DESCRIPTION

The 2GIG-SMKT2-345 is a photoelectric smoke alarm with a built-in transmitter
designed for use with the 2GIG-CNTRL-345 security 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 fi xed
135° temperature and rate-of-rise heat sensor that will send an alarm signal
based on temperature detected.

BUILT-IN WIRELESS TRANSMITTER

The smoke alarm can send three different wireless signals to the alarm Control
Panel: alarm, low battery, and status.

Every hour, the smoke alarm sends a status transmission to the Control Panel.
The hourly signal updates the Control Panel with the smoke alarm’s condition.
By monitoring status transmissions, the Control Panel can determine that the
smoke alarm is still operational in the installation and if it has a low battery.

The Control Panel must be programmed to the transmitter’s serial
number before system testing and operation. Refer to the Control Panel’s

instructions for details on programming.

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 fi rmly into place.

• IMPORTANT: The unit cannot be attached to the base if no batteries
are installed.

PROGRAM SMOKE ALARM INTO THE CONTROL PANEL

Before testing the smoke alarm, the internal wireless transmitter must be
programmed into the Control Panel.

1. Refer to the Control Panel’s instructions to prepare the receiver to accept
the smoke alarm’s serial number.

2. Press the smoke alarm’s TEST/SILENCE button for 4 seconds. The
smoke alarm will perform a sounder test, a sensitivity test, and send a
test signal to the Control Panel.

3. Verify that the signal was received by the Control Panel and that the
sensor was entered into the system.

4. Exit Control Panel programming before testing the smoke alarm.

SMOKE TEST

Units should be tested in place annually using one of the following methods:

A. Use Smoke! in a can® and follow directions on the can.

B. Hold a smoldering punk or cotton wick close to the unit and gently direct

the smoke into the smoke entry openings for 20 seconds or until an alarm
is indicated.

The smoke alarm LED should stay on and the sounder should emit a temporal
three pattern, and an alarm should be indicated at the Control Panel. Disarm
the system to reset the Control Panel alarm. Be sure to extinguish the

smoke source after testing!

SILENCE THE ALARM

Press the TEST/SILENCE button to silence the sounder during an alarm. After
a few minutes, the sounder and alarm resume if smoke is still present.

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 ??????) 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.

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.
