The STR QwikBus™ takes advantage of the latest in digital technology to provide a high tech, high quality color video intercom system operating on a 2 common wire BUS. QwikBus™ video monitor stations all feature a crystal clear 4" LCD Color screen (measured diagonally) and can be surface or flush mounted (with optional UMV1000 flush housing).
PLANNING THE INSTALLATION Is this a COLOR Video installation? This manual is written expressly for the QwikBus™ 2-wire Color systems that will be using the Inside monitors listed on the previous page. If you are installing a Black and White system please refer to the QwikBus™ 4-wire Black & White Manual. How many apartments? QwikBus™ can run up to 120 apartments and can exceed that number if specially designed. If you will be installing a larger system please contact Alpha Communications® for assistance.
Are you running new wire or using existing wire from a previous system? Although digital systems are fairly forgiving in wiring requirements, they are still susceptible to RFI from unusually strong nearby transmitters, EMI from electrical lines running nearby, or existing wiring that is not twisted, in poor condition, or not a suitable gauge. Please refer to the wiring thickness chart below to determine the minimum recommended wire gauge needed.
System Notes – 2 wire COLOR with Single Modular Entry A Single Entry Modular system requires the following dipswitch settings on the back of the TSMB3 unit: Switches 4, 5, & 6 identify the entrance number (all OFF = Entrance 1) Switch 3 If the door strike is to be connected to the SP333 (Tö1) = OFF If the door strike is to be connected to the TSMB3 (Tö) = ON For more information refer to Page 10 - Dipswitch Settings.
System Notes – 2 wire COLOR with Multiple Modular Entries Multiple Entry Modular systems require the following dipswitch settings on the back of the TSMB3 unit: Switches 4,5, &6 identify the entrance number.
System Notes – 2 wire COLOR with Single Custom Panel Entry The TT33 SPEAKER/MICROPHONE/ CONTROLLER allows you to use QwikBus™ with a custom panel or existing dry contact type entry panel by converting the button presses to a digital signal through an electronic matrix. This matrix is discussed in detail on Page 13.
System Notes – 2 wire COLOR with Multiple Custom Panel Entries Multiple Custom Panel Entry systems require the following dipswitch settings on the back of the TT33 units: Switch 3 If the door strike is connected to the SP333 (Tö2) = OFF (as shown at Entrance 2) If the door strike is connected to the TT33 (Tö) = ON (as shown at Entrance 1) Switches 4,5, &6 identify the entrance number.
System Notes – 2 wire COLOR: Important Information on Monitor Riser Connections This section discusses the proper procedure for connecting monitors on a riser. Although a digital system is very forgiving, it is best to follow these rules during installation to maximize performance and minimize potential problems. Using existing wiring: When using existing wiring there are many things that can cause problems. The first is of course, wiring condition and gauge.
All Monitor BUS lines must be terminated with an End of Line resistor on the last monitor in the run. This is built into each monitor and can be installed by putting a jumper connector on J1. The location of this jumper is illustrated on Page 12. If a BUS is not terminated properly, the electronic characteristics of the line will change resulting in signal degradation and poor video quality.
Dipswitch Settings – Entries & Door Strikes The QwikBus™ system uses dipswitches for identification of Entry stations, additional cameras, and to enter “Programming Mode”. Entrance Panels must have a unique code so the system knows where the call is coming from and which door to open. Dipswitches 4, 5, & 6 on the back of the Speaker/Microphone Unit (TSMB3 (Modular style) or TT33 (Custom style)) assign this code as shown in the chart below.
Entrance Panel Cameras When using a Modular system, The Modular Camera (KMBC3*) is automatically identified by being connected directly to the TSMB3 and takes the same Entrance number (1-8) of the TSMB3. When using a Custom Panel with a TT33 Speaker/Microphone/Controller, You can use either a pinhole or CCTV type analog camera with it’s own power supply for system video input.
BUS End-of-Line Resistors – Jumper Locations For proper system operation, the last video monitor on a BUS riser as well as the last camera on a run must have an End-of-Line Resistors. These resistors are built in to the printed circuit boards and can be connected by installing the jumper on the two pins labeled J1. Usually these jumpers are supplied on all the monitors and camera boards and must be removed if the unit is not the last camera or monitor connected to the BUS line.
The Matrix – Wiring Pushbuttons to the TT33 When using an STR Modular Button assembly, the system can read which switch is being pressed by electronics built into the switches. In the case of a Custom Panel, these electronics are built into the TT33 and you must run wires to assign each button to a position in a matrix. Modular Button Assy. Close up of TT33 Matrix Connections The matrix consists of Common Connections a,b,c, & d and numbers 1 through 6.
The IC2 Database Chip The QwikBus™ system has 8 pin nonvolatile IC chips located on the back of each TSMB3 Speaker Microphone Module (in the Modular style Entry Panels) or TT33 Speaker Microphone Module (in the Custom style Entry Panels). Each unit has this chip which maintains the programming for that specific entry. If you have to replace a TSMB3 or TT33 unit, you can remove the IC2 from the old unit and install it into the new unit so you do not have to reprogram that entrance.
PROGRAMMING SECTION for OPEN VOICE STYLE NOTE: Depending on your choice of Entry Panel, you will either be using a TT33 or TSMB3 Module. The TT33 and the TSMB3 will both be referred to in this section as the Speaker/Microphone Programming the QwikBus™ System -- Open Voice (VFS1500/1000 FS1500/1000) Programming the system is easily done with two installers. One to move from apartment to apartment working with the monitors, and one to be at the entry panel pressing the corresponding buttons. 1.
One Man Bench Programming -- Open Voice (VFS1500/1000 FS1500/1000) If you prefer, the system can be preprogrammed on the bench to minimize your on-site time and eliminate the necessity of a second installer. To do this the inside stations can be connected separately one after another to the Speaker/ Microphone Module (either the TSMB3 or the TT33) using the special programming cable (Part # EMPK-VFS/FS), or just using 2 wires between the BUS terminals of both.
Programming Open Voice VFS1500 for Intercommunication You can install up to five VFS1500 stations and program them for intercommunication in the same residence/ apartment. To program a VFS1500 to ring when one of the numeric buttons on another unit is pressed: 1. At the Calling station, press and hold the button you wish to call the second station until you hear a short tone. At this time the red LED will be blinking indicating that the first station is in programming mode. button.
PROGRAMMING SECTION for HANDSET STYLE NOTE: Depending on your choice of Entry Panel, you will either be using a TT33 or TSMB3 Module. The TT33 and the TSMB3 will both be referred to in this section as the Speaker/Microphone Programming the QwikBus™ System – Handset Style (VHC3033-2 / HT3033) Programming the system is easily done with two installers.
