ANN-BUS Devices Installation
Mounting
The ANN-80 can be surface or semi-flush mounted to a single, double or 4” square electrical box.
Select and remove the appropriate knockout(s), pull the necessary wires through the knockouts and
mount the annunciator in or on the wall depending on the type of installation desired.
The ANN-SB80KIT(-R/-B/-W) is an available mounting kit for the ANN-80 annunciator. The kit
comes with a surface backbox and surface wedge for angled viewing. The two pieces can be used
separately or can be stacked together.
The ANN-80 cover must be attached to the annunciator backplate before mounting the annunciator
to the electrical box/wall. The cover cannot be reattached or removed after the annunciator has
been mounted.

block TB1.
2. Remove appropriate amount of wire insulation.
