protection against telephone line failure, backup radio transmission systems are
recommended.
The most common cause of fire alarm malfunction is insufficient maintenance. To
keep the entire fire alarm system in excellent working order, ongoing maintenance is
required as the manufacturer’s recommendations, and UL and NFPA 72 shall be
followed. Environments with large amounts of dust, dirt or high air velocity require
more frequent maintenance. A maintenance agreement should be arranged through the
local manufacturer’s representative. Maintenance should be scheduled monthly or as
required by National and/or local fire codes and should be performed by authorized
professional fire alarm installers only. Adequate written records of all inspection
should be kept.
1.4 Installation Precautions
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.
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 fully.
CAUTION
–
System Reacceptance Testing Requirements. 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. 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 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 up to 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 15-27°C/60-80° F.
Verify that wire sizes are adequate for all initiating and indicating device loops. Refer
to the manual specifications section for maximum allowable I.R. drop from the
specified device voltage.
Like all solid state electronic devices, this system may operate erratically or can be
