Mircom INX-10A short-circuit isolator module for addressable SLC loops on Mircom intelligent fire alarm control panels.

Compliance

• UL 864
• NFPA 72
• ULC S527
• FCC compliant

Key features

• Inline fault isolator for addressable SLC loops; opens the loop segment in the event of a wire-to-wire short and restores it after the fault clears
• Protects the remainder of the SLC loop from communication loss caused by a localized short between adjacent isolator points
• Designed for use on Mircom intelligent SLC loops associated with the FX-2000, FX-3500, and FleX-Net family of fire alarm control panels
• Operating voltage drawn from the SLC loop at the panel’s standard 15 to 32 VDC range
• Mounts in standard electrical backboxes used for Mircom field devices

Short-circuit isolators are required by NFPA 72 and Canadian fire codes between defined groups of addressable devices on Class A and Class B SLC loops so that a single wiring fault does not disable an entire loop. The INX-10A is Mircom’s inline isolator module for this purpose: it detects a short between its loop input and output terminals, opens the affected segment to protect the rest of the SLC, and re-closes automatically once the fault is cleared during service. Quantity and placement of isolators is determined by the engineered drawings for the specific Mircom panel program and must follow the SLC loop topology rules published in the panel installation manual.

Verify panel/device family compatibility before ordering.
