Overview
The ATL-MN300 is a new type of analog fire alarm control panel which has 324 alarm control points (detectors and modules which are characterized by fully mixed coding, non-polarity and two buses). It complies with the provisions of both Fire Alarm Control Units (GB4717-2005) and Automatic Control System for Fire Protection (GB16806-2006).
Features
1 The intelligent detectors and the intelligent modules have internal microprocessors to realize digital filtering and auto-compensation functions; the data collection is true and reliable; the ATL-MN300 control panel can carry out data processing based on fuzzy control theory and modern fire alarm theory to fundamentally avoid missing alarms and to reduce false alarms, so as to improve reliability.
2 The detectors have a sensitivity setup function and can adjust the alarm sensitivity according to the specific environment and their influences.
3 The detecting bus and the control bus share a two-wire structure and have non-polarity and fully mixed coding of the detectors and modules, and the intelligent detectors and the intelligent modules can be directly connected to them, which greatly simplifies the system wiring, engineering installation and circuit maintenance.
4 The system uses an AC-DC master-standby power supply system which will automatically change between the master and standby power supplies in the event of a power failure of either of the two power supplies to ensure uninterrupted operation of the system.
5 The ATL-MN300 can be connected to a special mini-printer to realize real-time printing.
6 The ATL-MN300 can be connected to floor fire display panels to display fire alarms by standard RS-485
7 The ATL-MN300 can be connected to ten multi-line linkage control/monitoring points to control and monitor important equipment.
8 The ATL-MN300 is equipped with eight bus manual control points, which makes it very easy for the user to control related equipment.
