1 - 08/03 VH30AK B&W Video-Intercom System Door Release Button Intercom Handset / (Key Symbol) 4" (diagonal) B&W Video 'Flat' Screen Contrast Brightness Vertical Hold Not Used (Simulated Picture. NOT shown actual size) APPLICATION The Alpha Communications®/S.T.R.™ VH30AK series B&W video-intercom system uses the most advanced technology available for positively identifying visitors to a building, and securing the residents. Visitors call from one or more lobby entrance stations, and the system will automatically switch all voice, video and door release functions to the calling entrance. The video image will appear automatically, once a call is placed, and residents can discretely 'screen' their calls, before answering. If a resident chooses to reply, all they need to do is lift the voice handset and speak normally. Once a visitor is positively identified, the resident can activate the entrance door release, by depressing the Door Release Button for a few seconds. With the S.T.R.™ VH30AK, Seeing is Believing!!!! Copyright© 2003, Alpha Communications®, All Rights Reserved OPERATING INSTRUCTIONS AT THE ENTRY STATION: 1. Momentarily depress button (for a few seconds) for apartment you wish to call. This will signal the buzzer (or optional Alphatone™) signal at the apartment monitor handset, and will cause the video screen to light and display the visitor. 2. Reply in a normal voice when spoken to. Visitor reply is handsfree (unless a privacy handset is provided at the entrance station). 3. When door release activates (buzzes), enter through door. AT THE VH30AK MONITOR STATION: 1. You will hear a buzzer (or electronic chime sound) when a visitor presses your button at the entrance station. 2. View the visitor on the B&W video screen. You may adjust the picture brightness, contrast and/or vertical hold as desired, using the front mounted rotary controls on the video monitor. 3. You may choose to ignore the caller, or lift the intercom handset to answer. Speak to the visitor in a normal voice. Make sure you positively identify all visitors before activating the door release... or do not open the door! 4. Only if you are satisfied with the identity of the visitor, momentarily depress the door release (KEY) button on the handset, which will electrically activate the door release mechanism. Activating the door release will not shut off the video picture. Video monitor will time-out automatically after approx. 40 seconds (unless the time-out duration has been changed by the installer/ user). In systems with multiple door entry stations, the system will automatically switch the voice, video and door release functions to the last entry station that placed a call.
