8.2.2.1  Local.  Local termination refers to the scheme of alarm reporting
which provides very limited separation of alarm reports.  The reporting
device is usually a bell or siren mounted on the building exterior to
provide indication of alarm related to the whole facility.  The advantage of
this type of report is that attention is directed to the place of alarm and
the intruder knows that a detection has been sensed.  The disadvantage of
this system is in the simplicity of the physical attack needed to disable
the reporting device and the reliability of depending upon others for report
communications.  This is a low threat, minimum security option.
8.2.2.2  Central Station.  The central station termination scheme is a
reporting option which uses a shared monitoring service.  The typical system
configuration consists of a premise alarm reporting from one to several
coded alarm conditions to a monitoring receiver normally via a dial
telephone network.  The monitoring personnel (who are typically monitoring
other subscribers concurrently) then inform authorities or responding forces
of the location and type of alarm event.  This information is limited to the
detail of separation in alarm zones at the facility.  Historical records
kept by the central station may be of limited value in reconstruction of
events reported by the premise alarm system.  Various levels of Central
Station security coverage are available and should be keyed to the threat
requirements.
