Interguard 60 W Amplifier

Item Number: 1009971000

100V Line

  • 1 output for 100 V line with a maximum of 60 W load
  • Line monitoring on loudspeaker output. The monitoring can be integrated with the AlphaCom line monitoring feature
  • Status indicators at the front shows error type:
    Line error, amplifier error, load error, overheating, GND fault and overload
  • AUX input and/or AlphaCom abcd-wire input
  • Connection to AlphaCom as a station or in parallel with a station
  • Volume control, and bass/treble control accessible in front. Volume level is adjustable
  • Volume override facility
  • Standby mode when no signals are present to preserve power
  • Set and reset keys for programming and service of the amplifier. Programmable impedance level for line monitoring, time between tests and error detection limits
  • Monitoring of amplifier and output for automatic change-over to standby amplifier
  • Each amplifier in closed housing, complies with IP20 classification (finger-proof)
  • Designed to meet IEC65/EN60950 requirements

The IG60 W is well suited for distribution of audio for information calls, background music and evacuation messages. Audio input can be from an AlphaCom exchange and/or other audio. The ab-wire input has priority over the AUX input. The AlphaCom exchange sees the amplifier as a subscriber station. Each amplifier can connect loudspeakers with a maximum load of 60W.

The amplifier performs line monitoring on the loudspeaker output at regular intervals. LEDs on the front panel of the amplifier indicates type of line error. Different monitoring parameters can be programmed and the references are stored in the EEPROM. The amplifier tracks slow variations in line impedance to avoid false errors. Load errors on the output like open load or shorted load will be reported to the AlphaCom as line fault. Missing power also generates a line fault, so the exchange can detect an unpowered amplifier. In addition a relay driver output supports change-over to a standby amplifier.
