Optional Features
This Series includes a wide range of options, as shown in the Product
Selection Guide (Diagram 9) on back page. These options include a
built in sounder, an auxiliary relay, an integral heat detector, and an
isolated heat detector, to meet almost any application.
Self-Diagnostics Includes Automatic
Sensitivity Testing
Eachdetector in theSeriescontinually monitorsitsown sensitivity and
operational status. Once a day it performs a full diagnostic test that
includes dynamically testing the sensing chamber and internal elec-
tronics. If a detector drifts out of its UL Listed sensitivity range or fails
internal diagnostics, the alarm LED will flash once every second to
indicate trouble. This meets NFPA 72 field sensitivity testing require-
ments without the need for external meters.
NOTE: Connect to a power supply that will not automatically reset.
Since the self-diagnostics only indicate trouble after 27 hours, if the
power supply automatically resets every 24 hours the self-diagnostic
indication will never be signaled. (The smoke detector will still signal
alarm correctly.)
INSTALLATION
This Series of detectors mount to standard single-gang electrical
boxes, four-inch octagonal or four-inch square electrical boxes, or on
WIREMOLD No. 5739 fixture boxes. These detectors may also be
mounted directly to walls or ceilings where local codes/jurisdictions
permit.
First, pull wire through the electrical box and connect to the plug-in
terminal block supplied, one wire per terminal (see Diagrams 1, 2 and
3). Second, dress wiring neatly and snap the terminal block into the
back of the detector. Note: The detector cover must be closed com-
pletely, to support the circuit board, while installing the terminal block.

All ESL smoke detectors are shipped with a plastic dust cover for use
inareaswhereconstruction is on-going.Smokedetectorswillnotwork
with the dust cover in place. Remove the dust cover when installation
is completed, prior to testing.
Smoke Detector Placement and Spacing

centeroftheroomorhallwheneverpossible,ormorethan4inches(100
mm) from any wall. When the detector is wall mounted, the top of the
detector should be 4 to 12 inches (100-300 mm) from the ceiling (see
Diagram 4). Refer to NFPA 72 for further mounting instructions.
Whenmorethanonedetectorisrequired,spacingof30feet(9.1meters)
may be used as a guide on smooth ceilings (as defined in NFPA 72).
Other spacing may be used depending on ceiling height, high air
movement, and other conditions or response requirements.
Low Temperature Output Models (CLT, CSLT Models)
Thesemodels havea separate relayoutput thatwill be energizedwhen
the ambient temperature around the detectors falls to approximately
43°F.Note:thisdetectorcontinuestohavethesameoperatingtempera-

Where NOT To Place Detectors
One of the major causes of nuisance alarms is improper placement of
detectors.Avoidlocatingdetectorstooclosetokitchensorwoodstoves,
where smoke can be generated. Garages and furnace rooms are also
poor locations, due to exhaust fumes. Placing detectors too close to
bathroomscancauseproblemsfromsteamybathsorshowers.Alsodo
not install detectors where normal ambient temperature can be over
100°F(37.8°C),suchas attics. Referto NFPA72 formore information.
Supervision of System Wiring
Power wiring in four-wire systems is required by NFPA 72 to be
supervised.Thisisaccomplishedbyinstallingapowersupervisionrelay
attheend ofthedetectorpowercircuit. Thecontactsof thesupervision
relayarewiredinserieswiththesystem’salarminitiatingcircuit,andare
closedwhenenergized(seeDiagram3). Abreak inthedetectorpower
circuit or a loss of power de-energizes the power supervision relay,
opening the contacts and causing a trouble annunciation at the fire
alarm control unit.
ESL Models 204-6 V and 204-12/24 V are relays UL Listed for 4-wire
powersupervision. ESLModel204-12/24V CAN is arelayULCListed
for 4-wire power supervision. Models 449/448CTE, 449CSTE, and
449CSSTE are smoke detectors with a built-in end-of-line power
supervision relay, and can be used to supervise a circuit in place of a
powersupervision relay. The449CTE, 449CSTE, and449CSSTE will
also automatically send a trouble signal to the control panel whenever
thedetector needs maintenance. Proceed with sensitivity testing on all
detectors as outlined on next page.

NOTE: Positive air pressure from wire openings, conduit, mounting boxes,
irregular mounting surfaces, or plenums causing air movement through
and away from the detector may prevent proper operation. Seal all
openings causing unwanted air flow using UL Listed expanding foam or
Duxseal.
