6.11.20 Transmitter blocking

In the event of a transmitter failure, the 'transmitter lock' function can be used to remove a channel from the list of active
channels. The control panel with a blocked transmitter does not communicate and deactivates all signals (ALARMS) of the
channel. Pressing a channel button locks the corresponding channel. Press again to unlock the channel. Blocked channels are
indicated by a dark color and a red mark.
Figure 60 Transmitter blocking
Tip: blocked channels are automatically unblocked after the control panel is reset.

6.11.21 Service mode

The control panel service mode is used to block the output relays. It is used for the needs of service performed 'on the fly'
when manipulation with the transmitter and the like could lead to the shutdown of the monitored technology. Pressing the
output button blocks the corresponding output. Press again to unlock the output. Blocked outputs are indicated by a dark
color and a red mark.
