5.3 Switching off / Switching on
To avoid ↑ false alarms or fault messages, you can switch off parts of a ↑ 'Site'
↑ in certain situations, e.g., for the purpose of maintenance work.
When a part of a system is switched off, the 'Isolation' LED is on.
The situations in which part of a 'Site' should be switched off, depends on the
detectors used as well as on possible deceptive phenomena such as smoke, dust,
heat or vapour.
WARNING
System parts that have been switched off make it impossible to acquire and
process alarms or faults!
Fire may spread unhindered.
● Deploy staff to monitor the deactivated area.
● You must switch deactivated parts of the ↑ 'Site' back on as soon as possible.
If a deactivated 'Zone' is the only 'Zone' in a ↑ 'Section', the 'Section' is also
indicated as deactivated.
Examples of switching off/on are provided in the following chapters.
5.3.1 Switching a detector zone off / on

You will find information on temporarily isolating detector zones in chapter
'Temporary switching-off [➙ 114]'.
In which situations a detector zone should be switched off, depends on the
detectors used as well as on possible deceptive phenomena such as smoke, dust,
heat or vapour.
The fastest method for switching off or on is to enter a known address in the
'Element address' dialog window.
In the configuration, a standard button can be given the function of directly
opening the menu with the 'Element address' dialog window to select a detector
zone.
In the following exemplary operating sequence the process is shown without a
known address.
