- Page 2 6 below. Each RTM500 interface card can support up to 4 RTM300 sensors. Each sensor takes power and set up data from, and signals detection events to, the interface card over a two wire link which may be either new or legacy loop feeder cable.

Page 3: Installation
6.1 INSTALLATION OF THE RTM300 SENSOR 6.1.1 The installation of the RTM300 sensor presumes that a suitable duct has been installed, has sufficient capacity and is accessible. Where more than one sensor is to be installed in the same duct, install the furthest sensor first and work progressively to the nearest sensor. - Page 4 Where using legacy loop feeders, it is possible to common all the RTM300 cable low sides onto one core. See Appendix 2.
- Page 5 RTM500. 6.2.3 When all the RTM300 sensors have been installed and fitted, the RTM500 interface card can be inserted and the front panel screws that retain it can be tightened.
- Page 6 Figure 2 - RTM500 Interface Card Front Panel Showing LEDs and Switches Reset Button. Short press (<3s) to re-alight LEDs after power save. Long press (>3s) for full reset. Yellow Fault LED. Lit for channel on & no fault. Flashing for fault. Red detection LED.
- Page 7 A short flash on the red detect LED will appear on the adjusted channel or channels only, which confirms that the RTM300 sensor has received the new sensitivity setting. All other channels which have not been changed are not reset and will keep detecting even during the reset period.

Page 9: Important Notes
Appendix 1 - TR2512 Typical Standalone Backplane Connections The following diagram is representative of a typical standalone backplane. If in any doubt about the connections, the backplane and/or controller manufacturer’s handbook should be consulted. The RTM500 uses opto-isolated open collector transistor outputs, NOT relays. IMPORTANT NOTES For Issue 3 and below hardware versions of the RTM500 Interface Card:- There is NO change-over signal between the open to detect and close to detect... - Page 10 Appendix 2 - Commoning Feeder Cable Cores Although the RTM300 sensors are polarity independent, the RTM500 interface card drives the sensors with a supply and return line. Any number of sensors on one interface card can therefore be commoned so that for all four channels, only one common core and four sensor cores are needed - a total of five cores.
- Page 11 Suitable sized pieces of bubble wrap or foam are suitable for this purpose. Alternative to Ducts The RTM300 sensor does not have to be installed in a duct, and due consideration should be given to alternative installation locations as follows: ...
- Page 12 In some applications it may be acceptable to fit the sensor within a chamber or pit using spring clips fastened to the chamber or pit wall. Certain kerb materials are designed with a bore and may accept an RTM300 sensor.
- Page 13 Appendix 4 - Changing the Zone of Detection There are several ways in which the zone and range of detection can be adjusted, as follows: Sensitivity The higher the sensitivity setting, the wider the zone of detection. The sensitivity should be set so that small vehicles (or those with small ferrous content) are detected reliably, but larger vehicles in adjacent lanes are not detected.
