Cabinet safety through electronic locking and monitoring systems

17 November 2004 Manufacturing / Production Technology, Hardware & Services

EMKA has long been producing locking systems with mechanical locking parts. Today, the market requires more up-to-date safety and technology and EMKA has followed this demand by developing electronic locking systems combined with its module technology, to offer more safety and also the capability to unlock by remote control.

The recently-introduced ELM electronic locking system is a great aid to improved awareness of the environmental status of remote equipment, such as roadside cabinet installations. Increased amounts of equipment in these installations, such as larger processors or battery chargers, and the external climatic elements involved in world specifications, now give rise to major concerns over temperature and humidity control, as well as the access security of equipment. Since global equipment development today means coping with widely varying climatic conditions, the ELM system was designed to take care of all security issues, including internal thermal/humidity control, as well as cabinet integrity and entry control.

For indoor and outdoor applications some access methods are: electrical opening systems; standard transponder systems; networked transponder systems; keyboard systems; combined keypad/transponder systems; and cellular phone systems. For monitoring, the ELM sensor modules allow feedback into the main cabinet security system to give monitoring results and alarms. These may subsequently be fed to a GSM modem that transmits reports such as over/under temperature, increased/decreased humidity, excessive vibration, and door open/closed, etc, to remote stations.

The ELM system consists of different functional units connected via bus only. Up to 64 modules can be connected to the bus within a maximum 1 km length. The modules can have the same or different functions. A record of the last data status during a power shutdown is made inside the module and it is possible to run a software update or program the modules via the bus.

An ELM network is flexible in that it may also be interfaced to proprietary LAN systems and building control systems via a linked server, offering the ability for operators to monitor and control the equipment installation from anywhere in the world.

The Programme 3000 ELM system is designed to meet the needs of modern security systems both in terms of personnel access, control/logging procedures and to handle increasing needs for internal cabinet environmental monitoring/control.
