Safe-T-Alert / MTI Industries · RV Carbon Monoxide & Propane Alarm

Safe-T-Alert 35-742-WT white flush-mount 12V CO and propane alarm

The white 35-742-WT combines carbon-monoxide and propane-gas detection in a hardwired 12V RV alarm. It uses independent electronic sensors, audible warnings and LED indicators, with a flush-mount face listed at 6-3/8 × 2-7/8 inches. This is the RV CO/LP alarm, not a smoke detector or a propane shutoff-solenoid kit.

Product Description

Two sensors monitor CO and explosive propane gas simultaneously. A mute/reset function temporarily silences the warning while the prescribed response is carried out; the alarm can sound again if the hazardous condition remains. The alarm depends on an operating 12V supply and detects gas at its sensor, so placement and unobstructed airflow matter.

The flush-mount configuration recesses into a suitable wall opening. The manufacturer’s product page lists a 6.375 × 2.875 × 1.25-inch case, while the installation guide specifies a 5-3/8 × 2-inch cutout and at least 1 inch of recess clearance. Check the actual unit and opening before altering the RV wall.

Features & Benefits

  • Dual independent sensors for carbon monoxide and propane/LPG.
  • 12V hardwired power, nominal 108 mA current draw and low-voltage warning.
  • Audible warning rated at 85 dB at 10 feet, with condition-indicating LEDs.
  • Test/mute/reset control; re-alarm if a hazardous condition persists.
  • White flush-mount housing for the specified indoor RV application.
  • Manufacturer states conformity to UL 2034 RV and UL 1484 RV and the relevant RVIA/NFPA requirements.
  • Five-year service-life/end-of-life indication; limited one-year warranty.

Compatibility & Applications

  • For indoor RV use in a properly selected location; not a commercial/industrial gas monitor, marine alarm or smoke/fire detector.
  • Mount at least 4 inches and no more than 20 inches above the floor as directed by the manual.
  • Do not install behind furniture or drapes, in a closet, on an exterior wall, or within 12 inches of opening windows, exterior doors or heating/return vents.
  • Verify the 12V supply, wall opening and rear clearance. Do not assume compatibility with an existing relay, solenoid or two-power-lead detector solely because it is flush mounted.
  • The alarm must remain powered whenever the RV is occupied. It cannot protect an occupied RV with its supply or main disconnect switched off.

Frequently Asked Questions

Q: Does this detect smoke as well as CO and propane?

A: No. It is designed for carbon monoxide and propane gas, not smoke or fire. Keep the RV’s required smoke alarms in place.

Q: Does it use replaceable AA or 9V batteries?

A: No. This model is hardwired to a 12V DC RV supply. It does not work without that supply.

Q: What size opening does the flush version need?

A: The 35-742 installation guide specifies a 5-3/8-inch-wide by 2-inch-high cutout and at least 1 inch of recess clearance. Check the actual case and wall before making alterations.

Q: Where should it be mounted?

A: The manual calls for an unobstructed indoor location 4–20 inches above the floor, away from the listed draft sources and obstructions. Read all of its placement exclusions before installing.

Q: How often should it be tested?

A: After the RV has been stored, before every trip and at least once each week during use. The button checks the electrical alarm functions; it does not establish sensor response.

Q: Does detection begin immediately after power is restored?

A: No. The manual specifies about 10 minutes of CO-sensor warm-up and about 1 minute for gas. The corresponding detection is unavailable during its warm-up.

Q: When must the alarm be replaced?

A: Follow the manual’s five-year service-life record and the end-of-life signal. If the installation date cannot be established, replace no later than five years after the production date shown on the alarm.

Q: Does pressing Mute make an alarm condition safe?

A: No. Mute temporarily silences the sound; the alarm may reactivate if gas remains. Follow the emergency instructions, move to fresh air and obtain appropriate help before re-entry.

Exact flush-mount manufacturer product: Safe-T-Alert 35-742 flush-mount CO/LP alarm specifications and colour choices.

The product page’s case dimensions and the manual’s overall-case dimensions differ. Use the exact product-page measurement for selection, then verify the supplied alarm and its cutout/clearance instructions before changing an existing opening. The installation guide’s more conservative temperature range is shown above.

The limited one-year warranty covers qualifying defects for the original retail purchaser. Opening the case, misuse or improper installation can invalidate coverage; there are no user-serviceable internal parts. The alarm supplements proper fuel-appliance installation, ventilation and maintenance.
