SENSITIVITY TEST

1. Press and hold the TEST/SILENCE button for 4 seconds. Once the test

starts, the smoke alarm LED ﬂ ashes 1 to 9 times.

2. Count the number of LED ﬂ ashes and use the following table to determine

if any action is necessary.

After the LED ﬂ ashes, 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.

WHEN TO REPLACE THE BATTERIES

When the batteries are low, the unit extinguishes 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

counterclockwise 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 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 230802) as follows:

1. To remove the unit from the mounting base, grasp the unit and turn it

counterclockwise approximately 15 degrees.

2. Remove the batteries.

3. Slide a ﬂ at-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.

5. Blow out or use a soft-bristled brush to remove all dust and dirt from the

optical base.

6. Line the new smoke chamber up with the optical base by lining up the

arrows on the optical chamber to the latches on the optical base. Ensure

that the LED cavity in the optical chamber is above the LED and snap the

optical chamber down into place.

7. To replace the alarm cap as follows:

• Line the alarm cap up with the unit.

• Insert the alarm cap into the unit and turn clockwise approximately 15

degrees. It should snap ﬁ rmly into place.

ACTION

Reset and rerun sensitivity test. If

the error persists, replace the unit.

Clean and reset the unit. Rerun

sensitivity test. If the error persists,

replace the unit.

No action required

Verify that the optical chamber is

snapped down securely. Clean

the unit and replace the optical

chamber.

8. Observing proper polarity, replace the batteries and the battery

compartment cover.

9. Reattach the unit to its mounting base. See Installation , Step 6.

10. Test the unit sensitivity.

MAINTENANCE

The units are designed for easy ﬁ eld service and maintenance. When installed

and used properly, they require minimal maintenance.

The unit should be tested weekly.

When a unit requires maintenance, it extinguishes its LED and stops sending

supervisory signals to the alarm Control Panel.

If the Control Panel indicates supervisory trouble for the smoke alarm, perform

the sensitivity test and follow the recommended actions.
