Chapter 9: Operation
After installation and programming have been completed, the
Skymetry WTU-14 is fully operational. This chapter explains how
the WTU-14 operates.
PART ONE: Alarm Notification and Acknowledgment
There are 3 stages to a complete alarm event: 1) Alarm Recognition,
2) Alarm Notification, and 3) Acknowledgment.
Note that not all fault conditions will go through each stage. For
example, some may not meet the recognition time.
Alarm Recognition
1) The WTU-14 monitors 8 dry contact inputs, 6 analog inputs,
main power, and battery backup. When the status of an input
changes or exceeds user-programmed limits, it causes a fault
condition.
2) If the fault condition lasts long enough to meet its programmed
recognition time, the fault condition becomes an alarm and the
WTU-14 begins the alarm notification sequence.
Alarm Notification
The WTU-14 can send alarms via Voice phone call, E-mail,
Alphanumeric pager, or Text message to wireless (cell) phone.
Dialout Note: Call Progress
The Skymetry WTU-14 monitors call progress when dialing out
in voice mode. If it dials out and encounters a busy signal or no
answer it will wait about a minute and try again up to 3 times. If the
call is answered by an answering machine or voice mail system the
alarm message will likely not be recorded because it will be speak-
ing while your greeting message is playing. Note that since the call
was actually answered, the WTU-14 will consider the call completed
and not dial it again.
