• In dead air spaces at the top of a peaked ceiling or wall/ ceiling
intersect. Dead air may prevent smoke from reaching a smoke sensor.
• Near fluorescent light fixtures. Install smoke sensors at least 3m (10
feet) away from fluorescent light fixtures.
• Between protruding ceiling structures such as beams or walls which
can create dead air spaces and may prohibit smoke from reaching the
detector.
Caution: All sensors are subject to possible compromise or failure-to-warn
for a variety of reasons. For example: Smoke sensors cannot detect smoke
in chimneys, walls, roofs, or smoke blocked by a closed door; sensors may
not detect smoke on other levels of the building; sensors may not warn in
time when fires are caused by smoking in bed, explosions, improper
storage of flammables, overloaded electrical circuits, or other hazardous
conditions.
3 Test the EE1243
Caution: To avoid a fire department dispatch, contact the central
monitoring station or, if possible, put the system into sensor test mode.
There are two ways to test the EE1243 smoke detector sensor. The
sensitivity test should be performed every week; the smoke test should be
performed at least once a year. Both tests activate the alarm sounder and
send alarm signals.
The EE1243 should also be tested after initial registration, as well as each
time the smoke chamber is changed or the batteries are replaced.
3.1 Smoke Test
1. Use aerosol simulated smoke, such as ESL Smoke! In a Can® (ESL
Part No. SM-200) to perform the smoke test.
The LED will remain on while the built-in transmitter sends an alarm signal,
and the sensor will produce a three-beep pattern.
2. Press the test/silence button to end the test.
The sensor automatically resets when smoke is no longer present. A
sensor that fails to activate may require cleaning. If a sensor still fails to
activate after cleaning, return the unit for service.
3.2 Sensitivity Test
1. Press and hold the test button for four seconds, then release it. The
LED will flash corresponding to the sensor’s sensitivity.
During this test, the control panel, serial receiver or network coordinator
should receive an alarm, followed a few seconds later by a restoral.
If the control device fails to respond, it is possible the EE1243 failed to
reset properly when the batteries were installed. To force a reset, remove
the batteries from the EE1243 for a least 30 seconds, reinstall them, press
the reset button, then retest as described above.
4 Clean the EE1243
Clean the sensor cover with a dry or damp cloth as needed to keep it free
from dust and dirt. Clean the sensor interior and replace the optical
chamber at least once each year. Use only ESL model 211 optical
chambers for replacement. To clean the sensor chamber:
1. Remove the sensor body from the mounting base.
2. Remove the batteries.
3. Slide a flat-blade screwdriver in the slot on the sensor cap and gently
push the handle down to pry the cap off.
4. Squeeze the optical chamber where indicated and pull it up and away
from the sensor. Discard.
5. Use a soft-bristled brush to remove dust and dirt from the smoke
chamber base.
6. Align the new optical chamber with the base and snap it down into
place.
7. Replace the sensor cap.
8. Reinstall the batteries.
9. Replace the battery cover.
10. Reattach the sensor to the mounting base.
Note: The base will not fit properly if the batteries are not installed.
11. Perform the sensitivity test.

Flashes Sensor Condition/Action
1 Self-diagnostics failure. Return sensor for service/
replacement.
2-3 Sensor is becoming insensitive. Clean the sensor (see
“Clean the EE1243”) and retest. If error persists, replace
sensor.
4-7 Sensor is within normal sensitivity range.
8-9 Sensor is becoming too sensitive. Verify that the smoke
chamber is snapped down securely. Clean the sensor and
retest.
