Honeywell – HGRL2-LF L-Series Second Generation Low Frequency Compact Wall Sounder

System Sensor L-Series and L-Series with LED platform offer the most versatile and easy-to-use line of Low Frequency Sounders and Sounder Strobes in the industry with lower current draw and modern aesthetics. They are designed to address the NFPA 72 sleeping space requirements that require a low frequency notification appliance that operates within frequency range of 520 Hz ± 10% and is of a square wave tone.

Flexible design options meet virtually any application requirement: wall or ceiling mount, red or white color choices, bezel kits for alternate markings and languages, and LED color lenses for distinctive visual signaling.

The L-Series and L-Series with LED appliances are developed to simplify installation. All devices feature plug-in designs with minimal intrusion into the back box, making installations fast and foolproof while virtually eliminating costly and time-consuming ground faults. The universal mounting plate includes an onboard shorting spring, so installers can test wiring continuity before the device is installed.

In addition, the System Sensor L-Series with LED notification appliances offer a new diagnostic test point feature that allows you to measure device voltage with a digital voltage meter (DVM) without removing the appliance from the wall or ceiling. The DVM test points are discreetly located on the face of the notification appliance, which enables faster troubleshooting and end-of-line (EOL) voltage checks while greatly reducing the risk of misplacing or damaging appliances during troubleshooting.
