UNIVERSAL FOUR DOOR ANSWERING SYSTEM

INTRODUCTION

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 dialpad 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.

These instructions contain the specifications and

information necessary to install, operate and maintain

the Universal Four Door Answering System.
