1 Overview
The EN1238D is a two button pendant transmitter, able to send two 
conditions. The EN1238D must be used with an EchoStream 
EN4000 or EN4200 serial receiver or the EN6040 network 
coordinator. In addition, the application controller (e.g. control 
panel) must be designed to accept the two conditions.

2 Installation and Startup
2.1 Install/Replace the Battery
1. Pry the housing apart at either end and pull the two halves
apart.
2. If replacing a battery, remove the old battery.
3. Install the new battery.
4. Press the Reset button to initialize the transmitter.
2.2 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, 
and must be configured for your geographic area. To configure the 
transmitter:
1. Pry the housing apart at either end and pull the two halves 
apart.
2. Place a selection jumper on the appropriate frequency band
selection pins.
• Leave the jumper off the pins to set the frequency range to
902-928 MHz for North America.
• Place the jumper on the bottom pins, marked NZ, to set the
frequency range to 921-928 MHz for New Zealand.
• Place the jumper on the top two pins, marked AU, to set the
frequency range to 915-928 MHz for Australia.
3. Press the Reset button to complete configuration.
Caution: When pressing the Reset button, make sure you don’t 
also touch the frequency band selection pins. Touching the 
frequency band selection pins while pressing the Reset button can 
inadvertently set the pendant to the wrong frequency band.
2.3 Register the EN1238D
The EN1238D must be registered with the system in order to be 
monitored and supervised. When supervised, the EN1238D will 
send a check-in message to the serial receiver or network 
coordinator.
Pendants using the 868MHz frequency range for Europe will send a 
check-in message every 12 minutes; all other transmitters will send 
a check-in message every three minutes.
Each pendant has a unique factory-programmed identification 
number. Refer to the control panel’s installation instructions for 
details on registering a transmitter.
1. When prompted by the receiver to reset transmitter, press the 
Reset button.
2. Replace the cover.
3 Operation
Caution: The EchoStream system should be tested regularly to 
ensure operation. To test the system, activate both EN1238D 
conditions and ensure an appropriate response.
3.1 Activating EN1238D Conditions
The EN1238D can send two different conditions. To send the first 
condition, press and hold either the left or the right pendant button 
for one second; to send the second condition, press and hold both 
buttons simultaneously for one second.
Condition signals are transmitted multiple times and are indicated 
by the blinking transmission LED. When the buttons are released, 
the transmitter sends an condition restoral signal.To test a 
transmitter, activate the condition by pressing the button(s). 
Inovonics Wireless recommends you test the transmitter at least 
once per week.
