HAI Part Number: 70A00-2
The HAI C3 (Cellular Communications Center) is a wireless cellular
communicator that allows phone calls to be made over the
GSM cellular network using the existing telephones in your
home. The HAI C3 can be used when there is no land line in your
home or if the land line is temporarily unavailable.
The HAI C3 is perfect for homeowners without land lines, vacation homes, and locations
that need remote monitoring.
The 70A00-2 now includes Caller ID to display the number of calling party.
The HAI C3 works with any standard security panel, including HAI's Omni family of
home controllers, to communicate alarm conditions using the GSM cellular network
when the land line or cable phone service has been cut.
The HAI C3
checks the status of the existing PSTN telephone line and
if it is unavailable, the HAI C3 will emulate the line signal to the
security panel. When an alarm occurs, the security panel will
dial out using the GSM cellular network to communicate with
the central monitoring station and the central monitoring station will be able to
call your home through the C3 to verify the alarm condition.
The HAI C3 ships with an included backup battery in case the power goes out.
How It Works
There is no programming involved with the HAI C3. It provides better sound quality than regular cell phones because the
attached antenna is better and more powerful than the one on a cell phone.
Regular telephones connected to the HAI C3 can be used to make calls. If a land line is
present, you will hear the normal dial tone and you can make
your call as normal using the land line service. However, if the
land line is currently unavailable, you will hear a different tone
which indicates the HAI C3 is in cellular mode and the call will be
made using the cellular network.
If the land line is available,
but you still want to make the call using the cellular network,
when you pick up the phone and hear the normal dial tone,
press the * key on the phone and the HAI C3 will switch to GSM
mode. At that point, you will hear the cellular mode tone and
you can make the call using the GSM cellular network. When
a call is made to the phone number assigned to the GSM SIM
card installed in the HAI C3, any phones that are connected
to the HAI C3 will ring as they normally would when a land line call
Note that due to the limitations of cellular service, the HAI C3 does not work with faxes or modems.
The HAI C3 will work with regular home telephones, speakerphones, and answering machines.

The HAI C3 requires a GSM Mini-SIM card (25 mm × 15 mm) and cellular service. The major GSM players in the United States
are AT&T, T-Mobile, and prepaid carriers. Customers with existing GSM accounts can add a line to their
cellular account for a reasonable charge and plug the added phone SIM into the HAI C3.
