Minut A1 is Minut's smoke and carbon monoxide (CO) alarm, built for short-term rentals. It combines a certified, always-on physical alarm with connected features - remote monitoring, automated self-testing, and real-time alerts- when paired with the Minut app.
The full installation manual and technical specifications are available at https://www.minut.com/setup/a1-s.
Availability: Minut A1 is currently available in the US only for early-access customers.
How A1 works
Always on; works with or without Wi-Fi or a Minut plan:
Detects smoke and CO using the built-in alarm module, and sounds a loud local siren immediately on detection. This cannot be disabled from the app.
Detects physical tampering (e.g. being removed from its mount) and beeps a warning.
The alarm activates automatically the first time it's attached to its mounting bracket. It cannot be manually turned off.
Connected features - require Wi-Fi and an active Minut plan:
Interconnection: wirelessly link up to 10 A1 alarms per unit (within 50 ft / 15 m of each other). If one detects smoke or CO, all linked alarms sound together. A1 only interconnects with other A1 units.
Real-time alerts: push/email notifications if smoke, CO, or tampering is detected.
Automated self-testing: schedule tests (e.g. weekly, monthly, or between bookings) from Settings → "Smoke & CO alarm" in the app. Results are logged in the event log for compliance/record-keeping.
Indoor climate monitoring: temperature, humidity, and mold risk. Readings update periodically rather than in real time.
What A1 doesn't do
A1 is a dedicated safety alarm, not a replacement for the M3 sensor. It does not include noise monitoring, cigarette/recreational smoke detection, crowd/occupancy detection, or an outdoor mode. Customers using both get full coverage: M3 for noise, occupancy, and climate; A1 for certified fire/CO safety.
Batteries
Core alarm battery | A sealed, non-replaceable battery rated for 10 years, powering the core smoke/CO alarm function. |
Connectivity battery | A separate, replaceable CR123A or DL123A battery, powering Wi-Fi, the app connection, and interconnection between alarms. The app will notify you (and the alarm will chirp locally) when it needs replacing. |
Do I need a Minut plan?
A1 can be added to any existing Minut rental unit at no extra subscription cost.
For a property not yet on Minut, a plan is required to unlock the connected features. Without a plan or network connection, A1 still detects smoke and CO and sounds its local siren.
Installing the A1 alarm
Download the Minut app (iOS/Android) and log in, or create an account if you're new to Minut.
Mount the bracket: secure the plastic mounting bracket to the ceiling using a 3/16 in (5 mm) drill bit. Keep the alarm itself away from the area while drilling to protect it from dust.
Install the battery that came with the alarm - this powers Wi-Fi/connectivity only and doesn't affect the core alarm.
Attach the alarm: twist it onto the mounting plate clockwise until it clicks. It turns on automatically. Give it a tug to confirm it's securely attached.
Finish setup in the app while staying in the same room, then press the test button - a successful install sounds a loud siren.
Where to install:
Indoor only. Do not install in bathrooms, porches, kitchens, or any area exposed to condensation, water, steam, or direct sunlight.
Never install outdoors.
Keep at least 5 ft (1.5 m) from any cooking appliance.
Avoid moisture, direct sunlight, and high heat.
Center of the ceiling is best for reaction time; no closer than 20 in (50 cm) to a corner or wall.
Smoke/CO alarm placement rules vary by state - check local requirements. General guidance: one alarm per floor and one per sleeping area, at minimum.
FAQs
Do I need Bluetooth to install it?
Yes - turn on Bluetooth on your phone; the app guides you through the rest.
How do I turn it on/off?
It activates automatically when first mounted (this is also when the 10-year battery starts). It cannot be turned off.
