Industrial installations may have strong electromagnetic interferences. In order to isolate and protect the SLC loops and 24 VDC outputs from electromagnetic interference install Telefire's EPI-3000 Electromagnetic and Surge Protection Interface Module. One EPI-3000 module will isolate all four loops, and both 24 VDC outputs (24V_A and 24V_B) of a single ADR-3000 fire alarm control panel.

Industrial installations may have strong electromagnetic interference. Install Telefire's EPI-3000 Electromagnetic and Surge Protection Interface Module in order to isolate the SLC loops and 24 Vdc outputs from electromagnetic interference. One EPI-3000 module will isolate all four loops, and both 24 Vdc outputs (24V_A and 24V_B) of a single control panel.

When installing a system at a site adjacent to high power cables, heavy industrial machinery, or any kind of high electromagnetic fields, shielded cables should be used in the SLC loops and an EPI-3000 module should be connected to each ADR-3000.
