Carbon monoxide (CO) is a colorless, odorless gas that can build up silently from hotel boilers, heaters, pool equipment, generators, or nearby vehicles. The CDC estimates that unintentional CO poisoning accounts for more than 400 deaths and tens of thousands of emergency department visits in the U.S. each year. Bringing your own portable smoke and carbon monoxide alarm is designed to add a critical layer of protection that hotels may not provide.
Carbon Monoxide Poisoning Does Happen at Hotels — Even Luxury Hotels
CO poisoning incidents have been documented at budget motels, well-known hotel chains, and luxury resorts alike. According to the National Fire Incident Reporting System (NFIRS), firefighters responded to more than 4,000 carbon monoxide incidents at hotels, motels, and resorts between 1999 and 2020. Many hotels do not install carbon monoxide detectors inside guest rooms — only 14 states currently require them by law, and there is no federal mandate.
Works With the First Alert App and Google Home — Remote Monitoring
The First Alert SC5 sends mobile alerts to your phone through the First Alert app if smoke or carbon monoxide is detected — even when you are not in the room. If you already use Google Nest products, this alarm is also compatible with the Google Home app. This allows you to monitor your room while at dinner, sightseeing, or traveling with family in separate rooms.

Hotels Are Not Required to Install CO Detectors in Every Room
Many countries, states, and cities do not legally require carbon monoxide detectors inside hotel guest rooms. Some hotels may only place detectors in hallways or mechanical areas — which may be too far away to detect dangerous CO levels in time. A personal device can help provide protection regardless of local laws or hotel policies.
Helps Protect You While You Sleep — When Risk May Be Highest
Carbon monoxide poisoning often occurs overnight, when guests are asleep and unaware of symptoms such as dizziness, nausea, or confusion. A bedside alarm is designed to provide an early warning before symptoms become life-threatening, which may be especially important for seniors, children, and anyone with heart or lung conditions.
Portable, Lightweight, and Travel-Friendly
The First Alert SC5 is battery-powered, compact (5.75” x 5.75” x 1.6”), and weighs approximately 1 pound. It is designed to pack easily in carry-on or checked luggage. No tools, wiring, or hotel permission is needed — simply place it on the nightstand in your room.
Essential for Traveling With Kids or Seniors
Children and older adults may be more vulnerable to carbon monoxide exposure. A portable alarm can help protect loved ones who may not recognize symptoms quickly or may have difficulty responding in an emergency.
Works Worldwide — No Matter Where You Stay
Whether staying in the U.S. or abroad, personal carbon monoxide protection travels with you. This is especially important in countries where safety standards and building inspections may differ from what travelers expect.
Smart Battery Alerts Help Prevent Late-Night Beeping
The First Alert app can notify you when batteries are running low, which is designed to help avoid disruptive chirping in the middle of the night and to help ensure the alarm is ready when you need it.
Clear Voice Alerts Tell You What’s Wrong
Voice alerts with Heads-Up warning identify whether the danger is smoke or carbon monoxide and can announce the location, helping travelers react quickly and correctly.
No tools, wiring, or hotel permission needed. Simply unbox, activate, and place it in your room. Takes less than 5 minutes.
First Alert SC5 Battery Smart Smoke & CO Alarm
- Unbox the alarm and insert the included batteries.
- Download the First Alert app (free) on your iPhone or Android.
- Open the app and tap “Add Device.” Follow the on-screen instructions to connect the alarm to your phone via Bluetooth/Wi-Fi.
- Place the alarm on the nightstand or desk in your hotel room. No mounting or adhesive needed for travel use.
- Test the alarm using the single test/silence button on the device or through the app.
Set Up iPhone Alerts (You + Family):
- Enable notifications: In the First Alert app, go to Settings → Notifications → turn ON. Verify your iPhone Settings → Notifications → First Alert is ON.
- Family monitoring: If family members are in separate hotel rooms, each person can install the First Alert app and connect to the same alarm for shared alerts.
- Google Home users: If you already use Google Nest products, the SC5 is also compatible with the Google Home app for integrated smart home monitoring.
- Tip: Turn OFF “Do Not Disturb” on your phone or add the First Alert app as an exception so you don’t miss alerts while sleeping.
Things to Consider
- This alarm is designed primarily for home use and is UL-listed (UL 217 9th Edition and UL 2034). Using it in a hotel room is an added personal precaution — it does not replace a hotel’s fire safety systems.
- The alarm requires Wi-Fi to send remote phone alerts. If your hotel Wi-Fi is unreliable or requires a login portal, the alarm will still sound its 85 dB local siren and voice alerts — but phone notifications may not work.
- Do not mount the alarm with adhesive or screws in a hotel room. Simply place it on the nightstand for travel use.
- TSA allows battery-powered smoke and CO detectors in both carry-on and checked luggage. However, regulations may vary internationally — check local airline and customs rules before traveling abroad.
- Replace the batteries before each trip, or when the app notifies you they are running low. We recommend Energizer Ultimate Lithium batteries, which are designed to last longer than standard alkaline batteries in smart devices.
- This product is not a substitute for calling 911 or your local emergency number if you suspect carbon monoxide exposure. If you or a family member experience symptoms such as dizziness, nausea, headache, or confusion, leave the room immediately and call for help.
