Control without confirmation

Building Technologies
Fire Safety
Configuration
The following configurations are supported in the case of control without
confirmation:
Once activated, the control remains permanently active

Once activated, the control only remains active for a certain time. How long the

contact remains active can be configured (pulse duration).
Once activated, the control remains astable (symmetrical pulse pattern of 1 s)

With line monitoring

Without line monitoring

Behavior in the event of an error

If used as a monitored output:
Fail-safe behavior when the FDnet/C-NET detector line is de-energized or in

degraded mode operation (e.g., if the processor on the control panel should
fail).
The error behavior defines the position of the contact in the event of an error:
‒ The contact remains in the same position as before the error
‒ The contact is activated in case of an error
‒ The contact is deactivated in case of an error
‒ The contact responds to the 'Degraded mode horn' signal like other
sounders on the FDnet/C-NET
If used as a sounder line:
Fail-safe behavior when the FDnet/C-NET detector line is de-energized or in

degraded mode operation (e.g., if the processor on the control panel should
fail).
The error behavior defines the position of the contact in the event of an error:
‒ The contact responds to the 'Degraded mode horn' signal like other
sounders on the FDnet/C-NET
The statuses of the outputs (active/not active) cannot be polled on the control
panel, only switched.
Control methods involving pulse patterns
Control methods involving pulse patterns reduce the service life of the relay
contacts on the input/output module. Contact wear is also dependent on the load.
Up to 300,000 switching cycles are permitted.
