Temp/Non-Temp:
Temporal coding or Non-Temporal coding can be selected using the
jumper plugs located on the printed circuit board. With the jumper
offset, the tone pattern is the Temporal Coded Signal. With the
jumper in place, the Non-Temporal code (continuous) tone is active.
High/Low Volume:
High or low volume may be selected using the jumper plugs locat-
ed on the printed circuit board. With the jumper in place, the
sound output level is the high level. With the jumper offset, the
sound output level is the low level. The low volume setting must
NOT be used when the device is powered from a 12-volt panel.
NOTE:
Always power down devices before setting jumpers.

1. Mount back box in desired location.
2. For SpectrAlert models, mount plate to back box using 4 screws.
3. Complete field wiring.
4. Remove paper liner on gasket –
NOTE: Perform electrical tests first,
then remove liner. Paper liner must be removed from gasket before
final installation.
5. Insert locking rib into slot on plate.
6. Press into plate, the SpectrAlert model will make a “click” when it has
locked into place.
Note: The weatherproof or outdoor notification appliance must be used
with a WBB back box when installed in applications requiring the
appliance to be weatherproof or outdoor-listed. In such applications,
using a back box other than the WBB will void the UL designation.

Figure 5: Removal of horns and strobes from mounting plates:
To remove units from mounting plates, insert Quick Click Removal Tool
as shown to unlock snap. While pushing in Removal Tool to release the
snap, pull back on the horn/ strobe. Hinge the horn/strobe module, dis-
engage the Locking Rib, and lift the horn/strobe away from the mount-
ing plate.
