Why Protect?
One of the essential components of a building is the security system, be they used in a family house, office building, shopping center or industrial facility. The rule of thumb is that the larger the facility, the higher the risk of potential transfer or overvoltage.
You can imagine the security system (Electronic Alarms, Fire Security Systems or Access Control Systems) as a wide network of sensors, cameras, switches and other minor components where the lengths of the interconnection cables may take up to several hundreds of meters. The induced overvoltage (e.g. due to direct or indirect strike of lightning – LEMP or switching voltage – SEMP) in these long lines may result in damage of the sensors or the control unit itself, in addition to issuing of false alarms. Use of additional SPD for the security system is the recommended preventive measure that multiplies its operational reliability and credibility.
The illustration shows an example of choosing and deploying SPD security features for an access system applicable analogously to electronic security and fire systems.
What to Protect?
- Power supply protection combined with RFI filter
- Sensor’s data transmission and power supply lines
- Ethernet and IPTV networks
- Direct phone alarm lines to control panels
