Smoke Heat & Freeze Detector

The 2Gig SMKT3-345 Smoke Heat & Freeze Detector 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 detector 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. It can also send alarm, tamper and battery condition messages to the Control Panel. It is more customizable than previous models by allowing separation of the smoke, heat, and freeze features enabling the alarm to detect one, two, or all three.


The 2Gig SMKT3-345 Smoke Heat & Freeze Detector is Smoke, heat, and freeze detection, Ability to separate the three detection features, Self-contained sounder, Supervised transmitter and status LED, Easy installation and programming, Detailed programming instructions are included in each box and can also be found on the 2GIG dealer website.

System Requirements

The 2Gig SMKT3-345 Smoke Heat & Freeze Detector works with any Go!Control security panel. If using firmware prior to 1.8, installers can select SMKT2 as the equipment code for the new SMKT3 and the system will function properly. If running firmware 1.8 or newer, the SMKT3 equipment code is available in system programming.


You can further increase the capabilities of your 2GIG security system with the 2Gig SMKT3-345. Intended for use with the 2GIG Go!Control Panel, this sensor will emit an audible, 85dB alarm and trigger a blinking red LED in the event of smoke, excessive heat or excessive cold detection. Upon emitting an alarm and triggering the LED the built-in transmitter will send an RF signal to the Go!Control Panel. This is beneficial as it allows users to see exactly where the alert is coming from in the event multiple sensors are setup throughout a home.

In the event of low battery detection from the device it will transmit a low battery message to the 2GIG control panel, emit an audible chirp every 48 seconds and flash a blinking yellow LED every 12 seconds.
