Main Functions
1. Amplified Calling: When powered by DC24V, the HSC series voice-activated telephones can provide amplified calling with a volume increase of at least 20dB. In case of power failure, the telephone automatically switches to voice-activated calling.
2. Keypad Calling: The HSC series telephones are equipped with a call button. When powered by DC24V, pressing this button will ring the other telephone immediately, eliminating the need for a generator. It operates normally within a voltage range of 18-36V. A manual generator is required in case of power failure.
3. Noise Reduction Function: Cabin telephones can be equipped with noise-canceling headsets, enabling calls in noise levels up to 110dB.
4. Flashing Ringtone: The flashing ringtone is used in high-noise cabins such as aircraft cabins. All voice-activated telephones have a flashing ringtone terminal.
