Modification
External signaling device connected to the LEF Series.
Difficulty Level
2 – Easy/Moderate – component connection to external points
Components Required
- RY-AC/A : external signaling relay
- External signaling device and its own power supply (not supplied by Aiphone)
Instructions
If only one sub station is to have the capability of activating the external device:
- Connect white wire of the RY-AC/A to the number terminal on the master station of which the door station is connected. Connect the red of the RY-AC/A to the “+” of the LEF master station. Connect the black wire of the RY-AC/A to the “-“ of the LEF master station.
- The yellow leads of the RY-AC/A will provide a normally open dry closure whenever there is a from the door station. Connect this contact in accordance with instructions provided with your external signaling device and power for the external device.
- *If all sub stations need to activate the external device, connect the white wire of the RY-AC/A internally as shown on the schematic (changes difficulty rating to a level 4). The red, black and yellow wires of the RY-AC/A connect as above.
If more than one sub station is in the system, and it is required that all sub stations activate the external signaling device, connect the white wire to internal point. See following schematic.
