1.0 Introduction

The GPRS modem option provides remote communications with any USB-style WebMaster
or WebAlert™ controller, using the ShoulderTap method. This permits changing of set
points, downloading of data files, emailing of reports, and alarm notification.

The user must obtain an unlimited data usage GPRS account from a local cell service
provider, receive a SIM card, and install this in the modem. Once the controller is
programmed correctly it will connect to our ShoulderTap server using a secure connection
over the Internet. This connection will be dropped and restored on a regular basis throughout
the day as a further security measure. It will not be connected to the Internet at the same IP
address for very long.

When you want to ShoulderTap the controller, simply log onto our ShoulderTap server,
identify the controller by its phone number, and you will be instantly connected to the
controller. Its unique user name and password are required to enter the controller.

The GPRS cell service is a data only plan. The modem is not capable of answering a phone
call, and therefore modem-to-modem communications is not possible as it is with the landline
modem option.

2.0 Installation

®

CAUTION! There are live circuits inside the controller even when the power switch on the
front panel is in the OFF position! The front panel must never be opened before power to the
controller is REMOVED!

If your controller is prewired, it is supplied with a 10 foot, 14 AWG power cord with
USA style plug and 8 inch, 18 AWG USA style receptacle cords for the powered
relay outputs. A tool (#1 Phillips screwdriver) is required to open the front panel.

1. Insert the SIM card into the slot as shown below. The notched corner must be oriented to
match the outline silk-screened on the modem
