AT&T Model SW-ATT-SMKT SMOKE ALARM
DESCRIPTION
The SW-ATT-SMKT is a photoelectric smoke alarm
with a built-in transmitter designed for use with the
ATT Digital Life Controller system. When smoke is
detected, the alarm sounds a loud local alarm. Twenty
seconds after the local alarm sounds, the built-in
transmitter sends a digitally coded wireless signal to
the Control Panel. The wireless signal will be repeated
every 20 seconds as long as smoke is still present. In
addition to the photoelectric detector, the unit
contains an integrated fixed 135° temperature and
rate-of-rise heat sensor that will send an alarm signal
based on temperature detected.
INSTALLATION
1. Slide the battery compartment cover away from the
unit to unsnap it and lift it off. See Figure 2.
2. Observing proper polarity, insert the two 3V lithium
batteries supplied into the alarm battery
compartment and replace the battery cover.
3. Remove the red plastic dust cover from the unit.
4. Refer to Page 3 for selecting a proper location for
the smoke alarm.
5. Using the two screws and anchors provided, mount
the base.
6. Attach the unit to the base as follows:
• Line up the raised alignment tab on the lip of the
unit with the alignment arrow on the base. See Figure
3.
• Insert the unit into the base and turn clockwise
approximately 15 degrees. It should snap firmly into
place.
IMPORTANT: The unit cannot be attached to the
base if no batteries are installed.
DISCOVER AND REGISTER THE SMOKE
DETECTOR
Reference Section Error! Reference
source not found., “Enter Discovery
Mode for Device Detection” for
instructions on entering the discovery
mode.
Click on the Start Discovery button to
enter the discovery mode on the DLC.
Enroll the Smoke Detector by pressing
and holding the test button for a
minimum of two (2) seconds.
Verify that the device appears on the
“Device Setup” page along with its
unique device ID.
SENSITIVITY TEST
1. Press and hold the TEST/SILENCE button for 4 seconds. Once the test starts, the smoke alarm LED flashes 1 to 9
times.
2. Count the number of LED flashes and use the following table to determine if any action is necessary.
FLASHES INDICATION ACTION
0-1 Unserviceable hardware fault. Reset and rerun sensitivity test. If
the error persists, replace the unit.
2-3 Unit is becoming insensitive. Clean and reset the unit. Rerun sensitivity test. If the error persists, replace the
unit.
4-7 Unit is within normal sensitivity range No action required
8-9 Unit is becoming too sensitive. Verify that the optical chamber is
snapped down securely. Clean the unit and replace the optical chamber.
After the LED flashes, if the sensitivity is within limits and all other tests pass,
the unit goes into alarm and resets after 7 seconds. If the sensitivity is not
within limits, or an unserviceable hardware fault has been detected, the unit
LED extinguishes until the unit is serviced.
LED FUNCTIONS
Flashing — Flashes every 9 seconds to indicate normal operation.
On — Detects smoke
Off — Trouble or maintenance is required.
Case Tamper Detection
Removing the cover of the SW-ATT-SMKT will cause the integral transmitter to send a case tamper report to the Digital Life
Controller. This tamper condition will remain on the system until the case cover is installed and the integral transmitter sends a
tamper restore to the Digital Life Controller.
WHEN TO REPLACE THE BATTERIES
When the batteries are low; the integral transmitter will send a low battery report to the Digital Life Controller,
extinguish its LED and chirps every 45 seconds until the batteries are replaced. The low battery trouble chirps can be
silenced for 24 hours by pressing the TEST/SILENCE button. Battery life is a minimum of one year, and varies depending
on how often the unit is tested.
REPLACING THE BATTERIES
Use only 3V lithium batteries listed on the battery compartment cover.
1. Remove the unit from the mounting base, grasp the unit and turn it
Counter clockwise approximately 15 degrees.
2. Slide the battery compartment cover away from the smoke alarm to
unsnap it and lift it off. See Figure 2.
3. Remove the batteries and dispose of them properly.
4. Observing correct polarity, insert two new CR123A 3V lithium batteries into the battery compartment
and replace the cover.
5. Reattach the unit to the mounting base. See Installation, Step 6.
6. Test the system.
CLEANING
Clean the cover with a dry or damp (water) cloth as needed to keep it free from dust and dirt.
When necessary, clean the interior and replace the optical chamber (part number ??????) as follows:
1. To remove the unit from the mounting base, grasp the unit and turn it Counter-clockwise approximately 15
degrees.
2. Remove the batteries.
3. Slide a flat-blade screwdriver in the slot on the alarm cap and gently push the handle down to pry the alarm cap
up and off. See Figure 4.
4. Squeeze the optical chamber where indicated and pull it up and away from the optical base and discard. See
Figure 5.
