Fire Detection Control FMZ 4100
The Minimax fire detection control FMZ 4100 is a compact function centre with high availability, combining all the advantages of modern micro-electronics. The reliable and reasonably priced line technology is ideal for the monitoring of large areas. In addition, digital information can be transferred from each detector thus enabling, amongst other things, individual single alarm identification. As a result of this, it is possible to combine many small areas or rooms in only one detector group. The activated detector can then be clearly identified on the LC display of the fire detection control . The heart of the control is a micro processor controlled analysis unit. This unit is responsible for all monitoring and control functions and because of its inbuilt automatic interrupt control function it can react to alarm signals without delay. The itself is monitored by a watchdog timer which is reactivated each time data es through the cyclic running programme. If the trigger impulse fails to
appear, the programme controlled alarm analysis is interrupted in order to avoid any faulty functioning. In this case, the alarm evaluation continues to function by means of an emergency operational circuit. In the case of interference, maximum only one plug-in unit will fail to function due to the parallel operation of the different analysis units. It is also possible to exchange defective components without any operational interruptions occuring. The fire detection control FMZ 4100 contains all of the essential performance features of the earlier Minimax devices. Additionally, it fulfills all requirements of a modern comprehensive safety-information system with an integrated detector identification system and a large LC display as well as having a report printer, status and intervention system and an interface to building stration systems. These features enable an exact evaluation of the incoming alarms so that preventative measures may be carried out quickly.
Minimax's experience collected over many years in the field of evaluation and assessment of fire characteristics is to be found in an extensive, error-tolerant analysis software. The software enables the system to differentiate between alarm signals and spurious ( parasitic) signals. By means of a dialogue between the fire detection control and himself, the is led through the necessary operational phases thereby ruling out, to the greatest possible extent, all possibility of problems arising from incorrect operating or stress influenced abnormal behaviour in the case of alarms or disturbances. The fire detection control FMZ 4100 fulfills the highest safety requirements which are, of course, indispensable in the field of fire protection. The control including the system's components are in accordance with the valid guidelines, norms and regulations – especially VDE and EN 54 – and is approved by the ”Verband der Schadenversicherer“ (VdS, Association of German Property Insurers).
Design variants The fire detection control is a modular extendable 19" unit assembly system. Even in its smallest basic design (GAB 32), it is capable of accomodating 2 x 32 fire alarm groups and 32 primary control groups, besides the central equipment such as the power supply unit, battery and main alarm tripping. In the larger model (GAB 128), the system can be extended to 3 x 128 groups by means of additional plug-in zone modules. In this case, a common central plug-in unit (master system) takes over the overriding control procedure for the otherwise autarkic plug-in zone modules (master-slave process). A total combination of 3072 groups can be obtained by ing together up to 8 standing cabinets of the above type.
FMZ 4100 - GAB 32 is extendable, with each device having 32 automatic and giving fire alarm groups as well as primary control groups for the electrical monitoring and for the operating of the important function alarm devices such as alarm horns, release solenoids, etc.

FMZ 4100 - GAB 128 is extendable, with each device having 128 automatic and giving fire alarm zones as well as primary control groups. Upright cabinet 31U
Each group is connected to the line card via line termination cards. Using one line card, it is possible to supply, evaluate and monitor 4 alarm groups for automatic fire alarms, 4 alarm groups for giving fire alarms and 4 primary control groups. A reduced version can be supplied when only 4 automatic fire alarm groups are required. The alarm signals recorded in the fire control are digitalized and are then, in comparison between normal condition and actual condition, compared with the programmed values in the non-volatile memory. In the case of negative results, either an alarm signal or an interference signal (e.g. ”wire breakage“, ”short circuit“, ”detector removed“) is produced. A redundant, independent alarm circuit continues to conduct the alarm even in the case of interference or breakdown of the control system. Important alarm devices are connected to the quiescent current monitoring of the primary control groups.
Detector identification system (ZID-V) This is a system component which functions independently from the analysis unit. It displays selectively the position and type of the activated, defective or removed detectors. The main component of this device is a microcontroller which additionally and unidirectionally requests data from the detector via a secondary network. A specially developed analysis software checks the detector’s signal for accuracy and then evaluates it. The obtained results are transmitted asynchronously to the analysis unit via FIFO-circuits where they are then displayed on a comprehensive 8 x 40 figure alpha-numerical LC display. The detector identification system, the alpha-numerical clear text display and the report printer complement each other and together form an important information system thus enabling the quick introduction of decisive and appropriate measures.
Extinguishing control for the fire extinguishing system The system component ”extinguishing control“ is used to control single and multi-
Alarm and graphics reporting system
zone fire extinguishing systems. It functions independently from the other systems of the fire detection control and therefore has its own display and operating . Each extinguishing zone is controlled and monitored by an autarkical functioning extinguishing control card. All the important components which are necessary for the trouble-free functioning of an extinguishing system (e.g. detectors, release and alarm) devices are connected to the extinguishing control system. In the case of alarm, the extinguishing control system s and analyses the detector signal, sounds the fire alarm and activates the pre-programmed control function as well as the fire extinguishing system.
Programming The fire detection control FMZ 4100 can be programmed for different applications. For this purpose a special configuration programme has been developed which transforms the physical values of entered characteristics (e.g. alarm threshold, short circuit threshold, etc.) into a ”language“ understandable for the microcontroller. In this way, the has the maximum amount of flexibility which, for instance, is required when extending already existing systems. Programming is greatly simplified by the use of modern ”pull-down-menu-techniques“ and easy-to-understand input instructions.
Secondary groups The fire detection control FMZ 4100 can be equipped with free programmable relays in order to enable further alarm organization, for example: the disconnection of the air conditioning, the interruption of the manufacturing process, the opening of smoke vent flaps, etc. 2 break s (b-s) and 2 make s (a-s) with a maximum load of 2 amperes are available for each relay. The operating and logical combination of the relays is determined for each specific system by means of the Minimax configuration programme. The standard functions are as follows: operating tripped by alarm, pre-alarm and interferences as well as the disconnection of fire detector groups.
ZID-V detector
Serial interfaces The fire detection control FMZ 4100 has standard serial interfaces for connection to external equipment, e.g. alarm and graphics reporting system or printer, as well as enabling communication with a superordinate istration system. An additional microcontroller circuit which has been especially developed for the operating of repeater s as well as externally situated control devices can exchange information with the fire detection control via a serial interface. There are 768 programmable outputs available for the operating of the LEDs in a repeater . Additionally, the microcontroller has a serial interface for data transmission, e.g. for a desk-top printer. The fire detection control FMZ 4100 offers further interfaces for fire brigade control s as well as for the so-called ”public main alarm“. An alarm signal can be automatically transmitted further to an external service, e.g. fire brigade, by means of the main alarm function. Additional VdS standard interfaces are available for the connection of fire detection equipment from other manufacturers to the FMZ 4100 extinguishing control system.
Special applications Spark extinguishing systems The possibility of realizing special applications of fire detection and extinguishing technology were taken into consideration during the development of the fire detection control FMZ 4100. These special applications are, for example, spark extinguishing systems for the wood industry, fire suppression systems for paint spraying plants as well as for the protection of equipment in computing centres. If one takes the spark extinguishing system as an example, it can be seen that this system can be connected to the control without any special or additional analyzing electronics. All the requirements necessary for operating a spark extinguishing system such as adjustable extinguishing times for each extinguishing area, monitoring of the extinguishing agent supply, electrical monitoring of heat tapes and leak detectors are to be found in the standard programme of the control . It is, therefore, guaranteed that the evaluation of spark alarms as well as the operating of the automatic extinguishing system will be carried out with virtually no delay. Gas detectors A gas detector is an autonomous subsystem that can be easily integrated in the FMZ 4100 fire detection control . Owing to the increasingly complex chemical processes used in industry, gas detection at an early stage is often the main element of a safety scheme and is accordingly very suitable for combination with fire detection and fire systems. A display continuously indicates the gas concentrations in the gas detectors. If the gas concentration measured exceeds a preset limit, external equipment can be activated via secondary control lines. All measured data is ed on to the FMZ 4100 where it is recorded. This assures the traceability of events even after a lengthy period.
