The MB3x70 relays can be used as follows:

• The MB3x70 relays can be connected to alarms to notify control center administrators when the MGate device loses power supply. The relay is triggered when both the power supplies (main and redundant sources) are cut off.
• The relays provide two modes.
  1. Relay is open = Power supply is ON
  2. Relay is closed = Power supply is OFF
• The relays can only have the preset two modes and cannot be programmed further.
