Take the time to review this manual thoroughly before performing any necessary work. Do not attempt to install any safety system without proper instructions. Product Description The Terminus CEN End Terminal is a crash worthy steel-post, energy absorbing terminal designed to enhance safety at the beginning and end of highway safety barrier. The Terminus CEN End Terminal has been successfully tested to the P4 performance class (110 km/h) and the P2 performance class (80 km/h) using the CEN criteria described in EN For a list of the tests, see the Limitations and Warnings section of this manual. The Terminus CEN End Terminal uses a 'directional' breakaway post concept to support the rail sections. The Lower Post, having a 'U' section is driven into the ground. The Upper Post, with its 'U' section, slides into the Lower Post and is secured using a steel Tension Bolt. During a head-on impact, longitudinal forces break the Tension Bolt, releasing the Upper Post. Energy absorption is achieved through clamping forces between the rails and deformation of the rail sections as they slide rearwards. During a side impact along the Terminus CEN End Terminal the Upper and Lower Posts are designed to remain together, laterally supporting the rail sections, so that the impacting vehicle is smoothly redirected. The P4 performance class system has a nominal length of 12.4 meters and a nominal rail height of 760 mm. The P2 performance class system has a nominal length of 4.4 meters and a nominal rail height of 760 mm. 2

9 P4 System Installation (cont d.) 1.0 Determine Post Locations 1.1 Using a straight edge or plumb line down the existing guardrail face (i.e., traffic side) to the ground, create a datum line (DT1) on the ground. Ensure that this line is parallel with the existing guardrail face. Extend this line ~14 meters upstream of the end of the existing guardrail. Verify that the datum (DT1) remains parallel to the existing guardrail. [Refer to Figure 2] Existing Guardrail Straight Edge or Plumb Line DT1 Figure 2 9

10 P4 System Installation (cont d.) 1.2 A new guardrail post must be driven into the ground at the end of the guardrail panel. The edge of this new guardrail post must be offset from the datum line DT1 towards the existing guardrail by a distance of 210mm (this offset is needed in order to attach a Spacer between the guardrail post and the guardrail panel). It should be noted that the centerline of this new guardrail post may not align with the existing guardrail posts or with the Terminus CEN End Terminal posts. [Refer to Figure 3] 1.3 Measure perpendicular from the datum line (DT1) towards the existing guardrail 250mm and make a mark (M1) near the first guardrail post. [Refer to Figure 3] Note: Any variation of system post pitch at the end of the guardrail system caused by the addition of the new guardrail post must be evened out to reduce pocketing effects. If the dimensions to the end guardrail post is greater than the system post pitch then adjust by not more than one working width difference the adjacent downstream post. First Guardrail Post DT1 M1 210mm to edge of first guardrail post 250mm to mark M1 Figure 3 10

11 P4 System Installation (cont d.) 1.4 Locate the first post of the Terminus CEN End Terminal (i.e., Post 1, refer to Figure 1): First measure from mark (M1) a distance of 12m upstream and make a second mark (M2) which is perpendicular to datum line (DT1). Verify the perpendicular distance of 250mm from mark (M2) to the datum (DT1). Adjust mark (M2) if necessary. [Refer to Figure 4] 1.5 Chalk or stake a line from mark (M1) to mark (M2). This will be the centerline for the posts. [Refer to Figure 4] 1.6 From location (M2), measure off the rest of the post locations (i.e., Posts 2 to 6, refer to Figure 1), towards the first guardrail post, at 2.0m intervals (6 total post locations).
