Indoor Water Leak Detection Sensor

Description

The MT12 water leak detection sensor helps protect your critical infrastructure from failed HVAC systems, adverse weather conditions, and leaky pipes that can cause network downtime and equipment failure.

Overview

IT infrastructure helps keep businesses running smoothly. From maintaining a comfortable working environment to powering IT operations, such appliances are the backbone of any business.

Protecting this critical equipment from potentially dangerous conditions is key to minimizing business interruptions and downtime. The Cisco Meraki MT12, a water leak detection sensor, can detect the presence of as little as 3 mL of liquid on its 8’ sensor cable, helping ensure safe operating conditions.

Simple sensors.
Powerful Meraki platform.

The Meraki MT12, part of the MT sensor family, cuts the complexity of traditional sensor systems by eliminating the need for separate gateway and management software. MT sensors use existing Meraki MR access points or MV smart cameras in the same network as gateways, automatically connecting and speeding up deployment timeframes. Powered by the Meraki platform, the MT sensors are fully cloud-managed. Real-time visibility through the Meraki cloud dashboard and mobile app, along with flexible alerting options, keep you up-to-date wherever you are.

Once in place, MT12 will continuously monitor your environment. If your HVAC system malfunctions causing leaks, or pipes freeze and burst, MT12 is there. Create customized alerts to notify you of changing conditions so you can take action and prevent network outages, premature equipment failure, downtime, or product loss.

WARNING

We recently discovered a manufacturing error with the MT12 that affects reliability.

We will be notifying customers of this issue on December 10, 2021.

Detail On The Issue:

All MT12 sensor water leak detection cables were not properly manufactured to specification. As a result, some cables may appear to work correctly, but there is no guarantee that the presence of water will be reported successfully every time. This issue has been present since the launch of MT12 and affects all MT12 units that have been sold.

Recommended Customer Action:
We are recommending that customers stop using the MT12 sensors to detect water immediately. We are investigating our options for resolution and will be updating you and our customers as more details become available.

Resolution Timing:
We are working towards a resolution and will send a follow-up communication to our sales and support teams, partners, and customers as soon as possible.

Orders can still be placed for MT12s. However, the ship date has been set to 9/99/99 to signal an extended lead time. Orders will not be fulfilled until MT12s with new and properly functioning cables are in inventory.

Thank you in advance for your support,

MT FAQ

Licensing

How does licensing work?

MT sensors require a dashboard license to operate, however, the licenses are not hardware-SKU specific.

How does the free licensing work?

Similar to the free MV sense licenses, Meraki provides five free licenses for MT sensors to all new and existing organizations, and these licenses do not expire. Note that these licenses cannot be transferred to another organization in either co-term or PDL model.

Connectivity

How do MT sensors communicate with the Meraki dashboard?

MT sensors uses Bluetooth® Low Energy to communicate with Meraki IoT gateways. Supported IoT gateway devices are second-generation MVs and Wi-Fi 6 MRs. A full list of supported gateways is below.

Do MT sensors support Wi-Fi 5 (802.11ac Wave 2) APs as gateway?

Yes. The MT functionality was ported to support Wi-Fi 5 APs as a gateway. The minimum firmware requirement for MT support on Wi-Fi 5 APs is MR 28.6+. Please refer to the list of compatible gateways for accurate and up-to-date information.

How does the sensor connect to its gateway?

As long as the minimum requirements are met as per the MT Installation Guides and the sensor is within range of the gateway, it will automatically connect to any gateway that picks up the Bluetooth Low Energy advertisement of the sensor.

What happens when MTs can’t communicate with the Meraki dashboard?

MT sensors have onboard storage that will retain approximately the last five days of data. Upon reconnecting to the Meraki dashboard, all data points will be uploaded.

Sampling rate and frequency of connections

In order to conserve battery life, MT sensors are in sleep mode the majority of the time. They wake up at a set regular interval to connect and report data to the gateway, which in turn uploads it to the Meraki cloud. Below is the sampling rate and connections per device type:

MT10	Data sampling: 2 minutes Connection interval: 20 minutes
MT11 (w/temperature probes)	Data sampling: 2 minutes Connection interval: 20 minutes
MT12	Data sampling: event driven Connection interval: 20 minutes
MT20	Data sampling: event driven Connection interval: 20 minutes

All sensors will wake up immediately if a configured threshold has been violated or if any event occurs in binary sensors like MT12 or MT20.

Deployment

What firmware on MV and MR is required for MT to work?

How far can the MTs be placed from the MR/MV gateway?

MT sensors use Bluetooth Low Energy 4.2 to communicate with the gateway. Since Bluetooth Low Energy operates between 2.402 and 2.480 GHz, the range depends on the same principles as 2.4 GHz Wi-Fi.

How many sensors can be used per gateway?

It is recommended to have a maximum of 32 sensors per gateway to ensure connection quality.

Minimum firmware requirement for a gateway to support 32 sensors:

MR – 28.5+

MV – 4.14+

Any firmware older than above only supports eight sensors per gateway.

Are MTs rated for outdoor use?

No, MT devices are designed for indoor use only. The MT12 is IPX5-rated (can resist a sustained, low-pressure water jet spray) and has a rubber liner to separate the power/battery compartment from being splashed or exposed to water. Still recommended NOT to submerge in water, as the rating states.

What are the supported temperature and humidity ranges for the MT10?

The temperature sensor supports 0°C – 55°C / 32°F – 131°F (accuracy: +/- 0.3°C) while using the included AA batteries. The humidity sensor ranges from 0-95%. That said, it is NOT an outdoor (IP67) or harsh environment-rated product.

MT11 temperature probes supported range

Below are the specified temperature ranges of the MT11 temperature probes. Note that the operating temperature of the MT11 body is 0°C – 55°C / 32°F – 131°F.

Bare metal probe MA-CBL-TEMP-ME-1)
Range: -40°C – 55°C
Accuracy:
-10°C – 55°C = +/- 0.5°C
-30°C – 55°C = +/- 1°C
-40°C – 55°C = +/- 2°C

Glycol probe (MA-CBL-TEMP-GL-1)
Range: -40°C – 55°C
Accuracy:
-10°C – 55°C = +/- 0.5°C
-30°C – 55°C = +/- 1°C
-40°C – 55°C = +/- 2°C

Can MT10 be used to monitor temperature and humidity inside of a freezer?

The sensors are not IP rated and we do not recommend installing them inside of freezers.

Can the MT11 temperature probes be used to monitor temperature of fluids?

No. MT11 temperature probes are not rated to monitor temperature of any fluids, including water.

Do the MT10/MT11 temperature sensors need to be calibrated?

No. The MT10 temperature sensor and the MT11 temperature probes use a digital sensor that comes pre-calibrated during the manufacturing process. This means no calibration is required during the product life cycle.

What part of the MT12 is capable of detecting water?

The full length of the cable can detect water as little as 3 mL. The included cable is 8 ft long, and can be extended to 16 ft with an optional second cable attachment.

How are the MT sensors powered?

All MT products will come with AA batteries(Alkaline) included, and these batteries will last for about five years of powering the unit. That said, if you want a “permanent” powering solution, there will be a USB power adapter available at launch (MA-PWR-USB-XX) that can be used on the MT10 and MT12. The MT20 ONLY supports the battery operation.

Five years of battery life is projected based on the included 2.5V Alkaline batteries. Other types of batteries can be used, but the battery life may vary.

Alerting and Monitoring

What kinds of alerting does MT sensors support?

MT sensors support email, SMS, and Webhook alerts out of the box, no Twilio or similar integrations needed. It will also support push updates from the Meraki app. Please refer to the Sensor Alert Profiles article in order to set up alerting.

Do MT sensors support APIs?

Yes. Please visit Help > API docs on the Meraki dashboard for detailed documentation.
