4-Input / Output Interface
The four input/output interface unit can be configured
to provide any combination of up to four inputs and/or
outputs. An output of either normally open or
normally closed relay contacts can be used to control
a resistive or inductive load. An input can be
programmed as a fire, fault, supervisory or
confirmation input with configurable delay to filter
noise or spurious signals during switch transition.
Additionally the confirmation input can be configured
with an additional longer delay before an input is
accepted.
1-Output & 1/4-Input Interface
This interface unit can be used to control a resistive
or inductive load via a set of single pole change over
contacts. In addition there are 4 inputs for use to
monitor external equipment.
Confirmation Input / Output functionality
An input and an output of an interface unit can be
paired to operate in a confirmation mode. External
equipment can send an acknowledgement upon
receiving a signal from the interface unit, this is called
'confirmation input'. External equipment can also
receive an acknowledgement from the Interface unit
upon sending it a signal, this is called 'confirmation
output'.
Confirmation input
The confirmation input can be either a normally open
switch input or a normally closed switch input from
external equipment, such as a damper control unit.
A confirmation input generates a fault if a change of
state is not seen within the predefined period of a
specific output.
Unused Channels
Any unused channels must be configured as 'unused'
during the configuration stage using the
commissioning tool.
Loop wiring
The Mains switching interface unit must be wired to
the device loop circuit of the fire system. The loop
circuit can accommodate a number of Mains
switching interface units and on loop power up each
device is given a soft address.
