About the 2081-9027

Transient protector for fire alarm circuits that leave or enter a building, such as DC power up to 200 mA, monitor circuits, audio risers and firefighter telephone risers. It gives line-to-line and line-to-earth protection in a small beige epoxy package. Install it as close as possible to the point where the wiring leaves or enters the building, in a dedicated metal box.

Wiring protected by ILCPs must stay on one contiguous property and must not exceed 3270 ft (1 km).
