Product Description

Home Safety Means Gas Alarms 
If you heat or cook with propane gas or natural gas, you need to install a gas leak monitor near each gas furnace, gas stove or gas heater.  Don't trust your sense of smell: no one is awake 24 hours a day. The Safe-T-Alert Liquid Propane Gas Alarm and Natural Gas Alarm Model STA-40-411AC is easily installed.

Made in the USA, the Safety Alert gas detector is easily mounted using screws or velcro.  This is a 120V AC natural gas and propane gas detector that sounds a loud alert when gas fumes built to much less than a dangerous level. The 65 inch cord makes mounting easier.
A combustible gas detector with a gas alarm is a home safety essential if you heat or cook with bottled propane gas or natural gas. Propane safety requires a propane gas detector mounted near the floor where heavier propane gas will collect. LP gas or propane furnaces in basements are more dangerous than natural gas because fumes collect near pilot lights at floor levels. A spark from a propane furnace or a propane water heater pilot light can set off an explosion or fire when a significant propane gas leak is present. Combustible gas sensor trips at less then 25% of the lowest explosive limit for natural gas, propane gas and butane.
Note: Carbon monoxide alarms will not detect a raw gas leak.

Safe-T-Alert 40-411 Gas Alarm Features:
  • InteleCheck Circuit: No false alarms from momentary exposure to propane gas, natural gas, aerosol cleaners, hair spray and other flammable gases. An 8 second double-check circuit distinguishes a gas leak from a momentary gas exposure.
  • Long Life, Self Cleaning Sensor: Maintenance free built-in sensor. Combustible gas sensor trips at less then 25% of the lower explosive limit for natural gas, propane gas and butane.
  • Loud 85dB Alarm: Alerts for presence of a potentially dangerous gas leak.
  • Test/Reset Button: Allows you to silence alarm temporarily during ventilation. Tests all detector functions with one touch. No dangerous gas required for these tests.
  • Installation: Attach to wall with two screws. "Plug-it-in" installation. Cannot be hardwired into 120VAC. The wall transformer is required to convert the 120VAC into 12VDC.
  • Micro Current Technology: Wall transformer (120VAC to 12VDC) consumes only 3.8 watts of energy, which is about US $3.00 per year to operate.
  • 65 inch Gas Alarm Cord: Allows you to mount the gas monitor near the gas source for more accurate detection. Propane gas is heavier than air. Mount this gas alarm within 4 to 20 inches of the floor to protect against propane gas leaks. Methane gas (natural gas) is lighter than air. Mount the detector within 6 inches from the ceiling or on the ceiling at least 12 inches from a wall.
  • Approval: UL listed as a "Single Station Propane/Methane Detector" to 1484 requirements. Use this propane gas alarm or natural gas alarm for residential and unconditioned areas. Unconditioned areas include garages, boiler/furnace rooms, warehouses, barns, offices, etc.
  • Warning: Install carbon monoxide alarms in homes and businesses burning fossil fuels like coal, wood, etc. for heat or cooking. Combustible gas alarms do not detect carbon monoxide that can cause suffocation or brain damage. Free Shipping Internet sells passive card carbon monoxide monitors and 9 volt battery operated, 120 VAC, and 12V DC carbon monoxide alarms.
  • Warranty: 5 year limited warranty by MTI Industries. MTI is responsible for all warranty replacements.
  • Detector case dimensions: 5.5"W x 3"H x 1"D
  • Manufacturer: MTI Industries.
  • Note: UL 1484 listed combustible gas detectors are not detectors for minute gas leaks. Sensors and detectors are tested in a combustible gas environment and meet the UL 1484 standards for alerts of dangerous gas levels. Deliberate exposure to natural gas, butane, propane, etc. can destroy the sensor in this unit. Use the test button to test this unit, not exposure to raw gas.
  • NOTE: Carbon monoxide alarm sensors cannot detect raw gas leaks. To be protected, most homes need both carbon monoxide alarms and raw gas alarms.
  • Why do I need a combustible gas detector/gas alarm?
    • No matter how good your nose is, you may not be in the right place at the right time to notice a natural gas or propane leak.
    • Carbon monoxide alarms give NO protection against combustible gas leaks. carbon monoxide sensors detect only carbon monoxide, not raw fuel.
    • Turning off a light, setting a security alarm or closing a door spark a gas explosion or fire. Natural gas leaking from a basement furnace can leak upstairs through hollow walls.
    • Gas can leak into homes via sump pits, inbound water lines or a natural gas well under your home.
    • Each gas appliance is a potential source of a gas leak. Each gas appliance needs its own gas detector.
    • Note: Add an electrical outlet if needed to install the Safe-T-Alert combustible gas alarm correctly. Mount 4 to 20 inches above the floor for propane leak protection. Mount within 6 inches of the ceiling or on the ceiling at least 12 inches from a wall for natural gas leak protection.
