Uplink launched a lifetime guarantee for all of its 2G cellular communicators. Alarm companies will be able to enroll individual Uplink 2G units in the guarantee program for a nominal set monthly fee, according to the company. Should enrolled devices be rendered inoperable by a permanent, carrier-initiated change in the type of cellular service, Uplink will provide an exchange unit to the alarm company. In addition, the guarantee plan includes existing installed products against defects for as long as the communicator is enrolled in the program. The lifetime guarantee is available to alarm companies only.
