Detailed Description
The Anwetech AT-IS103 Short Circuit Isolator provides intelligent protection for addressable fire alarm systems by isolating faulty segments in the event of a short circuit.
It operates with a 24V nominal voltage (16–28V range) and ensures rapid isolation at 11V while automatically reconnecting at 4V.
This isolator supports up to 32 devices per loop, allowing for reliable and scalable fire system installations.
The LED indicator provides clear visual feedback — flashing during polling and illuminating when isolation or alarm occurs — to simplify troubleshooting and maintenance.
Built with a flame-retardant ABS enclosure, the AT-IM101 performs reliably in harsh environments ranging from -10°C to +55°C, ensuring long-term system stability.
Its low current design (<3mA) and automatic recovery mechanism make it ideal for use in industrial facilities, commercial buildings, and infrastructure projects requiring uninterrupted fire protection.
