VAR4 / VAR12 / VAR20 - Product Description
3.2.2 Digital Voice Announcers
Digital Voice Announcer (DVA) messages are divided into two types:
• Long DVA: up to 32 second message length
VAR4 provides storage for 2 Long DVAs
VAR12 provides storage for 4 Long DVAs
VAR20 provides storage for 6 Long DVAs
• Short DVA: up to 16 second message length
VAR4 provides storage for 2 Short DVAs
VAR12 provides storage for 4 Short DVAs
VAR20 provides storage for 6 Short DVAs
The DVAs may be configured so that they either stop immediately, part way through a message when
terminated, or can be configured to play the message to the end.
The DVAs are usually controlled by VAR Router contact inputs, which interface to a Fire Alarm panel. Any
VAR Router contact may be assigned to this function. Two modes of operation are supported:
• Latching: the trigger is latched by the VAR Router. This requires a separate reset input from the Fire
Panel to terminate the route.
• Non-Latching: a reset signal is not required. The route is terminated when the trigger ends.
The DVAs may be also routed by the Permanent Route mechanism described in Section “Permanent
Routes”.
3.2.3 Background Music
The two phono Music inputs (Music A and B) maybe be routed by two means:
• Permanent Route: typical for background music.
• Latent Route(s) activated by contact closure. A separate contact may be specifically assigned as a
music selector to switch between either Music A or Music B sources.
L
Additional music sources may be connected to any Mic/Line input configured as a
Miscellaneous Input.
3.2.4 Mute Input
The VAR Router provides a special ‘Mute’ 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.
