We present surge protection devices for Intrusion and Hold-up Alarm Systems. Taking into account the specific operation of alarm control panels, considering the diversity of their designs and signal configurations, we have created universal and effective solutions that protect against the effects of atmospheric discharges. They provide protection for alarm line circuits, power supply, communication buses, and siren circuits. The use of MOSFET technology, known from LAN surge protectors, has resulted in products with high effectiveness and compatibility with almost all control panels available on the market.
