FLOW DETECTION Specifies whether Flow Detection is in use. When set to
ON, the “Released” condition will not be established if
flow is not detected during the release period. The
display will also show “No flow Detected”.

Press √ to learn
The actuator output type must be learnt.
Press the button to proceed and the panel will analyse
the circuit to determine the type of actuating device(s).
It will also analyse the circuit impedance. No other
adjustments are necessary.
3.3.3.2 Cause and Effects Programming
The display presents a menu of parameter options along with their current settings.

Release Active When:-
TWO Z1&Z2 : √ .
TWO Z1&Z3 : X
TWO Z2&Z3 : X
ALL Z1&Z2&Z3 : --
IMMEDIATE Z1 : --
IMMEDIATE Z2 : --
IMMEDIATE Z3 : --
Some options are mutually exclusive. Depending on the
options selected, some options are inhibited and cannot be
adjusted – the current setting is shown as ‘- -‘.
The settings only apply to the AFD inputs. A Manual
Trigger input will immediately generate the activated
condition.
If all three ‘Two Zone’ parameters are enabled then the
activated condition is established when any two of the
three zones are in the fire condition.
Use the ÏÐ buttons to highlight the required option and then press the button to select it. The
table below details each available option.

When set to NO, the RELEASED condition is established at the instance the actuator output is turned on.
NOTE: Irrespective of the setting for this parameter, if a valid signal is received on the flow input circuit then a RELEASED
condition will be established.
