WARNING
Before starting to install and work with this
device, please read the Safety Instructions.
When changing or installing the SPCP432/433
or PSU on the SPC system, always ensure
that the mains supply and the battery are
disconnected. Ensure that all anti-static
precautions are adhered to when handling
connectors, wires, terminals and PCBs.
Introduction to the SPCP432/433
The SPCP432/433 is a Power Supply Unit (PSU)
combined with a 2 Door Expander which can be
placed anywhere on the SPC X-BUS. The expander
monitors the PSU for over-current, failures with the
fuse, mains/AC, PSU and communications, and also
battery problems. The expander receives power and
data directly from the PSU via a connector cable
and interfaces with the SPC controller via the SPC
X-BUS.
Fig. 1 shows the expander (highlighted in grey)
mounted on the PSU.

PSU)

If the battery type selected does not match the
battery, it will cause the battery to charge either
too slowly, and not reach the 80 % capacity in
the required time, or too quickly, reducing the life
of the battery. The PSU shows a fault if the
jumper is not fitted.
9. PSU 4-pin Interface: Connects to item 12, Power
and Data Connector, with a straight through
cable.
10. PSU Outputs (output 1, output 2): Each output is
fused separately with electronic 1.25 A fuses.
WARNING:
The total load current drawn from outputs 1
and 2
combined should not exceed 1.5 A (750 mA
per output). This is to ensure that enough
power is available to charge the battery to
80 % of its normal capacity within 24 hours.
If more power is required on the system,
consider connecting an additional or higher
rated PSU.
11. Battery connectors (BAT+, BAT-): 2 A fuses.
12. PSU 4-pin Interface: Connects to item 9, Power
and Data Connector, with a straight through
cable.
13. Termination Jumper: This jumper as a default is
always fitted, however, when wiring for Star
configuration this fitting should be removed (see
section on Wiring the X-BUS interface).
14. Tamper By-Pass [J1]: The jumper setting
determines the operation of the tamper. The
tamper operation can be overridden by fitting J1.
15. Front Tamper Switch: The expander has a front
tamper switch with spring. When the lid is closed
the spring closes the switch.
16. Read LED: The LED indicates that data is
received from one of the card readers.
17. Buzzer: The buzzer is activated in order to locate
the expander (see SPC Configuration Manual).
18. Manual Address Switching: The switches allow
manual setting of the ID of each 2 door controller
on the system.
19. X-BUS status LED
The LED indicates the status of the X-BUS when
the system is in FULL ENGINEER mode is

Flashes quickly Indicates the last in line

seconds approx.) multi-drop configuration)
20. Outputs: The 2 door controller provides 2 relays
for connecting the door locks.
21. Card Reader Interface 2: Depending on the
configuration this reader is used as entry reader
for the second door or as exit reader for the first
door.
22. Card Reader Interface 1: The entry reader of the
first door is connected here.
23. Door Release Switch (DRS) Inputs: Each door
has a DRS input. If the input is activated the
corresponding door is unlocked.
24. Door Position Sensor (DPS) Inputs: Each door
has a DPS input. The input is used to determine
the status of the door (e.g. open, closed). If
desired this input can be additionally used as
intrusion zone.
25. X-BUS Interface: The communication bus is used
to connect expanders together on the SPC-series
system (see section Wiring the X-BUS interface).
26. Input Power:
0V must be connected to SPC controller 0V
(System GND). Do not use 12 V input.
27. Back tamper terminal block. (Fit a link across this
block if tamper switch is not used)
28. Back tamper switch.
See section on Back tamper switch installation.
When connecting a battery to the Power
Supply Unit, ensure that the positive and
negative leads are connected to their
respective terminals on the PSU. Ensure that
all safety precautions are adhered to when
handling connectors, wires, terminals and
PCBs.
Charging the battery via PSU
During normal operation, the PSU continuously
trickle charges the battery. If the mains power fails,
the battery supplies power to the PSU outputs until
such time as the battery output voltage drops to 10.5
V DC (see section Deep discharge protection) and
the PSU turns itself off.
Wiring the X-BUS interface
The X-BUS interface provides connection of
expanders and keypads to the SPC controller. The X-
BUS can be wired in a number of different
configurations depending on the installation
requirements.
NOTE: Maximum system cable length = number of
Expanders and keypads in the system x maximum
distance for cable type.

Fig. 2 shows the wiring of the X-BUS to an
expander/controller and a following
expander/controller in Spur Configuration. Terminals
3A/3B and 4A/4B are only used if using a branch
wiring technique. If using a Spur configuration, the
last expander is not wired back to the controller.

Please refer to SPC Configuration Manual of the

shielding, specifications and limitations.
Wiring the inputs
The expander has 4 on-board zone inputs.
Door Configuration
If the I/O for a specific door is configured as 'Door',
the inputs are used for a door position switch (DPS)
and door release switch (DRS).
They can be configured as follows with respect to
EOL:
• No End of Line (NEOL)
• Single End of Line (SEOL)
• Dual End of Line (DEOL)
The configurable zone types are:
• Alarm
• Entry/Exit
• Tech
• Unused
See Fig. 3: DPS input connection
1 Magnetic contact
See Fig. 4: DRS input connection
1 Exit switch
Please refer to SPC Configuration Manual for all
possible resistor values and combinations.
Zones/Outputs Configuration
If a I/O for a specific door is configured as
'Zones/Outputs', the inputs can be used as normal
wired zones except that their zone numbers will be
floating (not tied to the X-BUS ID, similar to wireless
zone numbers) and the outputs are used as normal.
Please refer to SPC Configuration Manual for all
possible EOL resistor values and combinations in
addition to configurable zone types.
Anti-Masking is only reported as 'Alarm' type
to ARC if area or system is set.
Wiring the outputs
The expander has 2 relays. These are single pole
changeover, rated at 30 V DC / 1 A resistive load.
If the I/O for a specific door is configured as a
'Door', the relay can be used for opening a door
lock. Otherwise it will be configured for
'Zones/Outputs' and the relay can be assigned to
any of the SPC system outputs.
Fig. 5 shows the wiring of a normally closed output
used with some types of door locks.
See Fig. 5: Wiring the door lock
X-BUS addressing
For addressing, reconfiguration, device location,
monitoring, editing of names, X-BUS communication
type, and failure timer, please refer to SPC
Configuration Manual.
Testing Battery Voltage
The PSU performs a load test on the battery by
placing a load resistor across the battery terminals
Distance
and measuring the resulting voltage, ensuring that
200 m
the battery voltage does not drop significantly under
400 m
load conditions. The battery test is carried out every
400 m
5 seconds.
400 m
Deep discharge protection
If mains power fails to the SPCP432/433, the
battery backup is switched on to provide power. A
battery can only maintain a supply for a finite
duration when mains/AC power is cut off for a
prolonged period. The battery eventually
discharges itself.
To prevent a battery discharging beyond recovery,
the PSU disconnects the battery when the battery
output voltage reaches 10.5 V DC. When the
mains/AC is restored, the battery is recharged.
