ALARM DELAY
This is a customer preference option. This option establishes the minimum time delay before a loss of
voltage condition is registered by the scanner. The option range is from 30 seconds to 8 minutes.
Times (shown in seconds and minutes) are additive. Longer alarm delay times are recommended to
prevent alarming of temporary power interruptions.
Example:
For a 2 ½ minute delay; turn on the 30 second and 2 minute switches:
Figure 14
ALARM SILENCE BUTTON
This button will temporarily silence the remote alarm (up to 24 hours depending on the program pins; see
the Programming section for “
Alarm Silence Time-out
”). While corrective actions are being taken on
failed circuit(s) the alarm will re-enunciate if a new circuit fails when the system is silenced. Pressing the
“
Alarm Silence Button
” will silence the remote alarm relay and reset the timer.
When voltage has been restored to all of the failed circuits, press the “
Alarm Reset
” button to clear all
alarms from the system if the “ Manual Reset
” has been selected.
