QUICK and EASY home security gas detector
As per the instructions, once I plugged in the unit, I used a handheld lighter, lit the flame, then blew out the flame while still holding the lighter down to allow some of the gs to leak out. I held it near to the sensor, and after 5-7 seconds, the alarm went off. The readout on this alarm unit is very easy to read, and the setup is as easy as they come! I would encourage anyone purchasing this unit to make sure you read the setup directions, to avoid any confusion, and set the unit using the instructions, above. We set this unit in our basement, to allow for additional monitoring, as some of our systems in this old farmhouse are still in the process of updates and renovations.
