When using a Model 449 electrical box, discard the gasket
that is shipped with the box.
•
When using a trim skirt or a surface mount application,
use the gasket that comes with the WG4 unit.
— or —
For flush mount applications on a flat surface, use the
WG4GSKT gasket accessory.
To install the horn:
1. Remove the cover from the appliance by first removing the
six cover screws. See Figure 2, item 1.
2. Position the appropriate gasket over the backplate,
ensuring that the wire slot and other holes line up properly.
Remove the protective backing from the gasket surface
and carefully apply the gasket to the WG4, with the
adhesive side towards the appliance. Press the gasket
firmly against the back surface of the appliance so that the
gasket seats properly.
3. Place the optional trim skirt over the electrical box, if
desired. See Figure 2, items 5 and 6. Also see
“Specifications” on page 3 for a list of compatible boxes.
4. Feed the field wiring through the wire slots on the gasket
and the backplate. See Figure 2, item 3 and Figure 3,
item 1.
5. Align the appliance and trim skirt (if applicable), and then
secure the backplate to the electrical box with the supplied
screws. Check the assembly to ensure that it is securely
mounted.
6. Set the horn volume.
The default horn volume setting is high. To set the horn to
low volume, cut jumper JP3. See Figure 3, item 2.
7. Set the horn pattern.
The default horn pattern is a 3-3 temporal output. To use a
continuous horn pattern, cut jumper JP1. See Figure 3,
item 3.
8. Connect the horn terminals appropriately to the signal
circuit field wiring. You must observe polarity for the unit to
function properly. See “Wiring” on page 3.
9. Position the cover over the backplate and secure with the
six cover screws.
10. Test the unit for proper operation.
