- Page 2 (ARC). The 5G STU uses the extremely reliable BT Redcare network to convey the messages over a BT Redcare enabled BT analogue PSTN line. Even if an intruder cuts the line and jams the radio signals an alarm message will still rapidly be sent to the ARC.

Page 3: Pre-Installation Requirements
Pre-Installation Requirements Before a 5G STU installation can commence, a BT Redcare Service Order must be submitted to BT Redcare by the Alarm Receiving Centre. This ensures that the appropriate exchange connections have been made and a block terminal 92A has been provided at the customer’s premises. -
Page 4: Static-Sensitive Devices
Page 3 Static Sensitive Devices Static electricity is present in our everyday lives. A static charge is generated by friction, and whenever two dissimilar materials are separated. The imbalance of electrons causes a potential difference of many hundreds of volts. On discharge, a large current flows for a short time. -
Page 5: Training Courses
REN value of 1.0 unless otherwise marked. If the 5G STU is used with an MCD, the combined REN will be 1.5. Training Courses BT Redcare offer a free training course for installers of the BT Redcare service. For further information call General Enquiries Tel: 0800 800 628*. - Page 6 Page 5 Line Fault Output (LF) The Line Fault Output is used to indicate that the communication path has failed at the protected premises. The ‘Line Fault’ relay contacts (Normally Open, Common, Normally Closed) are available for connection on TB1. The maximum current rating of the relay contacts is 1 Amp.

Page 7: Telephone Line Selection (Lk1)
Note the LK1 link provides 600 ohm line matching for PW working and is only generally used on legacy RedDIRECT circuits or for test purposes. For normal PSTN connection LK1 is NOT required. If you have any doubts about the type of telephone line to which the STU is being connected, contact BT Redcare for advice. - Page 8 Page 7 5G STU Displays The current status of the STU is displayed on the 2 X 8 segment displays. The STU will cycle through the messages in 1 second steps. AL = This is followed by the ALarm pins that are active (in the Alarm state). 00 if no alarms are active, or the numbers of the pins outstanding, i.e.
- Page 9 Page 8 PP Pin Polarity Pressing SET at the PP menu option enters the pin polarity sub menu. At factory default all inputs are set to positive applied triggering. The input pin polarity can be changed by using the MODE button to step through pins 1 to 11 t & F, and using the SET button to toggle the input polarity for that pin.
- Page 10 Page 9 PE Pin Enable Pressing SET at the PE menu option enters the Pin Enable sub menu. At factory default the all inputs are enabled. Tip: There is generally no requirement to disable inputs, unused inputs can simply be left disconnected. Should a change be required the following procedure can be used.
- Page 11 Tip: Connection type 0 will satisfy most PSTN installations, but types 2, 3 & 4 can be useful to address some polling over speech (POS) faults caused by some phone type compatibility issues. The BT Redcare helpdesk should be consulted for further advice.
- Page 12 Type 1 will suit the majority of installations (default). Type 2 is for Earth calling PSTN lines that may be associated with large older type PABXs. Type 3 can be used where false disconnection of BT Redcare MCD is to be avoided after long duration (>20min) telephone calls.
- Page 13 Page 12 F5 Function 5 - Pin / Serial Data Enable Pressing set at the F5 menu option allows the Function 5 value to be configured. At factory default the F5 digit is set to 0. Tip: The Serial alarm input is for future use and not to be used on 5G STU at this time. All 5G STU’s should use the 0 setting only.
- Page 14 PSTN path has been successful. Additionally the dot will flutter each time a data poll is received over that path. Downing the STU The Down STU command can be issued from the ARC. For all 5G STU’s, this disables the port on the BT Redcare Scanner at the telephone exchange.
- Page 15 When the STU is installed on a telephone line that shares other analogue data products, e.g. fax machine, analogue modem or EPOS machine, then it is recommended that a BT Redcare Modem Compatibility device (MCD) is used. The MCD is a line powered plug-in device that connects in line with the modem of fax machine. The MCD ensures that the BT Redcare signalling does not interfere with the modem, and the modem signals do not interfere with the BT Redcare signalling.
