About the 2081-9044
The 2081-9044 is an epoxy-encapsulated overvoltage protector for low-voltage fire alarm circuits that run outside a building. It limits transients from lightning or power line disturbances on DC power (200 mA maximum), data communications and local energy city circuits, with line-to-line and line-to-earth protection. It goes close to where the wiring leaves or enters a building, in a metal 4 in. square electrical box.
Mount it as close as possible to where the circuit leaves or enters the building, with a 12 AWG ground conductor no longer than 28 ft (8.5 m).
