Chapter 3: The circuit boards of the central unit
Loop processor board SPK-2
The loop processor boad SPK-2 exists in three different models. Model 1 and
model 2 differs only in the exterior of the front panel, whereas Model 3 has an own
block diagram.
General
The loop processor board SPK-2 controls and supervises two detector loops with
analogue and addressable detectors. The detectors are constantly polled in order to
detect faults or changes in alarm status. Detector-initiated alarms are also
recognised and verified. The events are reported to the LPK-2 and proper hardware
signals are then activated.

Block diagram Model 3
SPK-2 Model 3 can be split into three functions: Power supply, loop and processor
with memory. The power supply provides the board with loop power and power for
the logic and the processors. The loop part contains electronics for two loops and
handles power supply for the loop and sending/transmitting of IDA and NOSE
messages. The processor controls the loops and communicates with the LPK via the
RS485 channel of the back plane.
The whole board is galvanically isolated from the CS3000 rack.

DC/DC converter
Power is taken from the back plane and converted via a galvanically isolated
DC/DC converter into 35V. The 35V is used to power feed the loops and is also
converted to 5V for the logic. The voltage feed is fused.
Control logic
Signals in the back plane for fuse fault, voltage fault and prim-alarm. All signals
are galvanically isolated between SPK-2 and the back plane.
LEDs
Indicating status of the system. Some LEDs are active only in service mode.
CPU, memory and watchdog
The CPU controls and supervises the communication on both loops and also
communicates with the LPK. The memory contains program code with initial
values for the loop units and also gives status information. The watchdog
supervises the CPU and activates a reset signal to the CPU in case of malfunction.
Address switch
An 8-pole DIP-switch deciding the physical address of the board.
RS485 LPK communication
One asyncronous channel of the processor is used for communication with the
LPK. These signals are adapted to the RS485 levels and are galvanically separated
from the back plane.
Service plug
RS232 channel used for service, debugging and downloading of code.
Earth fault measurement
Measuring positive and negative earth faults. Since the board is galvanically
separated from the rest of the system, the measurement is a local indication of earth
faults from the loops. Earth fault is not measured when the board is used for
connection of GSK.
Loop : EMC protection
Protecting the electronics from various EMC disturbances.
Loop: Short circuit protection
Contains two parts, one part automatically disconnecting the loop power when the
current consumption exceeds allowed limit and one part which is used to control
the power feed to the primary and/or secondary side of the loop.
Loop: Line power
Feeding the loop with correct DC voltage and current and adapting the loop to the
signalling used on IDA and NOSE loops.
Loop: Current measurement
Measuring the DC current which is fed to the loop.
Loop: Signal filter
Separating and filtering out IDA/NOSE communication from the DC supply
voltage on the loop.
Loop: Line modem
Sending and receiving IDA/NOSE communication. Communication with the
processor via serial channel.

General
The alarm processor board LPK-2 controls and supervises the external alarm
devices. The board also controls external functions such as fans, fire doors and
release of fire extinguishing agents through relay outputs. The LPK-2 also
monitors all communication within its own central with all loop processor
boards. The LPK-2 that is situated in the main central unit also monitors all
communication on the system loop with control units and with external
computers, printers, etc.
The alarm processor board exists in two different models, which differ only in
the exterior of the front panel. Model 2 has an additional connector for
downloading data from a computer.

1. DC/DC converter
The DC/DC circuit converts the battery voltage of the back plane to 5 VDC,
which is supplied to all logical circuits on the board.
2. CPU/Memory/Watchdog
This is the main block of the LPK-board. The CPU uses the memory circuits for
executing the programme code. There is also a non-erasable memory containing
the system configuration and the external controls. The watchdog supervises the
processor and checks that there are no hang-ups in the programme execution.
3. LED indications
One green LED indicates that the board is power supplied. If the watchdog is
activated (possible fault in the board), a yellow LED is lit, indicating system
fault. Furthermore there are two LEDs (one yellow and one red) indicating fault
and alarm in the central unit. Finally there are two green LEDs that are used for
service purposes.
4. Address switch
With the DIP switch the 8-bit address of the LPK is set.
5. Real time clock
The real time clock is keeping track of the time in the system. The clock has
built-in registers for seconds, minutes, hours, days, week-day, month and year
