Alarms in commercial buildings must be especially efficient and economical useful. Planners, installers and operators expect alarming strategies, with which they can react individually to structural requirements.
The base for a reliable alarm is a long-lasting, uninterrupted and distinct signal for a sufficient time. To support this base, many national rules and norms require an alarm signal interruption freedom for a period of 30 min (MLAR). The alarm concepts of the system detect 3000 from JOB Detectomat are based on these principles and integrate well pioneering technology providing a secure and convenient alerts.
There are several opportunities for an efficient alarming strategy . The choice of the presented concepts is dependend of the specific requirements of the project and the demands of architects, designers and fire services.
The proven stub technology offers significant advantages:
For further optimization of the cabelling, it is possible, to use a second pair of wires in the same cable for the alarm lines.
In buildings with many of fi re compartments, an optimal alarm can be achieved in the individual sections by the distribution of externally supplied energy. This can be achieved via control modules which include a power supply. Advantages of this alarming solution:
The Loop-controlled alarm via the signalling device family CONUS is fully performed over the Loop line. In this case the Loop cable is used for the detection and alarm.
The technical features and the unique emission characteristic of:
With the version 3.2 of the fire detection panel generation of dc3500 JOB Detectomat provides additional features for the Loop-controlled alarm functions inside the system:
The further development of the alarming concept that will be used with version 3.3 of the dc3500 is an improved Loop-controlled signalling device. This concept will make it possible to connect up to 126 different devices of the CONUS family on the Loop and to supply them with energy.
In addition to the acoustic and optical / acoustic CONUS devices then this series will be additionally available to realize voice alarming.
Via the dc3500 the CONUS devices can be controlled timely staggered and different sound and speech signals can be selected. This gives you the option for an individual adaptation to the respective alarm application.
More alarm solutions, such as the transmission to paging systems, the interaction with voice alarm systems (VAS) and the connection to telephone systems are ensured via the interfaces of the fire control panel dc3500.
