The STR QwikBus™ takes advantage of the latest in digital technology to provide a high tech, high quality black & white video intercom system operating on a 4 common wire BUS.

QwikBus™ video monitor stations feature a crystal clear 4" video screen (measured diagonally) with handset as well as audio only stations that can be mixed and matched to suit your particular application all on the same 4 twisted wires.

PLANNING THE INSTALLATION

Is this a Black & White Video installation?

This manual is written expressly for the QwikBus™ 4-wire Black and White system that will be using the Inside monitors listed on the previous page. If you are installing a Color system please refer to the QwikBus™ 2-wire Color System 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.

How many apartments will need more than 1 monitor?

An apartment can have up to 5 monitors and or audio stations that will ring when the entry button is pressed.

How many Entrances?

QwikBus™ can have up to 8 Entrance panels. If you will be installing a larger number of entrances please contact Alpha Communications® for design assistance.

Modular Panel?

STR modular panels are available in White, Titanium, and Dark Brown and are usually used in small installations from a 1 button residential application up to multi-apartment configurations and feature beautiful contemporary looks, illuminated buttons, and outside weather resistance.

Stainless Steel or Brass Panel?

Alpha Communications can custom build flush and surface mount entry panels in Stainless Steel or Brass with all necessary apartment button numbering and address engraving.

How many observation cameras will be in the system?

Additional Cameras can be added in addition to the Entrance Cameras for a total of 8, enabling the apartment monitors to view the various feeds on demand.

What type of Inside stations will you use? Although all the compatible stations connect the same way, each model does have

certain capabilities and advantages depending on the needs of the tenant and can be exchanged for another unit at anytime if necessary by simply installing the 4 wires and reprogramming the system to recognize the unit.

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 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. If the existing wiring is more than 12 years old, has deteriorating insulation, questionable splice connections, corrosion, or is not configured as twisted pair wiring, it is highly recommended that new wire be run.

To reduce the risk of interference problems:

• Always use a single twisted pair wire for the two wire BUS line.

• Do NOT double wires to increase effective wire diameter. This will cause interference

problems.

• Do NOT install any unused additional wires with open ends.

• Never connect the shield from a cable, or connect the shield from one cable to

another.

• Use a separate cable to the door strike from the SP333.

• Only use a 12VAC door strike or 12VAC relay with less than 1 amp draw.

• If it is absolutely necessary to run the door strike wiring in the same cable as the BUS

line, you must use a transient voltage suppressor at the door strike end.

• Loop resistance should be less than 20 ohms.

Twisted pair is always recommended.

Cat5, Cat5E, Cat6, and the new Cat7 spec. wire is NOT recommended.

How many risers will you be using? The recommended maximum number of monitors on a riser is 10 with each riser originating

from the SP333 Control Unit, or from the EVB333 Amplified Splitter(s) if your system requires them.

System Notes – 4 wire Black & White System 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 8 Dipswitch Settings. Be sure that the End of Line Jumpers are used on the camera circuit board and in the last

monitor on each riser. If the last unit on a riser is an audio only unit, the End of Line Jumper would still be used on the last

monitor on that riser. This is important for best picture quality.

(refer to Page 10) End of Line Jumper Locations.

When connecting C333-2 harness between SP333 and SNT333, ALWAYS observe 24VDC Polarity.
