Mounting and Wiring
Installation Notes
•
The communicator must be installed in accordance with the National Electrical Code,
ANSI/NFPA 70.
•
The communicator must be mounted indoors within the protected premises.
•
Do not install in air-handling spaces.
•
Do not mount the communicator on or near metal objects, as this may affect radio
communication. It is also good practice to avoid locating the communicator near
wiring such as AC, telephone, HVAC, computer data cables, etc.
•
Unshielded, 22 AWG cable is recommended for the communicator power/data wires.
•
Do not connect to a receptacle controlled by a switch.
Determining the Signal Strength to Select a Location
When choosing a suitable mounting location, understand that signal strength is very important for
proper operation. For most installations using the internal antenna, mounting the unit as high as
practical, and avoiding large metal components provides adequate signal strength for proper
operation.
You will use the communicator to determine signal strength in order to find a suitable mounting
location.
LTEM-P Initial Power Up
: Upon initial power up, the communicator LEDs blink in repeated
sequence from top to bottom indicating network initialization.
Green (REG)
Yellow (STATUS)
Red (FAULT)
Green (CELL)
Green (WIFI)
This sequence may take up to 15 minutes.
Do not reset power during this time.
When initialization is complete, the LEDs may blink (per their respective functions).
After initial network setup, subsequent resets or power ups can take up to 90 seconds.
1.
Unpack the communicator and open the case by pushing in the two bottom tabs with a
screwdriver while separating the case front.
2.
Temporarily connect the power adapter and the battery to the communicator. When initial power
up is complete, you can remove the power adapter and use the communicator on battery power to
find a suitable mounting location.
3.
Choose the installation site with the best signal quality by observing the Cell LED; it should be lit
solid. The best signal strength is usually found at the highest point in the building, near a window.
Mark the location for the communicator.
