The AM492-series Vandal Resistant Apartment Entrance Panel is a modular series for use with TekTone® apartment intercom stations. Panels are equipped with a Mylar, voicefrequency response speaker protected by a louvered panel and perforated aluminum material. The speaker panel can accommodate up to 18 push buttons. For more than 18 apartments, the AM492 is used with the AM490/12 or AM490/22 push button add-on panel.
Pressing the button corresponding to the desired name and apartment number causes a buzzing at the apartment station. The resident may then converse with the caller. Controlled entry is permitted by push button operation of the electric door release. AM492 panels with 0–10 buttons are available with postal option.
