All setups
Data type: Uint8
A digital impulse triggers the fire mode operation with stop on all alarms as option [2] Trip, all alarms/test in parameter 24-09 Fire Mode
Alarms Handling. This test impulse signal can only activate 1 test time period and the normal fire mode operation takes over as soon as
the test time ends, or it stops the test period if the fire mode signal disappears. Only "normal high impulse" signals can trigger the test
timer and test information is included in the LCP and status word, as fire mode output "not operating as expected" is activated.
24-43 Fire Mode Signal Operation
Default value: –
Setup: 1 setup
Data type: Uint8
Ensure that the correct input selections and connections are in place as it is not possible to operation the LCP while fire mode is
activated.
If signal handling is set to inverse, a low [196] FM active and a low [197] FM was active indicate that the drive is off or power
cycling, which can be used to activate a redundant system.
Select how fire mode input and output signals are handled. Before changing this parameter, disable parameter 24-00 Fire Mode
Function.
