I.Model 800 Detects a Change at the Sensor
• Model 800 detects a change in the
monitored condition (from the sensor
wired to one of the zones). This is
considered an alert condition, and does
not qualify as a valid alarm at this point.
• The condition continues throughout the
programmed Recognition Time. If the
condition (or sensor) reverts to its normal
state before the Recognition Time is
reached, no alarm will occur.
II. A Valid Alarm Is Recognized
• The condition must persist long enough
to meet or exceed the programmed
Recognition Time. When Recognition
Time has expired, but the alert condition
continues, the Model 800 will determine
that a valid alarm exists.
• When a valid alarm is determined, Call
Delay is activated, forcing the Model 800
to wait for a programmed period of time
before starting the dial-out process. Call
Delay applies to the period just prior to
dial-out, before the first telephone call is
made.
• Call Delay provides the opportunity to
cancel a valid alarm at the Model 800's
installation site, before dial-out occurs.
An audible voice message indicates
which of the zones is in alarm. If on-site
personnel acknowledge the alarm within
the Call Delay time, the Model 800
will not dial out. (Local Voice Mute is
disabled, so that alarm messages can be
heard at the site.)
