Plug-by outputs on an EXP-PSU
The plug by outputs on the EXP-PSU mirror those on the control unit. You cannot program
the plug-by outputs on the EXP-PSU to behave independently from those on the control
unit.
Custom Outputs
A custom output is a virtual logic gate within the control unit. It is similar to an AND gate or
OR gate in digital electronics, but exists only within the configuration of the control unit. A
custom output can have up to 10 inputs. An input is an event such as
Fire Alarm
or
Hold
Up Alarm
(see page 63).
You can use a custom output to activate a physical output by assigning the custom output
as the type of the physical output. For example, if you have set up
Custom Output 1
and
wish to use it to activate a physical output at the control unit, assign
Custom Output 1
as
the type for the physical output.
You must select a
Mode
for each custom output, which can be All(AND), or Any (OR). For
the AND mode, all inputs to the custom output must be active for the custom output to be
active. For the OR mode, any one of the inputs must be active for the custom output to be
active.
The number of custom outputs available depends on the control unit (see page 2).
Note:
An input can be the output of another custom output. However, you can select only
custom outputs of higher number as the custom output you are defining. For example, if
the control unit supports 4 custom outputs and you are defining
Custom Output 2
, it can
use only the outputs of
Custom Output 3
and
Custom Output 4
as inputs.
Example
Requirement: To activate a physical output when any of three fire doors (zones 5, 6 and
7) is open, but also shunted.
Solution: Configure a physical output as type
Custom Output 1
, and configure two custom
outputs as follows.
Custom
Output
Mode
Input
1
All(AND)
Input 1 type=Custom Output 2
Input 2 type=Zones Shunted
2
Any (OR)
Input 1 type=Zone Follow (Zone 5)
Input 2 type=Zone Follow (Zone 6)
Input 3 type=Zone Follow (Zone 7)
