NOTE: Factory default setting is 1.0K Repeating 1 Second Chime set at High volume.
The chime section only tested at the 8-17.5 and 16-33 Volt-FWR/DC limits. This does not include the 80% low-end or 110%
high-end voltage limits.
Chime Selection
Chimes are factory set for high volume, 1.0K repeating 1 second
chime. Tones may be selected by making the appropriate settings
on the DIP Switch located on the printed circuit board. The set-
tings required for the available tone options are as follows:
