Page 6: 3Gstu Overview
3GSTU-12V The 3GSTU-12V variant is a stand-alone unit for mounting inside an alarm panel or auxiliary cabinet. This variant requires a 12 V d.c. supply. And has 8eight pin alarm terminals. The power supply, relay outputs and alarm inputs are connected by means of hard wiring to the terminal blocks on the 3GSTU. - Page 7 Page 6 3GSTU-PLI The 3GSTU-PLI variant is a plug-in unit for mounting onto certain alarm panel motherboards. With the exception of the Return Path Signalling, all power supply, output and alarm input connections are made by two connectors that protrude through the base.

Tel: 0800 800 828 Pre-Installation Requirements Before a 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 redcare block terminal 92A has been provided at the customer’s premises. -
Page 12: Connecting The Telephone Line And Earth
Page 11 Connecting the Telephone Line and Earth The TNV circuit cover of the STU should not be removed whilst the unit is connected to the PSTN or Private Wire network. Remove the TNV circuit cover from the STU. Use two core telephone cable (type: 1/0.5 mm CW1308) that is not yet connected to the PSTN or Private Wire (PW) network. -
Page 13: Mains Fail
As stated at the beginning of the Installation section, the power supply must be totally powered down (switch off mains and disconnect the battery) before making these connections. For 3GSTU-12V units, connect a 12 V DC power supply to TB3. Connect +12V to the terminal labelled V+ and 0V to the terminal labelled 0V. -
Page 14: Alarm Inputs
Page 13 Alarm Inputs For plug-in units, connections to the alarm panel are made by the two connectors which protrude through the base. When fitting the unit, check that SK1 pins 1 to 8 and SK2 pins 9 to 16 correspond to pins 1 to 8 and 9 to 16 on the alarm panel. -
Page 15: Output Relays
Page 14 For panels which provide relay contact outputs, the common of each relay should be connected to an A+ terminal (TB2) on the STU. Either the normally open or normally closed contact should be connected to the relevant STU alarm input (TB1). -
Page 16: Line Fault Output
Private Wire (RedDIRECT) a suitable link must be fitted in the position marked LK1. An NVM chip must be configured for PW use and fitted in accordance with the procedure on page 17. If you have any doubts about the type of telephone line to which the STU is being connected, contact BT redcare for advice. -

Page 17 Installing The NVM The NVM (Non-Volatile Memory) chip is a device used by the STU to store configurable parameters. This memory is retained even when the power is completely removed. There is a socket provided (at IC2) for the fitting of a pre-programmed NVM. Suitable NVMs for use with the STU are National Semiconductor NM93C46N or Microchip Technology 93C46/P. -
