10 Mute Input Configuration

The Mute input is a special input, which mutes even fire microphones if needed. For this purpose its priority is set to ‘0’ by default. However, the mute input is configurable, so it is possible to mute just DVAs, and/or any other inputs on a priority basis.

The Mute input can be used for contact activated routes or DVA routing; see in Sections “

14 DVA or Route

Triggers via Contact Configuration ” and “ 14 DVA or Route Triggers via Contact Configuration ”.

The following table summarises the configurable input parameters, and indicates those parameters available for the Mute input with a tick ( 9 ). Each parameter configuration is described in the following steps.

Due to the ability of this input to mute any or all others it must be used with great care, to ensure that Fire Microphones are not accidentally muted.

10.1 Mute Input Emergency Class Configuration

The Emergency Class is only relevant in networked units, and is used by Fire Microphones connected to the

VAR8-ACU to indicate the emergency DVA message status of the zone group configured for a zone select button via its red and green LEDs. See Section “

8.2 DVA Input Emergency Class Configuration ” for further

details.

To Modify the Mute Input Emergency Class:

1. Select the Mute input.

For correct indication of the emergency DVA message status on the ACU’s front panel, as described in Section “

8.2 DVA Input Emergency Class Configuration ”, the background

music must be set to ‘Non Emergency’ as specified in the system default settings.

Changes to the system default settings may result in an inappropriate indication of the status of the zone or group of zones.
