Audio Amplifiers; 60/120 Watt Amplifier Module - Panasonic Firetracker FT1020G3 CIE Technical And Programming Manual

The OWS is supplied with a wide range of high efficiency class-D audio amplifiers: 60, 120
or 250 Watts. A basic OWS system fitted in FT1020G3 supports the following standard
Features:

Digital voice messages for alert and T3 (or AS2220 evacuation tone)

Supervised trigger Input (short/open circuit fault)

Supervised dual Strobe 24V

Supervised 100V speaker line output (open/short circuit fault).

Fault Relay output (changeover contacts)

Fault indicators for strobe output, trigger input and speaker circuit on OWS main

Standard 60W OWS can be powered from the FT1020G3 power supply (battery backup
must be upgraded). When larger OWS is required e.g. 120W or 250W, separate power
supply and power supply supervision must be used. Larger amplifiers may require larger
cabinets depending on the space available.

OWS faults are hardwired via this common fault relay to input I0 - 13 in FT1020G3 to display OWS fault on the LCD. In NZ
convention, I0 cannot be used, it has to be I1 - !3.
