The purpose of this document is to provide a single reference location for the selection, installation and maintenance of Siemens’ range of traffic signal poles.
1.2 Scope
This document is valid for all UK sites and supersedes all previous guidance issued on traffic signal poles. This document must be used for all current and future installations or modifications. Any required deviations from the guidance given must first have Product Manager and Engineering approval.
1.3 Project Overview
All poles used for traffic signals must be CE marked and deemed fit for purpose. With the vast array of traffic signal equipment available across variable locations, this document specifies the poles available for use with traffic signal equipment as well as any limitations that may apply.
1.4 Document Specific Abbreviations and Definitions

2 CE marking & the Construction Products Regulations The Construction Products Regulations (CPR) are applicable to the installation of specific Traffic Signal equipment and provide a legally binding obligation for manufacturers to provide proof that their products are “fit for purpose”
For Traffic Signal equipment, this primarily falls under 2 categories:
1. The optical and physical performance of the Traffic Signals; these requirements are controlled during the signal manufacture.
2. The structural performance of the poles and/or structures that the signals are mounted on.
Traffic signal poles have historically been considered to be strong enough for any installation condition within the UK. The increase in levels of equipment mounted on signal poles, combined with the increasing use of poles with low level access doors, means that there are more limitations to the amount of equipment that can be mounted.
For Traffic Signal poles to meet the requirements of the CPR, the pole must easily be identifiable such that the performance criteria of the pole can be found. Due to the subtle variations of poles, Siemens have decided that the best way of controlling this is with the use of a label that is to be applied to the top of the pole. The primary performance criteria are defined below and the layout of this information can be seen in Figure 1:
1. Performance under vehicle impact
2. Resistance to corrosion
3. Maximum bending moment
4. Maximum moment for torsion

Traffic Signs Regulations and General Directions (TSRGD) are also legally binding requirements for traffic signal installations in the UK. In addition to TSRGD there are also additional safety considerations included in Section 7.2.4 of LTN 1/98.
Figure 2: Important mounting height regulations
Section 7.2.4 of LTN 1/98 states that there must be:
1. A minimum clearance of 2.1m between the lower edge of the signal assembly (including any additional box sign or support brackets) and the footway should be maintained.
2. It should be noted that increased clearance (2.3m) is needed for three aspect cycle signals and it is recommended wherever cyclists may be present.
3. Where pedestrian light signals (Far sides) are used, they should be erected with a clearance of 2.1 to 2.6 metres to the lower edge of the assembly.
All standard Siemens traffic signal poles offer a minimum of 2.3m clearance between the footway and underside of signal head brackets if they are installed in accordance with the instructions contained within this document.
Where additional signal clearance is requested by the customer, or where straight poles are selected to be used with formed traffic signal poles, there are a range of signal poles that provide a minimum clearance of 2.66m between the footway and underside of signal. It should be noted that the critical clearance distance on a formed poles is the distance from the ground to the crank; therefore consideration should be given to both these areas.

This table defines the pole types and their uses. Poles are not defined by length when they are less than 5m due to the number of variations. Poles 5m and above may vary in length slightly from the value given.
Pole Description
Foundation Type Notes:
Stub pole short Retention
socket only For installation of Nearside demand at low level only in shallow retention sockets.
Stub pole All For installation of Nearside demand at low level
Stub pole for repeater
Retention socket only
For installation of Nearside signal/demand at low level and repeater signal at high level. Less street clutter than using standard pole
Standard Signal Pole
All Previously known as a 4m pole, this pole now varies in length depending on foundation type, hence no longer referred to as 4m
Pedestrian Signal Pole
All Pedestrian signal pole is designed to mount the lower signal at a higher level than standard. These provide the same signal mounting height as a formed pole or to give greater clearance for cyclists.
Formed Signal Pole
All These provide an offset mounting for traffic signals. As the crank in the pole reduces the clearance to the footway, the signals are mounted higher up to maintain clearance for cyclists.
5m Pole All Traditionally used to mount signal heads higher, thus reducing the chances of vehicle strikes.
6m Pole All Allows 2 row of signals to be mounted at different mounting heights
6m Pedestrian Pole
All Same as 6m pole but with lower signals mounted higher up, to match height of signals on Pedestrian or formed poles.
6m Pole (High Strength)
Retention socket only
Same as 6m pole but manufactured from thicker material to allow installation in exposed wind locations or with more equipment.
7m Pole All As 6m pole with upper signals mounted 1m higher
8m Pole All As 6m pole with upper signals mounted 1m higher

4.4 Passive Poles
The general principles described in this document are also relevant to Passively safe poles, however this document only covers poles that are NOT classed as being passively safe.
4.5 Mast Arms
Mast arms are larger structures that offer significantly greater risk if not specified or installed correctly. As such, all mast arms must be assessed on a site-by-site basis by Siemens’ Engineering department or suitably qualified Engineer. All mast arms used in the UK are to be validated against the requirements of Volume 2, Section 2, Part 1, BD94/07 of the Design Manual for Roads and Bridges. An Approval In Principle (AIP), in accordance with Volume 1, Section 1, Part 1, BD2/12 is required for all mast arm installations; these would usually be carried out by the site designer, local authority or pole manufacturer.
Due to the variety of mast arms available there are no standard variants of mast arm currently setup for selection, however suitable structures are available from the suppliers noted below:
Rotating Mast Arm from Volker Highways
Fixed cantilever mast arms from Fabrikat
Fixed cantilever mast arms from Valmont Stainton
4.6 CCTV
CCTV poles are standard signal poles without standard signal fixing holes and with a welded top cap. These poles offer a small belled section at the base of the pole and are strong enough for use with standard CCTV cameras or ANPR cameras. If additional equipment is required to be installed you must obtain approval from the Siemens Engineering Department prior to installation.
It is important to note that these poles are not compliant with the stiffness/stability requirements of BD 94/07, therefore please contact the Siemens Engineering Department for poles that may be suitable for this purpose.

Planted root foundations are planted directly in the ground, surrounded by concrete foundations. These poles are harder to remove or adjust, but as they do not need an additional socket, they have a price advantage over the retention socket solution.
Due to the additional torsional loads applied when using formed poles or straight poles with extension brackets, an Anti-rotation pin - 667/2/10094/000 - must be fitted in the hole indicated during installation.
There is a cable entry slot in the lower section of the pole. The upper part of this slot must always be a minimum of 200mm below ground level; otherwise the strength of the pole will be compromised.

6 Wind Loading Wind loading is calculated in accordance with NA TO BS EN 1991-1-4:2005+A1:2010. The wind pressures calculated using this standard are then combined with the Helios signal head loading data given in 667/AS/47674/000 to determine the suitability of the structure.
Figure 7: Wind area maps for the UK
To simplify the maximum pole configurations that can be achieved without the need to contact Siemens Engineering for approval, The UK has been split in to 3 areas. Each area is then subdivided in to 2 regions, one which is between 0.1km and 4km from the coast and the other is greater than 4km from the coast.
It is important that the maximum signal conditions and altitude (above sea level) that the signals are installed is checked against each table for the different areas. Please refer to the tables in Appendix C. This should be checked at the design stage of the site, but also applies when adding additional equipment.
Any configuration of equipment not shown in this table must be referred to the Siemens Engineering Department for further checks.

Poles should, where possible, be installed without having to modify the length of the pole. This is not only difficult to achieve on site, but it also requires final treatment to ensure the corrosion resistance of the pole is maintained.
Generally cutting a pole to length should only be considered when using a shallow bridge deck socket. In this instance it is preferable to request that Siemens arrange for the pole to be modified via concession in advance of installation. Where this is not possible, consider using approved subcontractors to complete works.
Before cutting, please consider whether there is another standard pole available that will provide the desired results.
If the retention socket has been installed in a hole that is too shallow, please ensure that the foundation volume has not been compromised.
7.2 How to correctly cut poles
Determine amount to remove from the pole
Check that foundations are correctly installed
Check that the reduction in length will maintain the minimum required ground clearance.
Mark pole accurately
Cut pole squarely using approved cutting equipment by a trained, competent and approved operator. (Check NHSS regulations etc.)
Ensure cut is finished square
Deburr edge of pole and ensure that there are not sharp edges.
On steel poles, protect the cut edges with a cold galvanising spray such as Galvafroid – ensure COSHH regulations are followed.

8 Aluminium Poles When installing the pole in the NAL RS115D/F retention socket you MUST face the internal extrusion features towards the oncoming traffic as this will prevent the need to drill through them when fitting the Nearside/Demand
units. See Figure 8.
Important Note: If you were to drill through the internal extrusion features when fitting the Nearside/Demand units the “U” bolt fixings would be moved back into the pole and the threads would be too short.
Figure 8: Aluminium pole profile
8.1 Mounting equipment to Aluminium poles
The Aluminium Poles are able to be used with all existing, Siemens approved, Helios Signal Head brackets, but the insulator fixing kit, 667/1/47910/00, must be used to minimise bimetallic corrosion. This kit includes an IVD plated Stainless Steel U-Bolt that must be used to replace the gold coloured, zinc plated steel U-Bolts, supplied with the traffic signals. The kit also includes two insulating washers that are to be used between the bolt head and inside surface of the pole.
All other devices that would normally be fitted to steel poles using the standard traffic signal mounting holes and plastic spacer bracket (such as WiMag Access Points / repeaters, Heimdalls, Telscan cameras, Communications antennas etc) must use the same insulator fixing kit – 667/1/47910/000.
Any products that clamp around the pole, such as Wi-Mag extension brackets, must use insulator kit 667/1/47910/100 to protect the surface of the pole. This kit contains insulation to fit around the U-bolt supplied with the extension bracket kit.

8.2 Drilling holes for Nearside and Pedestrian WAIT enclosures
Due to the variation of Nearside and Pedestrian WAIT enclosures, combined with the differing site conditions, none of the poles are drilled for this equipment. It is important that the centre of the pedestrian demand pushbutton is installed between 1 and 1.1m from ground level. All belled and LLAP’s are designed such that this can be maintained if the poles are planted at the correct depths. Carry out the appropriate risk assessment prior to drilling and protect all drilled holes with cold galvanising spray such as Galvafroid prior to final assembly. The figures below show Siemens Mk2 mounting holes only.
Traditionally, all traffic signal poles are terminated at the top of the pole, in the top cap assembly. Due to the risks of working at height, low level terminations should be considered as an alternative to this on ELV solutions. Refer to the Helios handbook – 667/HB/30000/000 for more details of this mounting method.
9.2 Low level terminations
The Siemens Low Level Access Pole (LLAP) was designed to fit the NAL termination enclosure. This enclosure will also fit within the Siemens range of belled poles if no wooden board is fitted.

10.2 Brackets (Signal Head)
10.2.1 Standard Steel (Galvanised) Mounting Brackets
The brackets supplied with our standard range of traffic signals are manufactured from spun galvanised steel that is powder coated black. These are suitable for use in most applications however where additional protection against corrosion is required, Stainless Steel brackets can be used, see below.
Where individual brackets are required, these can be ordered separately under the following part numbers:
667/2/30070/002 Signal head bracket 2 Aspect
667/2/30070/003 Signal head bracket 3 Aspect
667/2/30070/004 Signal head bracket 4 Aspect
Note that the above part numbers are only for the brackets themselves and do not include any additional fixings that should be supplied with the signal heads as standard.
10.2.2 Stainless Steel Mounting Brackets
For additional corrosion protection there are a range of Stainless Steel signal head brackets available for selection. These brackets carry additional cost but are manufactured from marine grade (316) stainless steel so offer outstanding corrosion resistance.
667/1/46165/002 Stainless Steel (316 grade) Signal bracket kit (2 Aspect)
667/1/46165/003 Stainless Steel (316 grade) Signal bracket kit (3 Aspect)
667/1/46165/004 Stainless Steel (316 grade) Signal bracket kit (4 Aspect)
Stainless steel can be easily identified on street as they have radii on all corners rather than the chamfered corners on standard steel brackets, see Figure 13.
Plastic brackets should not be used with Helios signals as our testing has indicated that whilst the brackets may appear to be strong enough when they are new, there is no evidence to suggest how well they will perform after prolonged UV exposure.
An additional concern is the manner in which they failed during our testing, shattering violently, which is not an acceptable method of failure.
Critically the brackets also show signs of creep over prolonged loading, as well as lower stiffness, meaning the signals will oscillate more during windy conditions causing increased stress to the enclosure.

Where signal heads are to be fitted at an angle of rotation greater than 45, and also need to be tilted, side mounting brackets (part no. 667/1/30200/058) should be installed as shown in Helios handbook 667/HB/30000/000.
10.4 Extension Brackets (D-Brackets)
Signal heads can be mounted away from the pole using extension brackets or ‘D-Brackets’. To ensure that the arms are mounted the correct way up, the mounting plate on the arm should be examined. It will be apparent that the lip is longer in one direction and the longer lip must be mounted toward the top of the pole.
Figure 15: Extension Brackets
Make up on the ground by laying out the two horizontal arms and attaching the vertical bar between them using the fixings provided.
Hang the extension bracket on the pole and fix using the nuts provided.
Add bolts and spacers to the extension bracket on which to hang the signal head. All bolts should be securely tightened.
Extension brackets must never be installed on passive pole installations, instead consider changing the pole and signal configurations to suit.
The following extension brackets should be used:
667/2/02442/300 EXTENSION BRACKET 300mm GALV
667/2/02442/600 EXTENSION BRACKET 600mm GALV
667/2/02442/900 EXTENSION BRACKET 900mm GALV (Check with Engineering before use)
Due to the increased torsional loading applied to poles with extension brackets fitted, ANY pole above 4.4m in height, in a country, or exposed location OR in Area 3 of the wind map, must be checked by Siemens Engineering before use.
10.5 WiMag brackets
WiMag extension bracket kits are suitable for mounting to any straight pole and they mount the repeater/access point at either 4,5 or 6m from ground level. Unless installed in a particularly exposed location, these kits can be fitted on any straight pole less than 4.4m in height without having to check with Engineering. Where installed on taller poles or in exposed locations, please contact Siemens Engineering for further guidance.
Other WiMag mounting kits for signal heads can be fitted to any pole combination.
10.6 Tunnel Hoods
Tunnel hoods generate increased torsional loading to the signal poles. Any pole with a door opening is weaker in torsion, therefore when using tunnel hoods on these poles, extra checks may be required. Refer to Appendix C for installation limitation requirements. If the pole configuration is very close to the maximum allowed configuration in that area then Siemens Engineering department must be consulted to allow further checks to be carried out.

All poles identified within this document have been subject to the appropriate independent structural assessment in compliance with the requirements of the Construction Products Regulations. The pole range has been designed to meet the great majority of site installation needs and therefore the requirement to use poles outside of the range will be rare.
However, where there is a perceived need to use poles outside this range Siemens staff must adhere to the following guidelines. It is preferable that any deviation from the standard pole range is identified early, preferably during the tendering stage of a project.
Consult the customer to define the reasons for not being able to use standard poles from our list. Where possible, Siemens Staff should always request designers and customers to select poles from the approved list. There will be a structural assessment and setup charge for ANY pole non-standard pole which will vary depending on the complexity of documentation and validation required.
Where there is a requirement to use non-standard poles, a justification should be presented to the Product Manager for initial approval, including the pole datasheets and foundation details of the poles required. Where the poles that have been requested are designed or manufactured by others, their CE documentation and drawings will also need to be supplied with the request.
When approved, the requirement will be sent to Engineering for consideration and estimation of setup costs.
Engineering will submit the cost estimate back to Product Management and Tendering for approval. Any product costs will have to be obtained by the relevant commodity manager.
Once approval has been gained from the customer a booking number must be assigned to Engineering to create new pole variants/types. A decision will be made at this stage whether or not the new poles are to be considered part of our standard pole range.
All CE documentation will be generated, part numbers assigned. Once all of the above has been completed, the pole(s) can be used against specified installation criteria.

Appendix A. Pole Number comparison tool There is a comparison tool available that defines the variations between old and new part numbers. This can be found in document 667/HB/52701/000.
The purpose of this tool is to allow you to find the nearest equivalent to any old Siemens part numbers you may have used in the past. By entering the old part number, the tool either specifies an exact equivalent or the closest variant in the new range. Where there is a variation in the closest version, a description of the variation is also given.
In addition to the closest variants, the tool also defines the most important data relating to the specified pole, such as structural strength, weight and suitable socket size etc.

Installation of the Water Resistant Enclosure
1. Remove the pole door using a standard 5mm A/F Allen key and place on the ground leaning against the pole. 2. Remove the enclosure from its packaging, open the unit with the Triangular “T” key (a quarter turn on the “Lock
Pin) and disassemble the unit. Figures 16 and 17 Important Note: - The “lock Pin” can be turned, a quarter, in either direction to open the enclosure.
3. Connect the earth lead as shown in Figure 17 and 18 4. Secure the back section, of the enclosure, into the pole using the 2 x M6 welded studs with the two pole mount
grommets, M6 nuts and washers, making sure the two pole mount grommets are fitted between the pole and back section of the enclosure. Figure 19 Important Note: - The open section of the enclosure is the top of the unit.
5. Connect the Earth lead provided from the termination plate “Earth Star Point” to the earth stud on the pole and to the pole door fixing studs. Important Note: - Make sure all earth connections are secure.
6. Secure the pre-made off signal cable/s, using the CET gland nuts and bolts, to the slots provided on the bottom of the termination plate. Figure 20 Important Note: -
a. When making off the signal cable/s ends it is important you install the armoured wire correctly and set the “Jubilee Clip/s” screw barrel in such a manor to prevent them from fouling against the pole.
b. When securing 2 x cable glands it is important to use the vertical slot on the left hand side with the gland to the top of the slot and the CET gland to the horizontal slot towards the centre of the terminal plate, to prevent the clips fouling on the inside of the pole.
7. Terminate the signal cable/s wiring to the right hand side of the terminal blocks making sure you form a drip loop and leave the vertical access slot (to the back of the terminal plate) free. Figure 21 and 24
8. Run the cables from the top of the pole (signal heads, solar cell, above ground detectors, etc) through the plastic stuffing glands into the termination plate. Ensure that the correct rubber gland inserts are selected to suit the cable diameters used. Figures 22 and 23. Add additional stuffing glands to knock-out points, as required. Important Note: - Leave a drip loop in the cable inside and outside of the enclosure.
