2GIG SMKT100-345

The SMKT100-345 is a wireless smoke and heat detector designed to provide reliable life-safety protection for compatible 345 MHz alarm systems. It combines photoelectric smoke detection with a fixed-temperature heat sensor, helping detect both slow-smoldering fires and rapid temperature increases. It also monitors temperatures for freeze protection.

This detector operates on the 345 MHz wireless frequency, making it suitable for use with alarm systems that support Honeywell-compatible 345 MHz wireless devices. It is commonly paired with systems that use a compatible wireless receiver, allowing smoke and heat alarms to be reported directly to the control panel without running additional wiring. For more information on wireless alarm technology, see What Is a Wireless Alarm System?.

The SMKT100-345 uses photoelectric smoke sensing technology, which is well suited for detecting slow-burning or smoldering fires that produce visible smoke. In addition, the built-in heat sensor provides fixed-temperature detection, offering an added layer of protection in areas where smoke alone may not be sufficient. This dual-function design helps improve overall fire detection coverage.

This 2GIG smoke detector is powered by a long-life lithium battery, reducing the need for frequent battery changes. Its wireless design makes it easier to install in finished spaces, multi-story homes, or locations where running new wiring would be difficult or disruptive. Once enrolled into a compatible system, the detector can report alarm and trouble conditions to the control panel for local alerts and professional monitoring.

The SMKT100-345 is commonly used in residential security systems and light commercial applications where wireless fire protection is required. It works well as part of a monitored security system that includes intrusion and life-safety devices. Compatible panels and receivers can be found on the Alarm Grid security sensor page.
