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 0-25° C/32-77° F and at a relative humidity
of 93 ±2% RH (non-condensing) at 25 ±2° C/77 ±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 15-
25° C/60-77° F.
