1. PRESENTATION
An access site equipped with automatic retractable bollards generally consists of three main
components interconnected by electrical cables and a pneumatic or hydraulic flexible tube.
The 3 main components are:
Security loops (electro-magnetic detection): they are buried in the ground on either side of the
bollards and represent a security perimeter around them.
Automatic retractable bollards are installed on vehicular drive track; they authorize or forbid access
(one or several bollards per access site).
The management system (access controller) with built-in automation (CITY-type controller, technical
centre or armoured cabinet), to command the bollards. It can also comprise a control device (card
reader, radio receiver...)
To install security loops and management system (CITY controller, technical centre…) please, refer to
the corresponding manual. .
The positioning of security loops is a paramount condition for a good operationality of the access site.
We therefore strongly recommend prioritising the location of loops, then the position of bollards
and management system.
It is recommended to comply with the following to ensure good use of an access site
controlled by one or several automatic retractable bollards:
SECURITY RULES FOR A GOOD USE OF AN ACCESS SITE CONTROLLED BY
AUTOMATIC RETRACTABLE BOLLARD(S)
So as to ensure a good functioning of the access site and for safety reasons, URBACO recommends the
following:
- Place a vertical sign post showing «retractable bollard obstacle» ahead;
- Equip automatic systems with traffic lights warning of bollard status or position (red and
amber, blinking)
For access control systems, URBACO recommends that vehicles necessarily stop before the bollard
and wait until it is fully retracted (and respect the red turning to blinking amber if the access site is
equipped with traffic lights) before proceeding, make sure that it is retracted underground and
respect position light warning if there is one installed.
During the automatic rise of bollards once a vehicle has passed, other vehicles should by no means try
and drive one after the other through access without each stopping before the bollard.
INFORMATION AND EDUCATION OF USERS
The access operator must absolutely inform users how the system works and how properly to use it.
URBACO will not be held responsible in case of mishandling or security rules not being respected.

2. CIVIL ENGINEERING / ROADWORKS
To install the lost casing, refer to the embedding plan provided with each casing. This plan shows all
necessary indications and dimensions. The following paragraphs complete the indications and
dimensions provided in the embedding plan.
2.1. How to install and position the lost casing:
CAUTION! WHEN POSITIONING LOST CASING
MAKE SURE IT IS DIRECTED IN ACCORDANCE WITH TRAFFIC FLOW
The lost casing of Tradition-type bollards will be positioned so that the axis of side holes is at right
angles with traffic flow.
The lost casing of Generation 6 bollards will be positioned so that the axis of side holes is parallel to
traffic flow.
The embedding location chosen must be out of the usual driving track.
The recommended axis distance between two bollards side by side is 1.45 m.

Case Nr.1: Case of retractable bollards of the Generation 6 range
Case Nr.2: Case of retractable bollards of the Tradition range
The protecting conduit system for underground cables running from the bollard to the proximity
manhole (or directly to the management system) is a conduit such as JANOLENE Ø 100 mm
(www.janoplast.com) The trench dug for this conduit must be at least 100 mm away from any loop
cable. It should not be bent at an angle or abruptly curved (in case Nr.1, round the conduit (bending
radius 400 mm) just outside the bollard or place a L-shaped coupler.

URBACO – S.A.
URBACO - 6 -
2.2. Ground markings and excavation:
Once the location and positioning of lost casing
have been defined, trace the X and Y marks for the
hole to dig all by referring to dimensions specified
on the embedding plan provided with the lost
casing.
Then, depending on nature of soil, cut road coating
with miter saw or remove cobblestones.
When several bollards are side by side, we suggest
digging a trench rather than several holes in a row.
Dig as low as Z all by referring to the embedding
plan provided.
Then dig a trench all the way to the manhole or to
the management system all by referring to the
embedding plan provided.
2.3. How to drain:
Create a drain the size of which will depend on soil permeability (200 to 300 mm). Lay geotextile on the
lower part of the excavation, and then fill up with about 250 mm of ballast (pebbles). The installation
must be capable of draining 20 litres of water in 5 minutes.
If the soil is not permeable enough, it is recommended that the bottom part of the pit be connected to
local sewerage (PVC tubing diameter 100).

2.4. How to pour raft and install lost casing:
Gauging of cement to be used = 350 kg / m³ (3000 PSI)
Steel elements must be covered with at least 5 cm of concrete.
After reinforcement, pour foundation raft using level to make sure it is perfectly plane and horizontal. Do
not forget to protect the drainage pipe (PVC Ø 100 tubing) connecting the bottom part of the lost casing
to the drain. It is of paramount importance that dimensions mentioned on the embedding plan be
respected.
Each time concrete is poured, this should be done using appropriate internal concrete vibrators for
compaction. Foundation raft will be as thick as indicated on the embedding plan.
2.5. Embedding of lost casing:
- Place the lost casing on foundation raft making sure it is well positioned (see §1.1 to 1.4).
- Take the end of the conduit though one of the 2 side holes on the lost casing (see embedding plan) and
let it stick out by a few centimetres inside. Block the side hole which is not used.
TO BETTER RESIST CONCRETE PRESSURE AND TO PRESERVE DIMENSIONS, PROP
UP THE INSIDE OF LOST CASING WITH SPACERS.
- Before and after pouring concrete, check that the lost casing is perfectly levelled, vertically and
horizontally, and that dimensions are respected so as to ensure it will lodge the bollard easily and
without any problem (the top edge of the lost casing should be below finished surface level; see distance
indicated on embedding plan provided with this manual).
Delicately pour concrete around the lost casing. The vertical walls of concrete will be at least 150 mm
thick. Let it set and check level.
2.6. How to check that lost casing will suitably lodge the bollard casing:
Control the lost casing width from bottom to top. It must be identical to that indicated on the embedding
plan. Make sure there is no empty gap underneath the lost casing.
Ensure that the drain is properly working (able to drain 20 litres in 5 minutes or 4 litres per minute)
Check that the lost casing is clean inside. There should be no concrete running inside to ensure that the
bollard casing will be properly positioned on the bottom of the lost casing.
Control the depth of the lost casing. It must be identical to dimensions indicated on embedding plan.
If the lost casing is embedded too deep, bedding on foundation raft is cancelled and the bollard casing
just hangs from the cover’s edge. This is definitely something to avoid by all means.
If the lost casing is embedded too high, the whole bollard set will protrude like an obstacle, dangerous for
pedestrians. Resurfacing to conceal step remains hazardous. This is also something to proscribe.
Clean around jobsite (sand, gravel, etc) anything which can damage the coating on bollards.

URBACO – S.A.
URBACO - 8 -
2.7. How to draw cables and flexible tube inside conduit:
Between each bollard and the management system, there must be:
Pneumatic installations:
• 1 flexible air tube Ø10, length = 25m. This flexible air tube must not be cut or shortened. The
excess length will be used as air reserve, coiled and lodged inside manhole where cables are
drawn from.
• 1 multi-conductor cable for connecting solenoid valve and limit switches.
Hydraulic installations:
• 1 hydraulic flexible tube with couplings; No standard length supplied, depending on site
configuration and what has been ordered. Caution! The female section of the hydraulic tube must
be directed towards the bollard.
• 1 multi-conductor cable for connecting limit switches.
Note: Protect end sections of flexible tube prior to drawing cables to avoid intrusion of dirt.
Each option (heater, LED ring) will require its own cable.
When cables and flexible tubes are drawn, push them back temporarily inside conduit so that
nothing sticks out while the bollard is being positioned inside the lost casing.

3. UNPACKING AND POSITIONING OF BOLLARD
3.1. Unpacking (casing and bollard):
Precautions to be taken before unpacking:
BEFORE CUTTING TIES MAINTAINING YOUR CONSIGNMENT, CHECK THAT THE BOLLARD IS
STABLE AND CORRECTLY POSITIONNED ON ITS PALLET; ALSO CHECK THAT THE PALLET IS IN
GOOD STATE, taking into account the important weight of bollard.
Each bollard is taped at the top and at the bottom in yellow; it reads in 5 languages: «Do not remove
plastic film».
IT IS IMPERATIVE TO LEAVE THE WRAPPING PLASTIC FILM AROUND THE CASING to be able
later to spray polyurethane foam between the bollard casing and the lost casing. It prevents foam from
penetrating inside the casing.
Remove plastic cap from cover with a screw driver (only for bollards of the Tradition range), then
unscrew the 4 bolts and put the cover on the side. Remember position (direction) of cover on casing to
be able to put it back exactly the same way afterwards. Controls that the cylinder (jack) and the cross
hitch are well positioned at the bottom of the casing.
To unpack, cut the plastic at the top right
underneath cover. Remove key placed on
cover and keep it for later use.
Likewise, cut plastic film underneath the
casing to later enable water drainage. To do
so, have someone assistant by maintaining
the casing
inclined on one side, then on the
opposite side.

3.2. Positioning (casing and bollard):
PRECAUTIONS BEFORE POSITIONING BOLLARD
Due to its weight (up to 200 kg) and crushing hazards while the bollard is being positioned inside the lost
casing, foremen in charge of this task must pay special attention to the following procedures and respect
protection and security of personnel (security shoes for instance). Jobsite should be closed to traffic with
the appropriate sign posts for this type of road works. Securing the jobsite is to be done right at the
beginning of civil engineering road works.
The bollard will be positioned using the appropriate lifting appliances such as (wrecking crane or hoist)
with a force superior to 500 kg.
Replace 2 of the cover screws (diametrically opposite) by lifting rings, 12 mm in diameter, with lock-nuts,
to be bolted in lieu and place of the cover screws. Slinging is to be done with appropriate means.
Position the bollard casing inside the lost casing:
Lower the bollard inside the lost casing. Make sure it is in accordance with traffic flow.
Check that everything is lined up, vertical. Freeze the casing to a standstill by spraying
polyurethane foam in each corner. Once dry, cut or saw the excess polyurethane foam.

4. CONNECTIONS INSIDE THE BOLLARDS
4.1. How to connect a pneumatic bollard:
• Connecting the air circuit:
Connect the air flexible still in the conduit to the bollard with couplers supplied.
• Electrical wiring:
Take the cable from its conduit and the bollard cables.
Coming from the bollard are the following:
1 x 3-conductor cable marked EV – This is for the solenoid valve.
1 x 2-conductor cable marked FdCB– This is for the lower limit switch.
1 x 2-conductor cable marked FdCH– This is for the upper limit switch.
Junction of each conductor must be done using soldering.
Each soldered joint must be protected by a heat-shrink sleeve (not supplied). Everything must be
made watertight using waterproof heat-shrink sleeve (not supplied).
1) Slip a waterproof heat-shrink sleeve (not supplied) on the cable in the conduit.
2) Slip a heat-shrink sleeve (not supplied) on each conductor of this cable.
3) Strip the ends of each conductor.
4) Solder and mark out the conductors used (for connections inside the technical centre) as described
below.
Polarity is not important for either the solenoid valve or the limit switches.
When one bollard only is connected to the technical centre, common earthing will be done between
limit switches (use of 5 conductors). Otherwise, connect as shown below to be able to cable the upper
limit switches in series and the lower limit switches in series in the technical centre.
5) Electrically insulate by sliding each section of sleeve on each soldered joint and heat-shrink.
6) Ensure water-tightness of the installation by sliding waterproof heat-shrink sleeve and heat.
Do not entirely remove cables (from the other end of the conduit) but keep at least a 50 cm margin
on each side for any potential intervention such as the changing of the solenoid valve. Place the
excess length of cable inside the conduit, inside the manhole or fix it with clamp collars on the casing
walls making sure it will not hinder bollard motivity.
Before screwing the cover back on casing, make sure that the bollard movements will not be hindered
by a cable or a flexible tube being caught.

Junction of each conductor must be done using soldering.
Each soldered joint must be protected by a heat-shrink sleeve (not supplied). Everything must be
made watertight using waterproof heat-shrink sleeve (not supplied).
1) Slip a waterproof heat-shrink sleeve (not supplied) on the cable in the conduit.
2) Slip a heat-shrink sleeve (not supplied) on each conductor of this cable.
3) Strip the ends of each conductor.
4) Solder and mark out the conductors used (for connections inside the technical centre) as described
below.
Polarity is not important for the limit switches.
5) Electrically insulate by sliding each section of sleeve on each soldered joint and heat-shrink.
6) Ensure water-tightness of the installation by sliding waterproof heat-shrink sleeve and heat.
Do not entirely remove cables (from the other end of the conduit) but keep at least a 50 cm margin
on each side for any potential intervention such as the changing of the solenoid valve. Place the
excess length of cable inside the conduit, inside the manhole or fix it with clamp collars on the casing
walls making sure it will not hinder bollard motivity.
Before screwing the cover back on casing, make sure that the bollard movements will not be hindered
by a cable or a flexible tube being caught.

4.3. Finishing:
Proceed with control operations as described in details in the control operation §.
Position cover back onto casing exactly like it was before being removed (direction of traffic flow).
Screw the 4 bolts back and cover with plastic protective caps (only for bollards of the Tradition range).
Proceed with jobsite resurfacing to preserve nature of surrounding (tarred, red asphalt, cobblestoned
area, etc.)
4.4. Connecting the technical centre:
Refer to the manual for the installation of an automated system and the technical data sheet supplied
with system.

6. HOW TO REMOVE BOLLARD OUT OF CASING
PRECAUTIONS BEFORE REMOVING BOLLARD
Due to the weight of the bollard (up to 100 kg), foremen in charge of this task are requested to pay
special attention to the following procedures and respect protection and security of personnel
(security shoes for instance). Jobsite should be closed to traffic with the appropriate sign posts for this
type of road works.
To remove the bollard head from the casing, proceed as follows:
• Set the bollard in the upward position,
• Remove cover and put it aside,
• Using a robot grip tool such or similar, extract bollard head,
• Switch power off in the technical centre,
• Proceed with maintenance operations as described in the following paragraphs,
• Likewise, put the bollard back into the casing and check that the pneumatic cylinder is well
positioned on the crosspiece,
• Put the bollard in its retracted position,
• Put the cover back on top.

7. CONTROL OPERATIONS (to be done also commissioning)
7.1. Cover fixings:
Fixing bolts must be removed and threading in casing cleaned, then greased with Molykote Cu-7439
copper paste or similar.
Generation 6 : Tradition :
7.2. Anti-friction plastic ring:
The anti-friction plastic ring is a wearing part which is intended to reduce friction between the bollard and
the cover. It should be replaced if the bollard has been violently impacted or when the wearing state so
requires.
Remove the old plastic ring with a screw driver. Once glue residuals have been scratched off, insert new
plastic ring and fix it with polyurethane glue.
- on flat covers of bollards Ø120mm, the two ring lugs are hooked in their respective notches.
- on flat covers of bollards Ø200mm and Ø250mm, there is no specific way how the plastic ring should
be placed.
- on tilted covers (Ø120mm only), there is no lug or specific way how the plastic ring should be placed.

Ensure that the cylinder clevis is correctly positioned between both lugs on the crosspiece at the bottom
of the casing.
Pneumatic Monobloc range:
1– Tip of the cylinder rod
2– Centring guide
3– Flange
4– Tie-rod (with threaded ends and bolts to maintain
both flanges against the cylinder shaft)
5– Cylinder shaft
6– Crosspiece is one with the casing and supports
the cylinder (the threaded ends or the 4 tie-rods
ensure centring at the base)
7– Coupler for air flexible inlet.
Make sure that the lower flange of the cylinder is correctly positioned between both lugs on the
crosspiece at the bottom of the casing and that threaded ends of tie-rods are well lodged on either side
of the crosspiece.

7.5. Limit switches:
The bollard is equipped with two limit switches (lower and upper).
Each sensor informs the management system PLC of the position (status) of the bollard head, thus
taking part in the access securitisation. Contact of limit switches is of the NO (normally open) type.
The casing bears the sensors on their mounting lugs.
The magnetic detector is mounted on a lug in the bollard head or on the carriage (Tradition).
Check that each limit switch sensor is properly mounted and positioned: It should never be in contact
with the magnet.
Check that magnet ensures good detection when bollard head is up or down.
In case of a malfunction, check connections on the connection rack in the management system,
connections of the bollard and if the problem is not solved, replace sensor (see §3).
1– Limit switch sensor on
its lug as mounted on
casing (at the top and at
the bottom).
2– Magnet in its protective
lug as mounted on the
bollard head.
7.6. Air distribution (for pneumatic installations):
The air distribution consists of a solenoid valve (body and coil), an airflow regulator, a set of couplers
and flexible air tube.
Reminder: the airflow regulator makes it possible to adjust the speed at which the bollard will rise, just by
turning the spanner one way or the other way round. The bollard should rise in no less or no more than 3
seconds. It is not advisable to let it rise too quickly or too slowly!
1– Solenoid valve (body)
2– Solenoid valve (coil)
3– Airflow regulator
4– Set of couplers (elbow
union)
5 – Flexible air tube
NB: Test couplers in case
of air leak.

Ensure that the airflow regulator is properly adjusted and that it lets the air flow in without
obstruction. Control fixing screws and how tight the lock-nut is adjusted.
7.7. Control and inspection of air circuit (for pneumatic installations):
Check that the compressor is functioning in the technical centre. The manometer should read a pressure
level between 4 and 6 bars. Recommended pressure on duty is 5.5 bar.
Control by ear or with your finger that no air is leaking from the flexible air tube or from couplers. You
may also want to use a leak detection spray (liquid sprayed will foam where there is a leak).
7.8. Control and inspection of oil circuit (for hydraulic installations):
Visually control there is no oil leaking inside the casing.
Control that the tubing is well maintained along the casing.
Control union of couplers.
7.9. Drainage efficiency:
The drain must be capable of absorbing 20 litres of water in 5 minutes.
Test as follows:
- Put cover on side and check that there is no sand, soil or any other foreign body or deposit. If so,
remove whatever fell in.
- Pour 20 litres of water in the casing and make sure water evacuates perfectly (this may take up to 5
minutes).
If the drain doesn’t prove efficient enough according to your criteria, use a water vacuum cleaner and
clean the drain conduit, several times on end if necessary, until drainage is perfectly normal.
7.10. Positioning the cover:
The cover must be placed in its initial position to ensure that the bollard will be guided inside the casing
with an evenly distributed play. Tightening of bolts must be done with a wheel-brace, ending with a
strong jolt (like when you change the wheel of your car). Cover the bolts with the plastic caps using a
mallet (Tradition bollard).
