Planning for Installation

Take a moment to prepare for installation and ensure optimal communications with other system components in the space
To assess signal strength prior to and during installation, you can utilize the following:
- MES’s free range testing tool “AirSpy”, email info@magnumfirst.com for a copy of AirSpy. Requires USB 300U.
- If utilizing Mx-eBox (BACnet to IP) gateway, utilize BACnet point available for signal strength (RSSI)
Always utilize a qualified installer
Straighten antenna out and away from any surrounding metal
Create separation distance between interfering electronics such as fluorescent tube ends, ballasts, electronic transformers, and motors. Avoid mounting inside of metal enclosures.
Obstructions of metal, concrete and dense building materials will reduce the range. Mount higher and away from obstructions to maximize range.
In applications using HVAC units a Relay Contactor is required for the units per AMP rating.

If following the standard, manual pairing process, please refer to the “Learn In Procedure” section at the end of this document. If manual with default settings is the preferred method of commissioning, it is recommended this process be done prior to installation, unless access to buttons and device is possible.
For advanced configuration using AirConfig, install Mx-USR-L3 as discussed and perform commissioning process with device installed. Make sure that device is still within wireless range.

Installation

COMMON APPLICATIONS:
WARNING: TO AVOID RISK OF FIRE, SHOCK, OR DEATH, TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND VERIFY THAT IT IS OFF BEFORE INSTALLATION BEGINS. MAKE SURE THAT IT REMAINS OFF UNTIL INSTALLA-TION IS COMPLETE. PLEASE BE AWARE THAT WITH THIS VERSION OF THE PRODUCT, IT IS POSSIBLE TO HAVE MULTIPLE BRANCH CIRCUITS FEEDING THE RELAY RECEIVER.
NOTE: Read the WARNINGS AND CAUTIONS section before beginning these installation options. Read all steps for this option before taking any action to install receiver.

For in-wall installation, a wiring box must be used. For ceiling installation make wire connections inside a junction box. Ensure that the temperature in the ceiling box will not exceed 50 degrees C. For best wireless signal performance install receiver in plastic box away from floor and away from metal objects.
Connect wires as shown in Figure A. Twist wire nuts on clockwise making sure no bare wires show. Wrap connections with electrical tape.

Warnings & Cautions

HIGH VOLTAGE: A qualified installer or electrician must install this device. Follow all applicable electrical codes for installation.
Relays and receivers are intended for INDOOR use only, in dry locations with permanently installed fixtures
This device is suitable for a circuit capable of delivering not more than 20 AMP maximum
Be sure not to install this device in locations where the units are in close proximity to the light bulbs or other sources of heat, particularly with high wattage loads.
When using relays to switch a motor, overload and over current protection sized for the motor load should be provided at the branch circuit feeder supplying the motor in accordance with the NEC or CEC, as applicable for the installation location
The maximum over current protection required for the branch circuit supplying this product is 20 AMPS. When one or more motors are installed and not internally protected then an overload protective device sized at not more than 115% of the motor full load AMPS should be installed for each motor.
When using devices to control motors and HVAC equipment, which don’t respond well to the ON/OFF cycling that occurs in the “learn” mode, it is advised to configure the receivers without the motor or HVAC load connected. Instead, program the products in advance by connecting them to a light or to another load that is safe when toggling on and off.

Learn In Procedure

It is important to mention that MES devices utilize a point to point wireless topology. The devices are meant to respond only to those devices that they have been paired with, effectively ignoring all other devices. This allows for many devices to be in the same space controlling a variety of different applications without cross-talk. The process outlined below is for manually pairing the Mx-USR-L3 to compatible devices. Once complete, this device will only respond to the compatible devices you physically pair it with. Whether BASIC or ADVANCED is preferred, you can always use airConfig via a USB300U with airConfig call or email info@magnumfirst.com to down load the AirConfig software. See “Setting Up Your Device Via airConfig” at the end of this document.
