    Section 950-719-100 August 22, 1997 Revision 03 IRING CCESS All wiring to the COTS is done on the backplane. To access the backplane, remove the clear Plexiglas™ cover. LARM EADS Audible and visual alarm leads from the CO alarm panel to the COTS must be provided. Run the Alarm leads down the side of the COTS mounting frame.

  • Page 24: Power Connections

    Revision 03 August 22, 1997 Section 950-719-100 • TB1 FGND Connection The seven-position power-terminal strip termination point, TB1, is on the shelf backplane. A minimum of 12 AWG should be used for this connection. Using minimum 12 AWG wire, attach a spade lug connector to terminate the ground wire on the FGND terminal of TB1.

  • Page 25: Redundant-Shelf Powering

    Section 950-719-100 August 22, 1997 Revision 03 Redundant-Shelf Powering Each circuit card in the COTS receives power from two -48 V dc sources. If one -48 V dc source is lost, the other -48 V dc source provides power to the shelf circuit cards. Each -48 V dc source is fused at 20 amps. A four-position jumper is in place on the TB1 block (Figure 6).

  • Page 26: Split-Shelf Powering

    Revision 03 August 22, 1997 Section 950-719-100 Split-Shelf Powering One half of the shelf is powered from one -48 V dc source, the other half is powered from another -48 V dc source. Common equipment circuit cards are powered from both sources. If one power supply should fail, one- half of the shelf maintains power.

  • Page 27: Single-Source Powering

    Section 950-719-100 August 22, 1997 Revision 03 Single-Source Powering The entire shelf is powered from a single source of -48 V dc power fused at 20 amps. A four-position jumper is in place on the TB1 block. This jumper shorts all of the 48 VDC inputs together to prevent an alarm situation when only one input feed wire is connected.

  • Page 28: Audible And Visual Alarm Connections

    Revision 03 August 22, 1997 Section 950-719-100 Audible and Visual Alarm Connections Use a wire-wrap tool to terminate the alarm leads from the external alarm equipment on the alarm relay wire-wrap field. See Figure 9 for the location of the alarm relay wire-wrap field. Table 21 shows the layout of the wire-wrap pins on the COTS backplane.
