Direct Replacement: For TekTone IR203E
IR-203E is a popular 3wire version of the IR-204E. IR-203E can be used for easy upgrades from obsolete bell/buzzer systems, to modern voice intercom systems, when existing wiring is adequate.
IR-203E can be mounted to a single gang gem box, or surface mounted directly to the finished wall using wall plugs. Additional functions include multi-entrance operation with the PK502B, AC or DC door operation selectable by terminal connection with selectable delayed action door release set at the dip switch, post office door lock release and a tone signal to call remote stations. A steady or warble tone can be used to identify calling from the main entrance panel and a call button located at the suite entrance. Braille legends, in addition to English language and icon symbols make this station easy to operate by all.
