1. When two sensors are used they must be connected in series to the master not connected in parallel It is advised that you tape down the sensor on the surface in the approximate location that you plan to install at Connect it to the master and verify that detection zone is where you want it to be and that moving objects such as a gate are not picked up by the sensor You may need to adjust the sensitivity and the placement of the sensor to get the desired detection zone Be careful to insure that during your testing that vehicle tires do not run over the sensor itself while it is taped down This will destroy the sensor Type of Wire Used The sensors are provided with 75 feet of lead in cable and this is usually sufficient for most installations However if additional lead in cable is needed a two conductor twisted pair cable should be used This cable should have a jacket rated for wet locations as most conduits will eventually fill with water at some point The gauge of the wires in the lead in cable to use depends on distance in cable feet from the sensor to the detector The gauge of the wires within the cable can be 20AWG as long as the detector is within 100 feet of the sensor in cable distance For 100 to 200 feet use at least 18AWG wires At greater than 200 feet use a 16AWG wires at a minimum DSP 13 User Manual Page 10 of 15 DSP13_MAN_B Installation Practices The sensors can be installed in several different ways depending on th2. if a vehicle arrives when the unit is without power when power is restored the TRIAD system will show detect if there is now a vehicle in the detection zone DSP 13 User Manual Page 3 of 15 DSP13_MAN_B 3 Technical Data Functional Data Sensitivity Pulse Output Response Time Vehicle Hold Time Electrical Data DSP 13M Operating Voltage DSP 13M Operating Current DSP 13M Output Rating Maximum Number of Sensors Sensor to Sensor Proximity Environmental Data Operating Temperature Storage Temperature Humidity DSP 13 User Manual Ten sensitivities selectable for presence or pulse modes of operation Level 5 should be sufficient for most applications 250 milliseconds Activation 15 milliseconds minimum 55 milliseconds maximum Deactivation 15 milliseconds minimum 135 milliseconds maximum Indefinite depending on environmental noise conditions 8 volts to 30 volts DC 60 milliamps maximum and includes all current used by the sensors The output is an open collector output rated for sinking up to 50 milliamps It is not an isolated output and is referenced to pin 10 Common of the DSP 13M A DSP 13M Master can support up to two DSP 13S Sensors connected in series The sensors are passive measurement devices and as such will not interfere with other sensors at any distance 35 F to 165 F 37 C to 74 C 40 F to 176 F 40 C to 80 C Up to 95 relative humidity non

LED will begin flashing at a 5 Hz rate 100 milliseconds on 100 milliseconds off This indicates that the reset switch must be pressed to send the new sensitivity setting to the sensor and stop the flashing Returning the sensitivity to the original setting will also stop the flashing When the detector is in presence mode the LED will be on while a vehicle is in the detection zone In the pulse mode the LED will turn on for 250 milliseconds with the output off for 250 milliseconds and then show the occupancy display until the vehicle exits When the detector is operating in the pulse mode of operation and the detection zone is currently is occupied the LED will be turned on to a dimmer level than normal and the LED will be flashed at a very fast rate that will make it look like it is flickering This display is meant to be easily distinguishable from the normal on display With this additional display mode the pulse mode of operation can easily be monitored for correct operation A look at the following figure will show how this occupancy indication is used to provide additional information during pulse mode operation In the figure the occupancy display is shown as the gray shaded area 250ms Page 9 of 15 DSP13_MAN_B 5 Installation Detector Installation Location The detector should be installed in a weatherproof location that is near the detection zone Ideally a technician should be able to see the detection
