Description
These 7 LEDs display the status of various system parameters as described in Controller
status LEDs on page 368.
A/C Mains Input:
The mains AC input voltage is applied to this 2-pin connection via a transformer
contained in the SPC housing. The earth lead from the mains supply is wired to a
connection point on the metal housing.
Clock Reference*:
A clock reference signal can also be applied to this 2-pin connector to maintain accurate
system time.
To reset the controller:
l
– Press this switch once.
To reset the programming settings to default and reboot the controller:
l
– 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.
This terminal is not required and should not be connected.
The SPC controller provides an auxiliary 12V DC output that can be used to supply power
to expanders and devices such as latches, bells, etc. See Powering expanders from the
auxiliary power terminals on page 369. The maximum deliverable current is 750mA.
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 Wiring the X-BUS interface on page 75. SPC4000 only has 1 X-BUS interface.
Outputs OP4, OP5, and OP6 are 12V open collector resistive outputs that share a 400mA
current rating with the auxiliary 12V output. If the outputs are not connected to the 12V of
the controller and are powered from an external power source the 0V of the power source
needs to be connected to the controller 0V and the external power source cannot exceed
12V.
The SPC controller provides a 1A, single-pole, changeover relay that can be used to drive
the strobe output on the external bell.
Internal and external bell outputs (INT+, INT-, EXT+, EXT-) are resistive outputs with a
400mA 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 Wiring an internal
sounder on page 89.
