System Sensor PC2RLED Ceiling-Mount LED Horn Strobe

The System Sensor PC2RLED is a commercial-grade, ceiling-mounted, two-wire LED horn strobe designed to provide audible and visual fire alarm notification in commercial and institutional buildings. Part of the System Sensor L-Series with LED, the PC2RLED combines a high-efficiency LED strobe, configurable electronic horn, red housing, clear lens, and FIRE marking in a single notification appliance. Featuring seven field-selectable candela settings of 15, 30, 75, 95, 115, 150, and 177 cd, the device provides flexible visible notification coverage for different ceiling-mounted applications. The integrated horn supports eight selectable tone and volume combinations, including temporal-three and continuous audible patterns, with sound output up to 87 dBA under the manufacturer's specified test conditions. Operating on regulated 24VDC with a 16-33V operating range, the PC2RLED incorporates low-current LED technology, System Sensor synchronization compatibility, and accessible digital voltage meter (DVM) test points. Its plug-in mounting design, universal mounting plate, and onboard wiring continuity shorting spring simplify installation and maintenance. UL/ULC listed for applicable fire alarm notification applications, the PC2RLED is suitable for offices, healthcare facilities, schools, hotels, warehouses, and other indoor commercial life-safety systems.

System Sensor PC2RLED L-Series LED Ceiling-Mount Fire Alarm Horn Strobe, Red

The System Sensor PC2RLED L-Series LED Horn Strobe provides integrated audible and visual fire alarm notification for commercial and institutional life-safety installations. Manufactured by Honeywell System Sensor, this two-wire, ceiling-mounted notification appliance combines an electronic alarm horn and energy-efficient LED strobe within a red housing featuring a clear lens and prominent FIRE identification. Its integrated design allows compatible fire alarm notification appliance circuits (NACs) to activate both audible and visible warning signals through a common two-wire connection. The PC2RLED offers seven selectable strobe intensity settings ranging from 15 to 177 candela, enabling fire alarm system designers to select the required light output according to the room dimensions, mounting location, and applicable notification requirements. The device also incorporates selectable audible patterns and volume settings to support different building notification strategies. Typical applications include commercial offices, educational buildings, hospitals, hotels, retail facilities, warehouses, and institutional properties requiring ceiling-mounted fire alarm horns and strobes. Compared with earlier xenon-based notification appliances, the L-Series LED platform provides reduced electrical current consumption across compatible candela settings, helping improve notification circuit design flexibility.

The PC2RLED features a high-efficiency LED strobe with field-selectable 15, 30, 75, 95, 115, 150, and 177 cd light output, providing a broad range of ceiling-mounted visual notification configurations. The strobe operates at one flash per second, while the integrated electronic horn supports eight combinations of audible tone and volume. Available selections include temporal-three and non-temporal patterns using standard and 3.1 kHz tones, each with high or low volume settings. Manufacturer-published sound output ratings range from approximately 79 to 87 dBA, depending on the selected horn pattern and volume setting. Electrical operation requires regulated 24VDC nominal power, with an approved operating voltage range of 16-33VDC. Combined horn-strobe current consumption varies by candela and sound selection, with the manufacturer's published maximum current values ranging from 35 mA at lower output settings to 190 mA for certain high-candela configurations. The circular ceiling-mounted housing measures approximately 6.83 inches (173.5 mm) in diameter and 2.07 inches (52.6 mm) deep, including the lens. Environmental specifications include an operating temperature range of 32 F to 120 F (0 C to 49 C) and relative humidity of 10-93% non-condensing. The appliance supports 12-18 AWG wiring and is designed for indoor fire alarm notification applications.

For fire alarm system integration, the System Sensor PC2RLED operates as a two-wire audible/visual notification appliance connected to a compatible fire alarm control panel or notification power supply. Its horn and strobe can be coordinated with other supported System Sensor notification devices through the System Sensor synchronization protocol, using a compatible UL-listed power supply, appropriately configured notification circuit, or System Sensor MDL3 synchronization module. Synchronization helps coordinate visual alarm flashes across multiple notification appliances and supports consistent audible notification patterns when the system is properly designed and programmed. The device's field-selectable candela, tone, and volume settings allow installers to configure notification performance according to approved fire alarm drawings and site-specific requirements without changing the appliance model. The L-Series with LED platform is designed for electrical compatibility with supported legacy System Sensor SpectrAlert, SpectrAlert Advance, and earlier L-Series notification appliances, facilitating qualifying retrofit projects and system expansions. The PC2RLED is identified in manufacturer documentation as a UL/ULC-listed notification appliance with applicable FM and California State Fire Marshal approvals. Its horn and strobe are evaluated under applicable ANSI/UL 464 and ANSI/UL 1638 notification appliance standards, with installation subject to NFPA 72 and the requirements of the local Authority Having Jurisdiction (AHJ).

Installation of the System Sensor PC2RLED ceiling-mounted LED horn strobe uses a manufacturer-designed plug-in architecture with a universal mounting plate that accommodates compatible electrical boxes. Supported mounting arrangements include 4-inch square electrical boxes, single-gang boxes, double-gang boxes, and 4-inch octagonal boxes when installed according to the manufacturer's approved mounting instructions. The mounting plate incorporates an onboard shorting spring that permits field wiring continuity checks before the notification appliance is attached, helping installers identify wiring problems during construction and commissioning. The plug-in design minimizes intrusion into the electrical back box and reduces direct handling of the appliance's electrical connections during mounting. The PC2RLED also features accessible digital voltage meter (DVM) diagnostic test points, allowing technicians to measure appliance voltage and perform end-of-line troubleshooting without removing the device from the ceiling. During installation, technicians select the required candela intensity, configure the horn's audible pattern and volume, verify the notification circuit's electrical capacity, and test synchronization and alarm activation. Optional System Sensor surface-mount accessories are available when a recessed mounting arrangement is unsuitable. The PC2RLED is the LED-based successor to the PC2RL ceiling horn strobe, while the PC2WLED provides a comparable white-housing configuration. Combining seven selectable candela settings, eight audible configurations, low-current LED technology, synchronized notification capability, and accessible diagnostic features, the PC2RLED provides a versatile fire alarm notification solution for indoor commercial and institutional ceiling installations.
