a computational procedure
turning the detector off and then powering it up again
digital signal processing
the complete system, from detection through suppression, is tested
communications protocol used for transmitting data from a detector to
a Windows-based computer
retrievable pre-fire data storage protocol, used for analysis and pos-
tulation of the cause of a fire
signal analysis based on frequency instead of time
infrared; the wavelengths of light from approximately 700 nanometers
to 1 millimeter
a serial communication protocol
unit of measure equal to one one-billionth (10
nated nm
normally closed (electrical short circuit, by default)
normally open (electrical open circuit, by default)
data stored on a chip that is not lost when the detector's power is
cycled.
unit of measure equal to one one-millionth (10
nanometers; designated μm
random access memory or read and write memory
read-only memory
near-instantaneous analysis and response by a device, usually mea-
sured in milliseconds or microseconds
a test of all of a system's components, performed automatically on
start-up and periodically during normal operation
signal analysis based on time
testing a detector with a test lamp
ultraviolet; the wavelengths of light from approximately 10 nanome-
ters to 400 nanometers.
a broad range of wavelengths within the infrared spectrum
