The V-2904, Universal Four Door Answering System, when used with Valcom Door Plate Speakers, provides voice paging with handsfree reply to up to four doors from any telephone location. The V-2904 initiates ring-in on the telephone system and sends a confirmation tone to the door speaker. The individual at the phone responding to the signal will determine if access should be allowed. Pressing a programmed code on the telephone dial pad or pressing the remote button will unlock the door to allow admission. The V-2904 also provides an alarm control output to alert an unauthorized entry.
