Introduction:

Lenel brand  is owned by UTC Fire & Security Products offering innovative electronic security solutions for technical protection of buildings, industrial installation, military and other construction facilities. UTC Fire & Security has in it’s offer solutions to: Fire alarm system, intruder and burglary alarm system, access control and video surveillance.

Strength of Lenel’s brand is global web of authorized partners, known as VARs (Value Added Resellers). Employees of these companies take part in multi-stage trainings and constantly develop their qualifications. Now the VAR web counts more than a 800 companies, of which around 200 is located in Europe and only 5 of them in Poland.

KARO Karlicki Sp. z o.o. company is certified installer of Lenel OnGuard and distributor of Lenel’s devices, type VAR.

Thanks to so extensive web of VAR’s, the Lenel system is under the warranty service and technical emergency support. It creates favorable operating conditions for final user.

Software:

The hart of all Lenel’s system is server with OnGuard software.

The software contains modules performing various functions. It is an economical solution, as user choose only those modules, that are necessary. The server uses a database (Microsoft SQL or Oracle) in which information on user permission and working of particular system modules are stored.

To create the Lenel system expansion possibilities, OnGuard software contains a set of standard program interfaces (APIs) along with documentation, allowing to create software connections with third-party devices and applications. An example of such devices can be fire, alarm and building automation control panels, while the example of the application can be work time and attendance systems.

Equipment:

In general Lenel is an access control system, however thanks to the alarm and video modules, it can perform as intruder alarm system and video surveillance system. In a hardware part it uses intelligent, network system controllers (ISC – Intelligent System Controller), door modules (DRI– Dual Reader Interface or SRI – Single Reader Interface) and alarm modules (ICM – Input Control Module, or OCM – Output Control Module).

Server data regarding user privileges are transferred by IP network to intelligent system controllers and stored there. This allows to keep continuity of system operation even in case of IP network breakdown. The decisions on opening or closing doors are made in local intelligent system controllers. All occurring events are saved in controller’s memories and transferred to the server via IP network.

Mobile options:

Readers used in Lenel system enable implementation so-called mobile options allowing to use smartphones in place of identification cards. Beyond the obvious advantage of using only one device access to many different buildings, mobile option helps with authorization, administration and management of the system security level.

Data encryption:

In Lenel systems all data transmitted between identification cards and readers, and also between readers and drivers are encrypted. Open Supervised Device Protocol (OSDP) is used, which provides continuous readers status monitoring. Readers errors, damage and acts of sabotage are immediately signaled. All signals necessary for the operation of readers can be transmitted via a two-wire line, which reduces installation costs as compared to the Wiegand interface. Encryption has a fundamental impact on the level of system security, because the interception of transmitted data will not lead to anything.

Distributed Architecture:

In Lenel systems distributed architecture is preferred, it means that it is recommended that both intelligent system controllers and interfaces that are controlling the doors should be installed in a short distance from the controlled passage. This simplifies wiring of door accessories and improves the reliability of the system. Each of the intelligent system controllers has a connection to the server (so-called upstream) via the IP network. In turn, door and alarm modules are connected to intelligent system controllers via serial buses (so-called downstream), although here network connection can be also used.

Thanks to such architecture, the system gains reliability because possible failures cause that only a small part of the system does not work, the other elements are functioning normally.

Client stations:

Client software of Lenel system OnGuard may be installed on “thin client” working stations. Control over the system is also possible with use of standard web browsers.

System administrators and operators can configure the system via client stations, they can also respond to alarm situations, and view images from the integrated video surveillance system, e.g. TruVision.

Summary:

The popularity of the Lenel system results from its high functionality and reliability of operation. OnGuard’s modular software and distributed hardware architecture allows to create systems that are strictly adapted to local usage requirements. The extensive VAR network creates a comfortable operating environment for customers, as reactions to possible failures are very fast.

The Lenel system is particularly valued by corporations and institutions using many buildings or facilities, located at a considerable distance from each other. The network structure of the system allows to create of a central user database, which allows to administrate of ID cards within the entire company.

KARO Karlicki Sp. z o.o. company offers its assistance at every stage of the implementation of the Lenel Access Control System, starting from the initial analysis of the situation, through the creation of concepts, the design stage, the equipment completion, installation and commissioning, as well as maintenance service. We make cost estimates for the needs of budget calculations.

We also undertake the maintenance of existing systems.

Our employees are well trained, they have proper knowledge, experience and required permissions.

We invite you to cooperation.
