In this case the client was looking for static invertors which could also be used as a centralised testing solution.

Beghelli now offer a wide range of central battery systems, which can cope with any size of system, from one which is very small to one which is large, and which can be used to power any type of luminaries, making it an extremely versatile solution.

This is the ultimate way to limit the effects which emergency lighting has on the aesthetics of a building. Another benefit of a central battery system is that the batteries last much longer, and the process of replacement is far simpler and hassle free.
In many cases central battery systems are also used were it is necessary to achieve greater levels of luminance during an emergency, as you can achieve far better light output from one fitting run on a CBS compared when compared to the same fitting that has been converted for emergency use.

Liverpool Museum Trust looks after a variety of buildings from New Builds to those of a historical nature. Each building is open to the public and needs an emergency lighting system which does not detract from the aesthetics of the building, and which can be maintained easily without too much disruption. For this reason Logica FM was the ideal solution. The customer on this occasion chose to have each Museum run independently and installed a control unit, PC and software on each site.

This meant that testing of the emergency lighting could be set to happen at times that suited the museum, as well as making it possible to group the fittings so as to allow the testing of luminaries to be staggered, which consequently allows the Museum to remain open to the public at all times. The Client in this case also has many emergency conversion kits and fittings which are difficult to access, either because they are in a public gallery or because they are mounted high up on the ceiling or in voids, thus making remote testing all the more convenient.

In this example the client chose to use CTS and CTOC. CTS is a central battery complete with a monitoring and testing system, which allows the customer to use the mains lighting for emergency purposes in the areas or buildings were aesthetics are most important.

The testing and monitoring solution incorporated into this system enables the customer to comply with the British Standards in a much more cost effective way.  CTOC was used in all other areas of the 400 acre site which enabled them to have a centralised test and monitoring system for the rest of their emergency lighting.

The client in this case has the dilemma of looking after numerous buildings, some of which are halls of residence and therefore have students inhabiting the property most of the year round, thus making it extremely labor intensive, time consuming and costly to test all of the emergency lighting as per the British Standards.

By choosing to use Logica FM it has enabled the university to control their emergency lighting network remotely, and from one central place. The system does not limit the client to any number of devices, and it works as on a modular basis enabling them to add new fittings to the system when it suits.

Because a radio signal is used to carry the communication between each fitting, no additional communication cabling is required.  Emergency tests are triggered by timers, which can be set to meet the needs of the client, and test results are then stored on the system for a minimum of 2 years. Error reports provide a description of any faults such as lamp, battery, communication .The location of each fitting is shown on a CAD drawing which is loaded onto the PC and Logica Visual Software, enabling someone to know where to go, and what to take with them to fix the problem.

The Cowlairs project is an example of where Logica has been used to its full potential, with both the mains lighting and the emergency lighting being monitored and controlled from just one central point using a combination of Logica and Logica FM.

The mains lighting system incorporated both movement and daylight sensors as well as providing the customer with a facility to activate group lighting scenes using a preprogrammed timer.
The emergency lighting in this building is controlled by Logica FM, enabling all testing to be preprogrammed with test results feeding back to the control unit where the information is then stored for a minimum of 2 years.

All fittings both mains and emergency are given an address which then enables the location of each fitting to be shown on a CAD drawing facilitating fast fault recognition and diagnosis, as well as providing the maintenance team with the exact location of the fitting.

This system allows the client to benefit from low maintenance costs as well as ensuring that energy usage is reduced where possible.

On this project the client opted to use Auto Test fittings from the Beghelli range.
Auto-test is a simple but effective way of monitoring and testing the emergency lighting. A small LED emits a signal to the client allowing them to determine the operational mode of the fitting.
