YSI 5200 - Manual (Page 90)

YSI Incorporated 88 5200 Recirculating System Monitor
Dial Modifier Description
, Delay for approx. 1 second
W Wait for dial tone
The ‘W’ dial modifier is particularly important to make sure that there is a “dial tone” before initiating a
page.
Pager Phone Number Example
The following is an example of one scenario where the pager number requires a bit more than the phone
number:
To reach the pager, it is necessary to:
• Dial 9 for an outside line.
• Wait for the dial tone.
• Dial the paging company.
• Wait a few seconds for the paging company to answer the phone and accept a pager input.
The pager number to be used in this example would be:
9W16195551212
NOTE: To perform the last step (Wait a few seconds…), see the Pager Delay Section below.
Pager Delay
Every pager service company processes pager calls differently. It is important that the YSI 5200 does not
start sending information before the pager company is ready to receive it.
The pager delay time is the number of seconds that the YSI 5200 waits after it has dialed the phone
number before it sends the serial number and alarm values. For example, if your pager service has a
message that precedes the transmission of a page, you will need to time the message period and program
this time period into the Pager Delay. If the interval is set for too short a period, the serial number and
alarm code will not be properly processed by the paging system. If the time period is set for too long a
period, then the pager service company may terminate the call before the alarm code information is sent.
A good starting value is 5-10 seconds.
Pager Retries (Redial)
The pager retry timer is activated if the YSI 5200 is unable to send a page due to a busy phone line. The
controller will wait the number of minutes specified by this command and attempt to send another page.
The default value is 3 minutes. Valid times are from 0 to 120 minutes.
Pager Retransmit (Until Reset)
When an alarm condition is detected (and after the hold-off period has expired), the 5200 will send a
pager alarm. The YSI 5200 is programmed to continue paging until the alarm is reset (someone physically
pushes a key on the front of the YSI 5200).
The pager retransmit value sets the length of time that the controller waits before it pages again—
assuming that the alarm has not been reset.
Pager Tone/Pulse
The Tone/Pulse setting controls whether the modem uses tone or pulse dialing. If you have a rotary
phone, select pulse as shown below; otherwise, use the default setting, tone.
