LightLEEDer UL924 Phase Monitor Module (PMM)
Overview
The UL924 Phase Monitor Module (PMM) is used in conjunction with the UL924 Relay Bypass Output Module, and controls the bypass operation if any of the monitored normal electrical phases loses power. It can be configured to monitor 2 or 3 phases. This module mounts in place of 2 R40 relays in the LightLEEDer panel. A test switch is provided to test this board, along with the UL924 Relay Bypass Output Modules in the panel. Auxiliary NO and NC dry contact outputs provided for signaling other devices and systems.
