Lighting control panel PHASE LOSS SENSE

The Strand 120V/277V Phase Loss Sense Panel (PLSP) is a cETLus and UL924-listed power sensing device designed for single phase or three phase applications. This latest generation of the PLSP supports both 120V and 277V applications, monitoring normal power feeds and fire alarm control panels (FACPs), detecting outages and alerts. When a power loss or alert is detected, the PLSP signals the connected devices to enter their emergency state, ensuring that, upon a power loss, the entertainment luminaires, house lights, and other connected devices will come on to the desired emergency state. The PLSP offers three separate change-over contact outputs that can each be independently set to normally open or normally closed. Integrators can control up to 5 devices per output when daisy chained, including Strand power devices, Vision.Net controlled devices (via the 4-Port Digital I/O Module or 8-Port Digital Input Module), the Strand Emergency Bypass Switch, or even third-party contact closure devices. The PLSP also includes capabilities that ensure the system works as users expect both during normal operation and emergencies. The system includes variable delay timing with a field-configurable delay setting to prevent nuisance triggers, providing a more stable system and avoiding long system reboot times unnecessarily. For applications such as theatrical performances or dark rides at theme parks, the PLSP offers optional remote restore functionality that ensures that lights will not return to their previous “dark” state without manual intervention.
