The VIGILANT Building Occupant Warning System (BOWS) is a self-
contained AS 2220 or ISO 8201 Alert and Evacuate tone generator, with
integral power supply, speaker line supervision, digitised speech
messages and PA microphone. It has been designed to connect directly
to a fire alarm panel, but can be alternatively used stand-alone.
A block diagram of the BOWS is shown in Figure 1.
Figure 1. BOWS Block Diagram
The BOWS has a microphone for emergency public address, fault and
status indicators, and an Evacuation Control key switch to select its
operating mode. It has audio inputs for background music, remote audio
(which can be used when streaming audio over IP networks), and non-
emergency paging (zone-selective with an add-on option).
The BOWS has a 24V 5A power supply / battery charger compatible with
17Ah batteries.

The VIGILANT BOWS is available in two standard configurations:
FP1021 single 50W audio output.
FP1022 single 100W audio output.
Figure 2. Figure 3.
1 x 50W output (FP1021) 1 x 100W output (FP1022)
The FP1021 50W BOWS may be upgraded in the field by adding a
second T-GEN 50 to provide a second 50W output.
The FP1022 is fitted with a master T-GEN 50 and a slave T-GEN 50, with
the outputs arranged in a bridge configuration to provide a single 100W
output.
Note: it is not possible to convert a FP1021 50W BOWS to an FP1022
100W BOWS in the field.
The BOWS can optionally be fitted with a speaker distribution module
(SDM-4) which allows the single 100V 50W/100W output to be split into
four separately selectable 100V line outputs. Each output has separate
line supervision (o/c & s/c). The SDM-4 will isolate a shorted output
allowing the other outputs to operate. Each output is rated at 40W max.
The total load cannot exceed the BOWS rating (50W or 100W).

Operation of the BOWS is controlled by the Evacuation Control 003 key
switch. In the “AUTO” position the Alarm input (ALM-) is enabled. In the
“ISOLATE” position the Alarm input is disabled and any latched fault or
alarm conditions are reset. In the “EVACUATE” position the Evacuate
tone is generated.
In Auto mode activation of the Alarm (ALM-) input starts a six-stage rising
amplitude Alert tone. This continues until one of the following occurs:
-the Alarm input returns to normal (Alarm input in non-latching mode),
or
-the Evacuation Control switch is changed to Isolate, or
-the Evacuation Control switch is changed to Evacuate, or
-the Alert to Evacuate change-over time is reached.
If the Alert to Evacuate change-over time is set to 0 sec, then no Alert
tone is generated and the Evacuate tone is generated immediately. If the
change-over time is set to Alert only, no Evacuate tone is generated and
must be initiated manually. Alert and Evacuate voice messages are
automatically inserted in the Alert and Evacuate tone sequences
respectively. Messages shorter than 0.5 seconds are not inserted.
Generally with the Evacuation Control switch in the “AUTO” position the
operation of the BOWS is controlled via the ALM- input from the fire
panel.
A test mode is provided for testing the 100V line and speakers. To
activate this put the BOWS into Auto and fit the Test Link (LK4) on the
(master) T-GEN 50. The BOWS will produce a short 500Hz tone burst
every 4 seconds at low volume (-30dB).
If the 100V line is overloaded (e.g. short circuit), the BOWS will shut
down its amplifier output until the fault is removed. Detection of an open
or short circuit on the 100V line output will also cause a fault condition.
If the Alarm input fault supervision is enabled, an open circuit on the
ALM- input will cause a fault condition.
These fault conditions will turn on the Audio Fault indicator and activate
the Fault output. Note that the 100V line is not supervised for the first 60
seconds after power up to allow the monitoring capacitors to charge up.
Note that the BOWS fault outputs are put into the fault state when the
BOWS Evacuation Control switch is in the “ISOLATE” position.

The BOWS contains four digitised speech messages, defined as Msg1,
Msg2, Alert and ISO 8201 keywords. Refer to the Recorded Message
table in the Configuration section for the actual pre-recorded phrases.
The BOWS will play the alert message during alert, Msg1 (or Msg1 +
Msg2 if recording is longer than 4 seconds) during AS 2220 or ISO 8201
Evac if SW8 is off, Msg2 during AS 2220 if SW8 is on, and just the
ISO 8201 keywords during ISO8 201 if SW8 is on.
The operator may use the PA microphone for emergency public address.
This is activated when the microphone‟s PTT button is pressed while the
Evacuation Control switch is in either the AUTO or EVACUATE position.
Emergency PA overrides the Alert and Evacuate tones.
The BOWS supports remote paging using the A4485 4 zone paging
console (Figure 8).
To use this feature the FP1023 BOWS ZONE PAGING KIT option
(includes an SDM-4 and Paging Console) must have been installed.
The A4485 paging console has the following controls and indicators
(Figure 8):
Talk switch Off Microphone is turned off
Page Microphone is turned on (turns off when
released)
Lock On Microphone is turned on
Zone Select switches Push to select / deselect a zone
A blue indicator on the button is turned on
when the zone is selected
All Call Selects all 4 zones
Cancel Deselects all zones
Busy (indicator) Turned on if the console is not ready for
paging
Operation
Select the zone or zones to be paged using the zone select buttons
on the paging console.
Move the talk switch on the console forward to the Page position.
Make the announcement and then release the talk switch.
Paging can be configured to override, or not override, the Alert/Evacuate
tones. If configured to not override tones the paging will operate only
when the BOWS is not in Alarm and the Evacuation Control switch is in
the AUTO position (e.g. not generating tones).
If configured to override tones the paging will also operate when the
BOWS is in Alarm or the Evacuation Control switch is in the EVAC
position (e.g. generating tones). In this mode the paging console will
operate in a similar manner to the emergency PA microphone and
announcements will be automatically broadcast to all zones overriding

the tones. Note that the operator must still select at least one zone on the
paging console to activate the microphone.
The A4485 paging console has a pre-announcement chime option that
can be selected via a DIP switch located at the rear of the console. Refer
to the A4485 Paging Microphone Operating Instructions supplied with the
console for further details.
The BOWS supports selectable paging of up to 4 zones using the BOWS
emergency PA microphone.
To use this feature the FP1024 BOWS EMERGENCY MIC ZONE
PAGING KIT option (includes an SDM-4) must have been installed.
Operation:
Select the zone to be paged using the PAGING ZONE SELECT
switch (Figure 9).
Make the announcement using the BOWS Emergency PA
microphone by pushing the microphone‟s push to talk button.
Zone-by-zone paging is available only when the BOWS is not in
Alarm and the Evacuation Control switch is in the AUTO position. If the
Emergency PA microphone is used when the BOWS is generating tones
the PA announcements will be broadcast to all zones, irrespective of the
Paging Zone Select switch position.

The BOWS has a 3.5mm audio jack and screw terminals for connecting
an external background music audio source to the BOWS. The
background music will play whenever the Evacuation Control switch is in
the AUTO position, the BOWS is not generating tones, and no other
audio source (such as the emergency PA microphone or paging console)
is being used.
The BOWS has a 3.5mm audio jack and screw terminals for connecting
an external remote audio source to the BOWS. The remote audio input
has an Active input signal, which must be activated by the external audio
source to broadcast the audio. The remote audio input can be configured
to either override the T-GEN tones (similar to the emergency PA
microphone) or not override tones (similar to the background music
input). This input has been designed to be compatible with the BARIX
range of audio-over-IP devices. Refer to the IP Networking Using Barix
Modules section later in this manual.

When an audio source is configured to „Override Tones‟ the audio source
is fed into the T-GEN PA Mic input, and therefore the output level will be
determined by both the volume control on the BOWS Interface board and
the PA VOL (VR3) on the master T-GEN 50. It is therefore recommended
to set the master T-GEN Emergency PA Mic level (VR3) first (if required)
before adjusting the volume controls on the BOWS Interface board.

The BOWS supports 2 recordable messages, Alert and Evac. Alert can
be up to 4 seconds long. Evac consists of two factory-programmed
messages (Msg1 and Msg2) that can be up to 7.2 seconds in total
length. The Alert and Evac messages can be re-recorded using the
Emergency PA microphone.
To record a message use the following steps (when the BOWS is not in
alarm or evacuate or test mode):
1. Fit link LK3 - REC EN on the T-GEN (master). This enables the
recording and playback of messages.
2. Select the message to be recorded (played) using switch 2 - T1 as
follows:
T1 Off - Evac message T1 On - Alert message
3. Press the Emergency PA microphone button to start recording.
Recording will continue until either the button is released or the
maximum message length has been reached (see NOTE).
4. The recorded message can be played back using the Play button
on the T-GEN board. Note that if the Evacuation Control switch is
not in the Isolate position the played back message will be
broadcast over the speaker system. Recording is not broadcast.
5. When recording has been completed, re-set T1 to its original
position and remove Link LK3 to disable the record function.
NOTE: Messages less than 0.5 seconds will not be broadcast (this
can be used to delete an unwanted message). Note that if
Evac Msg1 is replaced with a message of more than 4
seconds duration, Evac Msg2 will also be overwritten.
If the BOWS is fitted with a slave T-GEN 50 (e.g., 100W BOWS or 50W
BOWS fitted with a 2nd T-GEN), the switches on the slave T-GEN are not
used and should be left in the Off position. The links must be set in the
following positions (NF = Not Fitted): LK1 –NF, LK2 –NF, LK3 –NF,
LK4 –NF, LK5 –SLAVE, LK6 –SLAVE, LK7 –DEF-.
