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 [➙ 269]. 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.
This is the SPC communications bus used to network expanders
together on the system. See page [➙ 40]. SPC4000 only has 1 X-BUS
interface.
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.
The SPC controller provides a 1 A, single-pole, changeover relay that
can be used to drive the strobe output on the external bell.
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 Hol d 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 [➙ 54].
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 [➙ 51].
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.
Serial port 2 terminal
block
Serial port 2 terminal block (TX, RX, GND) 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 that no devices are connected to this serial port.
Ethernet connectivity
LEDs
The 2 Ethernet LEDs indicate the status of the Ethernet connection. The
left LED indicates data activity on the Ethernet port; the right LED
indicates the Ethernet link is active.
The Ethernet interface provides for the connection of a PC to the
controller for the purposes of programming the system.
This USB interface is used to access browser programming or a terminal
program.
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.
This RS232 serial port may be used to interface to an X10 protocol
device.
A primary (left slot) and back-up (right slot) module can be connected to
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.
This on-board front tamper (switch & switch) provides the cabinet tamper
protection.
