LightLEEDer UL924 Relay Bypass Output Module

Model: RBOM

The UL924 Relay Bypass Output Module (RBOM) is designed  for controlling lighting fixtures that are used as normal and emergency loads. The RBOM operates as a standard output module, but in the event normal power is lost, it forces the selected emergency lighting load relays ON, and bypasses all control in the panel. Each RBOM has 8 R-40 relay outputs, and selectable jumpers that can be set to "Force On", "Force Off", or "No Change" from the current state. The module is provided with a test switch for testing the emergency function, along with connectors for an external switch and status LED for an external optional switch station. An optional UL924 Phase Monitor Module is also available for monitoring more than local power phase, along with high voltage dividers to separate Emergency and Normal power in the panel.
