INTRODUCTION

Product Description

Figure 1 - Secure Mk3 unit

The BT Redcare secure Mk3 unit is a Dual path alarm signalling unit for transmitting alarm
signals from a customer’s alarm panel, via the BT Redcare ESP network to an Alarm receiving
Centre (ARC). The unit can be used in the GPRS/PSTN configuration for “BT Redcare secure
2/3” service, or the IP/GPRS configuration for “BT Redcare Secure IP” service.

The unit communicates via the BT Redcare Enterprise Services Network (ESP) and a valid TA
account must exist for the unit to communicate. The TA account will have been populated with
the serial number of the unit.

The unit has 16 general purpose alarm inputs, and 3 outputs, making it suitable for connection
to most common alarm panels.

MOUNTING AND WIRING

Removal of cover

The top cover can be removed by inserting a screwdriver blade into the 6 slots at the top of the
unit, and levering the plastic outwards to release the 6 clips.

Regular access to the inside of the unit should not be required, although occasional access
may be required to access the SIM card, or to add a daughter board for additional facilities.
(i.e. dial capture board).

The unit supports all BT Redcare enabled SIM types. (BT Redcare O2 / BT Redcare BT
mobile / BT Redcare Roaming). The SIM type is auto detected by the unit without need for any
configuration change.

Mounting

The unit should be mounted inside the alarm panel, or inside a separate powered housing,
using the sticky mounting pads supplied.

The back of the unit also supports DIN rail mounting for housings that support this type.

The supplied aerial should be mounted on top of the outside of the housing by removing the
adhesive backing.

Page 4

Connection terminals

The Screw terminal blocks for the alarm inputs, and other connections, are removable making
it easier to change out a unit should the need arise.

All terminal blocks are of the “Degson electronics” type, and suitable for use with a standard

3mm blade terminal screwdriver.

Figure 3 - Degson terminal Connectors

When fitting the terminal blocks, please ensure that they are fully seated to the circuit board.

Power connections

Power to the unit is via 2 screw terminals at the bottom left, with positive being nearest the
edge of the board. The supply voltage range is 9V to 30V. The unit is designed to be
connected to the Auxiliary power output on an associated alarm panel, or separate powered
enclosure. Ensure the power source is sufficient as per the power requirements in the

specification section. Te account at the alarm receiving centre (ARC) should be put “on test”

before power up, as signals will be sent following initialisation

Alarm inputs

The unit has 16 alarm inputs which are presented on screw terminals along the bottom of the
unit. These are labelled as Pin 1-16. The first 8 alarm inputs also each have 0V and a ‘pos

bus’ terminal associated with them. By default the 16 alarm inputs required a positive condition

to be presented to send an alarm. (Default = Positive applied). This can be changed using the
PL, P1 or P2 button menu. See later section on configuration.

The alarm input terminal blocks are 4 way with inputs 1 – 8 on the last 2 connectors of the first
4 blocks, and inputs 9 – 16 are consecutive on the last 2 blocks.

Pos Bus

There are 4 pos bus terminals presented on the first 4 alarm blocks. These terminals are
tracked together on the unit and can be used to provide more connection + points by wiring
the first to the positive supply as per fig 4. The Pos Bus is also tracked to the expansion
module sockets (J202 and J604) and may be further utilised with some future expansion
modules.

Figure 4 - Utilising the Pos bus rail

Outputs

Three transistor outputs are provided on screw terminals at the top of the unit, and these have
an associated 0V terminal on the 4th connector on the block. The outputs are transistor driven
and use an internal 10K resistor to give the high state.

By default, output 1 is comms Fail, output 2 is CTRL, and output 3 is RPS. See the further
sections on outputs for a full explanation.

Serial data connections

RS232 TX & RX is also provided and RS485 A & B on another 4 way terminal block.

These ports allow serial alarm panel connection. See Panel Upload Download section.

PSTN connection

The telephone line connection is made to a 2 way terminal block at the top right of the unit.

The PSTN connection is not polarity sensitive. Connect the terminals to a standard PSTN line
that supports DTMF outgoing access.

July 2013 © British Telecommunications plc 2013

Page 6

The PSTN connection is required for “BT Redcare secure 2” and “BT Redcare secure 3”
service.

If the telephone line carries ADSL (broadband) then an additional ADSL micro filter will
normally be required. Suitable hardwired ADSL micro filters are available from the BT Redcare
web shop. www.BT Redcare.bt.com

The unit is supplied pre-configured with the necessary 0800 telephone numbers to connect to
the BT Redcare network.

An additional 2 way block marked “Panel A B” allows for the PSTN line to be diverted out

through an onboard bypass relay for carrying out PSTN dial in panel UDL.

Note the “Panel A B” connection purely presents the PSTN out via the units bypass relay. This
is not a dial Capture connection.

Ethernet connection

The Ethernet port needs to be connected to a suitable Ethernet network for “BT Redcare
secure IP” service using CAT5 cable. For most IP installations, a standard Ethernet patch

cable can be used. The Ethernet port can also be used to connect to a local PC for advanced
unit configuration. This connection may require an Ethernet Crossover cable as the unit does
not auto detect cable type.

Aerial connection

Connect the supplied aerial to the MMCX connector on the top left of the unit. The aerial
should be placed in a position that receives the best wireless coverage for the GPRS network
being used. Carry out a survey with a signal strength tester to establish the best location.

If necessary, a selection of higher gain extension aerials can be purchased from the BT
Redcare web shop at www.btinstallershop.com

PROGRAMMING

Programming Port

The programming port is used for upgrading the software on the unit using a USBNav
programming dongle, or analysing the units de-bugs information using a USB to TTL serial
cable (3V3).

See section on serial de-bug for further information.

Unit initialisation

At power up the unit will display its current software level on the display.

Figure 5

In the above example the display cycles 60 -41- 60 -11 -06 indicating that the software level is
K60P41A60P11 Release Candidate 06

The unit will then immediately attempt to connect to the BT Redcare platforms over the
configured paths. The unit will typically complete path establishment in the following times
from power up.

Page 8

The unit sends a “Unit Restarted” event (pin 984,1) over the first available path, followed by a
“Unit restarted” restore (pin 984,3) within 2 seconds. The unit also sends the state of all 16

pins and the state of the PSTN voltage alarm and low Battery alarm. Sending these alarm
states at start up help to ensure that the ARC alarm handling software reflects the true state of
all pin alarms after start up.

Status displays

The unit clearly displays its status on the 2 X 7 segment LEDs. An additional green LED is
provided at the side of the Ethernet connector to indicate packet flow on Ethernet.

In its normal working state, the unit will cycle displaying the signal strength (SS), pins in alarm
state (AL) and Grade of service (Gd) in 1s steps. i.e. It will show “SS” followed by the received
wireless signal strength from 0 – 31. The display may also occasionally display 99 as the

signal strength if the unit’s Cinterion wireless modem is unable to determine the current signal

strength. For reliable GPRS operation the signal strength should be at least SS-12, or higher.

After the signal strength is displayed for 1s, the unit will then show “AL” followed by any alarm

inputs 1-16 that are currently in the alarm state. If no pins are in the alarm state, then it will
show AL followed by 00. The unit may also show Lb (low battery) if the supply voltage is below
the supply threshold, and t1 or t2 if test modes t1 or t2 are active.

After the alarms status is displayed for 1s, the unit will then show “Gd” followed by the Grade

of service i.e. Gd-04 for Secure IP, or Gd-02 for Secure 2 etc. The Grade of service can only
be determined by the unit while in contact with the ESP. The unit will not show Gd until at least
one path is commissioned and the polling rates can be retrieved from the ESP. The unit may
show Gd followed by - - if the polling parameters cannot be determined.

Path Status

The state of the communication paths is indicated by the LED dots on the displays.

Figure 9 - Path status dots

July 2013 © British Telecommunications plc 2013

Page 11

The dot on the left display indicates the status of the wireline path, and the dot on the right is
the status of the wireless path.

The dot will be off when the communication path is unavailable. It will flash when the unit has
obtained a suitable IP address during establishment, and will be steady on when the path has
been fully commissioned.

The dots will also briefly blink off when data is being passed over that link. i.e. each time the
unit is polled then a brief blink is seen on the associated path dot. Also alarm transmission will
be seen as a brief blink on the associated path dot.

When fully commissioned over both paths, then both dots should be on.

The meanings of the dots are somewhat similar to the path status LEDS on previous secure
units, and they also share some commonality with the dots on a BT Redcare 5G STU. The

mnemonic “Left Landline” helps as a reminder as per 5G STU.

Additionally, when representing the PSTN path, the left dot will blink to indicate “low PSTN
voltage” and rapid flash to indicate PSTN communication to the platform is in progress.

Of the 16 alarm pin inputs, all behave as general purposes inputs with the following
exceptions.

Pin 4 has the RPS output associated with it. (See output 3 RPS)

Pin 11 acts as an ATS input as per the requirements of the BSIA form 175 document. This
applies only when output 1 is set to BSIA mode (F8 =1).

Pin 13 acts as an AC fail input and therefore has a default 7 minute delay before a pin 13
alarm is transmitted. It also has a 7 minute delay before a reset is sent. On presenting an
alarm condition to pin 13, the units display will show the alarm immediately (AL 13) but 7
minutes of constant alarm condition needs to elapse before transmission. Similarly, a pin 13
restore will immediately remove the AL 13 from the display, but 7 minutes of constant restore
condition needs to elapse before transmission of the pin 13 restore.

The 7 minute time delay can be configured through the web console by typing a new value 0-7

in the “Mains Fail delay” field. If the “Mains Fail delay” is set to 0, then pin 13 can be used as a

general purpose alarm input. (Subject to ARC acceptance).

Output 1

Output 1 acts as the communications fail output. The mode of operation can be selected
through the F8 button menu. (see config section)

By default output 1 acts as a BSIA form 175 output. (F8=1). This allows the alarm panel to
interrogate path faults as single path or dual path. That is, the output is normally low when
both paths are OK.

By default the output will switch high, following either path fail, once the relevant ‘debounce’
time has expired. (Defaults 2 minutes for IP, 15 minutes for GPRS and 15 minutes for PSTN)

If ATS input (pin 11) is toggled during the fail period, i.e. (panel interrogation) then output 1 will
either pulse low to indicate a single path failure, or remain high to indicate a dual path failure.

The unit also supports inverted mode BSIA175 operation by learning pin 11 to be positive
removed.

Output 1 and 2 also support galaxy mode. See galaxy mode section.

July 2013 © British Telecommunications plc 2013

Page 13

Figure 11 - wiring to an alarm panel that supports single / dual path identification

Output 2

Output 2 normally acts as a control output. This can be switched on and off by issuing the
relevant telemetry command from the ARC.

Telemetry request ID=0, Data=01 sets GPOP2 to low. ID=1, Data=01 sets GPOP2 high.

Output 2 can also become a secondary path fail output if F8 is set to 4.
In this case output 1 behaves as a primary path fail output, and output 2 as a secondary path
fail output.

Output 1 and 2 also support galaxy mode. See galaxy mode section.

July 2013 © British Telecommunications plc 2013

Page 14

Figure 12 - connecting a relay module to CTRL output 2. Note that the outputs sink
current when low

Output 3

Output 3 acts as a “Return Path Signalling” (RPS) output.

The output is normally low, but will rise high when input pin 4 is triggered. It will return low
when an acknowledge signal is returned from the BT Redcare server (ESP). The output has a
minimum operation time of 1s. When the acknowledgement is received in less than 1 second
after pin 4 is triggered then the output will remain high for 1s.

This output can be inverted through the web console if required.

CONFIRGURATION

The unit is supplied pre- configured with factory default values. For most installations no
changes to the configuration are required.

The unit can either be configured by using the on-board Mode (M) and Set (S) buttons, or
through a PC connected directly to the Ethernet port by surfing to the web console.

Only limited configuration is available through the button method, and more advanced
configuration requires web console access. Most installations will require no configuration
changes, the unit being supplied ready for installation at default.

A minority of sites may require minimal configuration changes at installation, and most of these
will be achievable through the button config. i.e.

 Change the PSTN predial string.
 Change the interface combination from GPRS/PSTN to IP/GPRS
 Change the IP mode from dynamic to static, and allocate a static IP

address/subnet/and gateway address.

 Change the comms fail output type etc.

Button configuration

The button configuration mode is entered by holding down the Mode (M) button for 3s.

The unit will then display the first menu item PL. (Pin Learn)

The configuration mode can be exited at any time, without saving changes, by holding down
the M button for 5s.

If a user gets lost within the menus then repeatedly pressing M will return to the main menu
and eventually reach the ?? save option.

When in the main menu, each press of the mode button will step to the next menu item down,
and eventually return to the top of the menu. The full main menu options are shown in Fig. 13.

Pressing the set (S) button on any menu item will enter the sub-menu and allow the function to
be changed. Depending on the menu item will depend on the structure of the sub-menu.

Typically, many menu items simply have the option to switch on or off. Where 0=Off and
1=On. In such menu items, the Set (S) button toggles the On / Off state, and the Mode (M)
button returns to the main menu.

Some menu items have more options. i.e. F8 has 4 options to set the comms fault output type.
On such menus, the Set (S) button enters the sub menu, the set (S) button increments through
the 4 options with each press, then the mode (M) button returns to the main menu.

Some more complex menu items use the mode button to also step through additional levels in
the sub menu. i.e. P1 sets the polarity of pins 1 to 8. The set button enters the P1 submenu.

July 2013 © British Telecommunications plc 2013

Page 16

The S button toggles the polarity of pin 1, the M button increments to pin 2, where the S button
can be used again to toggle the state. Each press of M will increment the pin, up to the last pin
8 and then return to the main menu.

A similar process is used on the menu items that allow IP addresses to be input. Set button (S)
enters the sub menu. Set button (S) then increments the first digit with each press. Mode
button (M) increments to the next digit, where button S can again be used to set this value.
The M button will increment through all digits 1-12 in the IP address.

Some special characters are used on the displays. These are detailed in fig. 14.

At any time the configuration mode can be exited, without saving changes, by holding down M
for 5 seconds.

Pin learn

The polarity of pins can be learnt by the installer selecting the PL option on the button menu.

Pressing Set (S) at PL will flash PL on the display to prompt “Are you sure?”

Pressing Set (S) again will cause the unit to read the state of all 16 inputs and assume the
current state is the normal (no Alarm) state.

Pr will briefly be presented on the display as the new pin polarity config is written to flash
memory. The unit will then restart.

There is no requirement to “save the changes” after PL.

Example – to learn the pin polarity:-

 Access the button config menu by holding M for 3 seconds. PL is displayed
 Press S – the display now shows PL flashing for “Are you sure?”.
 Press S – the display shows Pr as the new polarities are stored.
 The unit restarts.

At any time the configuration mode can be exited by holding down M for 5 seconds

Test mode 1 (t1) Web console access

To allow access to the web console, the t1 menu must be entered and set to 1. Access to the
web console is then allowed. There is no need to save the change on the unit, simply use the
Set (S) button to toggle the t1 value to 1 and then press mode (M) to return to the t1 main
menu option. The unit will now have a static IP address of 192.168.222.222 for the duration
that t1 is set to 1. This does mean that a unit configured for IP/GPRS will be unable to
communicate across the IP path while in test mode 1. A comms fail on the IP path will
therefore be signalled to ARC after the normal time out (normally 3 minutes). The GPOP1
output will also operate after the time out (normally 4 mins) indicating single path fail. This is
considered normal. The GPRS path will still function OK while in test mode 1. i.e. the unit will
respond to incoming polls over GPRs and can be manually polled from the ESPUI if required.

The PSTN path will also function OK while test mode 1 is enabled. i.e. new alarms presented
to pins during test mode 1 can be sent over GPRS, or PSTN if required. They cannot be sent
over IP.

Test mode 1 will automatically exit after 20 minutes.

Test mode 1 can manually be set back to 0 (off) at any time by the installer.

Test mode 1 will revert to off if the unit is restarted. i.e. after clicking on the “save” button on

the web console.

See section on web console for further information.

At any time the configuration mode can be exited by holding down M for 5 seconds.

Page 20

Test mode 2 (t2) Force alarms over secondary path.

For test purposes an installer can set the unit to send all alarms over the secondary path. This
is achieved by accessing the t2 menu and setting the value to 1. There is no need to save the
change on the unit, simply use the Set (S) button to toggle the t2 value to 1 and then press
mode (M) to return to the t2 main menu option. Test mode 2 is now active and all new alarms
will be sent over PSTN on a PSTN/GPRS configured unit, or GPRS on an IP/GPRS configured
unit.

When test mode 2 is on, then incoming polls on the disabled path will still be responded to by
the unit. Therefore the platform will not normally report a communications failure because of
test mode 2 being active.

Test mode 2 will automatically exit after 20 minutes.

Test mode 2 can manually be set back to 0 (off) at any time by the installer.

At any time the configuration mode can be exited by holding down M for 5 seconds.

Example – to set test mode 2 on. All alarms sent over secondary path:-

 Access the button config menu by holding M for 3 seconds.
 Repeatedly Press M until t2 is displayed.
 Press S – the display now shows the current t2 state. Where =0 is Off, and =1 is On.
 Press S to toggle the mode off and on. Where =0 is Off, and =1 is On.
 Press M to return to the t2 menu. (The test mode is now active)

At any time the configuration mode can be exited by holding down M for 5 seconds.

Pin Polarity (P1 & P2)

The polarity of the pins can manually be configured by the installer. This is additional to the pin
learn function described earlier. (P1 = pins 1 to 8 and P2 = pins 9 to 16)

By accessing the config menu by holding (M) for 3 seconds, and then stepping with (M) to the
P1 menu option, pressing set will enter the pin 1-8 sub menu.

Polarity of pin 1 is displayed, and can be toggled with the (S) button.

Further presses of (M) will step through all pins 1-8 showing their current polarity and allowing
each to be toggled to pos applied or pos removed with the (S) button. Once all 8 pins are set
as desired then (M) will return to the main menu (P1). Note that any changes are not saved
until the ?? option is accessed and (S) is pressed twice.

Pins 9 – 16 can be checked or changed in a similar way be accessing the P2 menu.

Note that the dot on the left display is on to distinguish pins 9-16 from 1-8. i.e. P2 menu has
the left dot lit, while the P1 menu does not.

The unit will reboot after the changes are saved at the ?? menu.

Example – to configure pin 4 to be positive removed:-

 Access the button config menu by holding M for 3 seconds.
 Repeatedly Press M until P1 is displayed.
 Press S – the display now shows pin 1 and its current polarity.
 Repeatedly press M until pin 4 is shown with its current polarity.
 Repeatedly press S until the required pin 4 polarity is shown.
 Repeatedly press M to scroll through the rest of the pins and then to the ?? (save

changes question marks)

 Press S and the ?? will flash to prompt “Are you sure?”
 Press S and the unit will briefly display Pr (program) as the changes are written to

flash. The unit will then restart.

At any time the configuration mode can be exited, without saving changes, by holding down M
for 5 seconds.

Ethernet mode - Static / DHCP (F1).

The function 1 (F1) button menu allows the unit to be changed between dynamic (DHCP
client) or Static mode.

When F1 is set to 0 (default) then the Ethernet port will attempt to obtain an IP address from a
DHCP server on the LAN.

When F1 is set to 1 then the Ethernet port can be configured with a static address by using the
F2 / F3 and F4 menu functions.

Example - To change the Ethernet mode:

 Access the button config menu by holding M for 3 seconds.
 Repeatedly Press M until F1 is displayed.
 Press Set – the display now shows the current mode. i.e. =0 for DHCP, or =1 for Static.
 Press S to toggle the value to the required setting.
 Press M to return to the F1 main menu.
 Repeatedly press M to scroll to the ?? (save changes question marks)
 Press S and the ?? will flash to prompt “Are you sure?”
 Press S and the unit will briefly display Pr (program) as the changes are written to

flash. The unit will then restart.

At any time the configuration mode can be exited, without saving changes, by holding down M
for 5 seconds.

Setting a static IP Address, Netmask and Gateway Address (F2 F3 and F4)

It the secure unit is to be connected to a LAN that requires the unit to have a static IP address
(i.e. no DHCP server on the LAN) then this can be configured as follows.

 IP Address = 192.168.1. 56
 Subnet mask = 255.255.255.0
 Gateway = 192.168.1.254

Note that IP addresses are made up of 12 digits in 4 batches of 3, separated by dots. When
the addresses are entered through the buttons they must be put in as 12 digit numbers, with
zeros used to the left of each batch where necessary to pad out the addresses. i.e.

 IP Address = 192168001056
 Subnet mask = 255255255000
 Gateway = 192168001254

The digit number (1-12) will be shown on the left display, and its value on the right display.

for 5 seconds.

Tunnel port (F5)

When used in IP mode, the unit will attempt to establish a connection to the BT Redcare
servers by signalling on IP Port 443. For most LANs this will function correctly, but on some
advanced LAN configurations the network manager may not allow outgoing access on port
443 but 10443 may have outgoing access. Where this is the case then the unit can be
configured to use the alternative port 10443. The BT Redcare servers are set to accept both
ports and so no changes are required other than on the unit’s configuration.

PSTN Pre-dial string (F7)

The unit is supplied with the necessary telephone numbers to dial the BT Redcare servers
when in PSTN mode.

At some sites it may be necessary to add a predial number to the telephone number. i.e. a
digit 9 to gain an outside line on a business line.

A predial string of up to 8 digits can be configured through the F7 menu.

Example. Changing the unit to dial 9 with a 1 second pause.

 Access the button config menu by holding M for 3 seconds.
 Repeatedly Press M until F7 is displayed.
 Press S to enter the predial sub menu. (the display shows the first predial digit 1 x)
 Repeatedly press S to step the first predial digit to 9.
 Press M to move to the second predial digit. (the display shows the 2nd predial digit 2

x)

 Repeatedly press S to step the 2nd predial digit to P for a 1 second pause.
 Press M to move to the 3rd predial digit. (the display shows the 3rd predial digit 3 x)
 Set the 3rd predial digit to blank. (this indicates the end of the predial string).
 Press M to return to the F7 main menu.
 Repeatedly press M to scroll to the ?? (save changes question marks)
 Press S and the ?? will flash to prompt “Are you sure?”
 Press S and the unit will briefly display Pr (program) as the changes are written to

Tip. The predial special characters for * and # are shown on fig. 14.

Tip. P will give a 1 second pause.

Tip. The ‘close square bracket’ symbol tells the unit not to dial the leading zero on the

telephone number. This is useful for using the unit outside of the UK, where an international
dialling code may be required as the predial string.

i.e. A predial string of 0044] may be used from some countries where 00 is the international
access code.

Web console status and log screen

Figure 19 - Web Console “Status and log” screen

July 2013 © British Telecommunications plc 2013

Page 34

The status and log screen shows the current system status, and access to the unit’s event

history.

The Event log history is extensive and will go back further than the last unit re-start. (i.e. the
event history is stored in flash memory and not cleared by loss of power). The event log will
store a minimum of 1025 events.

Events that are generated while the time on the unit is not set, i.e. after the unit has been
powered up but before the unit has communicated with the ESP to obtain the correct time, are
time stamped with the pseudo time and date in the year 2000 as per Fig. 18.

Note that events logged while the unit’s time has been synchronised will use Greenwich Mean
Time (GMT).

When a PSTN call is attempted and fails to establish, a “Fail to communicate” event is logged
in this local log. For further debugging there is a “Device number” associated. i.e. Device 0/2

means the unit failed to dial the second telephone number.

Other typical messages that may appear in the log.

Telephone line restore. Device 0 PSTN has successfully dialled up after a fail.

Fail to communicate. Device 0/1 PSTN call to Telephone number 1 failed

Fail to communicate. Device 0/2 PSTN call to telephone number 2 failed

Panel upload Download.

Remote access to the alarm panel can be achieved using the BT Redcare UDL facility.
Contact your BT Redcare representative for details of accessing the BT Redcare UDL servers.

Remote Service Suite

Roaming SIMs

The unit will auto detect the sim type that is present in the unit. Most units are supplied pre
fitted with a Roaming Sim. Where a Roaming Sim is fitted then the unit will switch between
GPRS networks to maintain connectivity should connectivity be lost on the current network.

The unit will search the available networks for a signal stronger than the “Roaming CSQ limit”

at unit start up. (Default 19)

Should the unit lose connectivity with the BT Redcare platforms, or lose registration with the
current base station, then the unit will roam onto the next available GPRS network.

Dial capture board

The dial capture board is a module that can be added to a BT Redcare Secure Mk3 unit to

enable interfacing with an alarm panel’s digital communicator. The alarm panel can then send

SIA, CID or Fast Format messages through the Secure Mk3 unit to the Alarm receiving centre.
The dial capture board can also be used for upload download UDL allowing remote access

with some types of alarm panel.

July 2013 © British Telecommunications plc 2013

Fitting the dial capture board.

 Power down the Secure Mk3 unit.
 Use an ESP strap to provide electrostatic protection to the circuit boards.
 Remove the plastic cover by releasing the 6 clips on the rear of the Secure Mk3 unit

with a small screwdriver.

 Remove the Printed circuit board PCB from the plastic base.
 Identify the 20 way connector J202 and the 6 way connector J801 on the secure Mk3

unit.

 Line up the 20 pins of J100 and the 6 pins of J200 on the dial capture board.
 Ensure that the dial capture board is correctly aligned and press fully into the

connectors.

 Insert the screw through the hole in the rear of the PCB and gently tighten to hold the

dial capture board in place. (Do not over tighten)

 Re-assemble the Secure unit and replace the plastic cover.

The secure unit will auto detect the dial capture board at power up. For most installations no
additional configuration is required.

Connect the alarm panel’s digital communicator line connections to the terminals marked

Panel A, Panel B on the secure Mk3 unit. The unit is not polarity conscious.

July 2013 © British Telecommunications plc 2013

Configure the alarm panel digital communicator to dial 29 and use the last 4 digits of the TAID
as the account number.

The dial capture board will auto detect the panel protocol as events are sent from the alarm
panel. SIA, CID or FF.

Note some early Secure Mk3 units may have taller connectors J202 and J801 preventing
securing with the screw and fitting of the plastic cover.

Secure IP (Grade 4 only) specification notes

IP Protocol: TCP

Port: 443 or 10443

Data Usage / Requirements

Secure IP Grade 4 polling is every 30 seconds. A poll and response results in 288 total bytes
transferred (incl IP headers). A small number of alarms will also typically be generated per
day and these result in 296 bytes transferred. Overall this generates approximately 800 K
Bytes per day, per site.

Traffic Direction

Secure IP establishes an outgoing TCP connection from your network to the BT Redcare
Enterprise Services Platform (ESP). Once this outgoing TCP connection has been
established, traffic over that connection is 2 way.

Additional Protocols

Only TCP is required from your network.

Port Forwarding

No ports need to be forwarded in the incoming direction. The outgoing TCP connection
connects to port 443 or 10443 on the BT Redcare ESP network, so you would need to allow
outgoing access to port 443 or 10443 if you block that by default.

NAT: Not required

GPRS Requirements

You do not need to route GPRS traffic. The GPRS connection from the Secure IP
communicator through to the BT Redcare ESP and on to the ARC is entirely independent of
your network.

DHCP and Static Addressing

The Secure IP communicators can be configured as either DHCP clients or with specific static
IP addresses on your internal network as you prefer.
