With white and red plastic housings, listed for wall and ceiling mounting, L-Series 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.\u003c\/p\u003e\n\u003cp\u003eLike the entire L-Series product line they include a variety of features that increase their application versatility while simplifying 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. To further simplify installation and protect devices from construction damage, L-Series uses a universal mounting plate with an onboard shorting spring, so installers can test wiring continuity before the device is installed.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eMain Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e520 Hz ± 10% square wave tone, NFPA compliance\u003c\/li\u003e\n\u003cli\u003eFull candela range plus High\/Low tone options to optimize current draw for a wide variety of applications\u003c\/li\u003e\n\u003cli\u003eCompact, standard, and round ceiling options\u003c\/li\u003e\n\u003cli\u003eField-selectable candela settings.
