Elcom Hands-free in-house telephone

This product consists of a hands-free indoor station for wall mounting, made of high-quality ABS plastic and featuring a loudspeaker. It includes four function keys: talk on/off, door opener, light, and call cancel. The operation can be adjusted for full or half duplex. There are 12 harmonic call tones available, with 6 gong tones that can be selected. Call tones can be freely assigned to distinguish between door, storey, or internal calls.

The device offers electronic adjustment of ringing tone volume, a ringing tone canceler with a control display, and an optical status display. It supports call waiting when a connection is active, call barring, and automatic call disconnection after 3 minutes. Up to three indoor stations can operate in parallel. Storey call forwarding is facilitated via the i2BUS to the parallel indoor stations. The Drehfix function allows for one-man commissioning by addressing with a rotary coding switch.
