2GIG SMKT3-345 vs Honeywell 5806W3

The 2GIG SMKT3-345 and the Honeywell 5806W3 are both wireless life-safety devices that are designed to alert others to the presence of a fire. Both devices will respond to the presence of smoke in the area. But of the two devices, only the SMKT3-345 can offers freeze and heat detection.

The SMKT3-345 and the 5806W3 are actually rather similar at first glance. Both devices are fully capable fire-safety devices that will respond to the presence of smoke. Once activated, the device will send an alert to the security system so that action can be taken. The type of action that will be performed depends on the Response Type for that programmed zone.

Although both devices operate at the 345 MHz frequency, they are not quite the same in terms of system compatibility. The SMKT3-345 can interface with both the GC3 and the GC2 Panels from 2GIG, as well as the Honeywell Lyric Controller. Meanwhile, the 5806W3 can interface with all of these systems, as well the LYNX Touch Panels and any Honeywell VISTA System with an added wireless receiver.

Additionally, the devices are different in terms of their functionality. The Honeywell 5806W3 provides smoke detection, but nothing more. It will not respond to the presence of unusually high or low temperatures. But the 2GIG SMKT3-345 offers greater functionality. It supports both heat detection and freeze detection. The SMKT3-345 will respond to smoke, fixed heat (at least 125 degrees Fahrenheit continuous for three minutes times three samples), rate of rise (at least 10 degrees Fahrenheit increase in a single minute) and low temperatures (40 degrees Fahrenheit or lower). The freeze sensor is particularly useful for alerting an end user about a broken HVAC unit that could potentially cause the pipes to freeze in the building.

Both fixed temperature heat sensing and low temperature sensing on the 2GIG SMKT3-345 behave in a similar way. Either condition must be maintained for a full three minutes before the device will respond. Three of these responses must be sampled by the detector before the heat or low temperature alarm will be activated. This means that it will take at least nine minutes for either a fixed temperature heat alarm or a low temperature alarm to be transmitted.

Please note that each function of the SMKT3-345 will require its own wireless zone on the panel. This means to get the full functionality out of the SMKT3-345, three different wireless zones are needed - one for smoke, one for heat and one for freeze. But the 5806W3 will only require the one zone for smoke detection.
