MT15 Installation Guide - Indoor Air Quality w/CO2

Physical Specifications

Multicolor, multifunction LED Ring

MT15 is the first MT Sensor which can visually indicate the conditions of the environment without the use of the Meraki Dashboard. This is done via the LED Ring on the front of the device, which can represent any of the measured metrics and is configurable via the dashboard.

Factory Reset Button

On the back of the sensor, there is a pinhole button to factory reset the sensor. If the button is pressed and held for at least five seconds and then released, the sensor will reboot and it will be restored to its original factory settings by deleting all configuration information stored on the unit.

USB-C Port

The MT15 sensors have a USB-C Port on the back that can be used to provide an alternate source of power using a compatible accessory.

RJ45 Port

The MT15 sensor also has a RJ45 port for PoE on the bottom that can be used to provide an persistent source of power using a PoE switch.

Configure Your Network in Dashboard 

The following is a brief overview only of the steps required to add an MT15 to your network. For detailed instructions about creating, configuring and managing Meraki Sensor networks, refer to the online documentation (https://documentation.meraki.com/MT).

1. Login to http://dashboard.meraki.com. If this is your first time, create a new account.

2. Find the network to which you plan to add your sensor or create a new network.

3. Add the sensors to your network. You will need your Meraki order number (found on your invoice) or the serial number of each sensor, which looks like Qxxx-xxxx-xxxx, and is found on the back of the unit or included in the box.

4. Add the gateway(MV or MR) to the same network as the sensor.

NOTE: Make sure the gateway is in the same network and is online and operational.

General Guidelines

As the MT15 helps monitor the ambient air quality metrics, The following tips and guidelines should be considered when positioning your MT15:

• Mount the sensor about 6-8 feet from the ground. This will help the sensor monitor the air quality at the average height of human breath.

• One MT15 has approximately 100 sqft of coverage, meaning at least one MT15 should be installed in every 10x10ft room

• Make sure the MT15 is away from an inlet or an air vent. Higher air flow near the sensor can result in inaccurate readings.

• Ensure that the MT15 sensor is oriented in an upright position or flat with the LED ring facing down with a clear path for airflow through the vents (right and left sides).

Operating Modes

The MT15 sensors have 2 operating modes:

1. USB-C Powered - Requires a 5V; 0.2A USB-C power adapter to power the sensor.

2. PoE - 802.3af

Mounting Instructions

For most mounting scenarios, the MT15 has flexible options to provide quick and simple mounting. The instructions are as follows:

1. In order to mount the sensor on different locations, there are 2 supported orientations

   1. Wall - The mounting plate can be directly screwed onto the wall (Option C) or or on a Junction Box.

   2. Ceiling - The device can be mounted on a ceiling using the included screws, or by using a T Rail mount (Not included) (Option B), or on a Junction Box (Option A).

2. Once the mounting plate is on the desired surface, slide the MT15 sensor onto the plate.

3. Screw the Security Screw into the MT15.
