Reset a Decoder Power Alarm

Some Resi hardware decoders have two power supply modules. Each power supply module has enough capacity to allow your decoder to operate from a single power source in the case of a power outage. Resi recommends that each power supply should be plugged in to separate circuits, at least one of which should have a battery backup.


Power Outage Scenarios

In the case of a power outage and based on your setup, one the following scenarios may occur: 

  • No battery backup - If both of your power supplies lose power while your decoder is powered on, your decoder will shut off immediately.
  • One battery backup - If only one of your power supplies is plugged into a redundant power solution (UPS) and your decoder is powered on, an alarm will sound from your decoder’s unpowered power module. You can either plug that module’s power cable into a powered circuit or reset the alarm. If your remaining power supply loses power, your decoder will shut off immediately.
  • Dual battery backup - If both power supplies are plugged into a redundant power solution (UPS) and your decoder is powered on, your decoder will not sound an alarm (although you may hear alarms from your UPS). Your UPS capacity will determine the remaining run-time of your equipment.

Silence the Power Alarm

In order to silence the power alarm, you must have access to the back of your decoder.

  1. Identify which power module has lost power (this is indicated by a red light near the IEC connection).
  2. Press the red light in to turn off the alarm.
  3. Resolve the power source issue or wait for power to return.
