IDA4SU is an optional unit that will provide the SINAPS-M and SINAPS-XM systems with the following additional features :
1) Fault back microphone : in case of failure of one or more IDA 4M/S modules, the IDA4SUs will automatically connect one PSS microphone directly to all amplifiers inputs, allowing the user of the system to make an all call announcement.

2) a+b zone wiring on same amplifier : when two speaker circuits are used in a zone, they can be connected to the same amplifier. The IDA4SU unit will take care of the separate line surveillance according EN 60849 and BS 5839 part 8 regulations. If one of the speaker circuit is shorted, then it will be disconnected without influencing the other circuit of the corresponding zone.
The front panel LEDs will provide following information :
1) Separate zone circuit status (Yellow if zone circuit is Faulty)
2) Fault back microphone function (Yellow if bypass mode active)
3) Power (Green if power supply is OK)
The IDA4SU setup is supported by the SINAPS PC configuration software and does not require any additional programming.
