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.

Mounting and Wiring

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)

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.

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
