Videx, VR4KAM-2/Y, Two Button 4000 Series Vandal Resistant Speaker Module with Yellow Enamelled Bezel

VR4KAM-2/Y, VIDEX, TWO BUTTON 4000 SERIES VANDAL RESISTANT SPEAKER MODULE with YELLOW ENAMELLED BEZEL

Vandal resistant speaker unit (2 button) For standard VR4K systems, including video systems . The included speaker unit is an intelligent device with a built-in microprocessor to control the functions of a system.. This speaker unit offers ease of installation (on multiple entrances there are no entrance switchers required) and assists the user by providing visual and acoustic reassurance signals during the process of a call (call, conversation, door open etc).Additionally these buttons have an enamelled yellow ring around the outer edge for use with DDA panels for the visually impaired.

The enclosed speaker unit circuitry includes:

• The microprocessor for controlling all functions;
• The transmitting amplifier with condenser microphone and volume control;
• The receiving amplifier and volume control;
• 3 LED's for Speak, busy and Door Open visual indication;
• The dry contact lock release relay to enable the electric lock or gate;
• The modulated tone generator for calling apartments;
• One 4 way DIP-SWITCH and a jumper to program the unit.

SPEAKER UNIT PROGRAMMING:

The dip-switch and the jumper are accessible from the back of the module allowing the setup of the following parameters:

DIP-SWITCH 4 way:

• The conversation time 1 or 2 minutes (switch 1);
• The door opening time 2,4,8 or 20seconds (switches 2,3);
• The recall on handset pick-up i.e. Speech live when a handset is lifted, on 1 entrance systems only. (switch 4);

JUMPER:

• Reassurance tone High, Low or off

The audio speaker module is the basic unit required to build an outdoor station for an audio door entry system.Amplifier modules are available with 0, 1, 2 and 3 buttons that can be used individually for a 1, 2 or 3 button door entry system or combined with additional VR4KBM button modules for larger systems.

The introduction of microprocessor technology to the standard range of 4000 series audio modules (VR4KAM) forms the building block for the following range of audio and video door entry systems.

• Audio door entry systems with multiple entrances eliminating the need of the audio 2 entrance switching relay (Art.502).
• Video door entry systems using coax or balanced video, eliminating the need of the Art.890 video control unit and on multiple doors replacing the two entrance switching relay Art.892 with one Art.506N relay for each door.

The VR4KAM has a bank of dip-switches for adjustment of the following settings:

• To set the conversation time 1 minute or 2 minutes.
• To set the door lock release time (2, 4, 8 or 20 seconds).
• To set the speech mode.

In addition to the dip switches, two trimming pots are available for adjustment of the microphone and loudspeaker volumes and a jumper to allow for the adjustment of the reassurance tone volume (high, low or disabled).
The two LED’s on the front panel give visual indication to the visitor of the systems operation.

• The yellow speak LED illuminates when the call has been answered and a conversation can commence.
• The green open LED illuminates to indicate the lock release has been activated.
