## Long description

The F&F BIS-410 is a flush-mounted bistable relay engineered for efficient lighting control in residential and commercial environments. This device enables the switching of electrical circuits from multiple locations using pulse-based signals, providing a flexible solution for modern electrical installations. It is specifically designed to work seamlessly with illuminated push-buttons, ensuring compatibility with standard wall-mounted control interfaces.
Advantages
The primary benefit of the BIS-410 is its integrated timer function, which allows for automatic lighting deactivation after a preset period, contributing to energy efficiency and convenience. The flush-mounted design ensures a clean, professional installation that remains hidden behind standard wall switches. Its compatibility with illuminated buttons eliminates common flickering or ghosting issues often found in standard relays, making it a reliable choice for complex lighting setups.

Key specifications
Mounting type: Flush-mounted
Control input: Compatible with illuminated push-buttons
Function: Bistable relay with integrated timer
Application: Lighting control systems
To use the BIS-410, the device must be installed in a standard electrical wall box behind the push-button. Wiring should be performed by a qualified professional according to the provided technical diagram, ensuring that the control circuit is correctly connected to the pulse inputs. Once installed, a short press of the button toggles the relay state, while the internal timer manages the duration of the output signal.
What to consider before purchase
Ensure the total load of the connected lighting does not exceed the relay's rated capacity
Verify that the installation depth of the wall box is sufficient for the relay
Confirm compatibility with your existing push-button wiring configuration
For optimal performance and longevity, ensure that the electrical connections are tightened securely and that the device is protected from extreme temperature fluctuations. Regularly inspect the push-button contacts to maintain reliable signal transmission.
