A
Shield Tech Security STS-GSMC-4G
GSM Dialer has been tested and found to be a viable alternative to the
“POTS” line connection. The Shield Tech Dialer emulates the “POTS” line by providing DTMF tones and line
voltage.
Requirements:
•
Active AT&T cellular SIM card/monthly fee
Disclaimers:
The 4800 offsite notification process requires a standard “POTS” line for proper operation. As with any
method of offsite voice connection, if the phone service, internal/external network or power system
fails, the 4800 system will not be able to connect to the offsite monitoring location.
The example Cellular service disclaimers below are generally included with service contracts.
The 4800 system phone line circuit is checked every 24 hours for proper operation. A notification of a fault will
be shown on the Control Panel(s) display, in the event of a failure.
•
You may experience interruption of Service (or of certain features of the
Service) or degraded service quality at any time and without notice. You will
likely experience Service outages in the event of electric power outages
affecting your business.
•
Just as VoIP phone line service can fail, cellular service can also fail, preventing
an alarm condition from being reported to a monitoring location.
