1
Optional Wireless Module
NOTE: Wireless features and devices will be available with a later market package.
2
SPC Status LEDs
These 6 LEDs display the status of various system parameters as described in Section
16.4 Appendix E: SPC Controller Status LEDs.
3
AC Power Input
The mains AC input voltage is applied to this 2-pin connection via a transformer contained
in the SPC Enclosure. The earth lead from the mains supply is wired to a connection point
on the metal cabinet.
4
Reset Switch
Press this switch once to reset the SPC Controller. To reset the programming settings to
default and reboot the Controller, hold down the button for 10 seconds and release.
Note: Configuration will be lost.
5
Earth Connection Terminal
This terminal provides an earth connection point providing a common ground for the
Controller PCB with ancillary devices.
6
Auxiliary 12 V Output
The SPC Controller provides an auxiliary 12 V DC output that can be used to supply power
to Expanders and devices such as latches, bells, etc. See Section 16.5 Appendix F:
Powering Expanders from the Auxiliary Power Terminals. The maximum deliverable
current is 750 mA.
7
X-BUS Interface
This is the SPC communications bus used to network Expanders together on the system.
See Section 7.1 Wiring the X-BUS Interface. SPC4000 supports one communication
channel (1A 1B) for manually addressed Expanders only.
8
On-board Outputs
Outputs OP4, OP5, and OP6 are 12 V open collector resistive outputs that share a 400 mA
current rating with the auxiliary 12 V Output.
9
Relay Output
The SPC Controller provides a 1 A, single-pole, changeover relay that can be used to drive
the strobe output on the external bell.
10
Internal Bell / External Bell
Internal and external bell outputs (INT+, INT-, EXT+, EXT-) are resistive outputs with a 400
mA current rating. The BHO (Bell Hold Off), TR (Tamper Return), and EXT outputs are
used to connect an external bell to the Controller. The INT+ and INT- terminals are used to
connect to internal devices such as an internal sounder. See Section 7.6 Wiring an Internal
Sounder.
11
Zone Inputs
The Controller provides eight on-board zone inputs that can be monitored using a variety of
supervision configurations. These configurations can be programmed from system
programming. The default configuration is Dual End of Line (DEOL) using resistor values of
4K7. See Section 7.4 Wiring the Zone Inputs.
12
Front Tamper
This on-board front tamper (switch & switch) provides the cabinet tamper protection.
13
Tamper Terminals
The Controller provides two additional tamper input terminals that can be connected to
auxiliary tamper devices to provide increased tamper protection. These terminals should
be shorted when not in use.
14
Tamper Bypass [LK1]
The jumper setting determines the operation of the tamper. The tamper operation can be
overridden by fitting LK1. The engineer must ensure that LK1 is removed before leaving
site for the system to comply with standards.
15
USB Interface
The USB interface is used to access terminal programs.
16
Fast Programmer
Port for connecting to the Fast Programmer.
17
Serial Port 1
This RS232 serial port may be used to interface to an X10 protocol device.
18
X10/Serial Port 2
This port may be enabled for connecting to the X-10 port or it may be enabled as a
communications channel with the back-up modem module. If a back-up modem is
installed, ensure no devices are connected to this serial port.
19
Optional Plug-in Modules
A primary (left slot) and back-up (right slot) module can be connected to the SPC
Controller. These modules can be GSM or PSTN modules offering increased
communication functionality. The back-up module should not be connected if serial port 2
interface is connected to an external modem or other device.
