ELPA 540 APP BN Staircase Time Switch: Compact, decentralized flush-mounted solution for limited space.
Limited space in the flush-mounted box, tight deadlines on the construction site, and complex retrofitting? The ELPA 540 APP BN offers electrical installers a compact, intelligent solution for staircase lighting control. This miniature staircase lighting timer is installed directly inside the flush-mounted box, requires no central control unit, and can be conveniently configured via an app.
Retrofitting staircase lighting control without major installation effort
When modernizing residential buildings, electricians often face the same challenges:
- limited space in existing installations
- tight schedules
- high demands on comfort and energy efficiency
The ELPA 540 APP BN was developed specifically to meet these requirements. The compact staircase light timer brings modern lighting control functions directly into the flush-mounted box and reduces installation effort to a minimum.
Benefits for electricians
No additional wiring required
No extensive renovation work
Installation directly in the flush-mounted box
Compact size: Dimensions of just 32.7 × 26.6 × 9.6 mm
Quick commissioning
Configuration is transmitted to all ELPAs via the Bluetooth Mesh network
High flexibility for new construction and retrofitting
Silent switching without an audible click
Continue using existing switches
A particular advantage for retrofitting: The existing installation can be used if a neutral wire is available. Even existing two-way connections can be used in conjunction with the ELPA 540 APP BN by rewiring them accordingly. And best of all: Switches do not need to be replaced with push to make switches!
This allows for quick and cost-effective modernizations without having to fundamentally alter the existing installation
Additional benefit: Fan control in restroom areas
In addition to classic stairwell lighting control, the ELPA 540 APP BN is also suitable for retrofitting fan controls in restroom areas. Installation takes place directly behind switches or push buttons. Fans without integrated time control or automatic delay, in particular, benefit from this solution.
Possible operating modes:
- Fan runs for the lighting duration
- Fan runs for the lighting duration and additionally for a defined time delay
- The time delay starts after the light is turned off
Bluetooth Mesh for flexible building solutions
The ELPA 540 APP BN communicates via a Bluetooth Mesh network. Multiple devices can be connected to a shared network. The configuration of a connected device is automatically transferred to all other ELPA 540 APP BN units. A central control unit in the control cabinet is not required.
This offers significant advantages:
Scalable installation
High reliability
No central control required
Easy expansion of existing systems
Safety note: If an ELPA 540 APP BN is integrated into the mesh network, no other devices from the 540 series may be integrated into the network! The lighting settings in the stairwell are thus tamper-proof.
Tamper-proof configuration via app
Configuration is performed exclusively via the ELPA app. This allows important parameters such as lighting duration, switch-off pre-warning, or time delays to be securely set. Residents continue to operate the lighting via the existing switches or push buttons but do not have access to the settings.
If only a single ELPA 540 APP BN is installed, the device can also be operated with the factory settings. The app is then not strictly necessary.
The ELPA 540 APP BN is the ideal solution for electricians who want to implement staircase lighting controls quickly, cost-effectively, and without extensive modifications. Thanks to its compact design, Bluetooth Mesh communication, app-based configuration, and the ability to reuse existing switches, the Mini Staircase Light Timer is suitable for both new construction and renovation projects. It reduces installation effort while providing greater convenience and energy efficiency for operators and residents.
