1.3 Limitations of Fire Alarm Systems
An automatic fire alarm system can provide early
warning and notification of the development of a
fire. It can’t, however, assure protection against
loss of property or loss of life.
It is recommended that smoke and/or heat
detectors and notification appliances be installed
throughout the building in accordance with the
requirements detailed in NFPA 72, local/state
codes, and with the instructions supplied with the
equipment.
The type(s) of detector employed and their physical
location must be selected carefully to ensure that
they detect the types of fire likely to occur in the
protected area. Even so, a number of factors may
prevent the necessary levels of combustion
products from reaching the sensing chambers and
thus the system may not indicate an alarm
condition.
Heat detectors protect property, not life.
Smoke detectors shall be installed in the same
room(s) as the fire alarm control panel, any
equipment used for transmission of the alarm
condition, and in locations where power supplies
are mounted. Otherwise, a developing fire may
damage the system and its ability to report the fire
alarm condition, refer to NFPA 72.
The system will not operate without power.
Standby batteries shall be properly maintained and
replaced regularly.
Regular maintenance will ensure that the system is
operating at its optimum performance. Arrange a
maintenance agreement with the manufacturer’s
local representative to ensure that the system is
maintained by a professional fire alarm installer in
accordance with National and any local/state
codes. Maintain a written record of all inspections
and maintenance performed.
1.4 General Installation Notes
WARNING: Disconnect all sources of power (AC
and battery) before installing components or
servicing the system.
DO NOT install/remove circuit cards while the fire
alarm control panel is supplied with power (either
AC or battery).
ENVIRONMENT: INSTALL the equipment in a
clean, dry environment.
The equipment meets the requirements for
operation at 32°F - 120°F (0°C - 49°C) and relative
humidity of 85% RH. However, standby battery life
is drastically reduced at higher temperatures. The
recommended room temperature for installation is
60°F - 86°F (15°C - 27°C).
WIRING: CHECK that the installation wire sizes
are adequate to deliver the required load current
and maintain compatibility with the specific device
operating voltages.
USE an anti-static wrist strap
whenever handling circuit cards.
STORE circuit cards in static
suppressive packaging.
CAUTION: Acceptance / Re-acceptance Tests
Following installation or after any system change
(including changes to operating software or
configuration settings) the system shall be tested in
accordance with the requirements in NFPA 72 and
any local/state codes.
All affected functions or devices shall be 100%
tested. In addition, at least 10% of initiating devices
not directly affected by the change shall also be
tested.
Follow the recommendations of NFPA 72.
A secure dedicated ground connection is
required. Although no system is immune
to the effects of lightning strikes, a
secure ground connection will reduce
susceptibility. The use of overhead or
outside aerial wiring is not
recommended.
Installation of a fire alarm system may
lower insurance rates, BUT it is not a
substitute for fire insurance!
