To reset the programming settings to default and reboot the controller:
– Hold down the button until you are asked if a factory reset is desired.
– Select YES to reset to factory defaults.
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.

Earth
connection
terminal
This terminal is not required and should not be connected.
6
X-BUS
interface
This is the SPC communications bus used to network expanders together on the
system. See
Terminals 1B and 1A must be connected to SPCP355.300 I/O Expander 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 12V open collector resistive outputs with a 300mA
current rating.
The OP4 load must be connected to the SPCP355.300 Smart PSU.
8
Relay
output
The SPC controller provides a 1A, single-pole, changeover relay that can be used to drive
the strobe output on the external bell.
9
Bell Hold-
Off (BHO)
and Tamper
Return (TR)
The BHO (Bell Hold Off) and TR (Tamper Return) (and EXT output) are used to connect
an external bell to the controller. See
10
Internal Bell
(negative)
The INT- terminal is used to connect to internal devices such as an internal sounder. The
power for the internal sounder must be connected to the SPCP355.300 Smart PSU.
11
External
Bell
(negative)
The Ext- terminal is used to connect to external devices such as an external bell. The
power for the external sounder must be connected to the SPCP355.300 Smart PSU.

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
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.
