The selectable candela output lets installers configure each device for its specific location without stocking multiple part numbers, and the six tone options including temporal three, continuous, 2400Hz, mechanical, chime, and whoop cover the full range of code requirements and facility preferences. The HS-24WR operates on 24VDC from the fire alarm panel notification appliance circuit with minimal current draw and a consistent 1Hz flash rate.\u003c\/p\u003e\n\u003cp\u003eThe HS-24WR is part of the \u003ca href=\"\/collections\/potter\"\u003ePotter\u003c\/a\u003e HS-24 Series and ships with a standard 4-inch metal mounting plate featuring the Super-Slide bracket for fast installation and easy supervision testing access. The Checkmate Instant Voltage Verification feature lets technicians confirm proper wiring and voltage drop at the device without a multimeter, speeding commissioning and annual inspections across large notification appliance circuits. The tamperproof locking mechanism conceals mounting screws to prevent unauthorized removal, and the unit carries ANSI\/UL 464 and ANSI\/UL 1971 listings for fire protective signaling applications.\u003c\/p\u003e\n\u003ch3\u003eWhere the HS-24WR Fits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial office buildings and corporate campuses\u003c\/strong\u003e where the selectable 15 to 110 candela output configures each device for hallways, open offices, conference rooms, and lobbies without changing the part number, the six field-switchable tones allow different zones to use different alarm signals, and the minimal current draw supports more devices per notification appliance circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchools, universities, and institutional buildings\u003c\/strong\u003e where the Super-Slide mounting plate speeds annual NFPA testing by providing easy access for supervision verification, the Checkmate voltage verification eliminates the need for a multimeter at each device during commissioning, and the tamperproof locking mechanism prevents unauthorized removal in high-traffic corridors and stairwells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHealthcare facilities and assisted living environments\u003c\/strong\u003e where the six tone options allow each floor or wing to use a distinct alarm pattern for staff recognition, the low-profile housing fits into finished ceilings and walls without drawing attention, and the selectable candela range accommodates both small patient rooms and large common areas on the same notification appliance circuit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat the HS-24WR Delivers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Candela Output:\u003c\/strong\u003e Field-adjustable 15, 30, 60, 75, and 110 candela settings via selector switch.
