9.3.7 LED Connection
The Protector base connector has an LED output intended for
connection of external equipment like LED indicators and Fire
Protection Equipment (FPE). See the illustration below.
The LED output activates when the alarm output is active.
9.3.8 Branch-offs
If necessary, a branch-off can be connected to a detection loop if the
existing cable layout requires this, but this is not recommended, as
redundancy is lost and safety is reduced.
Limitations
There must not be more than one branch-off per detector. Multiple
branch-offs in a single detector will lead to improper loop raise and
addressing of the detectors.
Limitations
For safety reasons, the number of protectors on each branch-off
must be kept to a minimum, as the protectors on a branch-off will
not operate in case of a break or short-circuit on the branch-off. With
reference to EN54, the absolute maximum number of protectors on a
branch-off (or an open loop) is 32.
