5.8 AC Power Monitoring Enable/Disable
The Model 1108 monitors AC power failure. This command
enables or disables the power failure detection feature. When
enabled, the Model 1108 will monitor power and dial out when
AC power failure exceeds a programmable span of time (refer
to AC Power Failure Recognition Time, Section 5.9).
The default setting for AC power monitoring is enabled (on).
When disabled, the Model 1108 will not dial-out to report
power failure.

5.9 AC Power Failure Recognition Time
The AC Power Failure Recognition Time is the length of time
that AC electric power is off before a valid alarm is recognized
and dial-out begins. The default setting is 5 minutes, 0 seconds,
but is programmable from 0 seconds to a maximum of
272 minutes.
When AC power failure occurs, and throughout the pro-
grammed Recognition Time, the Model 1108 steadily repeats
the message “the electricity is off” at the unit’s installation site.
There is no Call Delay programming available for AC power
failure. Immediately following Recognition Time, the Model
1108 begins the dial-out process to report power failure.
