Any burglar alarm, intrusion detection and access control systems (ACS) due to extensive connections between the control panel and all kinds of sensors or detectors, are particularly vulnerable to various kinds of overvoltages, in particular - to atmospheric overvoltages (due to lightning strikes). Protection of such installations is particularly important at sites of special purpose, or non-supervised sites.
We offer you the complete solution for a comprehensive protection against overvoltages of the central alarm system. Protection is selected in accordance with the technical requirements of the system and the requirements of regulatory documents.
Advantages of our solution
- harmonized integrated concept of protection of all elements;
- improved reliability;
- reduction of the number of false responses (alarms);
- uninterrupted operation of IT-systems and safety equipment;
- MP series protection modules can be removed and replaced without interfering into the system operation;
- there is also a version for two pairs of wires (2DA) with four signal lines;
- Space saving in the switchboard (installation of the SPD of MP series);
- very low level of surge suppression.
