5.5.8 DTMF Hold Time
The DAI-2 is controlled by the DTMF tones produced by a TouchTone® type telephone. It is normal for audio passing
through the system to occasionally contain sound at the same frequencies as these tones. To reduce the chance of
reacting to these false tones, the DAI-2 is programmed to ignore any tone until it has been present for a set length of
time. DTMF hold time is programmed at address 349.

5.5.9 Identification Tones
When the DAI-2 places a telephone call to signal an alarm condition, it sends a series of short tones to identify itself.
It will repeat these tones until the alarm is cleared or the programmed call length is reached. It may be necessary in
cases where more than one DAI-2 is used to distinguish between the units when they call. Simply program a different
value at address 351 to send a different number of identification tones.

The DAI-2 responds to user input through a series of short tones representing numbers. The speed of these tones
can be increased or decreased to suit different users. The tone speed is programmed at address 352.
