15.9.2.1 Outputs types and output ports

Each output type can be assigned to one of the 6 physical output ports on the SPC

controller or to an output on one of the connected expanders. Output types that are

not assigned to physical outputs act as indicators of events on the system and may

be logged and/or reported to remote central stations if required.

The output ports on the expanders are all single pole relay type outputs (NO, COM,

NC); therefore, output devices may need external power sources to activate if they

are wired to expander outputs.

The activation of a particular output type depends on the zone type (see page [➙

284]) or alert condition that triggered the activation. If multiple areas are defined on

the system then the outputs on the SPC are grouped into system outputs and area

outputs; the system outputs are activated to indicate a system wide event (e.g.

mains fault) whereas the area outputs indicate events detected in one or more of

the defined areas on the system. Each area has its own set of area outputs; if the

area is a common area for other areas, then its outputs will indicate the state of all

the areas it is common for, including its own state. For example, if Area 1 is

common for Area 2 and 3, and Area 2 Ext. Bell is active, then the Area 1 Ext Bell

output is also active.

Some output types can only indicate system wide events (no specific area

events). Please refer to the table below for further information.

Output Type

Description

External Bell

This output type is used to activate the system external bell and is active when any

Area External Bell is active. By default, this output is assigned to the first output on the

controller board (EXT+, EXT-).

Note: An external bell output is automatically activated whenever a zone programmed

as an Alarm zone triggers an alarm in Fullset or Partset modes.

External Bell Strobe

This output type is used to activate the strobe on the system external bell and is active

when any area strobe is active. By default, this output is assigned to the strobe relay

output (Output 3) on the Controller board (NO, COM, NC).

Note: An external bell strobe output is automatically activated whenever a zone

programmed as an alarm zone triggers an alarm in Fullset or Partset modes. The

external bell strobe activates on a ’Fail to Set’ condition if the strobe on the ’Fail to Set’

option is checked in system options.

Internal Bell

This output type is used to activate the internal bell and is active when any area

Internal Bell is active. By default, this output is assigned to the second output on the

controller board (INT+, INT-).

Note: An internal bell output is automatically activated whenever a zone programmed

as an Alarm zone type triggers an alarm in Fullset or Partset modes. The internal Bell

activates on a ’Fail to Set’ condition if the Bell on the ’Fail to Set’ option is checked in

system options.

Alarm

This output turns on following alarm zone activation on the system or from any area

defined on the system.

Alarm Confirmed

This output turns on when an alarm has been confirmed. An alarm is confirmed when 2

independent zones on the system (or within the same Area) activate within a set time

period).
