7.7 Digital Inputs

Two digital input circuits are provided for connection to
ancillary equipment, if required. Each circuit can be
configured to provide one of the following input actions:
a. Class change (default)
b. Alert
c. Evacuate
d. Delay Mode (default)
e. Reset
f. Fire transmission confirmed return signal
g. Fault transmission failed return signal.
Class Change: When a class change digital input is
activated, all outputs configured as sounders will be
activated until the input condition is removed.
Alert: When an alert digital input is activated, all outputs
configured as sounders and the internal buzzer start pulsing.
The sounders and internal buzzer remain pulsing until the
digital input is deactivated. Alert operation will override class
change and fault conditions, but not the alarm condition.
Note: If the sounder output is configured as type 'pulsed'
then an alert input will cause the sounder outputs
and internal buzzer to turn on with a steady tone.
Evacuate: When an evacuate digital input is activated, a
general evacuate is initiated, i.e. all the bells activate,
until the input condition is removed.
Note: If the sounder output is configured as type 'pulsed'
then an evacuate input will cause the sounder
outputs and internal buzzer to pulse.
Delay Mode: This allows external control of delays to
outputs. It can be used to delay activation of outputs
during the day and so this use is commonly known as
Day Mode. When this input is active, delays can still be
cancelled using the 'Delays On/Off' button.
Reset: This digital input can be used to return the panel
to normal operation after the occurrence of an event,
such as an alarm or fault. Faults are latching and a reset
cannot return the panel to normal until the condition
causing the fault has been remedied.
Fire Transmission confirmed return signal: This type of
digital input provides the ability to confirm the activation
of the Fire Routing Output.
Fault Transmission failed return signal: This type of digital
input provides the ability to route Fault Routing Output
faults back to the panel. It is assumed that the external
equipment will provide the necessary fault monitoring of
the routing output and provide feedback to the panel.
