Society Intercom
TI500 Intercom System links every flat, the main gate, the clubhouse and the office on one system. Six cabinet sizes take you from 32 to 250 extensions, with key telephones for the security desk and Talking Caller ID on every call.
One Intercom for the Whole Society
32 to 250 extensions · 2 key phones

When sixteen phones are not enough.
An apartment complex or campus needs more than a simple intercom. TI500 is built around four jobs, and it works entirely inside your premises: no exchange lines, no call charges.
Card-based cabinets
Each cabinet holds plug-in extension cards. Start with the flats occupied today and add cards as towers fill up, with the same features and numbering throughout.
Talking Caller ID
The system speaks the calling extension's number, and voice prompts read back the last five missed, received and dialled calls.
A console for security
Key telephones at the gate show busy extensions at a glance. Flat door lock release, multiple paging and emergency reporting are built in.
Protected and local
Over-voltage and surge current protection for long cable runs between blocks, in a metal cabinet. Designed, developed and manufactured in India.
Six cabinet sizes
The number in each model name is the number of card slots. Bars show the maximum phones per cabinet (extensions plus key telephones).
Cabinets are supplied with the extension cards you need now. Empty slots take more cards later, up to the maximum shown.
