EVENTS CONTROLLED BY "GPI" INPUTS

Each IO 3250 digital INPUT/OUTPUT board is equipped with 16 opto-insulated inputs which can be specifically driven to control various
events. These inputs are identified in the various menus of the CP 3100 control unit with the name GPI inputs (see the section GPI INPUTS).
The following types of events can be controlled by the GPI inputs (max. 256 events).
• switching of one or more relays of the IO 3250 digital INPUT/OUTPUT boards (see the section PROGRAMMABLE RELAYS), the contacts
of which can be used as desired.
• transmission of an audio signal (e.g. message, pre-announcement/alarm tone, etc.) stored on the hard disk of the CP 3100 control unit (au-
dio files) to specific zones and/or groups of zones, and eventual switching of one or more relays of the IO 3250 digital INPUT/OUTPUT
boards.
• transmission of an announcement using the microphone of the BM 3604 console to specific zones and/or groups of zones, and eventual
switching of one or more relays of the IO 3250 digital INPUT/OUTPUT boards.
• control of the FIREMAN 1 and/or FIREMAN 2 alarm events, for transmission of the "fireman" audio signal with absolute priority and even-
tual switching of one or more relays of the IO 3250 digital INPUT/OUTPUT boards.
• control of pre-announcement signals on the CP 3100 control unit.
To drive the inputs of the board, normal electrical contacts can be used (e.g. contacts of pushbuttons). To program the events controlled by
the GPI inputs, see the section USING THE "GPI EVENTS DEFINITION" MENU.

TIMED EVENTS

By means of a dedicated menu on the CP 3100 control unit, the system allows the programming of "timed events"; i.e. events that must take
place at a preset time. A maximum 64 timed events can be programmed in the system.
A timed event can control the following actions:
• switching of a relay with normally open contact of the IO 3250 digital INPUT/OUTPUT boards.
• switching of a relay with normally closed contact of the IO 3250 digital INPUT/OUTPUT boards.
• transmission of an audio signal (e.g. message, pre-announcement/alarm tone, etc.) recorded on the hard disk of the CP 3100 control unit
(audio files) to specific zones and/or groups of zones.
To program timed events, see the section USING THE "TIMER EVENTS DEFINITION" MENU.

"VOX" EVENTS

The VOX events are controlled by the VOX devices on the OB 3230 AUDIO OUTPUT boards. See the section VOX DEVICE for a complete de-
scription of the this device.

"PLAYBACK" EVENTS

These events make use of the audio board of the CP 3100 control unit for the playback of audio signals stored on the hard disk of the
CP 3100 (audio files).
Further information on audio file playback is provided in the section AUDIO SIGNAL RECORDING/PLAYBACK.

"BACKGROUND MUSIC" EVENTS

These events enable the transmission of background music in specific audio zones. The system can handle up to eight background music
sources.

ORDER OF PRIORITY

System operation is based on the use of an order of priority, in which each system event is assigned a priority level. Depending on the type
of priority of the event, it is carried out in a certain way, as described below.
GRADUATED PRIORITY Graduated priority makes it possible for certain events to use specific system devices before events having a lower
priority level, but without the possibility to interrupt the events in progress, even those with lower priority.
The only events that can always be interrupted are those of the BACKGROUND MUSIC type.
When there are several events with different priority levels waiting to be executed due to an unavailable device, the
events with the highest priority level are executed first, followed by those with lower priority.
The scale of priority is as follows:
• Levels 1 - 8:
• Level 9:
ABSOLUTE PRIORITY This is the maximum priority, permitting certain events to use system devices before events with graduated prio-
rity, with the possibility to interrupt events in progress (override function). An event with absolute priority does
not have the override function over events of the same level; that is, it cannot interrupt other events with abso-
lute priority in progress.
Where there are events having the same priority level to be executed (absolute or graduated priority), the order of execution follows the order
of request; i.e. the first events booked are the first to be carried out.
The system devices that can be subject to priority are:
• outputs of the OB 3230 AUDIO OUTPUT boards, which can be used to drive the power amplifiers dedicated to the various audio zones of
the system.
• the audio board incorporated in the CP 3100 control unit, used for recording/playback of audio files (messages, pre-announcement/alarm
signals, etc.).
The table below indicates the respective priority level for each system event and a description of how this priority is implemented.
Decreasing priority level starting from 1 (highest priority level) to 8 (lowest priority
level).
