5.3.5 Alarm System
The DAI-2 alarm system monitors the status of the logic-level inputs. When an alarm input appears at one of the
logic-level inputs, the DAI-2 will call the telephone numbers stored in its memory to report the condition. The
telephone numbers will be dialed in rotation starting with the Telephone Number A, then B, C, D, A, B, etc. until the
alarm is cleared or the programmed number of attempts has been made. Program only as many telephone numbers
as needed--blank numbers will be skipped during the dialing sequence.
When it places a call, the DAI-2 will send its identification tones repeatedly as an alert message. This is factory set
to three short beeps. The tones will be sent for the duration of the call unless a user clears the alarm. Press the ❊
key to clear the alarm. The DAI-2 will respond with one long tone as a prompt to enter the security code. Enter the
security code to go online with the DAI-2. Perform whatever actions are necessary in response to the alarm.
There are three mandatory steps to setting up the DAI-2 alarm system:
• program the telephone numbers that will be called when the alarm occurs--starting at address 256
• enable the alarm system by programming the value 1 at address 355
• enable a logic level input by programming a 1 at its control address--starting at address 332
Since alarms are recognized by the DAI-2 on its logic-level inputs, at least one of the logic level inputs must be
enabled in the system profile.
These parameters can be changed to vary how the the DAI-2 alarm system works:
• the time that the alarm input must be present before the alarm is triggered--starting at address 333
• the length of the alarm call and the pause between calls at address 340 and 341
• the number of call attempts per telephone number at address 342
• the site identification tones at address 351
• the speed of the tones at address 352
5.3.6 Programming Suggestions
Any unused actions in the command matrix should be programmed so that they do not interfere with actions that are
desirable. Relays should be programmed with the value 2 on unused inputs so that they will not change state. The
audio switcher should be programmed with value 1 for no change.
The alarm system should only be triggered by logic-level inputs. The matrix has spaces for keys and power up to trip
alarms but this is a side effect of using the matrix for programming--these conditions are not valid.
False relay changes can occasionally occur when program audio is feeding through the DAI-2. Occasionally, but
rarely, the audio will mimic a DTMF tone and be detected as such by the internal controller. If you experience this
problem, try increasing the minimum DTMF length at address 349. This setting changes how long DTMF tones must
be present before they are recognized. Keep in mind that this will also increase the length of time that the keys on
the telephone must be held when controlling the DAI-2.
