MONITOR FAILURE

The Heart Beat Monitor is not designed to be repaired in the field. If a problem should develop, first check the
battery condition and continuity of the test leads. In addition, remember that multiple LON faults (opens/shorts) can
isolate nodes from any heart beat. In this event no LED’s will illuminate. If this is suspect check for a heartbeat
directly from the output terminals of the Gateway or LCU module.
If it is determined that the problem is caused by an internal electronic defect in the monitor, the device must be
returned to the factory for repair. See directions below.

DEVICE REPAIR AND RETURN

Prior to returning devices or components, contact the Detector Electronics Minneapolis MN office so that an RMI
(Return Material Identification) number can be assigned. A written statement describing the malfunction must
accompany the returned device or component to expedite finding the cause of the failure, thereby reducing the
time and cost of the repair.
Pack the unit or component properly. Use sufficient packing material in addition to an antistatic bag or aluminum-
backed cardboard as protection from electrostatic discharge.
Return all equipment transportation prepaid to the Minneapolis factory location below, and c/o the Returns goods
department.
