449CTE SERIES
Self-Diagnostic,
Four-Wire,
Photoelectric Smoke
Detectors
Model number: 449CTE
• Automatically reports trouble
when dirty
• Integral power supervision
• Intelligent, self-diagnostic
• Field replaceable optical chamber
• Low-profile design
• Plug-in terminal block
• Advanced false alarm immunity
The ESL 449CTE is a self-diagnostic, four-wire
smoke detector with an extra relay that provides
two added functions: power supervision and sensitivity status. The 449CTE Supervisory relay is normally
energized, and will trip with loss of power, providing
power supervision. The relay also trips if the
detector's self-diagnostics detect an electronic
failure, or if the detector is outside the UL listed
sensitivity range for more than one day. This results
in a trouble condition at the control panel, providing
early warning that the detector needs cleaning or
maintenance. This 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 allows latching of the
alarm for either smoke or heat.

ESL 449CTE Series Smoke Detectors
Architectural and Engineering Specifications
The ESL 449CTE Series is a low-profile, self-diagnostic,
four-wire smoke detector with an extra relay that provides
two added functions: power supervision and sensitivity
status. The 449CTE works on the light scattering principle.
A pulsed infrared light-emitting diode serves as the light
source, and a high-speed photo-diode 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 then 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.
The optical sensing chamber is field replaceable, allowing
quick and easy cleaning and maintenance.
The very low profile 449 Series detectors are equipped with
a hinged cover, a concealed tamper-resistant latch, and
insect screens.
All wiring terminates in plug-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.
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.
