f) PA-Live Audio Sources
The model NEO4500LE has audio inputs for use in PA-LIVE mode. This inputs will be
activated through the configuration software and are dedicated to those cases where it is
preferred not to control the audio input from the NEO system. In this case, audio inputs go
directly to the amplifier outputs. The priority level can be configured. When the system is
in emergency mode, it will take control of the outputs.
For example, in a theater or a stadium, it is possible to connect the mixing console to the
inputs and use the NEO-4500LE for live pro-audio installations, with the advantage that in
case of evacuation, it will always prioritize the emergency inputs of NEO. In this sense, the
voice reinforcement system can also be used for evacuation.
2.4.8 System Integration Ports
a)
General Purpose Inputs/Outputs (GPIO)
The equipment has 14 GPIO ports for system events, programmable though the
configuration software. GPIO ports work with TTL-level logic signals (0 - 5V DC).
Figure 29 - GPIO Ports
The connection is made using 7 female euroblock type connectors with 3 contacts and
pitch 3.81 mm (supplied with the unit). The wire size range for each pole of this
connector is: 0.14
→
1.5 mm2 (30
→
14 AWG).

b)
Port for Advanced Integration with the CIE
The equipment has a supervised serial communications port, RS-485,
for connection to the central fire detection system / Control and
Indicating Equipment (CIE). To select a compatible system that will
connect the equipment you should use the configuration software.
The connection is via a female euroblock type connector of 3
contacts and pitch 3.81 mm (supplied with the unit). The wire size
range for each pole of this connector is: 0.14
