  If the Power LED is not lit on your Eaton Industrial Electrical, you should first check the polarity and integrity of the trunk cable connections to the enclosure. Also, verify that the d.c. supply powering the incoming trunk is operating correctly.

What to do if alarms on my Eaton Security System remain on and cannot be reset?
- C
  Candace ThomasAug 25, 2025
  If alarms are set to operate from normally closed contacts and the signal supply fuse blows, all alarms will operate as though an alarm has occurred. To resolve this, check the signal supply fuse F1 (rated at 125mA), located in the top right-hand corner of the unit when viewed from the rear, to see if it has blown. Also, ensure that the inputs have been correctly set to operate from either a normally open (N.O.) or normally closed (N.C.) configuration and haven't been accidentally inverted.

  Each channel can be selected to operate either of the two integral horns / horn relays as required. Internal horns and horn relays are enabled by placing the following switches to the ON position on the SPR Card: HNA – SW5 - Position 5, HNB – SW5 - Position 6. Each pair of channels can be set to activate either of the audibles using the following switches located on each alarm module: Channel 1 & 2 HNA – SW4 Position 7 set to ON, HNB – SW4 Position 8 set to ON; Channel 3 & 4 HNA – SW6 Position 7 set to ON, HNB – SW6 Position 8 set to ON.
