## Summary description

FF BIS-416 is a flush-mount bistable (latching) relay with two independent control circuits. Designed for installation in wall boxes, it switches and maintains output states without continuous coil power, enabling energy-efficient control of lighting, circuits or home-automation loads. Suitable for use in residential and commercial electrical installations where separate control channels are required.

## Long description

FF BIS-416 is a flush-mount bistable (latching) relay with two independent control circuits. Intended for installation in standard wall boxes, the device switches and maintains its output states without continuous coil power, reducing standby energy consumption. The compact module enables centralized control of two separate lighting or load circuits while preserving the last commanded state after power interruptions.
Advantages
The relay offers two fully independent channels in a single flush-mount module, allowing separate switching of different loads from one installation point. As a bistable device it does not require continuous power to hold outputs, which lowers energy use and heat generation. Its design is compatible with common wall-box mounting standards and fits behind switches or in distribution points. The electrical contacts are intended for switching lighting and similar resistive or lightly inductive loads, enabling clean integration into residential and commercial wiring.
Suitable for
Switching and latching of residential lighting circuits
Control of separate lighting zones or groups from a shared mounting location
Integration into home automation systems requiring retained output state after power loss
Switching of small motors, HVAC control circuits or other low-power loads within rated limits
Key specifications
Flush-mount bistable relay with two independent control channels
Retains output state without continuous coil power (latching behavior)
Designed for installation inside standard wall mounting boxes
Electrical contacts suitable for lighting and similar resistive/low-inductive loads
Compact module size to fit behind switches or inside distribution enclosures
How to use
Install the module in a compatible wall box behind the control switches or inside a distribution enclosure, following local electrical codes and safety practices. Connect supply and load conductors to the relay terminals according to the wiring diagram provided by the installer or system documentation, ensuring each control circuit is wired independently if separate switching is required. Operate each channel via the connected switch, pushbutton, or control input; the relay will toggle and retain the last state until a subsequent command. Verify proper load ratings and observe polarity and grounding standards during installation.
Usage recommendations
Use the relay within the specified current and voltage ratings for lighting and small loads; avoid connecting loads that exceed the contact ratings or present high inrush currents without appropriate protection. For integration into automation systems, ensure control inputs and wiring follow the installer’s wiring diagram and comply with local regulations.
