Every Lomar device is managed via the CAN-bus protocol from a single department computer. The hospital's medical and technical staff can monitor every piece of equipment, including diagnostics and operation. All bedheads in a department can be centrally managed by setting maximum and minimum values for direct and indirect lighting, avoiding having all devices at maximum output. All lights can be turned off simultaneously via a software command, and everything happens instantly. Nightlight settings can be set to any desired level by automatically entering an operating time during which all devices simultaneously switch to night mode. Therefore, there are no timer systems or external wiring to install. If necessary, a healthcare worker can independently switch the bedhead from night to day mode, and once completed, the bedhead returns to its previously set state.
