3 AC power input A/C Mains 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.
Clock Reference*:
A clock reference signal can also be applied to this 2-pin connector to
maintain accurate system time.

Warning: Defaulting the controller to factory settings deletes all
configuration files, including backups, stored on the controller. All isolates
and inhibits are also deleted. It is recommended you backup your
configuration to a PC before defaulting the controller.
Note: This feature is not available if engineer lockout is enabled.
5 Earth connection This terminal is not required and should not be connected.

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 page [➙ 333]. The maximum deliverable current is 750 mA.
Please Note: The amount of current drawn is subject to the amount of
time to be held up under battery conditions.
7 X-BUS interface This is the SPC communications bus used to network expanders
together on the system. See page [➙ 72]. SPC4000 only has 1 X-BUS
interface.
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. If the
outputs are not connected to the 12 V of the controller and are powered
from an external power source the 0 V of the power source needs to be
connected to the controller 0 V and the external power source cannot
exceed 12 V.
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 Internal and external bell outputs (INT+, INT-, EXT+, EXT-) are resistive
bell 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 page [➙ 87].
11 Zone inputs
The controller provides 8 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 page [➙ 83].
12 Tamper terminals The controller provides 2 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.
13 Serial port 2 terminal
Serial port 2 terminal block (TX, RX, GND) may be used to interface to
block an external modem or PC terminal program. Serial port 2 shares a
communications channel with the back-up modem. If a back-up modem
is installed, ensure that no devices are connected to this serial port.
14 The 2 Ethernet LEDs indicate the status of the Ethernet connection. The
left LED indicates data activity on the Ethernet port; the right LED
Ethernet connectivity
indicates the Ethernet link is active.

15 The Ethernet interface provides for the connection of a PC to the
IP
controller for the purposes of programming the system.
