EXIGO Functions
Exigo is designed to meet the requirements of a wide variety of applications. To be able to solve the needs of the operators a set of functions have been made which ensures that the operator is able to control the PA system at all times.
Input functions can be assigned any button or control input in the system and can control activities in any part of the system. Output functions can be assigned to any control output in the system and will trigger based on the activity in the system.
PA functions
The Exigo Advanced IP based PAGA system is designed to solve all the operational requirements for a PA system used for PA, GA, EVAC or similar. To ensure this a wide variety of audio announcement functions and supporting functions are supported:
- Alarm control: Control the audio alarms in the system.
- Audio program control: Control the background music or analog audio routing path from any line input to one or more zones of the system.
- Live speech: Activate a live announcement from a call panel to one or more zones in the system. This function can be preceded by any chime and have any priority of the system. One call access panel is capable
- Message control: Trigger a pre-recorded message to any zone. With a selectable priority, this can be used both to trigger emergency messages and to trigger a low priority information message.
- Recall, record and Recall, control: Record a message on the fly from a call panel and check it before dispatching it to a zone.
- Zone select: Select which zone an announcement should be sent too. This can be used before triggering any function such as live speech or message control too dynamically select the zone, which should receive it.
- Call escalation: Change the operation of any function in the system. Change chime, priority or even which zones a push to talk button will activate.
- Local mute control: This will manually trigger muting relays used on speakers in control rooms. A typical use case for this is to mute the speakers in control rooms and bridges during alarm situations. When the alarm situation is over the mute relay will go back to the idle position.
Input Functions
Ensuring the operation of the PA system is more than being able to send out an announcement. Many supporting functions will ensure that the operator can be confident that the public address and alarm system is available and ready for when it is needed:
- Line measurements: Manually trigger line monitoring of the amplifiers. The line monitoring of the amplifiers can also be continuous, ensuring that the speakers are functional at all times.
- External fault: This function can be used to get fault status for external systems into the Exigo systems. A typical use here is to monitor external power systems or external alarm systems, which are critical for the PA system.
- Microphone test: This function can be used to test the microphone on the call stations which have an embedded speaker such as the ECPIR-3P. The operator can activate this function and say something into the microphone and the call panel will send the audio back to the system controller which will return it to be played on the speaker, thereby ensuring the consistency of the signal path and audio signal components.
- Remote activation of microphones: Remote activation of microphones can be used to activate microphones on lifeboat stations or similar. This will test the microphone and send the audio back to the activating panel without activating the full access panel.
- Panel Lamp test: This function will enable all leds on the access panel so that the operator can ensure that the leds are functioning correctly.
- System status: This function can be assigned to buttons with a red and green led and is usefull when there are more than one controller active, such as in AB systems. The red led will indicate if there is a fault while the green led will indicate if the access panel is connected to the system controller or not.
- Tick tone control: This function can activate a tick tone in a complete zone so that the operator can ensure that all the speakers are working. For AB systems the tick tone in A and B can be different and ensure that the zone can be checked in one go.
Output functions
Many Exigo devices have a set of control outputs, which can be used to integrate with external systems – such as analog phone systems, flashing light systems or external monitoring systems such as SAS. These outputs can have a set of output actions with various parameters:
- Audio activity: This function can be set up to trigger on any combination of activity in zones, priority range or sources. Sources can vary from following a specific alarm to a specific audio program being active. The audio activity function is so flexible that it can be set up to trigger on a specific type of audio being queued.
- Fault indication: This will activate when there is a specific fault or fault type active in the Exigo system.
- Follow alarm tone: Follow alarm tone will follow the alarm generated from the digital alarm generator embedded in the system controller. This is useful for ensuring that flashing lights are activated in sync with the alarm when the alarm is activated in noisy areas as an example.
- Local mute: Local mute is used to activate an output connected to a mute relay used to mute a speaker. This is used to prevent audio feedback in areas where the call panel is placed close to the speakers.
- Volume override: The volume override function is used to ensure that analoge volume controllers are fail safe in the system. These volume controllers should be active for as long as there are audio below a set priority in the system or that the amplifier is operational.
1. Assigning an audio activity function to a control output
2. Selecting a specifc fault for the external fault function to trigger on
3. Adding a zone select function to a button on an access panel
