2GIG-SMKT8-345 Product Description:


The 2GIG-SMKT8-345 is a wireless smoke/heat/freeze alarm sensor intended for use with 2GIG non-ecrypted security systems. The SMKT8-345 is powered by 2 x CR123A batteries, with a 10 year projected battery life, which eliminate the need to run power to the device. 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 2GIG control panel. This alarm detector is designed to provide protection within a 350' foot open range radius from the control panel. The 2GIG?SMTK8?345 can send alarm, tamper and battery condition messages to the control panel.

The 2GIG SMKT8-345 smoke/heat/freeze detectors are designed to recognize smoke from common synthetic materials and decrease nuisance alarms from everyday cooking. Using advanced detection algorithms and a sophisticated photo-electric optical sensor, these two detectors meet the new UL standards for the year 2020. The new 2GIG smoke/heat/freeze detector has been designed to detect fire issues earlier, providing a more accurate and timely notice in the event of smoke or fire.

In addition, the SMKT8-345 sensor helps monitor and report on excessive temperature and temperature variations. A high-temperature alert is sent to the panel and the siren is triggered when the ambient temperature exceeds 134°F. A Rate-of-Rise temperature alert is sent to the panel and siren is triggered when the ambient temperature is at 104°F and rises 15°F or more in one minute, and a freeze warning is sent to the panel if the ambient temperature is below 40°F for more than one minute.

The new UL 217 & 268 smoke alarm standards bring 250 technological changes to traditional smoke detection. Meeting the new UL standards, the 2GIG-SMKT8-345 smoke/heat/freeze detector provides increased performance and better detection of smoke, including smoke from common synthetic materials found in home furnishings. These synthetic materials generally have a faster burn rate reducing escape time from an average of 17 minutes to 3-4 minutes (UL Press Release - February 2018).

Traditional smoke detectors trigger an alarm when any smoke density reached a specific level, which could have just been normal cooking events. The 2GIG-SMKT8-345 smoke/heat/freeze detector uses advanced algorithms and a sophisticated optical chamber to improve the detection of smoke particles created by some synthetic materials, separate from organic smoke associated with normal cooking events. The new technology is designed to trigger an alarm faster when synthetic smoke is detected versus smoke from cooking, adding to safety and peace of mind.

Used this in multifamily building. The combination of smoke detector and Carbon monoxide detector was sufficient to accommodate the legal requirements of the local municipality. Was able to install in each apartment and hallways. Works great.

Great product. Makes me feel safer. This is a high-quality detector that should last for many years. You will need to be able to configure it to your alarm panel that has a compatible wireless receiver.

The reason I bought this detector is that it replaced an existing one that stopped working after six years. It just slotted right in without any modifications. The housebuilder installed this model and it has worked satisfactorily until now. Good deal.

I am very pleased with this purchase. I received the item quickly. It was very easy to install. The alarm is very loud, which is important to me. I like the idea of not having to worry about battery replacement every year. I can't really comment on the battery life because it is supposed to be a 10 year battery and i haven't had it for even 1 year yet, but I am hopeful.
