500 Series Detector - 1

Conventional Fire Alarms Smoke Detectors 500 Series FIRE ALARMS Edwards 500 Series two-wire conventional photoelectric smoke detectors work on a light-scattering principle. A pulsed infrared light-emitting diode serves as the light source, and a high-speed photo diode as the sensing element. This design protects against nuisance alarms caused by dust, insects, RF interference, and ambient light. Built-in drift compensation allows the detector to automatically adjust its sensitivity over time as it becomes dirty. The 500 Series optical chamber is field replaceable. In the event of a confirmed alarm the LED will light continuously. The unit indicates trouble by flashing the LED every second. This meets the NFPA 72 field sensitivity testing requirements. Features and Specifications • elf-diagnostic capability continually S monitors operation • emote maintenance (CleanMe) reporting and R built-in drift compensation • Field-replaceable optical chamber • Low-profile design blends into the ceiling • Optional auxiliary functions include: - Integral sounder; 85dB @ 10ft. - Fixed/Rate-of-Rise heats • White color • Includes mounting base • perating temperature range: 32°F to 100°F O (0°C to 37°C) The 500 Series offers sounders in two-wire applications, specifically to meet residential code requirements. Units with built-in 85dBA sounders emit a temporal 3-3-3 tone pattern when in alarm and will emit a steady tone when the input power is reversed. All wiring terminates in clamp-type screw terminals. The detectors mount to a standard single-gang electrical box, a four-inch octagonal, four-inch square electrical box, or WIREMOLD No. 5739 fixture box.
