ELK-6050 Wireless Smoke Detector
Maintenance
This 6050 Smoke Detector is designed for a service life of approximately
8 to 10 years. Even so, the following annual and random maintenance
tests are recommended:
Annual
- Smoke Detector Test - Locate and follow the section in
this manual titled: Full-Alarm Testing of the Smoke Alarm
Random
- Visually check for LED flashing every 16 seconds
- Perform a Detector Sensitivity Test
Detector Sensitivity Test
This test performs a manual diagnostic of the detector with the results
displayed via flashes of the Alarm/Status LED. To initiate this test:
A. Press and hold the detector Test button for 4 seconds. Once the
test starts, the alarm/status LED will flash 1 to 9 times.
B. Count the LED flashes and view the table below to determine the
results of the sensitivity test and any action required.
IMPORTANT:
If the sensitivity is within limits and all other tests pass, the detector will
go into full alarm mode after the LED flashes stop. This also causes the
Control to go into alarm. The detector will auto-reset after 7 seconds,
but the Control's alarm must be manually reset by entering a User Code.
If the sensitivity is not within limits, or an unserviceable hardware fault
is detected, the LED will remain OFF indicating that the Smoke Detector
must be serviced or possibly replaced.

MEANING
STEPS TO TAKE
1
Unserviceable hardware
fault
Reset smoke sensor alarm and rerun
the sensitivity test. If error persists,
replace smoke sensor.
2 - 3
Smoke sensor is becoming
insensitive
Clear smoke sensor, reset it, and rerun
the sensitivity test. If error persists,
replace smoke sensor.
4 - 7
Smoke sensor is within
normal sensitivity range.
None.
8 - 9
Smoke sensor is becoming
too sensitive
Verify smoke chamber is snapped down
securely. Clean smoke sensor and
replace the smoke chamber.
Cleaning the Smoke Detector
Clean the cover with a dry or slightly damp (water ONLY) cloth as needed
to keep it free from dust and dirt. When necessary, use the following
procedure to clean the interior of the detector and replace the optical
chamber (UTC part #211) as follows:
A. Notify the Central Monitoring Station prior to cleaning or testing.
B. Remove the detector from its mounting base. This will generate a Fire
Trouble condition on the Control annunciated by the keypad.
To temporarily silence the trouble condition press the " * " key on the
keypad.
C. Remove the battery cover and then remove both batteries.
D. Slide a flat-blade screwdriver in the alarm cap slot. Gently push the
handle down to pry the cap up and off. See figure above.
E. Squeeze the black optical chamber cap at the arrows indicated on
the top of it. Pull it up and away from the optical base and discard.
F. Carefully blow out all dust and dirt from the optical base. A soft-
bristled brush may also be utilized.
G. Align the latches on the optical base with the arrows on the NEW
optical chamber and snap it down into place.
H. Replace the detector cap by aligning the four protrusion with the
notches in the detector. Then insert the cap and turn clockwise about
15 degrees. The cap should snap firmly into place.
I.
Insert the batteries into the detector using the proper polarity, then
replace the battery compartment cover.
J. Reattach the detector to its mounting base.
K. To clear the silenced trouble condition go to the keypad and enter a
valid User Code.
L. Run the Detector Sensitivity test.
