Horn selections using 3-position DIP switch on horn/
strobe (refer to Figure 3):
Note: When powered from a FWR supply, the horn will be
modulated (turned on and off) by 120Hz causing it
to sound different than if powered by a DC supply.
High/Low Volume
ON=High Volume, OFF=Low Volume
Note: The low volume setting of some tones must NOT be
used for public mode applications when the device

The Selectable Output Horn/Strobe may be commanded
to override the horn selection. Horns and strobes may be
overridden to the patterns listed below:
1. Continuous EM
2. Temporal EM
3. Double March Time EM (240 strokes/min.)
4. March Time EM (120 strokes/min.)
5. Canadian EM (20 strokes/min.)
6. Strobe Disable
7. Strobe Enable
