Description

The L-Series offers the most versatile and easy-to-use line of low-frequency sounder and low-frequency sounder strobes in the industry. With red plastic housings, listed for wall mounting, System Sensor HRL-LF Low Frequency can meet virtually any application requirement.

The low-frequency sounder and low-frequency sounder strobes were 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. Like the entire L-Series product line they include a variety of features that increase their application versatility while simplifying installation. Also, all devices feature plug-in designs with minimal intrusion into the backbox; making installations fast and foolproof while virtually eliminating costly and time-consuming ground faults.

To further simplify installation and protect devices from construction damage, System Sensor HRL-LF uses a universal mounting plate with an onboard shorting spring, so installers can test wiring continuity before the device is install. Installers can also easily adapt devices to a suit a wide range of application requirements using field-selectable candela settings, 24- volt operation, and a rotary switch for 520 Hz low frequency sounder tones.
