Purpose

The following procedures verify the customer defined alarms and relay

contacts are functioning properly. These tests are performed on all AMR

alarms/relays in a sequential manner until all have been verified. Perform

these procedures periodically to ensure the external alarms are reported

properly. Following these procedures ensures continued peak system

performance.

Study the site engineering documents and perform the following tests

only after first verifying that the AMR cabling configuration required to

interconnect the BTS frame with external alarm sensors and/or relays

meet requirements called out in the SC 4812T Series BTS Installation

Manual.

NOTE

Motorola highly recommends that you read and understand this

procedure in its entirety before starting this procedure.
