ABSTRACT:
A premise-monitoring alarm system has a base transceiver for a control panel and numerous distributed remote transceivers servicing the numerous distributed remote alarm-event sensors. Given remote transceivers are enhanced with a user-sensible indicator as well as a user interface. For installation purposes, a remote transceiver responds to a manual trigger through the interface with transmission of a test signal. The base transceiver responds to any within-range test signal with sending a reply signal. In turn, the sending-remote transceiver responds to reception of the reply signal with output of a user-sensible indication through the user-sensible indicator. That way, during installation, a single installer can determine when the two transceivers are within range without help from additional persons or equipment. Hence the installer can repetitiously test the sending-remote transceiver in various proposed installations within a confined remote perimeter, without ever having a desert area confined within the perimeter.
