Connected to pulse-output meters being used for multi-family submetering, 
the EN1501 and EN1501-XL transmitters will transmit data to an RF 
receiver that is connected to a Data Concentrator and Communicator 
(DCC-5800). The EN1501 includes a replaceable battery; the EN1501-XL 
includes a long-life battery that is not replaceable.

Connect the transmitter to the meter as follows:
1. Open the housing by pressing down on the base tab near the wiring 

thru-hole while lifting away the cover. 

2. Fully insert stripped wires into the removable header terminal.
3. Use a small Phillips screwdriver to tighten the screws that secure wires 

to the removable header terminal.

4. Attach removable header terminal (if removed) to the transmitter board 

as shown.

Note: If connecting to a meter that has polarity to its pulse output, the 
negative (–) should be connected to the outside terminal, closest to the 
corner of the board.

If you are using either transmitter anywhere except North America, you will 
need to select the frequency band for your geographic area. If you are 
using the transmitter in North America, there is no need to select the 
frequency band. All transmitters are set for North America by default.

1. Place the selection jumper included in the accessory pack on the 

appropriate frequency band selection pins (Figure 1).

• Leave the jumper off the pins to select 902-928 MHz for North 

America.

• Place the jumper on the left two pins to select 921-928 MHz for New 

Zealand.

• Place the jumper on the right two pins to select 915-928 MHz for 

Australia.

1. Use the double-sided tape to mount the transmitter to a clean wall.
2. If installing the EN1501, the transmitter can be secured a wall with the 

mounting screw and anchor. Remove the battery to access the 
mounting screw hole; press the reset button after replacing the battery.

Note: Ensure cabling enters the housing through the access wiring thru-
hole, and replace the housing (Figure 2).
