Extra - Door station settings - Relay settings NO or NC

• The Relay ID is the relay to select for the settings.

• Type in the state of the relay, NO or NC (Normally Open or Normally Closed)

• Mode Monostable or Bistable

• A relay is an electromechanical device that is used to control the flow of electricity in a circuit. It works by using an electromagnetic field to open or close a switch, which in turn allows or blocks the flow of current.

• A monostable relay is a type of relay that is designed to turn on and off when a voltage is applied. Once the voltage is removed, the relay returns to its resting state. Monostable relays are often used as timers or to control a device for a limited period of time.

On the other hand, a bistable relay is a type of relay that remains in one state until a voltage is applied. Once a voltage is applied, the relay switches to the other state and will remain in that state until another voltage is applied. These relays are often used for switching devices such as lamps, motors, and other devices on and off that must remain in one state until a new voltage is applied

• Trigger Delay in seconds
• Hold Delay in seconds
• DTMF Mode the number of digits max 4 (these are the tones to activate the selected relay)
• 1 Digit DTMF is to select the DTMF tone
• 2~4 Digits DTMF to enter the DTMF digits
• Relay Name this can be very useful when having more than one relay in use
