Since the pager message is only transmitted once, the Acknowledge Bit (#R100.16) is not used. If the pager
message was to be transmitted more than once (by configuring a 1 in the 2nd Group and 3rd Group of the
1st Sequence), writing a 0 to #R100.16 would acknowledge the pager message and stop the pager message
from being re-transmitted.
GSM SMS Pager Messages
A GSM can be used on any CPU serial port (PC-1, CP-1, CP-10/11/21, LP-1/2/3) to send an SMS message
to any mobile phone (Optus, Vodaphone, Telstra etc). When using a GSM instead of a PSTN modem,
configure Pager Type as GSM SMS and leave Phone No. and Password blank (these settings are not used).
A GSM allows a single pager message to be sent to multiple phones when a sequence with multiple phone
numbers is used (eg. as shown in the 4
th
Sequence above).
Dial-Up SMS Pager Messages - Sending To Multiple Mobile Phones
After obtaining a password, Telstra's SMS Access Manager allows each pager message to be sent to
multiple pager numbers (this would occur if a pager message block was configured with Pager Sequence 4
as shown above). If the paging service only allows one message to be sent to one phone number at a time
(eg. if using the Telstra paging service and the mnmail password), a message can be sent to multiple
phones by:
• Configure 1 phone number in each pager sequence (eg. as shown in pager sequences 1 to 3 above)
• Configure ladder logic that triggers 1 pager message block for each phone number when an alarm
occurs. Each pager message block should be configured to use a different sequence number that
corresponds to the phone number.
The example below shows how each time the Mains Fail alarm occurs, 3 pager messages are triggered that
target different phone numbers.

Telemetry System Paging
It is best to configure all the pager messages in the master RTU for two reasons:
• The amount of communications in the telemetry system is minimised.
• To enable or disable the pager receivers that messages are sent to, the bits in only one group register
need to be changed instead of changing the group register in every RTU that initiates pager messages.
New data is usually exception reported to the master RTU and so this new data can be used to trigger a
pager message.
