terminals 2B and 2A, respectively
Terminals 2A and 2B must be connected to terminals 2A and 2B,
respectively, of the next expander on the X-BUS.
7 On-board outputs Outputs OP4, OP5, and OP6 are 12 V open collector resistive outputs
with a 300 mA current rating.
The OP4 load must be connected to the SPCP355.300 Smart PSU.
8 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.
9 Bell Hold-Off (BHO) The BHO (Bell Hold Off) and TR (Tamper Return) (and EXT output) are
and Tamper Return used to connect an external bell to the controller. See page [➙ 87].
(TR)
10 Internal Bell
The INT- terminal is used to connect to internal devices such as an
(negative) internal sounder. The power for the internal sounder must be connected
to the SPCP355.300 Smart PSU.
11 External Bell The Ext- terminal is used to connect to external devices such as an
(negative) external bell. The power for the external sounder must be connected to
the SPCP355.300 Smart PSU.
12 Do not use. Do not use.
13 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].
14 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.
15 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.
16 Ethernet connectivity The 2 Ethernet LEDs indicate the status of the Ethernet connection. The
LEDs left LED indicates data activity on the Ethernet port; the right LED
indicates the Ethernet link is active.
17 Ethernet interface
The Ethernet interface provides for the connection of a PC to the
controller for the purposes of programming the system.
18 USB interface This USB interface is used to access browser programming or a terminal
program.
19 Serial port 2 This RS232 serial port may be used to interface to 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 no
devices are connected to this serial port.
20 Serial port 1 This RS232 serial port may be used to interface to an X10 protocol
device.
21 Optional plug-in A primary (left slot) and back-up (right slot) module can be connected to
modules the controller. These modules can be GSM or PSTN modems offering
increased communication functionality. The back-up modem should not
be connected if serial port 2 interface is connected to an external modem
or other device.
22 Real-time clock Battery for real-time clock (RTC).
