The range includes On Crossing, Kerbside, a range of Vehicle Approach, SCOOT & MOVA and Stop Line Data detectors. The detector is housed in a low profile enclosure to minimise ‘eye clutter’.
PAGE 16
Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 2.2 Identification Label Each detector has an identification label affixed to the back of the unit, which identifies the detector type, part number, any optional extras and serial number. Figure 2 – Example (SCOOT) Detector Product Label Figure 3 Figure 4 2.3 Interface The Heimdall detector has three main interfaces. LED An LED indicator is mounted on the side of the detector which gives a visual indication of the detector status.
PAGE 17
Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 2.4 Product Options There are several additional interface options available. These are identified as follows; SiTOS Serial Interface The SiTOS interface provides a facility to transfer detailed detector status / information to a controller equipped to use the SiTOS (serial) communication protocol.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 4.8 General Detector Configuration Facilities 4.8.1 DIP Switches All Heimdall detectors are equipped with switches that enable the unit to be installed, for the majority of applications, without the need for any special terminal (handset) equipment. Access to these switches is gained by removal of the side access door. This comes with a ‘built-in’ retention mechanism to prevent it falling to the ground when removed from the body.
PAGE 35
Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 4.8.2 Terminal Interface All Heimdall detectors are equipped with a terminal interface that will enable the unit to be configured with a terminal interface. The use of a terminal interface cable is required. Access to the terminal interface is gained by removal of the side access door. This comes with a ‘built-in’ retention mechanism to prevent it falling to the ground when removed from the body.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 5.7.4.2 Cranked Pole Installation- Recommended The Heimdall Kerbside detector can also be installed on a cranked pole. This installation is also suitable as it ensures the detector has a clear view of the detection area. The Heimdall Kerbside extension bracket can be used in this scenario. The installer should reference Table 9-1- p105 for support equipment part numbers.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 5.7.4.9 Site Calibration The Kerbside Detector needs to be calibrated to the background noise for each site before it can work to its optimum performance. This calibration needs to be carried out for any changes of the detectors orientation or other changes to street furniture on the pole or in the zone.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER (3) Do the same next to the push button and at various points in the expected zone. (4) When you’re happy with the performance of the detector, remove the ‘Inline Installation Assistance Cable’ if fitted and plug the detector back in. The detector will use the previously calibrated values when it starts back up.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 7.2.1 Managing Sites Prior to attempting communication with the on-site equipment, you need to create and select a 'site' definition file, using the Siecom software. A site will normally be associated with each detector location. A ‘site’ definition file contains information on the communication method, wireless address (where appropriate), equipment type, communication settings, and any additional useful reminder information. 7.2.1.
PAGE 82
Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 7.2.1.4 Site Definition File Properties Info Tab: Site Id This is the unique site reference identifier and will be used as the default file name for the site definition file. This can also be used in scripts. Name A user friendly name for the site which can also be used in scripts. Description This gives the user information regarding equipment configuration, location, etc.
PAGE 83
Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 7.2.2 Site Connection Once a site file has been successfully opened it is possible to connect to the equipment by selecting Site Connect from the menu. For wireless connections this can take a number of seconds especially if the Bluetooth is switched off, and also depending on the current environmental conditions. It is recommended to start at a close distance for the first connection to ensure range is not an issue.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 7.3 Access Levels This section describes how to use the terminal to view and modify data within the Detector. There are two levels of access as follows: Level 1 (R) Read Only Level 2 Modify/Initialise data items. Access Level 1 (R) No special access codes are required for Access Level 1 as it is ‘Read Only’ and does not change any detector data/configurations etc.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 7.4 Command Format All operator commands start with a three character command code (mnemonic) indicating the parameter to be monitored or changed. See Section 7.7 for a full list of commands. This mnemonic is normally an abbreviation of the associated parameter making them easier to remember, for example, entering the mnemonic ‘DOS’ displays the Detector Output Status on the User Terminal.

Siemens Mobility, Traffic Solutions Sopers Lane, Poole, Dorset BH17 7ER 8.4.4 Historic Rolling Log The Heimdall detector contains a ‘rolling’ historic log that records the elapsed time when various events occurred. This elapsed time is defined as the period of time after the detector was initially installed and is presented as: Years: Days: Hours To display the log entries, the terminal command ‘FLG’ is used. See the ‘FLG’ command for further details on operation (reference section 7.7).
