This section displays a possible configuration for DALI control based emergency lighting setup using Casambi -network luminaires. Assumptions for this section are, that the Casambi network is set up normally and contains the luminaires to be used as emergency luminaires. Luminaires to be used are emergency luminaires and have the relevant capabilities.
In our example only Emergency luminaires are controlled through DALI gateway, and we are reflecting that in the Control priority settings.
The controlling DALI system has to be configured accordingly; if Casambi system is the primary lighting control system, DALI system settings have to be configured not to cancel/fight against Casambi control commands.
Recommended initial settings:
Please note: Presented recommendations are a meant to be a starting point for your own settings, this means that your application may require changes depending on for example DATA frequency needs etc.
Gateway parameters:
Control scope: Select the scene, which contains the desired emergency (capable) luminaires. Here our scene is called “Emergency Luminaires”.
Control priority: There our example is Lowest-priority automation. You can explore different control priority options, but Lowest-priority automation in Emergency luminaires only -setup allows the Casambi system to have priority on the lighting level, but still allows the Emergency system to control lights when needed. This setting also avoids accidental control of luminaires from the DALI master side. Please note: The control priority of the DALI master has to be set accordingly, and cannot prioritized higher than the Casambi system!
DALI Emergency mode: Enabling this setting allows DALI controller to interact with emergency luminaires (DALI DT1) that are managed within the Casambi network.
Parameters:
Unless absolutely required by the controlling DALI system or other integrated system, it is always beneficial to slow down the update rates to as slow as possible. This reduces the loading of the Casambi mesh and thru that increases the performance of the network. Also bandwith is reserved for node quantity and / or sensor operations.
Below is a good starting point for timely parameters.
Please note: This is a recommendation starting point for settings when creating DALI emergency light configuration, the settings you need may differ based on the controlling system needs and depend on other network configuration.
