Marcell MAR500 and MAR501 Cellular Freeze Alarm System
Cell Phone Freeze Alarm
No phone line or Internet required!
The MarCell MAR-500A is a cellular freeze alarm tha, perfect for applications without a land line. The MAR-500A is perfect for monitoring your vacation home or winter home while unoccupied. The alarm will monitor for power outages as well as temperature and humidity conditions. When power temperature or humidity falls outside your normal range, or power fails, you'll receive an email or text message to let you know so you can check it out right away.
Marcell communicates via the cellular network to the Sensored Life cloud where users can easily program the alarm points, the alarm contacts and log in at any time to monitor the temperature and humidity levels. An on board battery keeps it working during power failures.
Add an optional water sensor (SPUCK) to add water monitoring as well! MAR500A+SPUCK=MAR501
- No Phone Line or Internet required at monitored location!
- Will monitor temperature, power, and humidity.
- Will send alerts via text, email, and telephone calls.
How often does HomeSitter report in with temperature and humidity data?
HomeSitter checks current temperature and humidity against your settings every 10 seconds. If the current readings are outside of your “safe range”, an alert will be sent immediately. If readings are within your safe range, they are recorded every hour. The MarCELL then calls into the servers every 6 to 8 hours to report the previous period's hourly readings. At that point, this data is displayed on the web site in graph or chart form.
A subscription is required to monitor the property and receive alarm notifications. Service subscriptions are available on a month-to-month, seasonal or annual basis.
How does the cellular billing work?
Part of the beauty of the MAR-500A; is that you can turn the cellular connection on and off on a monthly basis so you are only paying for the coverage you need when you need it. You can do this online at any time - quickly, easily and with no hassle. Billing plans are available starting at USD$8.25 per month. Note that Marcell uses the Verizon network and requires a decent cellular signal at the installation location. Works in continental USA only.

ReviewsLove this product! I am a property manager in Minnesota, so winters can be quite a drain on our resources when we have vacant properties - driving to/from them daily/weekly/monthly to check thermostats to ensure pipes don't freeze - this product allows us to spare those trips by the click of a mouse and touch of a keypad. Thank you!
