English –Instructions
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.
When wiring the Mains Cable to the PSU, a readily accessible approved
disconnect device must be incorporated in the building installation wiring. This
must disconnect both phases at the same time. Acceptable devices are
switches, circuit breakers, or similar devices.
The disconnect device must have at least 3 mm distance between contacts.

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,
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.
See Fig. 1: SPCP432/433 (Expander mounted on PSU).
1 Mains Input Block
2 Input Transformer
3 Mains Power LED (see Appendix A: LED Status)
4 Battery Charge State LED (see Appendix A)
5 Fuse Fail LED (see Appendix A: LED Status)
6 Current Limit LED (see Appendix A: LED Status)
7 Status LED (see Appendix A: LED Status)
8 Battery Selector (see Appendix B: Link Position). 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. Connect Load (peripherals & X-Bus components) to
PSU Outputs.
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 as shown in the following table:

Flashes regularly (once every

1.5 seconds approx.)
Flashes quickly (once every 0.2 Indicates the last in line expander (excludes
seconds approx.) star and 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 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 an 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:
Description
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.
29 Back tamper by-pass [JP6]. Must be fitted for all expanders in the housing.
When connecting a battery to the PSU, 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.
Testing Battery Voltage
The PSU performs a load test on the battery by placing a load resistor across the
battery terminals and measuring the resulting voltage, ensuring that the battery
voltage does not drop significantly under load conditions. The battery test is carried
out every 5 seconds.
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.
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.

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.
