Sentara – the new emergency lighting concept
Emergency lighting redefined:
flexible, mobile, easy to use.
Introducing our new emergency lighting concept – Sentara.
With this optimised system for controlling, monitoring and
supplying escape route and exit sign luminaires, we are now
able to fulfil many of the previously unattainable wishes of
planners, technicians and users. Our total solution concept
encompasses decentralisation with simple installation, easy
extension options and greater freedom of handling and assembly. We believe this powerful combination from Sentara
reflects an entirely new direction in innovative research and
development thinking and sets new and exceptional standards
in technical achievement.
2
Sentara is both in response to revised standards and recognition of the need for greater awareness in fire protection methodologies. In particular, the present state construction regulations, the model directive on cabling installation (MLAR) and
EN 50171 (central power supply systems) all insist on solutions
comprising a decentralised central power supply incorporating integral components. Our concept is in full compliance
with these recommendations and expectations.
Our solution consists of four main components, with specially
developed hardware and software elements. In addition, less
E30 installation material and junction boxes are needed in circuit integrity. So the system delivers substantial savings.

One Safe Solution.
Four versatile modules.

Sentara US
Sentara LBS
Independent substation modules
Intelligent luminaire modules
Our Sentara US microprocessor-controlled substations form
the interface between the control centre – Sentara CPS – and
the luminaires.
The Sentara LBS compact luminaire modules monitor and control the escape route and exit sign luminaires. The luminaires
constantly exchange information with their Sentara US substation via their supply cable.
The substations will immediately switch on the escape route
and exit sign luminaires within their compartment in the event
of a break or power failure. They also save all luminaire data,
which is then sent direct to the central system. Our Sentara mobile communication unit can be directly connected for
substation and system operation. If planning is based on a
fire compartment model when designing a building, this will
reduce the work needed to define, count and equip the fire
compartment with emergency lighting, which can be up to
1600 m2 in size. The location for the distributor housing is
flexible as no electrical operating room is required in the fire
compartment.
In this way, the Sentara US can keep track of the state of the
luminaires and the supply voltage. The system will recognise
any deviation and react to any faults occurring within a fraction of a second. All modules and luminaires are marked with
a bar code, which enables the unique addresses of each of
the lamps to be identified both quickly and easily. When put
into operation for the first time, the substations will automatically find and recognise all the luminaire modules on their
network and register them within the system.

Sentara CPS
Mobile communication unit
The control unit with a central battery
Sentara mobile is the entire system‘s operation and switching
centre.
Sentara CPS is where all the relevant system parameters are
recorded and prepared for data output to the mobile communication unit. It also keeps the battery constantly charged
so that, in a crisis, switchover to the emergency power source
to directly supply the escape route and exit sign luminaires is
ensured. Alternatively, the emergency power source can supply the luminaires using static or rotary converters.
The mobile communication unit enables technicians and endusers to input and extract data and system parameters from
any location, in addition to programming and controlling the
operation modes of all the luminaires. The mobile terminal
can be docked onto various points of the communication
system, connected via bus lines between the central system
and substations. The bus structure is completely flexible and
offers planners space for all conceivable solutions.

Maintenance cost reduction via prescheduled light source replacement
Every Sentara US substation automatically registers whether a single luminaire

connected to it is switched on or not. An operating counter measures the

in an awkward position fails. In this case, the knowledge of a luminaire’s
life, an operating or comparison value can be entered for each individual
