The Alpha Communications® AM492 series Tek-Guard™ Vandal-Resistant entrance panel is a modular series for use with simplex type, loudspeaker suite stations.

Panels are equipped with a mylar, voice-frequency response speaker protected by a louvered speaker grille. The speaker panel can accommodate up to 18 push buttons. The aluminum push button actuators may be engraved with up to four letter/digit combinations (at extra cost). For more than 18 suites the AM492 is used in conjunction with the AM490 series push button panel modules (without a speaker).

Pressing the button corresponding to the desired name and suite number causes a signal 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 (add suffix 'P' to the model number).
