Tone Selection
The D1x Alarm Horn Sounders have 64 different tones that can be
selected independently for the first and second stage alarms. The
tones are selected by operation of the tone setting DIP switch 1 & DIP
switch 2 (see fig 10) on the PCB, for stage 1 and stage 2 respectively.
Default = Switch 2
S2 - Tone 1
0 0 0 0 0 0
Default = Switch 1
S1 – Tone 44
1 1 0 1 0 1
(ON = 1, OFF = 0)
Fig 10: DIP switch configuration
The sounder can also be switched to sound the third and fourth stage
alarm tones.
The tone table (D221-95-001-IS) shows the switch positions for the 64
tones on first and second stages and which tones are available for the
third and fourth stages dependent on the Stage 1 DIP switch setting.
