Introduction
Voice Alarm (VA) systems are the quic est way to evacuate the public & staff
from a building.
Following fire detection, automated messages control the flow of people in
stairwells and corridors allowing an orderly evacuation without panic. These
messages are supplemented by spo en messages from the fire service or
management suite confirming the validity and need to leave the building.
This positive confirmation speeds evacuation and avoids the "false alarm"
mentality reducing the ris of death from fire.
Suitability
Voice Alarm systems are recommended for all public buildings and multi story
buildings over four floors by BS5588.
In public buildings it's not possible to fire drill the public, as they visit the
premises infrequently, so systems such as Voice alarms save valuable time in
evacuating the building.
The use of phased messages in multi-story buildings prevents over-crowding in
stairwells and at exits, preventing secondary injuries. In phased evacuation, the
floor in fire receives the evacuate message, and the floor above & below receive
an alert message, preparing them for evacuation.
In more complex scenarios the use of multiple alert and evacuate messages can
be beneficial, messages telling the evacuees they are going the right way, and
messages as ing people to ma e way for people leaving evacuated areas. These
additional messages can dramatically speed up the evacuation especially in malls
and large airport environments.
verview
For small and medium sized installations this self-contained voice alarm controller
provides an ideal solution.
The basic controller has 4 monitored outputs, and the following inputs: 2 all call
fire microphone ports, a data control port for networ ing & configuration, 2 four
zone high priority microphone ports, 2 digital message slots (allowing four
messages to be held in hardware), a six input fire alarm interface with common
de-latch input (24V voltage inputs for connection to sounder circuits), 2 low
priority zoned microphone ports, and three stereo music inputs.
The front panel LCD allow selection of volumes, music sources and configuration
of all functions, as well as providing access to the 99 event log. In the event of
processor failure the 2 fireman’s inputs can access the whole system in line with
EN60849 and BS5839 pt 8.
Standards Compliance
The @udio Logistics ALP48 complies with all the relevant current Voice Alarm
standards including BS5839 parts 1,4 & 8 and EN60849.
We are also monitoring the meetings of the EN54-16 committee to ensure we will
comply when this is released.
Additionally the ALP48 complies with the EMC requirements of EN55103-1 and
EN55103-2.

Navigating the ALP48 Menus
All functions of the ALP48 can be configured using the front panel LCD and the
three navigation Keys (LEFT, RIGHT, and ACCEPT), abbreviated to <L) for LEFT,
[A] for ACCEPT and (R> for RIGHT.
When the ALP48 is powered up, it will always revert to the Root Menu.
General Menu Format
When [A] is pressed for the first time from the root screen, the display will show
as follows
ALP v3.8-User
Back
>View audio sources
View fault status
The top line shows the panel type with version number and the menu level. The
next 3 lines show various menu options: the current option, the preceding option
and the following option.
The first menu option will become the current menu option if <L) is pressed.
The second menu option will always be prefixed by a right chevron ‘>’. This
indicates the current menu option. Pressing [A] will ta e you to this option.
The last menu option will become the current menu option if (R> is pressed.
When in a configuration menu, a variety of options may be displayed. Each
option will either have a colon ‘:’, or a chevron ‘>’ followed by the value for that
option, e.g.
Net address>1
The chevron will indicate which option is currently selected. Use the <L) and (R>
buttons to toggle through the various values for that option. When the correct
value is chosen, press [A] to move to the Next option.
Each configuration screen will have an option in the bottom right. By default, this
option will be Next. The different values for this option are:
Next: moves cursor bac to first option on this page, or to first option on
next page if there is more than one page
ave: saves the new configuration, and moves bac to the menu list.
Quit: discards any changes made, and moves bac to the menu list.
Inputting Text
All text input on the ALP48 uses the same technique. The text to be edited either
begins with a right chevron ‘>’, or is brac eted by chevrons ‘>’ and ‘<’. The
number of characters allowed depends upon the text being edited.
For example,
Edit fault text
Fire microphone 1

ALP48 Programming Manual

Monitor DCA4 fault
This menu enables the ALP48 to monitor all DCA4s for specific faults. This
enables the ALP48 to only show the specified faults in the fault log. To enable
monitoring for that fault, toggle the value to Y.
As there are 10 DCA4 faults that can be monitored, the display is split into 3
pages. To move to the next page, press [A] when the cursor is on Next.
The ALP48 receives regular status reports from the DCA4, including all faults
current on that DCA4. If the DCA4 reports a fault, and the appropriate
monitoring is enabled, then that fault is added to the event log.
