CHAPTER 1 SYSTEM DESCRIPTION & SPECIFICATION
1.1 OVERVIEW
The Vigilant MICROVAC is a self-contained single zone emergency warning system
designed to facilitate the orderly evacuation of a zone in the event of an emergency.
Microprocessor-based, MICROVAC has been designed to perform the functions specified by
Australian Standard AS2220.1 (1989) for emergency warning systems in buildings. When
used in a standalone mode it contains no facilities for the emergency intercommunication
system requirements of AS2220. These are an option in networked systems.
The MICROVAC emergency warning system generates the emission of audible warning
signals throughout the zone via loudspeakers. In areas where the background noise level is
high, the loudspeakers can be supplemented by the use of visible warning strobe lights.
Two standard 25W versions are available, wall mounting (FP0530), and rack mounting
(FP0533). The rack mounting version is designed for integration within a Fire Panel, and to
use the Fire Panel's power supply.
In addition models are available with integrated 100W or 200W booster amplifiers.
All models may be supplied with or without networking facilities. Networking enables a
Microvac to be integrated with a QE90 system and controlled by one or more QE90 ECPs.
The product line-up and part numbers are given below.
Networked Power Mounting Part
Number Size H*W*D (mm)
No 25W Wall FP0530 555*380*125
No 25W Rack FP0533 133*483*275
No 100W (1.5A PSU) Wall FP0626 440*550*211
No 100W (6A PSU) Wall FP0598 440*550*211
No 200W (6A PSU) Wall FP0599 750*550*211
Yes 25W (1.5A PSU) Wall FP0762 750*550*222
Yes 100W (6A PSU) Wall FP0763 750*550*222
Yes 200W (6A PSU) Wall FP0764 885*575*380
WIP facilities can be added to the networked versions in two ways (separately or combined).
Firstly a single WIP can be connected to the ECM module and used as a WIP for that zone.
Picking up this WIP will automatically call the programmed ECPs in the system. The WIP
may be called from these ECPs.
Secondly an 8 circuit WIP module (or more depending on the cabinet size) may be installed
in the Microvac to provide up to 8 field WIPs. In addition a WIP connected to the ECM
module may be used as a Master WIP. All these WIPs may be called from designated ECPs
in the network, and may call to these ECPs. Calls from the field WIPs may in addition be
answered by the Microvac master WIP. However as there are no WIP controls at the
Microvac it is not possible to call the field WIPs from the Microvac master WIP.

1.2 SYSTEM CONCEPT
MICROVAC is a single zone EWS unit, contained in a wall mounting cabinet with the
electronic functions located on a two PCBs, the Main PCB and the Keyboard/Display PCB.
High Powered versions and networked versions contain additional PCBs.
Figures 1.1 - 1.4 show block diagrams of the various MICROVAC control units.
The Main PCB provides tone generation, visual alarm output (strobes), 100V line output, FIP
and BGA inputs, auxiliary control inputs, auxiliary audio inputs, and BGM attenuator
override and fault relay outputs.
The Keyboard/Display PCB provides the switches and LEDs for the front panel.
A microprocessor located on the Main PCB handles all control tasks. In AUTO mode it
monitors the FIP and BGA control inputs for activation. If one is activated then the beeper
will sound and if an "Initial Delay Before Alert" has been set this delay will occur and then the
ALERT tone(and optional speech message) will be generated on the 100V speaker lines and
the ALERT strobe output will be activated. This will continue for the "Alert to Evacuate
Delay" time, then the EVACUATE tone and speech message will be generated, and the
EVACUATE strobe output will be activated.
At any time, MANUAL mode may be selected from the front panel, and ALERT, EVACUATE
and PA may be manually controlled.
The warning signals are prioritised so that PA Speech is highest, Evacuate next highest, and
Alert lowest.
The microprocessor also monitors the control inputs, speaker lines, strobe lines, and the
amplifier and battery charger for fault conditions.
Non emergency functions of Paging and Background Music are also provided. These are
over-ridden in the event of an emergency.

CHAPTER 2 INSTALLATION, WIRING, SETUP &
COMMISSIONING
2.1 INSTALLATION
The MICROVAC control unit should be mounted on a wall in a location convenient to the
provision of:
- 240V Mains
- Speaker & Strobe Cabling
- FIP and BGA interconnection cabling
- BGM and PAGING interconnection cabling if required
- Easy Operation
- It is desirable to allow the door to open fully to allow easy access inside the cabinet.
2.2 WIRING
2.2.1 MAINS
240V Mains wires into the unit via one of the cable entry holes in the top or bottom of the
case.
Mains earth terminates on the earth stud and phase and neutral on terminals 2 and 3 of the
Mains ON/OFF switch respectively. On models with a PSU2406 fitted, mains connects to the
mains cord fitted to the PSU2406.
2.2.2 BATTERIES
For the FP0530, FP0533, and FP0626 (which use the Microvac main board PSU) a 24V
battery must be connected to screw terminals J5 and J6.
J5 Battery +ve
J6 Battery -ve
For the remaining models (which use a PSU2406) a 24V battery must be connected to the
battery leads of the PSU2406
Red Battery +ve
Black Battery -ve
2.2.3 AUXILIARY 24V OUTPUT
The internal 24Vdc supply is available on screw terminals J7 - J10:

Installation, Wiring, Setup, and Commissioning
Page 2-2 5 April 2000 Issue 1.31
2.2.4 FAULT RELAY OUTPUT
The fault relay output is available on screw terminals J21, J22 and J23. It is normally
energised and drops out on the existence of one or more fault conditions in the MICROVAC
control unit or its monitored lines. The relay contacts can be used to send the fault condition
to a monitoring system or other annunciation device.
The contacts are rated at 1A @ 30Vdc and any external relay or inductive load must be
clamped for transient suppression.
J21 Fault Relay Normally Open
J22 Fault Relay Normally Closed
J23 Fault Relay Common
Note The relay is normally energised so the NC terminal will be connected to common
when a fault is present.
2.2.5 STROBE OUTPUT
The strobe output must be terminated with either a 2k7 resistor (factory fitted) or with an
STBT9008 Strobe Terminator module (Part number PA0668) if strobe lights are to be used.
The strobe line is monitored for short and open circuit faults, thus the need for the end of line
device.
The wiring for the strobe output is shown in Fig 2.2.
The cable size should be selected so that minimal voltage loss occurs in the cable during
strobe activation. The maximum current is 0.9A and cable voltage drops should be kept
below 1V.

line.
2.2.6 BGM OVERRIDE RELAY OUTPUT
A BGM override relay output is provided to control remote level attenuators that may be
used to reduce the volume when background music is active.
These attenuators must be by-passed when the Alert, Evacuate, PA Speech, or (non-
emergency) Paging functions are selected.
The relay contacts are rated at 1A @ 30Vdc and any external relay or inductive load must be
clamped for transient suppression.

2.2.7 ALARM RELAY OUTPUT
An Alarm relay output is provided to indicate that an active FIP or BGA alarm input has been
detected.
The relay contacts are rated at 1A @ 30Vdc and any external relay or inductive load must be
clamped for transient suppression.
J18 Alarm Normally Open
J19 Alarm Normally Closed
J20 Alarm Common
Note The relay is normally not energised so the NO terminal will be connected to common
when one or both of the FIP or BGA inputs is in alarm.

2.2.8 FIP AND BGA INPUTS
The FIP and BGA inputs are designed to be connected to the Fire Panel and one or more
Break-Glass-Alarm switches respectively.
A 15k End-Of-Line resister must be fitted in both cases to allow open circuit fault monitoring.
In addition, it is optional to include short circuit fault monitoring. This is controlled by DIP
Switch 2:2. If ON, short circuit is alarm, if OFF short circuit is a fault and the alarm condition
is obtained by terminating in a resistance of 7.5k. (i.e. a resistance of 15k in parallel with the
EOL resistor.)
Note the switch 2:2 position applies to both the FIP and BGA inputs.
The wiring for the FIP input is shown in Figure 2.4, and the wiring for the BGA input in Figure
2.5.

BGA INPUT WIRING
Note: FIP and BGA contacts should close to operate the alarm function.
In the case where short circuit fault monitoring is used, no more than 4 switches +
resistors may be connected in parallel.
2.2.9 PAGING CONTROL INPUT
To enable the (non-emergency) paging function, it is necessary to connect a switch to
connections J28 and J29 on the MICROVAC, and the switch should be wired so that closure
indicates that the Paging function is active. This will enable the PAGING audio input
provided no emergency functions are active.
If a 15k resistor is connected across the paging control inputs, the AUX audio input will be
selected. This could be used for secondary paging, a second channel of music, etc.
2.2.10 BGM / AFTER HOURS CONTROL INPUT.
The function of the BGM / After hours input depends upon the setting of DIP Switch 2:6. If
this switch is ON, a contact closure between Connectors J30 and J31 on the MICROVAC
will enable BGM.
If DIP Switch 2:6 is OFF, BGM is always selected provided no higher priority function is
active, and the input functions as follows -
(a) 6k8 ohm resistor connected across terminals:
This selects the "After Hours" mode of operation, i.e. any Alarm (FIP or BGA)
will cause the MICROVAC to immediately generate the EVACUATE tones
and speech, bypassing the ALERT phase and any "Delay before action"
which may be set.
(b) Short circuit briefly connected across terminals:
This will switch on the Alert signal for a duration of 10 minutes while the
MICROVAC is in Automatic.
(c) Nothing connected across terminals:
Normal Operation.
The wiring for this mode is shown in Figure 2.6.

2.2.11 BGM, PAGING AND AUX AUDIO INPUTS
Balanced line audio inputs are provided for background music, non-emergency PAGING and
a further auxiliary function (AUX input). The signals are selected as described in 2.2.9 and
2.2.10.
The devices generating the background music, paging, and AUX should provide between
0.3 and 2.0 VRMS at the input terminals. Volume control can be individually achieved with
the AUX pot VR3, Paging pot VR4 and BGM pot VR5 respectively.
Note the OUTPUT volume pot VR1 should be set to provide the required Alert/Evacuate
level first and then the BGM, Paging, and AUX levels set afterwards.
2.2.12 100V SPEAKER LINE
Wiring of the 100V speaker line should be carried out using cable of adequate cross-
sectional area to keep the voltage drop over the required length to less than 5%.
As the line is DC monitored for open and short circuit conditions, each speaker needs to be
capacitively coupled so that the matching transformer resistance does not upset the DC line
monitoring. A capacitor of between 1uF and 5uF per watt of speaker power should be used
at each speaker. The capacitor should be a bipolar type and have a voltage rating of 25V or
more.
For example if only one speaker of 25 Watts is used, a 33uF 25V Bipolar capacitor could be
used. If 10 speakers each rated at 2.5 Watts are used, then a capacitor of 3.3 - 10uF, 25V
should be used at each speaker.
The end of the speaker line must be terminated with a 56k resistor.
If it is desired to have two branches on the speaker line, it is necessary to use an EOL
resistor of 150k on each branch, since 150k is a fault condition and two 150k resistors in
parallel (75k) is a normal condition.
Wiring of the speaker line is shown in Fig 2.8.

2.2.13 EXTERNAL DC POWER INPUT
The Rack Mounting Microvac is intended to be powered from the FIP DC power supply. The
standard Microvac can also be powered from an external DC supply if one is available and
Mains is not.
The 24V DC supply from the FIP should be connected to J5 (Battery +ve) and J6 (Battery
-ve). There are two options available regarding the monitoring of this supply -
1. Disable monitoring of this input and the Mains input by switching DIP switch 2:7 ON.
This option can be used if the supply is fully monitored by the FIP.
2. Enable monitoring by switching DIP switch 2:7 OFF. In this case it is essential that
the DC voltage is always between the Charger High and Charger Low voltages as
detailed in section 1.3 Specifications and temperature compensated at -36mV per °C,
otherwise faults will be indicated.
If you connect a wire from J5 (Battery +ve) to either of the 27V AC terminals, then the Mains
On LED will illuminate, and Mains Failure will not be indicated as a fault (option 2).
Alternatively, the Microvac could be powered by its own PSU, for example a PSU2406 or
PSU308. If one of these is used then it should be wired as shown in Figure 2.9. DIP Switch
2:7 should be ON, enabling monitoring. Any fault in the power supply will then indicate as a
Mains Fail Fault on the Microvac.

2.2.14 VIGILANT HIGH POWER AMPLIFIER WIRING
This applies to 100W and 200W Microvacs purchased after 1 June 1999. For older models,
refer to the Issue 1.2 manual supplied with them.
100W and 200W Microvacs supplied by Vigilant will be wired in the factory. The 100W or
200W output is taken from the fitted transformer module, HTRN9308 or TRAN200. On all
models except the 1.5A 100W FP0626, an additional 25W output is available on the speaker
terminals J46 and J47 of the Microvac Main board.
The output level should be adjusted with the level control on the Microvac, and the level
control on the HAMP9308 or AMP200 left in its maximum position.
2.2.15 THIRD PARTY BOOSTER AMPLIFIER WIRING
This has been tested with an Audio Telex SA250B 250 watt booster amplifier. This is not an
endorsement of that amplifier by Vigilant, or an indication that similar amplifiers from Audio
Telex or another manufacturer will be suitable. Vigilant has not tested any amplifiers for
compatibility with AS2220.
A suggested arrangement for powering the Microvac and a booster amplifier from a
PSU2406 or PSU308 is shown in Figure 2.10.
