Cat 5 STP cable must be used for the connections.
The Emergency input has
Emergency Surveillance (critical path)
and
Activation Contacts
Surveillance
:
Emergency Surveillance (critical path)
: The device connected to the emergency input must
generate a high frequency signal (17720 Hz, 18000 Hz, 19250 Hz or 20000 Hz). The system performs
a constant check of the high frequency signal, generating an alarm in the event of short circuit,
interruption of continuity or disconnection of this input. The alarm generated is sent through the IP
network towards the control PC or the equipment units prepared to receive these alarms
(DVA-102ETH, FC-600ETH, DC-600ETH). The emergency surveillance function must be configured by
means of the P.A. Manager software (see section 6.7).
Activation
Contacts
Surveillance
: If the connections
shown in Figure 5 are made, the
system monitors the priority
contact and the two contacts for
activation
of
pre-recorded
messages from the emergency
input. In the event of short circuit
or disconnection, an alarm is
generated.
