Intercom - TE905A Master
General Information

A fully modular telephone entry intercom system for 1 to 1,000 apartments (suites). Available with No-Phone-Line option. Can be supplied with/without privacy handset.
The TE905A series Tek-Entry IIIў telephone entry intercom is a modular style entry panel, and can be used with 1 to 1,000 remote apartment telephone locations. Modular alphabetical directory modules make finding the tenant\’s 4-digit code very easy, even in larger buildings. By entering a simple 4 digit code, the system calls the correct phone number, to allow access. The called party\’s phone number remains secret. Programming and re-programming are push button simple, and are done right at the keypad. Directory strips can easily be inserted into the model #AM190D (60-name capacity) directory modules using optional engraved plastic directory strips (model #TDS) and fill-in directory blanks (model #TDS-B). Flush TE905A panels require an OF190 series frame, with the OH190 series flush housing. Surface panels require an OF190S series surface frame only, and do not require a back box.
