YSI 5200 - Manual (Page 89)

YSI Incorporated 87 5200 Recirculating System Monitor
Alarm Logic Flow Charts). After the Alarm Hold Off period expires, the audible alarm (a standard
feature) will activate. If the 5200 is configured and enabled for alarm pager support, an alarm page will be
sent indicating which parameter is in alarm state (pH, ORP, Temperature, etc.) and the type of alarm it is
(high alarm, low alarm, etc.). This information is transmitted via modem (the 5200’s modem or a
computer running AquaManager software and equipped with a compatible modem) to your pager. The
page consists of the last three digits of the serial number of the YSI 5200, followed by a seven digit alarm
code as indicated below.

After the serial number of the unit, the first digit always refers to pH status, the second digit indicates
ORP status, the third digit indicates temperature status, the fourth digit is conductivity status, the fifth is
DO status and the last two digits are Aux Input #1 and Aux Input #2. Table 9-1 shows the possible alarm
conditions and the codes that are displayed. Note that a “0” in any digit location indicates that no alarm
condition occurred for that parameter.

NOTE: The 5200 also sends code 8888888 if back-up power is lost, but primary power is still present.
As an example, an alarm for a YSI 5200 unit with serial number 52-003598 was activated, indicating a
high pH and low ORP condition, the page would appear as follows:
“598 2100000”
If your system has backup power, you will receive pages through the power fail detect feature. If power
fails on a unit that has no backup battery, when the power comes back on, the unit will dial the phone
pager and send a power out message. (All zeros mean the unit has powered back up after a power outage.)
Pager Phone Number
The first step in programming the YSI 5200 for pager support is the entry of the phone number you want
the 5200 to dial in the event of an alarm condition.
Dial Modifiers
Depending on your situation, you may need to use the dial modifiers listed below. These are special
parameters that tell the modem what, when and how to dial the telephone number.
