Alarm Format
This parameter changes the format of the B1290 alarm inputs to match the output of your monitoring devices in
the field. Normally open inputs indicate an alarm when the input is grounded, and when the ground signal is
removed, the alarm is interpreted as having cleared. Normally closed inputs are grounded in their normal state,
and open when an alarm occurs. Latched inputs recognize a pulse as an
alarm. After the pulse has disappeared,
the input is deemed to be in the alarm condition until it is acknowledged.
Note
: A latched alarm should provide a short, predictable pulse to the input of the ProTalk Plus; otherwise, it
may have to be acknowledged twice. If the alarm is acknowledged while the input is active, the alarm will not
be cleared and new alarms will not activate that input.

Alarm Timer (Debounce) Timescale
The debounce timers on the alarm inputs can operate with a resolution of .1 seconds or .1 minutes. When the
B1290 speaks ‘seconds’ for this value it is indicating that the timer is counting in .1 second steps and when it
speaks ‘minutes’ it is counting in .1 minute steps.

Default:
0 ( seconds)
Alarm Delay (Debounce)
This parameter controls the amount of time an alarm must be present before it actually registers as an alarm.
This feature is often used to eliminate fleeting alarms, where the device in the field does not present a clean
closure to indicate an alarm, but a series of bounces on the contacts. Another example might be to overcome
momentary power fluctuations which cause false alarms to be reported. The debounce on each alarm may be
individually set.
