Warnings

No Safety Switching

Sensys Networks does not allow its equipment to be used for safety applications such

as controlling a mechanical gate or switching a train to avoid a collision.

Lithium Thionyl Chloride Batteries

Sensys Networks uses Lithium Thionyl Chloride batteries in the following products:

Sensors (VSN240-F, VSN240-T, VSN240-S, VSN240-M, VSN240-F-2,

VSN240-T-2)

Repeaters (RP240-BH-2, RP240-BH-LL-2, FLEX-RP-B-2, FLEX-RP-B-LL-2)

Lithium batteries are widely used in electronic products because they contain more

energy per unit -weight than conventional batteries. However, the same properties that

deliver high energy density also contribute to potential hazards if the batteries are

damaged. Improper use or handling of the batteries may result in leakage or release of

battery contents, explosion, or fire.

Following are the recommendations of the battery manufacturer for proper use and

handling of batteries in the Sensys Networks devices mentioned above:

DO NOT charge or attempt to recharge the batteries (they are NOT

rechargeable)

DO NOT crush or puncture batteries

DO NOT short-circuit the batteries

DO NOT force over-discharge of the batteries

DO NOT incinerate or expose batteries to excessive heating

DO NOT expose battery contents to water

DO dispose of batteries and devices containing batteries in accordance with

local regulations

OTE

Sensys Networks wireless sensors contain no serviceable parts and should never be

disassembled. Installation and removal of sensors from pavement should only be done by

trained personnel and care should be taken to insure that the sensor casing is not punctured

or crushed.

Additional safety information is available from the battery's manufacturer:

Chapter 2

Overview

This chapter provides an overview of the contact closure card and describes the

contents of a product shipment.

Contact Closure Master Card

The Sensys Networks VDS240 wireless vehicle detection system detects the

presence and movement of vehicles with magneto-resistive sensors mounted in

the pavement. Wireless sensors continuously transmit detection data to access

points that collect and forward data to remote traffic management systems or

local traffic signal controllers such as the CalTrans Type 170, Type 2070 ATC and

NEMA TS-1, and TS-2 controllers.

The contact closure master card (CC card) is a 2-slot wide, rack-mountable,

hardware interface card that provides up to four configurable control channels to

a signal controller and 48VDC isolated power to a access point. The interface

allows detection events collected by the access point to activate contact closure

relay circuits in the controller in exactly the same manner as copper loops.

Installation Guide Sensys Networks, Inc.

Contact Closure Expansion Card

Additional capacity (to handle more sensors or controller channels) is provided by

a contact closure expansion card (EX card). EX cards use the same form factor as

CC cards and are daisy-chained to a CC card by front-panel RJ45 jacks or

backplane connectors. Up to 63 expansion cards can be used per CC card.

Figure 2.2.Contact Closure Expansion Card

AccessBox

An AccessBox is a small, 3-port junction device that is mounted inside the

controller cabinet. It provides the following services:

connects an access point to a contact closure master card

isolates and routes power from the controller backplane to the access point

provides a wired port for IP network access (suitable for network

configuration, management, and data acquisition)

Figure 2.3. AccessBox

Contact Closure Card Package Contents

Each contact closure card is shipped with the items listed below. Verify that you

have received all of them. In the event that some items are missing, contact Sensys

Networks or the party that supplied the equipment to you.

The items in a Sensys Networks contact closure card shipment include:

A contact closure master card (or expansion card)

Contact Closure Card Installation Guide (this document)
