The 3Gig company has an excellent reputation. Most consider their products better or equal to anything else in the marketplace. The company continually refines existing and develops new sensors and cameras compatible with home security systems using their consoles. Easy to install and link to the Go!Control panels, the technology, complements the do-it-yourself home security market that Link Interactive targets.

Link openly markets and sells through Costco and online the most current home security technology that 2Gig has. Link Interactive also keeps current with the latest smart home appliance, Z-Wave products and offers them to their customers.  To see how Link Interactive compares to other well-researched home security systems read our Link Interactive review.

Overview of Detectors

Smoke detectors are the most common detectors found in homes. The sensor inside detects smoke from a fire and sets off the siren. Heat detectors will detect the heat from flames rather than smoke. When the temperature gets above a certain level, the siren sounds.

Link Interactive offers three types of detectors. One of them, the SMKT3, combines heat smoke and freeze sensing all in one unit. The company sells a temperature only detector and a carbon monoxide unit also.

Link Interactive Smoke Heat Freeze DetectorSMKT3 Smoke/Heat/Freeze

The SMKT3 combines freeze detection for the first time with smoke and heat. This latest 2Gig product adds to what was one of their original products, a combined smoke and heat detector. Freeze sensors are a separate component used by most other home security companies and 2Gig has them available for sale. The SMKT3 provides the user with the ability to use to detect one, two or all three. The SMKT3 lets you do this by giving you the ability to turn on or off each separate component. If, for example, you installed it close to a bathroom, you could disable the photoelectric cell but the detector would still detect heat and freezing conditions.

This detector weighs about one pound, and its dimensions are 5.6 x 2.4 x 5.6 inches.

Battery Installation

The SMKT3 uses 3 AAA lithium batteries with a battery life of 1-3 years. Changing the batteries requires some care. Located at the base of the detector, you need to twist the base counterclockwise to access the battery compartment. Once you remove the batteries, you must wait at least 20 seconds before inserting the new ones. This allows time for the system to completely power down the detector. If you inset them too quickly, you may get an error reading, as the system will not be able to register that they now have a new, fully-charged power source.

Once the new batteries are installed, you should the green LED should blink once every 12 seconds.

Smoke Detection

The 2Gig smoke detection component works by using a photoelectric sensor as do most home smoke detectors. The small battery-powered light source emits a beam of light at a 90° angle to the sensor. Whenever enough smoke enters the detector, the smoke will reflect some of the light onto the photoelectric cell, which then completes a circuit to activate the siren.

This is why you should install any smoke detector at least four or five feet away from a bathroom. Any particulate matter, including water particles in fog or steam from a shower, can reflect enough light to set off the photoelectric cell.

Heat Detection

Most heat or fire detectors work by alarming once the temperature by the detector reaches a certain number of degrees. Other also alarm by using the rate-of-rise. The 2Gig version in the SMKT3 uses both. It will send a signal whenever the temperature reaches 125° Fahrenheit (F) for three minutes or more. This temperature must happen three times.

It also alarms when the temperature rises 10° F or more in one minute.

Freeze Detection

You can purchase separate freeze or temperature sensors. Most home security systems offer them. The 2Gig company has integrated this sensor into the SMKT3. It sets off the alarm if the temperature dips to 40° F or lower for three minutes, three times (total nine minutes at 40° F or below.


Programming this detector can be a bit tricky if you want all three detection modes active. You need to program each function as if it were a separate sensor assuming you wish to enable all three detector capabilities in one unit. This means it needs a sensor loop number assigned, and each set as part of a separate zone.

Remember not to set any delay in response for this type of sensor. The alarm delay must be set at zero.


Place the Go!Control panel in test mode first. To check the overall functioning, press and hold the test button for about six seconds. You should hear four beeps. After you hear the beeps, release the test button. You will hear five more beeps. The console should indicate that an alarm signal was received.

For a smoke test, you have to use a burning wick or a smoke aerosol and blow smoke through the detector. The alarm should sound.

The best thing to use for a heat test is a hair dryer. Hold the dryer about 12 inches away from the detector. The alarm should sound within a minute or two. The alarm may sound for some time until the sensor has had time to cool off. The only way to stop it is to remove temporarily the batteries until the air temperature inside the unit drops.

5809 Wireless Heat Detector

This sensor works like the heat detecting component in the SMKT3. It will signal an alarm if a particular temperature is reached, or there is a temperature increase of a certain number of degrees in a set time frame.

However, the actual sensing parameters are different from that in the combined model. The temperature must reach 135° F or increase more than 15° per minute.

TestingLink Interactive Wireless Heat Detector

To test the sensor, press and hold the test button for four seconds. The LED should flash from four to seven times if it is functioning properly. If it does not flash or flashes only once, reset the unit and attempt the test again. If you get the same indication, the detector must be replaced.

If the LED flashes two or three times, you should clean the sensor. If it flashes eight or nine times, the detector sensitivity is set too high. Make sure the battery compartment is firmly closed and the plastic housing is firmly in place. If the condition persists, you may have to replace the unit.

CO3 Wireless Carbon Monoxide Detector

This 2Gig product should last about five years. When the unit reaches the end of its useful life, the yellow LED light starts blinking every 23 seconds, and the unit will chirp every 45 seconds. You must replace the unit.

As long as the green LED flashes once every 12 seconds, the unit is functioning. You should still test it through the Go!Power test cycle once a month.

Overview of Smart Home Appliances

Link Interactive allows the use of any Z-Wave compatible smart home appliance. Since Z-Wave is the standard used by most home appliance manufacturers, many different types, models and brands will connect with the Link systems.

Link stocks a number of different smart home products.




How Z-Wave Works

Z-Wave technology wireless links appliances and their controls through one central console. Z-Wave transmitters are tiny and have a range of about 100-feet, line-of-sight (no obstructions). Essentially that gives you about a fifty-foot transmission radius in the average home.

However, Z-Wave systems connect or mesh together, creating a built-in repeater. You can have a Z-Wave appliance 200 feet or more from the Go!Control panel as long as there is another Z-Wave component in-between. The one in-between will act as a repeater, and the console will be able to link and control both.

There is a limit to the number of Z-Wave appliances that can repeat the signal of the component furthest from the control panel. If you have more four, the signal does not repeat. Given each smart home appliance could theoretically be 100 feet away from each other, given you a 500-foot range unobstructed, most homeowners will not have any connectivity problems.

If you do have problems connecting due to a large home or objects or walls that block the signals, there are Z-Wave repeaters available that can boost the signals of all the smart home appliances.

Smart Thermostat

This 2Gig product allows you to perform all the functions related to your HVAC and heat pumps through the home security panel. You can set the parameters to turn up or down the temperature at a preset location, using its Geo-services ability when approaching your home from work each day. You can also change settings or turn the system on or off remotely.

Z-Wave Door Locks

Link has three electric deadbolt offerings from two companies. One built by Yale, a touchscreen deadbolt and two, a deadbolt and door lever, from Kwikset.

Installing them should not require drilling. Each is made to fit standard exterior and interior doors. All indicate low battery by alerting the Go!Control panel and, if configured, sending a text to the user.

Each lock costs $200 or more.

Yale Touchscreen Deadbolt Door Lock

This lock comes in three colors, bronze, brass and nickel. You unlock the door by pressing a touchscreen code set by the user. You can also remotely lock or unlock the door using the app.

You can purchase an acrylic touchscreen or a tamper-resistant keypad.

The touchpad system lets you store up to 25 different entry code. A master key override comes with the lock.

At night, the 2 x 3 inches touchscreen and the keypad will illuminate. The screen remains dark with the numbers invisible in daylight until you brush your hand against the number pad.

Kwikset Z-Wave Electronic Deadbolt

Kwikset units come in the same colors as the Yale touchscreen deadbolt. The Kwikset has recessed buttons instead of a touchscreen. It has the same remote management capabilities as the Yale lock.

The backlit screen will light up by touching the lock key icon in the center. After a few moments, the light will automatically shut off.

The Kwikset cylinders have stainless steel side locking bars, racks and pins making it difficult to force open by conventional lock-picking tactics.

It comes with two keys that will override the keypad.

Kwikset Z-Wave Electronic Door Lever

The Kwikset Z-Wave Electronic Door Lever works the same way as the electronic deadbolt version. It too has the backlit screen, stainless steel parts, and two override keys.

The only difference is the lever. Once you enter your pin code, the electronic bolt retracts, and you must use the lever to open the door.

Z-Wave Light Bulbs

Z-Wave light bulbs allow you to make any lamp or light fixture into a smart home appliance. Once you screw in the 65 Watt bulb, the light can be dimmed, turned on or off, or set to turn on or off at a particular time through the home security panel or app.

Liftmaster Garage Door Control & Universal Kits

The Liftmaster remote control unit uses Z-Waves to allow you to do several things:

  • Check on the status of the door (opened or closed)
  • Remotely open the door
  • Automatically lock the door when the home security system is armed
  • Receive alerts when the door is left open

The remote can be used with most automatic garage doors manufactured after 1993.


Lamp Module with Dimmer and Small Appliance Plug-in Module

If you do not want to use a Z-Wave light bulb but would like the capability to conveniently turn any plug-in lamp into a Z-Wave appliance, this product can do it. You plug the AC power cord from the lamp into the module and plug the module into the wall. You can turn the light on and off as well as dim the bulb using your security system.

The small appliance plug-in module works the same way but with any small appliances. Plug your coffee maker into it and you can control it with your Link console or app.

SSA02 Z-Wave Siren

The SSA02 siren has a 110-decibel alarm along with a strobe light. It uses AC power with a 9-volt battery backup. If the power is cut, the siren will sound.

You can also set the siren to activate only the siren, strobe or both.

Overview of Cameras

Link sells four different cameras, three indoor and one outdoor. Each works on Z-Waves.

V721W Outdoor Wireless Camera (with night vision)

This camera, which weighs about two pounds, is waterproof. It needs AC power to operate. The HD camera gives 720P resolution for live and recorded video. It is a fixed iris with Infrared for low light conditions.

Cam-HD100 Indoor Wireless Camera (with night vision)

The 2Gig HD100 indoor camera has the same resolution and night vision specifications as the outdoor. It also uses AC power. You can mount it on a wall or ceiling or use a stand.

V520IR Wireless Fixed Camera

This camera is the newest indoor unit sold through The resolution at night has true-color at up to twenty feet. The camera will take HD video clips automatically after alarm activation or on-demand. You can watch live streaming video remotely also.
