ESCRIPTION
The Vigil 3 Amplifier range consists of modules containing 2 or 4
amplifier blocks.
The following Vigil 3 amplifier modules are available;
• BV75D - 2 x 75W Amplifier Blocks
• BV150D -2 x 150W Amplifier Blocks
• BV300D - 2 x 300W Amplifier Blocks
• BV75Q - 4 x 75W Amplifier Blocks
• BV150Q - 4 x 150W Amplifier Blocks
Vigil 3 Amplifiers contain a built in mains PSU and when
combined with a BVMBC Battery Charger Module form a
complete EN54-4 compliant Battery Backed power supply
system.
The audio input for each amplifier is presented on two separate
RJ45 connectors.
Each amplifiers output is presented on a single 2-way plug/cage
clamp termination connectors providing 100V output.

Vigil 3 Amplifier Installation Manual issue 1
The Amplifier Module Mains Input is presented on a standard IEC
connection and the 24V DC input (battery connection) is
presented on a two 2-way plug/cage clamp termination.
In addition there is a single RJ45 AUX Output for connection to
the BVMBC battery charger module.
The power output stage of the amplifier is protected against
overload conditions (i.e. short circuits or abnormal loads).
Should an amplifier be subjected to an abnormal load the input to
the relevant power amplifier is attenuated to a safe level. The
amplifier output voltages are also sensed and should they exceed
100V the relevant input signal will be attenuated ensuring safe
operation without creating unnecessary distortion.
Over temperature protection is provided using sensors attached
to the module heat sink. Should the temperature exceed 70C an
Over Temperature fault is indicated and if it exceeds 75C the
input signal to the relevant amplifier will be attenuated to a safe
level.
If the system is under surveillance it will cause the surveillance
detector to indicate a fault condition due to the gain reduction.
Each amplifier block has status LED’s on the front panel consisting
of an OK/FAULT LED and a 10%/100% LED.
The OK/FAULT LED indicates the following;
• Steady Green - OK
• Flashing Green - PSU Fault, no 24V or mains present
• Yellow - Overload or Over Temperature Fault
The 10%/100% LED indicates the following;
• Off - No signal output
• Green - 10V signal output
• Yellow - 100V signal output

2 Installation Examples
The Vigil 3 Amplifiers have been designed for quick and simple
connection and configuration.
The individual amplifier blocks can either be used as independent
amplifiers, can be one of two amplifiers wired as an A-B Dual
Circuit using a single input signal, or the 300W amplifiers can be
paralleled with other 300W Vigil 3 Amplifiers to enable higher
power outputs (up to a maximum of 4 Vigil 3 300W amplifiers
giving a total of 1200W).
The amplifier blocks have two paralleled input connectors to
enable simple interconnection using standard RJ45 patch leads.
The 100V Line output connectors are “cage clamp” type as this
type of connector is more reliable than screw terminals.
N
OTE
: Where possible when A-B circuits are used it is recommended that
A and B circuits are connected to amplifiers in serperate modules. This is
due to power supplies, mains connections and battery connections being
shared by amplifiers inside a module.
N
OTE
: Where possible when reserve amplifiers are used it is recommended
that reserve amplifiers should be located in a different amplifier module
to the primary amplifier. This is due to power supplies, mains connections
and battery connections being shared by amplifiers inside a module.

In order to use the Vigil 3 amplifiers with a BVMBC battery
charger module the AUX output connection of up to 5 amplifier
modules must be connected to the BVMBC. For more

Breakers
Flashing 24V or Mains Supply Failed Remove 24V supply if LED
extinguishes then fault is with
mains supply. Check mains
supply as above.
Remove Mains Supply if LED
extinguishes then fault is with
24V supply. Check battery
connections as above.
If both Mains Supply and 24V
supply are present at the
amplifier module then it has
failed and must be returned
for service.
Yellow Overload or
Overtemperature Fault
Disconnect speaker lines, if
LED returns to Green then
either the speaker lines are
overloaded or shorted
Disconnect speaker lines, if
LED remains yellow then an
overtemperature fault has
occured. Allow amplifier
module to cool and check
cooling fans.
