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

<br />Selection Guide
<br />
<br />The proprietary optical sensing chamber is field replaceable, allowing
<br />quick and easy cleaning and maintenance,
<br />Models with auxiliary relays are approved for releasing service.
<br />This low profile product is equipped with a hinged cover, a concealed
<br />tamper-resistant latch, and insect screens,
<br />Wiring terminates in plug-in, clamp-type screw terminals. Detectors
<br />mount to a standard single-gang electrical box, a four-inch octago-
<br />nal, four-inch square electrical box, or WIREMOLD 5739 fixture box.
<br />
<br />Smoke Detector Spacing
<br />On smooth ceilings (as defined in NFPA 72), spacing of 30 feet (9,1 meters)
<br />may be used as a guide, Other spacing may be used depending on ceiling
<br />height, high air movement, and other conditions or response requirements.

<br />H Isolated Fixed Temp. Isolated fixed 1350F (570C) and rate of rise heat detector, independently trips the LED and alann
<br /> and Rate of Rise Heat output, Smoke detector activates intemal sounder (local alann) and auxiliary relay, but
<br /> Detector does not latch, Approved as both single station smoke alann and system heat detector, Ideal for
<br /> hotel, motel and donnitory rooms where smoking is allowed.
<br />R Auxiliary Relay Used to activate other devices such as elevator recall; door holders, strobes, etc. Listed for
<br /> releasing service,
<br />S Built-in Sounder 85dB built-in sounder alarms when smoke is detected or when power wiring polarity is reversed.
<br />SS Built-in Sounder with 85dB built-in sounder alarm when smoke is detected or when power wiring polarity is reversed,
<br /> Sensitivity Status Also, chirps every 5 minutes when unit goes outside the approved sensitivity range for more
<br /> Output than one day, Resetting detector will silence chirp for one day, until unit is restored to
<br /> proper sensitivity,
<br />T Integrated Fixed Integrated Fixed 1350F (570C) temperature and rate of rise heat detector offers double
<br /> Temp, and Rate of Either heat detector or smoke detector can trip and latch LED and alann protection.
<br /> Rise Heat Detector relay outputs,
<br />L Low temperature Separate relay output that energizes when temperature around detector reaches 430F
<br /> output ::!: 50F (6.1 oC ::!: 2,8OC)
<br />E Built-in end of line Relay is nonnally energized and will trip with loss of power. Can also provide notification
<br /> power supervision relay when detector needs maintenance,
