPA requirements for indoor dry

operation 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 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 0-

50° C/32-120° F.
