The I1-AIS-300 Isolator Module is designed to limit the effect of short circuits on the loop of an addressable fire alarm system. When a short circuit occurs, the affected section is isolated, helping the remaining devices on the loop continue operating.

The module requires no addressing or separate external power supply and can be used with WISE series and other compatible SENS addressable fire alarm control panels. A section containing up to 30 elements can be protected by an isolator. Once the short circuit is cleared, the module automatically returns to normal operation.

With its compact construction, low power consumption and SMD technology, the I1-AIS-300 provides a practical solution for maintaining loop continuity in addressable fire alarm systems. It is designed in accordance with EN 54-17.
