This unique, patented technology meets NFPA 72 field sensitivity testing requirements without the need for external meters. Additional diagnostic information is activated by applying a magnet near the detector's integral reed switch. This initiates a self-diagnostic routine and provides visual indication of sensitivity level, or if service is required. This series is easily cleaned by simply replacing ESL’s proprietary field-replaceable optical chamber. All models are designed to reduce false alarms from dust, insects, RFI, and external light. An integral combination rate-of-rise and fixed 135°F (57°C), 50-foot rated, heat sensor is available with all “T” model detectors (see selection guide), allowing latching of the alarm for either smoke or heat. The 449CSRH includes an isolated alarm output for heat and activates an internal non-latching sounder (local alarm) for smoke, making it ideal for motel/hotel and dormitory rooms where smoking is permitted.

Architectural and Engineering Specifications The ESL 449 Series low-profile, self-diagnostic, four-wire smoke detectors work on the light scattering principle. A pulsed infrared light-emitting diode serves as the light source, and a high-speed photodiode as the sensing element. When the amount of light reflected onto the photodiode reaches the sensitivity setting, the smoke sampling rate increases. Three (3) successive smoke sensings above the sensitivity setting are required to sound an alarm. This design has superior protection against false alarms caused by dust, insects, RF and ambient-light. A confirmed alarm causes the normally flashing power indicator LED to light continuously and the alarm relay to operate. A trouble indication is automatically displayed by flashing the LED every second. This meets NFPA 72 field sensitivity testing requirements. An internal 85 dB horn (available in “S” models) emits a temporal 3 when the detector alarms and a steady tone when power polarity is reversed.

Models with auxiliary relays are approved for releasing service. This low profile product is equipped with a hinged cover, a concealed tamper-resistant latch, and insect screens. Wiring terminates in plug-in, clamp-type screw terminals. Detectors mount to a standard single-gang electrical box, a four-inch octagonal, four-inch square electrical box, or WIREMOLD 5739 fixture box. Smoke Detector Spacing On smooth ceilings (as defined in NFPA 72), spacing of 30 feet (9.1 meters) may be used as a guide. Other spacing may be used depending on ceiling height, high air movement, and other conditions or response requirements. - CST..........................................................................40mA - CSRT, CSRH, CSTE................................................51mA Typical avg. polarity reverse current - CST, CSRT, CSTE, and CSRH................................10mA Sounder specifications.........................................85 dB at 10' Heat detector specifications - fixed temperature..................................... 135°F (57.2°C) - rate of rise....15°F/min. & >105°F (8.3°C/min. & >40.6°C) Auxiliary relay contacts2A @ 28 VDC or 120 VAC (resistive) Alarm contacts........................ 500 mA @ 36 VDC (resistive) Field wiring size..................................................14 - 24 AWG Packaging.......................10 detectors are packed in a carton Color....................................................white cover/white base with UV inhibitor to prevent yellowing Listing..............................
