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).
Page 4
The unit is supplied already fitted with a BT Redcare enabled SIM card and is pre-configured to give GPRS connectivity. 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.
(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.

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 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 4 connector on the block. The outputs are transistor driven and use an internal 10K resistor to give the high state.

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.
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 10
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.

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.

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).

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.
Page 16
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.
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.
Page 18
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.
Page 21
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.
Page 22
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.
Page 23
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. ...

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.
Page 25
At any time the configuration mode can be exited, without saving changes, by holding down M for 5 seconds. Note. The account on the BT Redcare servers must match the interface combination of the unit. Either IP/GPRS for secure IP, or GPRS/PSTN for secure 2/3.
Page 26
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.
Page 27
Comms Fail output mode (F8) Output 1 on the unit is a comms fail output. This is a transistor driven output that switches low. The unit has an integral 10K pull up resistor to pull the output high. See Outputs section for further information.

Web console To access the web console a PC needs to be connected to the Ethernet port. A cross over Ethernet cable maybe required. Check for the green LED to the left of the Ethernet connector, blinking with the passing of data. This ensures the correct connectivity. Configure the PC to have a static IP address within the range 192.168.222.xxx.

The web console “quick start” page in Fig. 17 is shown populated with the factory defaults. Clicking on the “Save Config” button, at the bottom of the screen, sends the configuration to the unit and then restarts the unit. Definition of quick start settings Account Information.

Galaxy mode. When the galaxy mode checkbox is ticked then GPOP1 & 2 can directly drive a zone input on a Honeywell Galaxy panel by connecting the GPOP output through a 1K resistor to the galaxy zone input. See Fig 18. Fig 18 - GPOP set to Galaxy mode on web console.

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.

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.
