Is Tail Gating a problem for your business?

Clarke Instruments has recently installed another double stainless-steel turnstile in a south coast food manufacturer’s facility.

The customer relies heavily on agency workers to cover peak periods and holiday periods. Although they had access control equipment fitted for monitoring time and attendance and to provide an accurate record of site personnel at any one time, workers had started coming in in groups, one person swiping their card to release the entrance doors for all members of the group to walk through. This posed security and health and safety concerns.

The Company contacted us to discuss possible solutions. A telephone call lead to a site survey and it was decided to remove the entrance doors causing the problem and replace them with a double turnstile. Being a food facility, stainless steel was proposed and this recommendation was accepted by the company. Using their existing access control, the turnstile was configured one walkway for entry and one walk way for exit. In the event of fire or power failure both walkways would free wheel for exit. This was easily accomplished with our standard built in fire alarm relay and a spur from their access control linked to the standard in built auxiliary power supply.

An order was placed for us to supply and install on a strict time schedule of 6 weeks. Due to the limited size of the external entrance the turnstile was delivered in a flat pack format on the agreed date and was erected and commissioned on the same day.

We are immensely proud of our reputation of supplying robust reliable long-lived products at very realistic prices.

Scottish Bank Chooses Clarke Instruments to secure their Premises

A major Scottish Banking Group has turned to the Clarke instruments type 474 turnstile to secure their premises, enhancing control and monitoring of staff.

The 474 is a full height turnstile ideally suited to applications where a higher degree of security is needed. The full canopy design inhibits climbing. This is made even more difficult for would be intruders when installed flush in the fence line. If required rotor spikes can be added for additional security.

The turnstile comes with a fully integrated fire alarm relay as standard as well as an auxiliary power supply to drive any access control equipment required.

Normally supplied with a powder coated finish, we have seen increasing demand for stainless steel versions especially where environmental conditions are harsh or an aesthetically pleasing finish is required for an internal application. We at Clarke Instruments are committed to providing robust well engineered products that are both reliable and long lived and at realistic prices: a winning formula!

We are also able to offer a full maintenance package and a supply and install option if desired.

Major food preparation supplier chooses Clarke Instruments.

We at Clarke Instruments have been working with a major food preparation company based in the West Country. They decided to re-evaluate their perimeter security.

They were having tail gating problems and with their peak period, Christmas, looming and the consequent heavy reliance on temporary and agency staff they felt a need to do something to improve perimeter security.

After initial discussions and a site survey they decided on the ever popular and rugged 480A-209 double turnstile. This could be used effectively to establish tighter controls on entering and exiting the site. The turnstile which is bi-directional on both walkways in normal operation was ideal, given the volume of people entering and exiting. The Customer also took advantage of the built-in fire alarm relay and auxiliary power supply to power their own bio-metric controls.

As this is one of our most popular products we were able to supply from stock so from order to delivery and installation was complete in under 2 weeks.

Another satisfied customer and a promise to use us in future developments.

Clarke Instruments for the control of access

As a direct result of further enhancements, we have completed an order for four 493A-205 D/B Double Airlock Bi-Directional Turnstiles required by a major construction site services provider. These products have been developed and enhanced over many years as our business relationship with the construction industry has evolved and are fundamental to the control of access on many sites.

These state of the art turnstiles are available in single or double formats and can be supplied with integral tread plates, allowing easy relocation using Hi-ab or crane. They are also available on metal pallets, allowing easy relocation using fork lift trucks.

The product is exceedingly robust and is well suited to the construction industry environment. In consultation with the customer the access control has been developed to include facial recognition and numerical key pads working with activity logging software to provide accurate records of site attendance. The airlock feature makes it impossible for unauthorised people to enter the site. With separate tool box hatches, this turnstile is ideal for the construction industry. The roller shutter option allows the turnstile to be locked off securely when access to the site is not required. In case of fire the turnstile can be put into free wheel to allow rapid evacuation.

This long-term relationship has developed out of mutual trust and respect and we look forward to it continuing for many years to come.

If you need standard or client specific products let us help you provide the solution.

World renowned publisher chooses Clarke Instruments again

A world renowned publisher of newspapers has chosen us again following a review of security equipment

We have recently supplied and installed two replacement 474 turnstiles with hooped bar rotors to this prestigious customer on the outskirts of London at Broxbourne.

Although mechanically sound, despite heavy use and without regular servicing and preventive maintenance being undertaken, the original turnstiles were beginning to show their age and the decision was made to replace them.

Our customer contacted us and following consultations including a site visit, they eventually opted for an upgrade by having the replacement turnstiles pre-galvanised prior to powder coating to provide additional protection against the worst of the weather and the necessary salting of foot paths in icy weather in the winter months.

The whole process from initial enquiry to installation on site was completed within 14 weeks and is another example of how we work with our customers to provide a successful, practical and timely solution for their security requirements.

Fruit importer chooses Clarke Instruments

One of Europe’s largest fruit importers and distributors, based north of London, have chosen us to upgrade their site security


The company was looking for two levels of security.

The General access control for employees using the main entrance was catered for with two of our best selling 480B-200 fence line turnstiles. These allow quick easy access for staff with the appropriate authorisation while also enabling their location (on/off site) to be monitored at all times.





A higher level of security was needed for a second, more sensitive, site location that required staff to have a higher level of authorisation. For this access point our client chose the more secure and robust 474B-202 turnstile.



Commonality of parts across the Clarke Instruments Ltd range of turnstiles enabled the seamless integration of access control systems into the two types of turnstile, giving the company the necessary confidence and information required to know the whereabouts of staff and visitors.

Although security requirements prevent the use of some turnstiles as fire exits, fire security relays are fitted as standard in all other Clarke Instruments turnstiles. The 480B-200 and 474B-202 turnstiles supplied to the fruit importer have been programmed to go into a safe operating mode on fire alarm activation, assisting with the safe egress of all personnel from the buildings in case of fire.

Global health care company chooses Clarke Instruments

A health care company has chosen our products to help secure their premises on the outskirts of London.

After in-depth meetings to discuss and agree the design with our client, the products selected were two 480B-200 turnstiles with rain covers and one motorised gate.

The site has two entry points requiring control of access. One required a turnstile only while the other needed a turnstile and a full height automated gate to one side to facilitate disabled access.  Our customer also requested rain covers to be fitted over the turnstiles.

As this was a supply and installation contract our installation department liaised with the client project manager to ensure all necessary ground works were finished prior to the agreed dates for install. This enabled us to complete the site installation quickly and efficiently, to the satisfaction of all parties.

The control board supplied with our products enabled the existing access control equipment to be seamlessly integrated without incurring additional costs. Our built-in fire safety relay was linked in to our client’s safety systems.

The following week our client, who was project managing various works on site, wrote to us saying, “Thanks very much to you and your team for your help with the successful installation of the two turnstiles last week. Our client is very happy.”

Due to the success of this project we have been asked to submit quotes for similar work on other health care sites.

This again demonstrates our ability to design, manufacture and install tailored security solutions for clients in a timely and cost effective manner.

If you take security seriously, you will be delighted with our turnstiles and gates.
