The F&F AS-224 staircase timer switch is a specialized electrical control device designed to manage lighting systems in residential and commercial buildings. Operating on a 24V AC power supply, this unit is engineered for seamless integration into standard electrical cabinets via DIN rail mounting. Its primary function is to automatically deactivate lighting after a pre-configured time interval, which helps optimize energy consumption in areas with intermittent traffic.
Advantages
This timer switch offers a robust solution for automated lighting control, ensuring that lights remain on only when necessary. By automating the switch-off process, it significantly reduces electricity waste in common areas. The device is built for durability and reliable performance in standard indoor environments, featuring a compact design that saves space within distribution boards. Its compatibility with 24V AC systems makes it a safe and effective choice for specific low-voltage lighting installations.
Suitable for
- Stairwell lighting control
- Corridor and hallway illumination
- Automated lighting in residential buildings
- Commercial facility lighting management
This device is not suitable for high-voltage (230V) lighting circuits, as it is specifically designed for 24V AC systems. It should not be installed in environments with high humidity, dust, or outdoor conditions, as the IP40 rating does not provide protection against water ingress or harsh environmental factors.
Key specifications
- Supply voltage: 24V AC
- Mounting type: DIN rail (TH-35)
- Protection rating: IP40
- Application: Staircase and corridor lighting control
To use the F&F AS-224, ensure the device is mounted securely on a standard DIN rail within a protected electrical enclosure. Connect the power supply and the lighting circuit according to the provided wiring diagram. Once installed, adjust the time interval settings on the device to match the required duration for the lights to remain active after being triggered.
What to consider before purchase
- Verify that your lighting system operates on 24V AC
- Ensure the installation location is dry and protected (IP40)
- Confirm availability of space on your DIN rail
For optimal performance and safety, ensure that all electrical connections are tightened correctly and that the total load of the connected lighting does not exceed the technical limits of the switch. Periodic inspection of the connections is recommended to maintain system reliability.
