through each portal at peak traffic periods with
system response and processing times for each
passage request taken into account.
**************************************************************************
At the specified error rates, the system throughput rate through a single
portal shall be as shown.
1.2.15
Passage
**************************************************************************
NOTE: The designer will show on the drawings
whether entry control is used for ingress or egress
at each portal.
**************************************************************************
Passage is defined as ingress and/or egress past an entry control device,
or through a portal. Entry control procedures and equipment shall be
implemented for passage through each portal as shown.
1.2.16
Detection Resolution
The system shall have detection resolution sufficient to locate intrusions
at each device and zone; and tampering at individual devices.
1.2.17
Electrical Requirements
**************************************************************************
NOTE: The designer will select the correct line
frequency and voltage and show on the drawings the
characteristics of each voltage source.
**************************************************************************
Electrically powered ESS equipment shall operate on [120] [240] volt [60]
[50] Hz ac sources as shown. Equipment shall be able to tolerate
variations in the voltage source of plus or minus 10 percent, and
variations in the line frequency of plus or minus 2 percent with no
degradation of performance.
1.2.18
System Reaction
**************************************************************************
NOTE: The designer must determine the required
system end-to-end response. Short response times
such as 1 second, are only required for systems
where alarm actuated CCTV assessment will be
applied. In other situations, response times as
high as 3 or 4 seconds are acceptable. Large
systems with many entry control devices may be
unable to achieve short response times.
**************************************************************************
1.2.18.1
System Response
The field device network shall provide a system end-to-end response time of
[1 second] [_____] or less for every device connected to the system.
Alarms shall be annunciated at the central station within [_____] of the
alarm occurring at a local processor or device controlled by a local
processor, and within 100 milliseconds if the alarm occurs at the central
