Device Repair and Return

The UVU-140-A and UVU-140-AR fire detectors are not designed to be repaired by the customer in the field. If a problem should develop, first carefully check for proper wiring and programming. If it is determined that the problem is caused by an electrical malfunction, the unit must be returned to the factory for repair.

Net Safety Monitoring Inc. encourages its distributors to make advance replacement units available to the user during the warranty period. This allows Net Safety Monitoring Inc. to take time to repair the unit completely while users keep their operations running with the advance replacement unit.

Prior to returning items, contact the nearest distribution office so that an RMI (Return Material Identification) number can be assigned. A written statement describing the malfunction must accompany the returned item to simplify finding the cause of the failure and reduce the time and cost of the repair. Pack the item to protect it from damage and use an anti-static bag or aluminum-backed cardboard as protection from electrostatic discharge.
