Versus Technology, Inc. Collector - This device gathers the tracking data from as many as 24 Sensors, processes it as required, and sends it via the 2-pair collecting network to the concentrator. Each system must contain at least one collector, and many systems will contain more than one. Sensor - A sensor is a device that gathers infrared light energy and converts it to an electrical signal, which is then sent over a single pair of wires to a collector.
Versus Technology, Inc. Balun - This is a small electronic winding which interfaces a 93 ohm unbalanced signal (coaxial cable) to a 100 ohm balanced line (twisted pair) or vice-versa. Its name is a melding of the terms "Balanced-to-Unbalanced", or "BalUn". Modular Patch Block - This is a device which plugs into a Collector just like a punch block does only it provides twenty four modular RJ-12 style jacks instead of punch terminals.
Versus Technology, Inc. 2. SYSTEM HARDWARE DESCRIPTION This section contains a description of the system, which will aid in the understanding of the methods required for proper installation. 2.1 General The system is a unique, reliable, flexible platform for locating personnel and equipment, in addition to relaying event and control information throughout a building. The system transfers information using battery-powered, infrared (IR) badge transmitters and IR sensors.
Versus Technology, Inc. 2.3 Badges The badge is a small unit worn by personnel or attached to equipment. This device sends an IR signal to the sensors installed in each room. This signal contains encoded digital information that is used to identify and obtain the status of the badge. Motion, timing, battery state, and auxiliary information are all included in the signal. The badge sends its IR signal from two emitters located at the top left and right corners of the badge case.
Versus Technology, Inc. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference, and 2) this device must accept any interference received, including interference that may cause undesired operation.
Versus Technology, Inc. 3. PLANNING AND INSTALLATION GUIDELINES 3.1 General This section contains a description of the system, which will aid in the understanding of the methods required for proper installation. When planning an installation, certain rules and limitations must be observed. The equipment has been designed to provide trouble free operation in various environments, and adherence to the guidelines is critical for a reliable installation.
Versus Technology, Inc. 3.2 Collector Network Length Limitations There must be no more than six (6) collectors on any one concentrator as shown in the RS-485 loop display below. The total length of the collector network must not be more than 4000 feet. See Figure 3-2 for a visual representation. Figure 3-2 NOTE: The total length of an Ethernet network must be no more than 3000 feet. Consult the Ethernet manual for more information on installation procedures. 3.
Versus Technology, Inc. NOTE: *** Collectors may be affected by high watt radio or paging antennas.*** DO NOT PLACE A COLLECTOR IN CLOSE PROXIMITY TO ONE OF THESE ANTENNAS Internal Concentrator VER-2020 Note: If you are not using an Ethernet or Arcnet external concentrator and your site is less that 150 sensors then you may choose to use an Internal Concentrator (a plug-in PC card) instead. 3.
Versus Technology, Inc. 3.7 Effective Coverage of Rooms When planning the location of a sensor in a room, one should take into account the human factors involved. The majority of activity in most offices occurs towards the center of the room, and people do not often stand in corners, or near walls. A single sensor placed near the middle of the ceiling area can usually effectively cover a normal office or meeting room. If the office is oddly shaped or very large, two sensors may be required.
Versus Technology, Inc. 3.8 Special Problems with Sensor Coverage The placement of sensors is usually a simple matter, but there are some special things to remember when planning a system installation. The system planner should consider that a sensor may have a field of view which extends out of the designated area through a doorway or passage, and that tagged persons might be detected incorrectly and reported to be in the room when only passing by.
Versus Technology, Inc. 3.11 Use of Unauthorized Components Your system is an innovative, high technology system that integrates hardware and software to create a safe, reliable and efficient system. Use of components or connection to equipment not approved by the manufacturer is NOT recommended and will invalidate any and all warranties. Approved third-party components include wire and connectors, terminal blocks, and other interconnection means only.
Versus Technology, Inc. 4. INSTALLATION GUIDELINES 4.1 General When installing a system, certain rules and limitations must be observed. The system is designed for troublefree operation in all environments, and adherence to these guidelines is critical for a reliable installation. The following sections will detail the things that must be included in a system to ensure a successful installation. 4.
Versus Technology, Inc. 4.3 List of Tools Some installation activities require special tools. Refer to Table 4-3 for a list of recommended tools. Table 4-3.
Versus Technology, Inc. 4.4 Safety and Code Considerations Safety procedures and adherence to local building codes are the responsibility of the system installer. Versus products have been designed to be safe and reliable under the conditions in which they are intended to be used. The following sections detail those aspects of the system that might affect safety. 4.5 Equipment Handling The components used in a typical installation contain internal circuits that are sensitive to static electricity.
Versus Technology, Inc. 4.7 Grounding of Equipment All points in a system installation are connected to a common “ground” via their interconnect wires. No attempt should be made to provide any additional earth ground or neutral connections to any sensor or collector. Adding ground connections to multiple points in a networked system may introduce electrical system noises that will interfere with normal system operation. Consult the manufacturer if special grounding requirements must be met.
Versus Technology, Inc. 4.10 Cable Types Refer to Table 4-10 for a summary of the cable types recommended for installation. Approved equivalent types may be used. Approved equivalent cable types may be used. Color coding tables have been included in order to provide a systematic approach to all cabling in all installations. Table 4-10. Recommended Cable Types Sensor Cable CAT 5 Collector Cable CAT 5 Ethernet Cable CAT 5 Intercom Cable 7 cond. with drain, 26 AWG shielded cable 4.
Versus Technology, Inc. 5. CABLE INSTALLATION This section contains tips to aid in the installation of cables. When installing sensor and network wiring, normal telephone installation techniques should be employed. Sensor wire runs should allow sufficient length to move ceiling tiles and perhaps to move sensors if needed. The paragraphs are in order of component type (for ease of identification and discussion of related topics) and are followed by the procedural steps. 5.
Versus Technology, Inc. 6. INSTALLING AND CHECKING SENSORS Sensors are installed in ceiling tiles or ceiling surfaces using a 2-3/8" hole saw. The sensor is placed into the hole and secured using the spring steel clip and the sensor cover to “sandwich” the ceiling tile. The spring steel clip securely holds the sensor against the ceiling tile allowing for easy access for installing or replacing sensors. CAUTION: The sensor casing material is soft and is easily marred and scratched.
Versus Technology, Inc. c) Connect the sensor wire-pair on the collector end to the associated punch-down block pin-pair using the punch-down block tool. d) Mark the sensor as installed on the Installation Checklist. 5. Checking Isolation: In the course of interconnecting many sensors to a Collector, it is not uncommon to make contact with a sharp metal edge, ganged knockout box, or electrical ground with one of the conductors.
Versus Technology, Inc. 7. PUNCH-DOWN BLOCK INSTALLATION AND ORGANIZATION The collector punch-down block is organized so that each two punch-down block rows, starting at the top, left of the block are one sensor port. The last two rows are not used. Refer to the Punch-down Block Diagram (page 21). Bridge-clips are normally used to connect left-side pins to the right-side pins, which are wired to the collector unit.
Versus Technology, Inc. Figure 7-1. Punch-down Block Diagram Sensor wiring should be tested at these pins before bridge clips are installed. Check for isolation at this point. After sensor wiring has been verified, bridge clips are installed across these pins for each active pin-pair. Sensor No. 1 pin-pair, 2 rows Sensor No. 2 pin-pair, 2 rows Sensor connections continue through 24 maximum. Sensor Wire Side Collector side Collector Connection 25th double row of pins is not used.
Versus Technology, Inc. This floor plan and collector table is an example of a punch-down block wiring organization chart. It describes the sensor numbers and the room assignments where each sensor and zone is located on the punch-down block wiring. Figure 7-2. Sensor Wiring Floor Plan See the sensor and punch-down block wiring table on the next page for correct wiring locations and connections.

The punch-down block pair represents a pair of sensor wires. 2.
Versus Technology, Inc. 8. INSTALLING AND CHECKING COLLECTORS Locate the punch block and collector unit(s) carefully to allow for wiring access, neat wire routing and dress, and expansion space for future collectors that may be added as the system is expanded. 8.1 Checking the Collector Wiring A quick visual check of the collector wiring should find that the punch block is secure and that the collector unit connector is firmly seated against the punch block connector. See section 13.
Versus Technology, Inc. 8.3 Setting the "Last Unit" Switch Terminated Unterminated Collector When installing collectors, the collection network wires are run from unit to unit in a daisy chain fashion. Each collector has a small switch on it that is used to identify it as the last collector on a line.
Versus Technology, Inc. CAUTION: A shorted sensor pair will not cause immediate damage to the collector. However, if allowed to remain, some heating of collector components will occur which is undesirable. If shorted pairs are noted in the sensor voltage test, remove the collector power and resolve the shorts as soon as possible. If the system must be powered with the short unresolved, remove the Punch-block bridging clips to disable the disruptive sensor until the wiring can be repaired.
Versus Technology, Inc. 9. COLLECTOR WIRING The collector devices connect to the sensing network using modular interfaces to allow for testing of the wiring before power is applied. It is recommended that installers are equipped with appropriate cable testers to verify the polarity and validity of installed wiring. There are two parallel RJ receptacles on each collector. This allows collectors to be chained together from their assigned concentrator to the last collector in the chain.
Versus Technology, Inc. 6. Mark the collector cable as checked on the Installation Checklist. 7. For each collector perform the following: a) For the collectors identified on the contractual floor plan schematic diagram as LAST, set the UNTERMINATED/TERMINATED switch to the TERMINATED position. For all other collectors, set the switch to UNTERMINATED. b) Insert the RJ plug(s) into the collector receptacle(s) (either collector receptacle is acceptable.
Versus Technology, Inc. 10. CONCENTRATOR INSTALLATION The selection of external or internal concentrator’s depends on the installation. 10.1 Computer Network Card The computer should be equipped with an appropriate network card for Arcnet and/or Ethernet Concentrator installation 10.2 Internal Concentrator Installation The Internal Concentrator is installed inside the computer in an appropriate expansion slot. Follow the standard installation procedures for any computer hardware device.
Versus Technology, Inc. 11. INSTALLING AND CHECKING THE EXTERNAL CONCENTRATOR The Concentrator Power Supply should be secured to the electrical outlet using a screw or other means to ensure that it cannot fall out or is disconnected by others working in the same area. Do NOT plug in the power supply cable until the installation wiring checks are completed. System damage could occur. 11.
