System Sensor PC2RL-LF. Low Frequency Ceiling Horn Strobe.

The System Sensor PC2RL-LF L-Series indoor selectable output low-frequency sounder strobe provides effective audible and visual notification for modern fire alarm systems. From the moment it activates, this device delivers clear alerts that help occupants recognize emergency conditions quickly. Because it uses low-frequency signaling, it improves alarm awareness in sleeping areas and other critical indoor spaces. As a result, it is a trusted solution for commercial and institutional fire alarm installations that require code compliance and dependable performance.

Low Frequency Audible Performance
The PC2RL-LF sounder strobe operates at a low frequency designed to improve audibility in areas where standard tones may not perform as well. Therefore, it supports safer evacuation by helping occupants hear alarms more clearly. In addition, selectable output settings allow installers to adjust sound levels based on room size and application needs. Because of this flexibility, the device supports consistent alerting across different indoor environments.

High-Visibility Strobe Notification
Along with audible signaling, this device includes a bright strobe for visual notification. As a result, it enhances awareness for occupants who rely on visual cues. Moreover, the strobe output supports accessibility requirements and improves overall life safety coverage. This combination of sound and light helps ensure alerts reach a wide range of building occupants.

Ceiling-Mount Design and Identification
The ceiling-mount design allows for clean and effective placement in corridors, rooms, and open spaces. Additionally, the red housing with clear “FIRE” marking improves visibility and device recognition during emergencies. Because of its low-profile appearance, the unit blends well into interior spaces while remaining easy to identify when activated.

System Integration and Wiring
The System Sensor PC2RL-LF L-Series sounder strobe uses a 2-wire connection, which simplifies installation and system layout. Therefore, installers can integrate it into compatible fire alarm systems with less complexity. This wiring approach also supports efficient upgrades and retrofits, which helps reduce installation time and labor costs.

Typical Indoor Applications
This low-frequency sounder strobe is well-suited for hotels, dormitories, healthcare facilities, apartments, and office buildings. It also performs effectively in corridors, common areas, and sleeping rooms. Because it is designed for indoor use, it delivers reliable performance in controlled environments where consistent notification is essential.
