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
Wireless/PSTN configuration for Redcare Secure 2/3 or Fire service, or the IP/Wireless configuration for Redcare Secure IP
or Fire IP service. The unit can also be ordered as a single path wireless only device Redcare Secure Solo.
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.
The unit is supplied already fitted with a BT Redcare enabled SIM card and is pre-configured to give GPRS or 3G
connectivity. The Secure MK3 has a unique algorithm which ensures the best network available is selected.
The unit is supplied pre-configured to connect to the BT Redcare network servers over PSTN 0800 dial up numbers or
through IP tunnelled networking.

Removal of Cover
The top cover can be removed by gently releasing each of the 6 clips on the base of the unit with a screwdriver blade.
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.
For fire alarm panels the enclosure must meet the requirements of EN 54-21 7.3 (eg. IP30
or above) and the supplied sticker should be applied to the outside of the housing (fig 2).
Enclosure requirements for the Secure unit are the same as for the fire alarm panel itself and
must meet EN 54-2. The enclosure must restrict access to installer level 3. The enclosure
must provide the facility to indicate the state of the fault and acknowledge outputs on
the Secure unit.
For security installations the enclosure must meet or exceed the protection requirements
of the particular security grade for the whole installation as per EN 50131-1
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.
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. For use with intruder alarm panels the power supply must meet
the requirements of EN 50131-6. For use with Fire alarm panels the power supply must meet the requirements of EN
54-4 and the Secure unit must be mounted in the same enclosure as the power supply from which it derives its power.
Ensure the power source is sufficient to power all devices connected. See the power requirements in the specification
section. The 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 require 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. Example pin configuration as follows
Fig 4 - Alarm input allocations. (Functions must be agreed with ARC)
Figure 3 - Degson terminal Connectors
When fitting the terminal blocks, please ensure that they are fully seated to the
circuit board.

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 5 - Utilising the Pos bus rail

Page 9
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.
For fire alarm installations the indication of ‘acknowledgement of fire alarm’ and ‘SPT fault’ messages must be
provided by the fire panel into which the SPT is mounted.
System fault indications which are notified by the line fault output ( GPOP1 & RL1) must be latched by the fire panel as
required by EN 54-21.
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 using standard telephone cable CW1308.
The PSTN connection is required for Secure 2 , Secure 3 and Secure Fire 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. https://www.btinstallershop.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 Panel to be connected using dial capture mode if a dial
capture module is fitted within the secure unit.
Ethernet connection
The Ethernet port needs to be connected to a suitable Ethernet network for Secure IP and Secure Fire 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. Carry out a survey with a signal strength tester to establish the best location.
If necessary, a selection of extension aerials can be purchased from the BT Redcare web shop at
https://www.btinstallershop.com

Programming Port
The programming port is used for upgrading the software on the unit using a USBNav programming dongle, or analysing
the units de-bug information using a USB to TTL serial cable (3V3).
Unit Initialisation
At power up the unit will display its current software level on the display.
Figure 6 – Software level displayed at power up.
In the above example the display cycles 60 -46- 60 -54 -03 indicating that the software level is K60P46A60P54
Release Candidate 03
Secure Fire IP and Secure Fire require K60P46 A60P54 release Candidate 3 or later for LPS1277 V3.0 and CPR
Secure IP , Secure 3 and Secure Solo require K60P46A60P54 or later for LPS1277 V3.0
See information on page 48 and 54 for third party certification
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.
Figure 7 – time to commission paths after unit 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.

Page 12
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 wireless modem is unable to determine the current signal
strength. For reliable Wireless 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 <10.9V, restore >12.1V) 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 10 – Path status dots

Page 14
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 1 must be used for Fire alarm when ACK NAK outputs are used for Fire panels. (Secure Fire IP and Secure Fire only)
Secure Fire IP and Secure Fire provide an acknowledge and not acknowledged indication via use of its General purpose
outputs and the attached relay board for alarm pin 1
Pin 4 has the RPS output associated with it. (See output 3 RPS (N/A for Secure Fire products)
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). N/A for (Secure Fire products).
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).
Pins 1 – 8 can be set up for End of Line and Dual End of Line interconnection monitoring see descriptions on pages
14-16
Default Outputs for Secure IP, Secure 3, Secure 2 and Solo
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
Wireless 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 16
Figure 12 – 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.
Output 2 is configured to be a Fire Nak output on Secure Fire products. When configured in this way GPOP2 will activate
after a pin 1 alarm is sent and no ack is received for 80s

Page 17
Figure 13 – connecting a standard 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.
Output 3 is configured to be a Fire ACK output for Secure Fire products. When configured in this way, output 1 will
activate when an acknowledgment to a pin 1 alarm is received. It will de-activate when the pin 1 resets.
Secure relay module
A Secure Relay Module is available from redcare to provide relay contacts for the Secure Mk3 unit outputs and is fitted as
standard on Secure Fire IP and Secure Fire. See accessories on page 47 for further details.

Page 18
Deafult Outputs for Secure Fire IP and Secure Fire
To ensure that the secure Mk3 unit can inform the fire alarm panel of status as per the requirements of EN 54, the
outputs are configured as follows.
Output 1
GPOP 1 Standard line fault 1 ( F8 = 2) Will operate when either signalling path fails. The output switches low. Relay RL1
on relay board (can also be used as a general fault output see note* below)
Output 2
GPOP 2 Fire (GPI1) Nak. will operate after a pin 1 alarm is sent and no acknowledgement from the Alarm Receiving Centre
(ARC) is received for 80s. RL2 on relay board
Output 3
GPOP 3 Fire (GPI1) Ack will operate when an acknowledgment to a pin 1alarm is received from the ARC. It will return to
normal when pin 1 is reset. RL3 on relay board
*A secure relay module is used to simplify connections of the outputs to fire panels. Where the fire panel has just one
fault input the contacts of GPOP1 and 2 can be wired in series to trigger this. i.e. a comms fault or Nak will trigger the
fault input on the fire panel. GPOP1 should be set so that in the normal state the relay is energised. This ensures that, in
the unlikely event of a total failure of the secure unit, the fire panel will still detect a state change on its fault input.
Interconnection Monitoring
If the enclosure housing the secure unit is not next to, or close coupled to, the fire panel i.e. right next to the fire panel
enclosure or perhaps a very short (<25mm/1”) section of cable conduit coupling the enclosures together then there is a
requirement in EN54-21 to detect open or short circuits on the interconnection wiring between the fire panel and the
Secure unit as well as an indication back to the fire panel of an issue.
The power connections need to meet EN54-21 7.5.2 when the Secure unit is fitted in an enclosure remote from the Fire
control panel.
To enable the interconnection monitoring you will need to program the unit via the web console
(see pages 16 and 34)

Alarm event and restore,
Wire cut and wire shorted.
The seven segment displays will show C1 through C8 (following the AL symbol) to indicate the wire cut condition for any
of PINs 1-8, which are presently in the wire cut state.
The seven segment displays will show S1 through S8 (following the AL symbol) to indicate the wire shorted condition for
any of PINs 1-8, which are presently in the wire shorted state.
For Example
Relay 1 (RL1) will operate on a wire cut or wire short alarm
Alarms will also be sent through to the Alarm Receiving Centre for each of these conditions
