FCC ID: ZFH‐SMKT3345
Industry Canada ID: 9640A‐SMKT3345
2GIG’s Wireless Smoke/Heat/Freeze Alarm is a 3xAAA battery‐powered wireless alarm intended
for use in a 2GIG system. The alarm has a built‐in wireless transmitter, which communicates
with the 2GIG Control Panel. When smoke, excessive heat or cold is detected, the alarm sounds
a loud local alarm and the built‐in transmitter sends a signal to the Control Panel. This alarm is
designed to provide protection within a 35‐foot radius of the unit. The 2GIG‐SMTK3‐345 can
send alarm, tamper and battery condition messages to the Control Panel.
• Wireless Smoke/Heat Alarm
• Pack of screws and fixings
• 3 AAA Energizer E92 batteries (1.5 V1100mAh) or equivalent
The Wireless Smoke/Heat Alarm contains a sounder that generates the ASHI s3.41 temporal 3
pattern in an alarm condition.
In alarm, a message is also sent to the Control Panel and the alarm’s zone type and name are
displayed at the panel. During an alarm condition, pressing the alarm’s hush button silences the
sounder. Tricolored LED (red, yellow, green) and a sounder on the alarm provide local visual and
audible indication of the alarm’s status.
After power‐up has completed and the alarm is functioning normally, the green LED blinks every 12
Alarm Trouble: When the alarm has a general fault, the yellow LED blinks once every four seconds
and there is a chirp every 48 seconds. After 4 hours the 2GIG Control Panel displays a loss of
Alarm Dirty Feature: When the alarm has been contaminated, the yellow LED blinks once every 8
seconds and there is a chirp every 48 seconds. After 4 hours the 2GIG Control Panel displays a loss
of supervision message.
Low Battery Detection: The Wireless Smoke/Heat Alarm is powered by 3 AAA batteries. The alarm
regularly checks for a low battery. If a low battery is detected, the transmitter sends a low battery
message to the 2GIG Control Panel, that displays the alarm’s ID at low battery. In addition, the
yellow LED of the alarm blinks every 12 seconds. The alarm’s sounder chirps every 48 seconds
(yellow LED continues to blink) until the batteries are replaced. Pressing the hush button silences
the chirping for 12 hours if no other trouble conditions exist. Replace the batteries when the
chirping begins. Replace the old batteries with new ones.
If you are experiencing low battery issues, check to make sure that you have the correct batteries
installed (3 AAA Energizer E92).
Inserting and Replacing Batteries
1. Remove the alarm from its base by twisting the it counter‐clockwise. Remove and dispose of
the batteries according to your local regulations.
2. To ensure proper power‐down sequence, wait a minimum of 20 seconds before
inserting new batteries.
3. Insert 3 AAA Energizer E92 batteries in the battery compartment. Follow the polarity diagram
inside the compartment. If the batteries are inserted incorrectly, remove gently with a non‐
conductive tool and correctly reinsert.
4. Reinstall the alarm onto the mounting base by turning the alarm clockwise until the mating
5. After the power‐up sequence, the green LED should blink about once every 12 seconds to
indicate normal operation. If the batteries are not inserted correctly, the alarm will not operate
and the batteries may be damaged. If the alarm does not power‐up, check for correct battery
insertion and for fully charged batteries.
Constant exposure to high humidity may reduce battery life.

Before testing, put the panel into test mode so the central station is not notified to prevent
unwanted alarms. Testing the alarm activates an alarm sound and sends a signal to the Control
Panel. The test function cannot be used if the alarm has a trouble condition.
Test alarm sounder, LEDs and transmitter
1.Hold the Test button for 4 beeps (approximately 6 seconds).
2.Release the Test button.
3.Once released, the product will continue to beep 5 more times. Before the beeps stop, a
signal will be sent triggering the alarm.
Hold a cotton wick at the side of the alarm and gently blow smoke through the alarm until the
smoke triggers the alarm. You can also use smoke aerosol.
Direct Heat Test (Use Hair Dryer 1000‐1500 Watts)
Direct heat toward the alarm. Hold the heat source about 12 inches from the alarm to avoid
damage to the plastic. The alarm resets only after it has time to cool.
If an alarm fails any of these tests, see Maintenance for how to clean the alarm.
Mounting the Alarm
1. See the diagram to install the mounting base on the ceiling or on the wall. Use the 2 screws and
anchors provided. Maneuver the base so the screws are at the elbow of the screw slots and
2. Fit the alarm inside the base by aligning it over the base as shown (alarm’s alignment notch
should be slightly offset from the mounting base tamper release tab), then turn the alarm
clockwise until the alarm clicks into the base.
NFPA Recommended Locations for Alarm
According to the National Fire Protection Association (NFPA) the major threat from fire in a
dwelling unit occurs at night when everyone is asleep. The principal threat to persons in
sleeping areas comes from fires in the remainder of the house; therefore smoke alarms are
best located between the bedroom areas and the rest of the house.
Where NOT to install the Alarm
• Directly above a sink, cooker, stove or oven
• Do not locate alarm within 5 feet (1.5 m) of any cooking appliance
• Next to a door or window that would be affected by drafts (extractor fan or air vent)
• In or below a cupboard
• Where air flow would be obstructed by curtains or furniture
• Where dirt or dust could collect and block the sensor
• Where it could be knocked, damaged, or inadvertently removed
Do NOT INSTALL this alarm in a location where the normal ambient temperature is
below 40 F (4.4 C) or where it exceeds 100 F (37.8 C)
INSTALL this equipment in accordance with the National Fire Protection Association (NFPA) 72.
Clean the alarm once a year. To clean the alarm, remove it from the mounting base. You can
clean the interior using compressed air or a vacuum cleaner. Blow or vacuum through the
openings around the perimeter of the alarm. The outside of the alarm can be wiped with a
damp cloth. After cleaning, test the alarm by pushing the Test button. If cleaning does not
restore the alarm to normal operation you need to replace the alarm.
WARNING: READ THE FOLLOWING CAREFULLY
• NFPA 72 states: Fire‐warning equipment for residential occupancies are capable of
protecting about 50% of the occupants in potentially fatal fires. Victims include the
elderly, children, and the physically or mentally impaired. Victims include any person
that cannot escape even when warned early enough that escape should be possible. For
these people, other strategies such as protection‐in‐place or assisted rescue or escape
would be necessary.
• Studies show that Smoke/Heat Alarms may not awaken all sleeping individuals. It is the
responsibility of individuals in the household that are capable of assisting others to
provide assistance to those who may not be awakened by the audible alarm or those
who may be incapable of safely evacuating the area unassisted.
• A battery‐powered alarm must have the specific battery type installed, be in good
condition, and be mounted properly.
• The use of alcohol or drugs may also impair one’s ability to hear the audible alarm. For
maximum protection, ensure that an audible alarm is installed on every floor of the
• Smoke/Heat Alarms only provide protection to the residence if smoke actually reaches
the alarm. The Smoke/Heat Alarm is not a substitute for an insurance policy.
Home owners and renters should have adequate insurance to protect their properties.
• Make a Family Escape Plan. Draw a map of your home showing all doors and windows.
Discuss the plan with everyone in the home.
• Know at least 2 ways out of every room, if possible. Make sure all doors that lead to the
outside of home open easily.
• Have an outside meeting place, like a light pole, mailbox, or tree a safe distance from the
residence where everyone meets.
• Practice your Family Escape Plan or “Fire Drill” at night and during the day at least twice a
year. Only practice when every member of the house can attend.
• Practice using different ways out, if possible.
• Teach your children how to escape on their own in case you cannot help them.
• Close doors behind you as you leave.
Family Escape Plan
According to the National Fire Protection Association (NFPA) there often is very little
time between the detection of a fire and the time it becomes deadly. This interval can be
as little as 1 minute. Planning and practicing for fire conditions with a focus on rapid exit
from the residence are important! Fire drills should be held so that all family members
know the action to be taken.
If the Alarm Sounds
• Get out and stay out. Never go back inside for people or pets.
• If you have to escape through smoke, get low and go under the smoke.
• Call the fire department from outside your home.
