– The communication bus between
Controller and Routers and
between Controller and Remote

communication between these
elements is not possible. Also,
when the processor is damaged or
fails the system will not function
properly. In that event the fault will
be clearly indicated on the
Controller, Routers (if installed)
and Remote Controls (if Installed)
Also an audible signal is generated
at the Controller and Remote
Control. The installer must ensure
that during downtime for repair or
maintenance the safety of the
occupants is ensured.
Responsibility of the installer to
verify that proper procedures are in
place. If the processor is defective,
no calls can be made. If the
communication bus between
routers, or between controller and
remote control is broken, no call
can be made beyond the point of
the broken connection.
c The system shall be capable of broadcasting
within 10 s after primary or secondary power
is applied.
Compliant. It is recommended that the

is programmed to have the highest
priority.
d Except during the condition described in
4.1c), the system shall be capable of
broadcasting a first attention-drawing signal
within 3 s of being placed in an emergency
mode by the operator, or automatically on
receipt of a signal from a fire or other
detection system. In the latter case, the
period of 3 s includes the reaction time of
the detection system from the time the
emergency is first detected, to commanding
the alarm broadcast.
Compliant. The installer is required to
ensure that the Fire detection system
does not have latency beyond 2s to
ensure that the entire installation reacts
within 3s.
Note: Reaction time of the Voice Alarm
System reacts within 1 second.
