Topic 1: VS-MKII Control System
Introduction
Designed to comply with and tested to the requirements AS 5062, the VS-MKII Control System (“MKII”)
comprises a control module, a remote display panel and audible alarm unit. The display panel provides
visual indication of system status, alarms, and faults and also allows manual extension of the equipment
shutdown delay.
Most industrial environments produce high levels of electrical noise, so the MKII has been compliance tested
to Australian Standard AS 61000.6.2:2006 for immunity to electromagnetic interference.
To minimize the effects of electromagnetic emissions from high energy sources the MKII input cables should
NOT be run parallel, or in close proximity to any cables or equipment that may produce high RF (radio
frequency) energy, e.g. cabling for RF transceiver antennas, inverters, motors etc.
Figure 1 – Typical MKII layout
All wiring and electrical connections must be installed in accordance with the customers requirements and/or
the equipment manufactures specifications. Power supply and equipment shutdown connections should
either be completed by the Customer/OEM or an approved contractor.
The MKII incorporates a rechargeable back up battery which will ensure a reliable alternative power source if
required.
The system design allows multiple configuration and programming options.

Power Supply
The MKII operates on a 24 Volt primary power supply (20-30 Volt range). If the system is installed in
equipment that uses a 12 Volt power supply, a separate voltage converter will need to be installed to boost
the voltage. The system is protected from voltage surges up to 58 Volts
Figure 4 – Control module connections
The preferred power supply arrangement for the MKII is through an isolator or ignition circuit (Fig. 5).
Figure 5 – Power connector
Primary power monitoring
•When primary power is low (<17 Volts), lost or isolated a visual and audible power fault will initiate
after 10 seconds.
•All power faults are non-latching.
•The fault reporting of over a voltage condition is masked to allow for equipment that may be prone to
power fluctuations during normal and peak operation
Input & Output Connectors
Power Connector

•When the panel receives > 31 volts for a period in excess of 10 seconds the amber ‘POWER’ LED
will light up (Fig. 6) but no audible or visual fault will be generated. In this state, the batteries will not
be under charge.
Figure 6 – Over voltage
Note: The green ‘POWER’ LED remains lit in this state to indicate that the panel is operable
but visually the amber LED will appear brighter.
Rechargeable back up battery
The rechargeable battery pack provides an emergency power supply in the event that primary power is lost
or isolated. The system will be in fault when it is being powered by the back up battery but will still be
operable for a minimum 96 hours (typical) provided that the battery is fully charged (2 hour charge time).
Figure 7 – Back up battery
When the battery voltage drops below 11 volts the Amber Power LED will flash continuously until the voltage
drops below 9.8 volts. At which time the system will shutdown to prevent over discharge or damage to the
battery.

Topic 2: Installation
Depending on the type and size of equipment requiring protection, the MKII can be configured with multiple
actuation and detection devices.
Figure 8 – Typical fire system configuration
The MKII can be customised to suit just about any application. The settings that can be altered and the
degree to which they can be customised are detailed in the ‘Channels’ section on Page 11.
Each component of the MKII must be located and positioned according to its function.
Before installing any system component you should assess the intended location will;
•Provide access for operational and maintenance purposes.
•Provide a high degree protection from potential damage
•Be compliant with the Chubb specifications and customers requirements.
The recommended wire gauge size for all power, inputs and outputs of the MKII is as per the following table;

Control Module
The control module (Fig. 4) comprises an IP65 rated enclosure and IP69 rated Deutsch DT series
connectors and is the heart of the system. It can be installed with the factory (“default”) settings or configured
to suit a specific requirement. The modules’ pin configuration is displayed in Figure 9.
Inputs
•2 x detection circuit inputs (supervised). Suitable for linear heat detection cable or
thermal probes. The control panel can be configured for four different detection functions.
The default configuration is single circuit detection.
•1 x manual discharge input (supervised). Operation of a switch connected to this input will
initiate alarm, system discharge and equipment shutdown functions.
•Cylinder pressure switch input
•Discharge pressure switch input
Note: both pressure switch inputs are configurable for N/O or N/C operation. The default
configuration is N/C (contacts closed = normal operation, contacts open = fault/discharge).
Outputs
•Actuation output (supervised) 1A @12V DC. The actuation output is capable of operating:
oA singe 12V 12W solenoid, or
oUp to 5 x .5amp squibs.
Note: The MKII Dual system has a second actuation output with the same capability as
the first.
•Shutdown output. Selectable contacts, N/O or N/C (default N/O), latching 3 pole relay
clean contact capable of switching 2A @ 30V DC.
•Auxiliary output. Selectable N/O or N/C (default N/O), latching relay clean contact capable
of switching 2A @ 30V DC.

Configuring the module
It is recommended that any configuration changes that are required to the default settings be carried out
before installation. It is preferable to use an external power supply to make configuration changes. When a
stable primary power supply is present the ‘PRIMARY POWER OK” LED on the PCB (Fig. 10) will be lit.
Figure 10 – Primary power LED
If an external power supply is not available, the back up battery circuit can be used to make the required
configuration changes. All MKII modules are supplied from the factory with a charged battery
To activate the back up battery on the MKII module (Fig. 11), a loop (Fig. 12) must be made between
terminal 3 & 4 (Fig. 13) on the module’s power supply connector (Fig. 14).

Programming - configuration channels
If the factory default settings are acceptable, no additional programming is required to the MKII before
installation. If a new configuration is required your will need to re-program the system. It is recommended
that a stable and constant power supply be present when programming the MKII.
Using the interface
The segment display (1) may not be lit when you first
open the module cover or if the interface has been
inactive for more then 10 minutes.
Press the ‘Channel’ button (2) to activate.
The channels are ordered as listed in Table 2 & 3
and each press of the ‘Channel’ button will advance
to the next channel. You can also press and hold the
button to scroll automatically.
The current configuration of the channel is shown on
the LED indicators (3) when the channel is selected.
Figure 17 – User interface active
Programming
Step 1- Select a Channel
Press the ‘Channel’ button repetitively
(or hold) to advance through to desired
channel.
For example;
If you want to change
the shutdown
delay time from the default configuration
of 30 sec to 60 sec – stop advancing at
Channel ‘C’.
Figure 19 shows the table that lists all of
the configurations for Channel ‘C’. For a
complete list of each settings that are
available for each configuration you will
need to refer to the Configuration tables

Step 2 - Pre-programming
When the desired channel is selected,
change the dip switch positions using a
flat bladed screwdriver (Fig. 20) to mirror
the illuminated LED’s
. (On LED = On
switch.)
As some channels have
configurations for more then one
function, failure to perform this step may
result in a unde
sirable configuration
change
Note: Although the LED numbers are
linked to the corresponding numbered
switches they will not illuminate at this
stage.
Figure 20 - Dip switches
Step 3 - Program mode
Press and hold the “PROG/SAVE”
button (Fig. 21) for 3 seconds to activate
program mode.
The ‘dot’ indicator light (Fig. 22) on the
seven segment display (bottom right
corner) will begin to flash.

Step 4 - Changing a configuration
Now move the dip switches (on or off) to
match the positions in the desired row of
the configuration table.
In programming mode the LED’s will
now light up when their numbered switch
is turned on.
Following on from the example in step 1;
To change the ‘Shutdown Delay – Initial’
time from 30 seconds (default) to 60
seconds – Turn switch 1, 2 & 3 to the
ON position and switch 4 to the OFF
position.

b. Detection Mode and Auxiliary Output Mode
There are two detection circuits which can either be disabled completely or configured for;
1. Single Mode - If single circuit detection is selected, detection circuit 2 is disabled. If
multiple detectors are required to cover additional hazard areas they will need to be
wired in series
Figure 28 – Single Mode

VS-MKII Control System
Chubb Fire & Security Pty Ltd
Technical Manual
Page 18 of 63
2. Single & Isolate Mode – As per single mode but detection circuit 2 is enabled to allow
interface with an external switch that would be fitted for the purpose of isolating the MKII,
thus preventing electrical actuation during routine maintenance on the equipment.
Figure 29 – Single and Isolate mode
3. Dual Detection, single zone - In this mode, one detector circuit operating will cause a fire
alarm condition. Once in alarm, operation of the second detection circuit will initiate a
system discharge. This configuration reduces the risk of an accidental discharge and
equipment shutdown but should only be used when both detections circuits are located
in the same hazard area.
Figure 30 – Dual detection, single zone
4. Single Detection, two zones - In this mode, either detector circuit operating will cause a
fire alarm and initiate a system discharge.
Figure 31 – Single detection, two zones
Upon any detector operation, the display panel and buzzer will initiate an audible and visual fire
alarm consisting of illumination and latching of the Alarm LED and sounding of the buzzer once per
second.

C. Shutdown delays
Shutdown Delay – Initial
The default setting for the shutdown delay (the time it takes for the shutdown relay to operate after a
fire alarm) is 30 secs. Shutdown delay times can be chosen in 5 second intervals from 0 to 20
seconds, 10 second intervals from 20 to 40 seconds, 20 second intervals from 40 to 180
seconds and 30 second intervals from 180 to 240 seconds.
Shutdown Delay – Extension
The default setting for the shutdown time delay extension is 30 secs.
Shutdown extension times can be chosen in 5 second intervals from 0 to 20 seconds, 10 second
intervals from 20 to 40 seconds, 20 second intervals from 40 to 180 seconds and 30 second
intervals from 180 to 240 seconds.
The MKII control system is configured by default to allow only one time delay extension period to the
equipment shutdown. The number of engine shutdown delay cycles can be increased using
Channel L. The initial and extended delay periods can be independently set to different values. Both
delay periods should be kept as short as safely possible.
