This Emergency and Information Help Point (EIHP) is a two-button intercom, providing users with a robust communication solution with AFIL capabilities.
The intercom combines the Turbine Compact hardware as designed by Zenitel, with the HLS-2C AFIL amplifier designed by Ampertronics, to provide high-quality audio in industrial noisy environments, with Telecoil (T-coil) integration for those with hearing impairment.
All features of an IP station are present, notable features including SIP registration, audio monitoring, high-quality audio and user-friendly configuration via web-interface.
