The module is designed to protect the central units of alarm systems from surges and lightning strikes. It has 8 protective channels intended for alarm sensor signals and one common protective channel for their power supply. The product is made in the form of a module, mounted in a dedicated housing along with other modules, which can create a comprehensive protection system for all signals of the alarm central.

The device's task is to eliminate surges induced in alarm wires during a lightning strike. The solutions used also eliminate spark jumps trying to penetrate the alarm system from other installations and discharge the electric charge to the ground. It is dedicated for use with sensors installed inside the building.

Each alarm line has independent protective circuits with an effectiveness of 2kA, using super-fast MOSFET fuses, which prevents voltage impulses above 18V from reaching the protected side. This creates an effective protective barrier for any type of alarm system, while not affecting even 4-state alarm circuits. The standard of terminals for the threatened side and the protected side has been maintained according to the standard for connecting in alarm central units, ensuring ease of installation and later servicing.

The product cannot be used for digital (bus) lines; another model of protective device should be used for this purpose.

APS-8Zi/1P has one protective channel for the power supply line, to which all power wires from the sensors of the entire module are connected. The double terminal on the protected side facilitates the connection of a larger number of wires. Since a short circuit in one of the power supply circuits will trigger the alarm central's protection and disconnect a larger number of sensors from the power supply, the solution with a common power supply is not recommended for external sensors. For the mentioned solutions, an additional module APS-8P should be used.
