Alarm Ringer PATLITE LR7-BU
The PATLITE LR7-BU alarm ringer delivers a loud 90 dB audible alert in a compact silver housing (70 mm diameter, 53.5 mm depth). Designed for industrial environments, the unit is UL 508 and CSA-C22.2 No.14 certified and operates from a DC 24 V supply for reliable signaling.
The LR7-BU provides a high sound output (90 dB) in a small footprint, simplifying installation in confined locations. Its UL and CSA certifications confirm compliance with common industrial safety standards. The DC 24 V operation ensures compatibility with standard industrial DC power systems, and the silver finish offers neutral aesthetics suitable for many applications.
Mount the LR7-BU in a suitable panel cutout or on a flat surface so the sound can propagate without obstruction. Connect the unit to a DC 24 V supply following the manufacturer wiring diagram and observe polarity. Test the buzzer after installation to verify audibility and proper operation within the intended environment.
Install the device at a height and orientation that provide clear sound coverage for the target area; avoid enclosing the buzzer behind insulating materials. Ensure the supply voltage is a stable DC 24 V and perform periodic functional checks as part of routine safety maintenance.
