SmartSeries® Emergency Notification and Public Address System
A Petrochemical Corporation constructed a new oil refinery in MiaLiao, Taiwan and needed a
communication and emergency notification system. GAI-Tronics wrote a specification to meet
the customer’s requirements, which included:
· Emergency notification to all required areas of the facility.
· Self-diagnostic circuitry in all critical system components and associated system cabling.
· Intelligent primary and backup alarm tone and speech generators included in the central
Control Cabinet to allow emergency tones/messages to be broadcast to designated zone(s).
· Selective paging of zones in each sub-system via the Control Panels.
· Entertainment system included in the Control Cabinet.
· Use of fiber optic cabling.
· Interface to central amplifier zones for areas of the facility not requiring communication
· Minimized cabling between the control cabinet and each control panel.
· Ability to link the entire facility via a Display Server. Master cabinet will provide status
monitoring for exchange of relevant data and audio throughout system.
GAI-Tronics Corporation provided a SmartSeries® Emergency Notification and Central Amplifier
System consisting of 8 subsystems controlled by 4 SmartSeries® Control Cabinets. Each
subsystem comprises a distributed amplifier communication zones and central amplifier public
address zones. Each zone is equipped with speakers, handset stations, control panels and related
equipment as needed. Finally, notification of system integrity and activation of alarm tones can
occur at Local and Master Control Panels.

Basic System Overview
The entire system consists of four SmartSeries® Control Cabinets, each containing two
subsystems. Each subsystem currently operates standalone, but will ultimately all be linked when
the SmartStatus Display Server is installed later this year. The entire system operates on fiber
optic cable to minimize installation costs and cable requirements.
Each subsystem includes a combination of Master and Local Control Panels, central amplifier
systems, alarm initiation and broadcast capabilities, and varying configurations of field equipment,
including SmartSeries® stations and speakers. Each system component is discussed below.
Master and Local Control Panels
The Master and Local Control Panels all have the capability to initiate alarms and generate pages.
Pages generated within each subsystem may be directed to one, several, or all individual zones
within that subsystem. The Master Control Panels, equipped with VFD displays, will be able to
generate sitewide pages once the SmartStatus Display Server is installed and commissioned. The
Local Control Panels, not equipped with VFDs, can only generate pages within the subsystem.
Central Amplifier Systems
Each of the individual subsystem SmartSeries® Control Cabinets is equipped with between 6 and
twenty-six interface cards for the central amplifier system. The central amplifier zones are used
to provide speaker coverage in areas of the facility that do not require SmartSeries® handset or
speaker amplifier stations.
In addition, each system is equipped with an entertainment system, which broadcasts background
music over the central amplifier system to select areas of the facility. The broadcast of the
background music will, in accordance with emergency notification system requirements, be
automatically overridden by any system pages or alarms.
Alarm Initiation and Broadcast Capabilities
Each SmartSeries® Control Cabinet is equipped with a primary and a backup audio generator,
programmed with pre-recorded tone and speech messages. Alarm initiation can occur at any of
the Local or Master Control Panels.
Via Monitored Input Modules (MIMs) installed in each Control Cabinet, the SmartSeries® system
interfaces to the existing fire and gas detection systems. When a contact closure occurs, the
MIM sounds a sonalert at the Control Panel, notifying the operator of a change in status. The
operator can then determine the appropriate course of action, i.e., whether to initiate an alarm, or
gather further information from personnel in the area. The MIMs also monitor the detection
system cabling for faults, including open circuit and ground fault and short circuit of each input.

Field Equipment
SmartSeries® Handset Stations are installed throughout the Formosa facility to provide party line
communications. The current system configuration does not allow any of the field stations to
generate any pages. The party line configuration is as follows:
· Party Line 1 is designated the Emergency Party Line, reserved for use in emergency
situations only. The station user simply turns to Party Line 1 and lifts the handset. A sonalert
immediately sounds at all linked Control Panel(s) to notify the operator that communication is
requested. Use of this party line would occur during emergencies to allow field personnel to
update control room operators of any changes in the emergency condition.
· Party Line 2 provides Hot Line connection to the Control Panel. Operation is the same as
the Emergency Party Line, but this party line is not reserved for emergencies. It may be
used, for example, to request that the control room operator generate a page.
· Party Lines 3 and 4 provide party line communications within each subsystem only.
· Party Line 5 will provide sitewide communication after the SmartStatus Display Server is
installed and commissioned.
SmartStatus Display Server
The SmartStatus Display Server links the 8 subsystems for exchange of data and audio signals.
Via fiber optic cable, each Control Cabinet sends data, including equipment status, communication
line status, and alarm status, to the SmartStatus Display. The operator at this location is
immediately be notified of all changes to system status. In addition, SmartStatus will provide an
audio link between the four systems, permitting the Control Panel operators in each subsystem to
generate pages to some or all of the other subsystems.
