SFS1-CPU Main Board Installation Sheet
Description
The SFS1-CPU Main Board processes all information from
modules installed in the same cabinet and from other control
panels in the life safety network. In addition, the SFS1-CPU
Main Board provides:
•
Identification of hardware and software faults, and ground
fault detection
•
Common alarm, common trouble, and common
supervisory relay outputs
•
One signaling line circuit (SLC), with the option of adding a
3-SDC1 card to provide a second SLC
•
An Ethernet connection for panel programming and
diagnostics (requires an optional SFS1-ETH1 card)
•
Connections for the network data and digital audio risers
(requires an optional 3X-NET8, 3-NET, 3X-FIB8, or
3X-FIB card)
•
Connections for R
-Series remote annunciators
•
Connections for communication with FireWorks
workstations
•
Connections for communication with a building
management system (requires an optional field server
bridge)
Installation
WARNING:
Electrocution hazard. To avoid personal injury or
death from electrocution, remove all sources of power and
allow stored energy to discharge before installing or removing
equipment.
Cautions
•
Circuit boards are sensitive to electrostatic discharge
(ESD). To avoid damage, follow ESD handling
procedures.
•
If removing the SFS1-CPU main board, first pull out the
four plungers securing it to the electronics chassis. Failure
to do so may result in damage to the main board.
To install the SFS1-CPU:
1. Install any cards required as described on the installation
sheets received with the cards.
2.
Connect the data ribbon cable (P/N 250189
-01) to J17 on
the back of the SFS1-CPU and the power supply cable
(P/N 250187
-
01) to J15. See
Figure 1.
3. Feed the cables between the chassis rails. See Figure 2.
4
. Connect the loose end of the data ribbon cable to J1 on
the PS10-
4B power supply and the power
supply cable
to J2.
5
. Align the SFS1-CPU plungers and any option card with
the plunger holes and card guides on the electronics
chassis as shown in Figure 2.
6.
Gently push the SFS1
-CPU card until it is firmly seated,
and then press the four plungers into place.
Wiring
Connect the SFS1-CPU field wiring as shown in Figure 3
through Figure 13. See Figure 1 and Table 1 for the
connectors and terminals on the SFS1-CPU.
Notes
•
General wiring notes:
•
All field wiring connections to the SFS1-CPU are
made using plug-in terminal blocks.
•
Maintain
0.25 in. (6 mm) separation between power
-
limited and nonpower-limited wiring at all times. Keep
nonpower-limited wiring in the shaded area shown in
Figure 13. Secure the wiring to the cabinet using
nylon cable ties.
•
Wiring is power-limited.
•
Network data and digital audio wiring notes:
•
Network data and digital audio wiring is supervised
and unshielded.
