pair cable, which may have one or more parallel branches. Connect
map displays parallel to map bus. Monitoring system shall have
the capability for map bus connection of an unlimited number of
map displays and other components requiring map data. [Control
alarm reporting and display unit shall provide a capability for
annunciation of analog, audio frequency signals for the detection
subsystem using a 600-ohm time-multiplexed audio bus. Bus shall
consist of one twisted pair cable which may have one or more
parallel branches. Individual audio bus lines shall be 22 AWG or
larger wire. Connect control units parallel to the audio bus.
Processor shall have the capability for audio bus connection of at
least 127 control units and one audio annunciator.] When
operating without line repeaters or other signal regenerating or
amplifying devices, the central processor shall maintain the
performance specified herein over a control unit or map data bus
length of 2287 meters 7500 feet. When operating with
signal-regenerating line repeaters, central processor shall
maintain the performance specified herein over a control unit or
map data bus length of 22,866 meters 75,000 feet. [When operating
without line amplifiers, monitoring system shall maintain the
performance specified herein over an audio bus length of 8 km 5
miles.] Central processor shall be capable of monitoring,
annunciating, controlling, and displaying the status of at least
[508] [_____] uniquely identified zones. Central processor shall
complete each interrogation cycle of a full-capability [508]
[_____]-zone system in which the status of all zones is secure in
no more than [1.3] [_____] seconds. In smaller systems,
interrogation cycle time shall be less. Monitoring system shall
initially annunciate an alarm in a full-capability [508] [_____]
zone system within [700 milliseconds average] [1.4 seconds
maximum] [_____] after detection subsystem alarm output occurs.
Monitoring system shall complete the printout phase of alarm
annunciation within 5 seconds average, 6 seconds maximum. In
smaller systems, alarm annunciation time shall be less.

Data entry: Installation-related characteristics shall be
user-entered by simple control keyboard operations prompted by
printed displayed instructions for the operator. Entry of
installation-related data shall not require specific computer
training or knowledge of computer operation, languages, or
programming procedures, and shall neither require nor permit
processor assembly or microprocessor programming or any
modification of integral firmware. Access to data entry functions
shall be controlled by a key-operated switch or lock to prevent
data entry access by unauthorized persons. Installation-related
data entry shall include entry of the following:
(1)
Time and date
(2) For each zone: Zone number, control unit address, control
unit input number, and one of the following IDS zone descriptors:
