New CAT-5-connected call station

Bosch Security Systems is enhancing its acclaimed Praesideo Public Address and Emergency Evacuation System with a new Remote Call Station and Call Station Interface that use CAT-5 (Category 5) cabling.

The use of CAT-5 cabling, the industry standard for data communications in computer and IP networks, gives the Praesideo system even more flexibility in system design. The new Remote Call Stations can be located up to one kilometre away from the Call Station Interface. Other advantages of using CAT-5 cabling are that it does not add to the Praesideo's system bus length and it makes call station installation easier.

The new Remote Call Station - the LBB4438/00 - can be powered either by the Call Station Interface or from a local power supply if a large number of keypads are to be used at long distance. The LBB4438/00 can be extended with up to 16 keypads each with eight configurable keys. The Call Station Interface is also new and is specially designed to accept the CAT-5 digital audio and control data connection with the Remote Call Station, and to connect to the Praesideo's optical fibre network. Both the LBB4438/00 Remote Call Station and the LBB4437/00 Call Station Interface are fully supervised and comply with IEC60849, the European standard for voice alarm systems. A new Remote Call Station Kit - the LBB4439/00 - will also become available.
