VANDAL RESISTANT ONE BUTTON DOOR ENTRY KIT VR4K-1 TECHNICAL MANUAL EDITION 1.1 MANUAL INTRODUCTION The information in this manual is intended as an installation and commissioning guide for the vandal resistant one button audio intercom kit. This manual should be read carefully before the installation commences. Any damage caused to the equipment due to faulty installations where the information in this manual has not been followed is not the responsibility of Videx Security Ltd. VIDEX run free training courses for engineers who are not familiar with the Videx product range. Technical help is also available on 0191 224 3174 during office hours or via e-mail tech@videx-security.com. SYSTEM INTRODUCTION This kit will enable a caller at an entrance point to signal an occupant in the dwelling by pressing a call button which will send an electronic call tone to an audio telephone. A Yellow ‘SPEAK’ LED will indicate the call has been answered and a two way conversation can take place, the occupant can release an electric lock release by pressing a button on the telephone base unit. The kit does not include the electric lock release. A 12V AC release should be used with this kit (The output for the lock is a dry contact relay so any other type of lock can be used with an appropriate PSU). If this kit is to be used with a gate, the dry contact output can be used to trigger the gate control board. DDA features such as a ‘SPEAK’ LED, ‘DOOR OPEN’ LED and reassurance tones are standard on this kit. SYSTEM COMPONENTS This kit comprises of a flush or surface vandal resistant door panel, audio telephone and PSU. Up to a maximum of three telephones can be used on the system to call in parallel. DOOR PANEL The vandal resistant door panel will consist of an amplifier module, button, vandal resistant plate, frame and back box. Dimensions Surface Audio panel Flush Audio panel PANEL FLUSH BACK BOX 135mm(W) x 160mm(H) x 43mm(D) 135mm(W) x 160mm(H) x 16mm (D) NA 120mm(W) x 143mm(H) x 30mm(D) Dip-Switches The four way dip-switch bank has the following functions. Please note: dip-switches must be set before power up. Any changes made when power is on will not take effect until a power down reset.

The dc outputs are designed to power the amplifier modules only and must not be used to power other devices such as lock releases etc. These items must be connected to the AC output of this power supply or an auxiliary power supply.

Heavy duty conductors on wiring diagrams are shown heavily outlined, these wires should be doubled up. - Check that all components are free from damage before installing (Do not proceed with installation in the event of damage). Keep all packaging away from children. Do not obstruct the ventilation openings or slots on any of the devices. All connections to mains voltages must be made to the current national standards (IEE Wiring regulations) Install an appropriate fused spur or isolation switch to isolate the mains. Isolate the mains before carrying out any maintenance work on the system. All intercom and access control cables must be routed separately from the mains. When the panel is mounted on an uneven surface, use additional sealant to protect from water ingress. ~~ Lock release back EMF protection : A capacitor should be fitted across the terminals on an AC lock release as shown in the diagram below to suppress back EMF voltages.

These connections are shown heavily outlined on the wiring diagram. 50m 100m 0.5mm² 0.75mm² Connections The power supply should be located as close to the door panel as possible for best performance. Maximum acceptable resistance for above cables = 3Ω TESTING THE INSTALLATION - Check all the connections have been made correctly and dip-switches have been set and then power up the system. Call the apartments. Check for call to the apartment, speech in both directions and lock release and correct operation of the SPEAK & DOOR OPEN LED’s. If the volume of speech needs to be adjusted, this can be done by adjusting the presets on the rear of the amplifier at the door panel. PANEL CARE The door panel is manufactured from 12 Gauge 304 grade stainless steel. It is important that the facia is cleaned on regular occasions to prevent dirt build up and tarnishing of the metal. A general household metal polish can be used but care should be taken to follow the grain of the metal when polishing and also avoid any polish build up around the call button which may prevent the button from operating correctly. ACCESSORIES CONNECTION GUIDE 512A Extension sounder PAGE 5 of 8 VR4K-1 TECHNICAL MANUAL ES/1 Extension Strobe VER1.1 WIRING DIAGRAM o A normally open push to exit button can be connected across PTE & - on the door panel. o When triggering a gate, use C & NO as dry contacts. o When using a fail safe lock release use a separate DC PSU and the NC connection instead of the NO connection. o Remember to fit the 0.1uF capacitor across the lock release.

This should be there all the time and comes directly from the PSU. Lock will not operate from telephone Check terminal 5 on the telephone. This terminal shorts to terminal 3 of the telephone when pressed (Becomes 0V) and sends a 0V to terminal 5 on the VX136 amplifier at the door panel which in turn triggers the relay Check the relay on the VX136 is energising. Use a continuity meter to check the switching.
