5. ALARM PARAMETERS
5.1. Summary of Events
An alarm is detected:1.
The system waits for the end of the Recogni-
tion Time before validating the alarm.
An alarm is validated:2.
When the Recognition Time has elapsed, the
Agri-Alert activates the siren output (if ap-
plicable) and delivers a message on-site
to report the alarm (unless the voice mute
function is enabled). It then waits for the
end of the Start Call Delay before launching
the dialout sequence.
Dialout Begins:3.
When the Start Call Delay has elapsed, the
system calls each phone number in the dia-
lout sequence (each call is separated by the
Time Between Calls delay). If a phone number
is busy, the Agri-Alert places it at the end
of the dialout sequence and redials it later if
required (Busy Tries parameter).
If the Agri-Alert reaches a home phone or cell
phone, it communicates the alarm message
orally (the Message Repetitions parameter tells
the number of time the message is repeated)
In addition, if the speaker is enabled, the
Agri-Alert also delivers the alarm message
on-site.
If t h e sy s te m re a ch e s a pag e r, i t s e n ds a n a lar m
code which tells the nature of the alarm.
The Agri-Alert goes on with the dialout se-
quence as long as the number of calls of the
dialout sequence is not reached or as long
the alarm is not acknowledged (the alarm
can either be acknowledged on site or over
the phone).
The alarm is acknowledged:4.
When the alarm is acknowledged, the system
stops the dialout sequence and the siren. If
the alarm was acknowledged by phone, the
user can listen to on-site sounds during the
delay defined for the on-site listening.
5.2. Internal System Alarms
The Agri-Alert system can detect certain
internal alarm conditions. When an internal
problem occurs, the Agri-Alert acts as if it
was a zone alarms: it activates the siren,
launches the dialout sequence, etc.
The table below gives a list of possible in-
ternal alarms:
Alarm type Recognition
Time
Low battery 30 seconds
Siren defect 30 seconds
12VDC output defect (The
device connected to the 12VDC
output exceeds 500mA)
60 seconds
16 VAC input defect 60 seconds
Phone card disconnected 30 seconds
Phone line cut 30 seconds
Outdoor card disconnected /
defect
30 seconds
No dial tone 3 trials
5.3. Outdoor Temperature
Compensation
The outside temperature probe can be used to
prevent false temperature alarms that are due
to warm weather conditions. When the out-
side temperature is already warmer than the
high alarm limit, the controller automatically
changes the high temperature alarm limit. The
high limit becomes the outside temperature
+ offset. In other words, when the outside
temperature is too high, the high temperature
alarm is only set off if the zone temperature
exceeds the outside temperature by more
than X degrees (X being the offset value). The
graph below illustrates this situation.
Critical Temperature:
The critical temperature is the absolute
maximum temperature allowed in a zone.
No matter what the outside temperature is,
the zone temperature must never exceed the
critical temperature. Refer to section 5.5.2 to
set this absolute temperature limit.
