Quick Talk vS WIRELESS VEHICLE DETECTION SYSTEM RVS P1 RITRON VEHICLE SENSOR PROBE INSTALLATION OPERATION INSTRUCTIONS If the Quick Talk transmitter enclosure is mounted outdoors you must seal the antenna connection on the radio Refer to the instructions in the Quick Talk manual page 13 Use Archer Connector Sealant Radio Shack 278 1645 or equivalent Introduction Please read these instructions completely Itis recommended that each system be bench tested prior to installation and that the installer acquaint himself with the Quick Talk vS system The sensor probe detects the disturbance to the Earth s magnetic field caused by moving ferrous metal such as steel or iron The larger the ferrous object and the faster the movement the further away it will be detected This system includes the relay board installed inside the Quick Talk enclosure and the vehicle sensor probe If there are any questions technical support is available to discuss problems and offer solutions Earth Ground A proper earth ground of the probe is essential for the system s lightning protection and EMF shielding Normally burying the vehicle sensor probe is sufficient to meet the grounding requirements However under three conditions the probe must be grounded by attaching it to a separate ground rod 1 in areas with a poor earth ground such as sandy gravel or rocky soil 2 when the probe is inserted in a PVC pipe or 3 the probe is mounted abov
5. Talk transmitter Probe Connections refer to FIG 1 The standard length of cable that comes with the probe is 80 feet longer lengths may be special ordered The length of cable is not critical to performance and may therefore be shortened to any desired length Before attaching leads to the terminal strip it is recommended that all leads probe wire power leads ground lead and relay leads be solder tinned This will insure good contact BATTERY Connect the black wire from the probe to the BLK terminal on the relay board terminal strip the red wire to the RED terminal and the shield wire to the SH terminal GROUNDING PROBE TRANSMITTER ROD TRIGGER CONTACTS Power refer to FIG 1 The control unit can be operated by a power source from 7 5V DC to 10V DC The negative terminal on the terminal strip is common connection for the negative side of the power supply and earth ground refer to Earth Ground The positive terminal on the terminal strip is for the positive side of the power supply NOTE It takes at least 2 minutes after the voltage is applied before the unit can be activated Relay Output refer to FIG 1 The relay output as indicated by COM common and NO normally open is used to activate the Quick Talk transmitter trigger The relay time can be adjusted by potentiometer B TIME Time can be adjusted from 1 2 to 2 seconds NOTE A relay with normally closed contacts is avail
