Tyco 4100U - Manual (Page 38)

2-10
The CPU, SPS, and all other modules to be mounted in the FACP cabinets must be
configured to operate correctly in the system via their DIP switch and jumper ports. This
section describes the hardware configuration for the CPU and SPS, since they will always
be used in the CPU bay.
The CPU motherboard must be jumpered as follows:
P9 determines whether the RUI SHIELD signal is connected to 24 C or Earth.
• Position 1 – 2: SHIELD to 24 C (default). Set to this position unless the system
uses a TrueAlert Power Supply.
• Position 2 – 3: SHIELD to Earth. Set to this position only if the system uses a
TrueAlert Power Supply.
Note: Some devices that connect to RUI have inherently grounded shield
terminals, in which case 24 C cannot be used. If 24 C is used, a
Negative Ground Fault will occur.
P10/P11: P10 is associated with Port 1 and P11 is associated with Port 2. P10 and P11 are
used to set the CPU motherboard up to be attached to either a network card or a RS-
232/2120 card.
• Position 1 – 2: Network card (NIC) attached to CPU motherboard (default).
• Position 2 – 3: RS-232/2120 card attached to CPU motherboard.
The master controller daughter card must be jumpered as follows:
P1 is used for engineering diagnostics (COMLAB).
• Position 1 – 2 : Download or no connection.
• Position 2 – 3 : Diagnostic mode.
P3 configures the RAM battery as ON or OFF.
• Position 1 – 2 : ON.
• Position 2 – 3 : OFF.
The SPS must be configured as follows:
SW1: Using DIP switch SW1, set the SPS device address. Use the address table in
Appendix A.
P2: If the SPS IDNet outputs are being used, you may change P2 to configure the IDNet
shield connection.
• Position 1 – 2 (bottom) : Connects the shield to 0 V (default).
• Position 2 – 3 (top) : Connects the shield to earth ground.
P3 configures relay 3 on the 4100-6033 Alarm Relay Card.
• Position 1 – 2 (top) : Removes fault monitoring on relay 3 (default).
• Position 2 – 3 (bottom) : Makes relay 3 activate when there is a fault.
P1: Earth connect jumper.
• Position 1 – 2 (rhs): Enables Earth fault monitoring. Set to this position unless the
system uses a TrueAlert Power Supply under common 0 V.
• Position 2 – 3 (lhs): Disables Earth fault monitoring. Set to this position only if the
system uses a TrueAlert Power Supply under common 0 V.
