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.

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.

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.

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.

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.

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.
